Oracle Discoverer DesktopWhat is Discoverer Desktop Oracle Discoverer Desktop/Plus is a data access tool. You use it to view the information in your companys databases. The whole purpose of Discoverer is to help youthe business professional view the data you want from a database, analyze it to support your business decisions, and create reports to keep track of things. How Discoverer Desktop Works We use it to view the information in your companys databases. The whole purpose of Discoverer is to help you the business professional view the data you want from a database, analyze it to support your business decisions, and create reports to keep track of things. View data in a familiar format that is easy to read and understand. Prepare reports of your analytical results and findings. Share data with others, and in other applications (such as Excel). The Discoverer Method of Data Access Your companys Database Administrator identifies all the data needed by separate business areas accounting, human resources, sales, manufacturing, projects, finance, and so forth. The Database Administrator then organizes the data for each business area. Workbooks in the business areas contain the specific data needed for your various analysis tasks. Connectivity Normal Mode

Apps Mode

Workbook Window : The workbook window is where you will do most of your work with Discoverer Desktop. It shows the data in the workbook. Four Types of Display (Layout) Table Page-Detail Table Crosstab Page-Detail Crosstab Layout Details Table Layout

The most familiar layout for data, a table, lists data in rows and columns. Typical data for tables includes lists, such as a mailing list of customers sorted by zip code or customer name, lists of income or profit from various departments, lists of products sorted by part number or part name, and so on.

Table Layout with Page Details

A table layout with page details is a table with multiple pages of data, where each page shows various portions of the data in detail. You set the criteria for displaying portions of data in order to see exactly what you want on each page. Usually you use this type of layout to study data details in a specific, recurring way. For example, in the Video Store data you may always want to see monthly profits per region. In that case, each page would show one regions profits each month. Crosstab Layout A crosstab, short for cross-tabulation, relates two different sets of data and summarizes their interrelationship in terms of a third set of data. Every crosstab has at least three dimensions of datarows, columns, and data points. In Discoverer, crosstabs can show the interrelationships between many dimensions of data on the various axes. A crosstab layout has three axes: side axis, Because each axis can hold several data items, a crosstab can display many dimensions of data. Page Detail Crosstab Layout A page detail crosstab layout is a crosstab with multiple pages of data, so you can group the data on separate pages. You set the criteria for displaying portions of data in order to see exactly what you want on each page, Crosstab Layout with Page Items

(a) Page Axis. In this sample it contains a single data item--Department. (b) Top Axis. This top axis contains two data items--Year and Profit. (c ) Side Axis. This side axis also contains two data items--Region and City. Axis Items The page axis, top axis, and left axis on the workbook window represent the data in your database that have a relatively few, discrete values associated with them. Axis items represent data that you can pivot on a crosstab worksheet or that can be column headings on a table When creating a new worksheet, you identify the data that become axis items. Data Points The data points of a table or crosstab are the data in the "body" of the worksheet. Data points are the data that you want to use for analysis purposes or to see listed on a table. v Think of a workbook as a binder file with specific data for specific tasks. v The workbook has pages, or worksheets, that contain data for the specific tasks. v For example, if the workbook is for sales and profit data, one worksheet in it might be a table listing your profit for sales versus rentals. Another worksheet might be a comparison of your profit over the last two years by sales region. v To simulate with Excel, Excel file is Workbook and Sheets in the excel file are Worksheets Building Workbook/Worksheet The basic steps to create a new workbook or worksheet are as follows: Navigation File > New

Required Steps v Select the type of display for the new worksheet or workbook. v Select the data that belongs on the worksheet or in the workbook. Optional Steps v v v v Arrange the data on a table or crosstab layout. Sort the data (for tables only). Select conditions to apply to the data. Select calculations to apply to the data.

Selecting The Data

This dialog box lists the data in the business area that you can use to build the new worksheet. To include data on the new worksheet, you move it from the Available column to the Selected column. Select relevant columns from the table for sample report Aggregations

Mathematical functions to aggregate the data Text Items- Such as Customer Name, the typical aggregations are Count, Max, and Min. That is, you can count the number of text items, or find the highest or lowes t (where A might be the highest and Z the lowest). Numeric Data- The typical aggregations are Sum, Count, Max, Min, Average, and Detail. For example, you can find the Sum or Average of the numeric data with the aggregation. The aggregation in boldface type is the default. The database administrator sets which aggregation is the default. Arranging Layouts To change the layout of items in your worksheet click and drag them to the desired location Conditions Press button New to add conditions. Our sample report does not have any conditions.

Data Sorting- Tabular Layout v Specifies how data in the current table should be ordered. v This step only applies to tables. Apply sorting type in the sample report for tabular layout Calculation v Calculations defined for the items added to the Selected list appear in the final dialog box. v You can select the calculations as part of the new worksheet or workbook, or create new calculations.

You can send all or part of your workbook in an email. File > Send Exporting to other Application You can export tables and crosstabs in a variety of formats to open them in other applications. File > Export

Scheduling Manager With the Scheduling Manager you can see the results of a scheduled report, schedule a new report, reschedule a report, or edit a reports schedule. a. Discoverer reports scheduled to run. The clock icon indicates that the reports are scheduled to run at the time specified by Date and Time. b. Completed Discoverer report ready to open. File> Manage Workbooks> Scheduling

Schedule Workbook The Schedule Wizard lets you schedule a workbook (or part of a workbook) to run at a later time. This is helpful if your query is going to take a long time Scheduling a workbook to run later allows you to keep working now and get your data later without even being at your computer. You can even have the same workbook run on a regular basis so you can update the data on a regular basis without doing any additional work.

File> Manage Workbooks> Scheduling

Sharing Workbook Sharing a workbook grants other people access to it to view, analyze, and print the data. You can share workbooks with other people by setting up sharing two ways: Assign a group of people who can share one of your workbooks. Assign one or more workbooks that one other person can share with you. File> Manage Workbooks> Sharing

Retrieving/Count All Rows Rows for tables are fetched from the database incrementally in groups. The number of rows in each group is specified in the Options dialog box based on the value set in the option

Retrieve data incrementally in groups of.Click the Query Governor tab on the Options dialog box to see that option (Sheet> Edit Sheet> Options) To override that setting you can retrieve all the rows at once instead of incrementally (Sheet > Retrieve All Rows). ****Retrieving all rows applies only to tabular style reports. To count the number of rows (Sheet > Count All Rows), A message will display the total number of rows. Refreshing the Worksheet Refreshing a worksheet re-queries the database and displays the worksheets data based on any new data. A primary use of refreshing a worksheet is when youre using Discoverer in conjunction with real-time data. To refresh a worksheet (Sheet > Refresh Sheet) Parameters Parameters are placeholders used instead of specific values in the definition of a condition. Parameters offer choices of condition value at the time the data loads. When you open the workbook, you will be prompted to enter a value and the results you receive will be specific to that value. Creating Parameters Parameters dialog box enables you to define Parameters, which are placeholders used instead of specific values in the definition of a condition. You can create Parameters at two levels: 1. Workbook level - Here, the Parameter applies to all worksheets in your workbook. 2. Worksheet level - Here, the Parameter applies to the current worksheet only. Tools> Parameters

Parameters are activated when used in an active condition. If you check the option Create condition with operator in the New Parameter dialog box, a new condition is created and activated. To deactivate a parameter, deactivate the condition. Deleting the condition or deleting the parameter also deactivates the parameter. Tools> Parameters Setting Options- Formats The Options dialog box offers a wide variety of options for setting operating features, formatting, and other aspects of your worksheets. The give tab Specifies default formatting for sheets. You must exit and restart Oracle Discoverer for new settings to take effect. Tools> Options The Dialog box displays options for viewing different types of files, and for opening workbooks. Click the Viewer check boxes if the worksheets include files with videos, images, and sound (audio). Those viewers open automatically from within Discoverer to run the files. Tools> Options

Setting Options- Query Governor Displays options for maximizing the efficiency of working with larger worksheets, Limiting the amount of time a query runs, and Limiting the number of rows retrieved. You can also choose whether to use Summary data to improve the performance of Discoverer. Tools> Options Setting Options- Table/ Crosstab This dialog box displays options for the overall table or crosstab layout. you can add or remove gridlines, column headings, row numbering, and so forth. Removing various table or crosstab features is particularly helpful when printing a worksheet as a report. Tab options differ according to whether your worksheet is a Tabular or Crosstab worksheet. Tools> Options Setting Options- Cache This dialog box displays options for the memory cache, disk cache, and cache directory for Discoverer. Generally these options should not be changed without assistance from the database administrator. Tools> Options Setting Options- Connection This dialog box displays options for setting the EUL types that can be used. you can also change the default Gateway User ID and Foundation Name, (see your Discoverer Administrator for details). Tools> Options Setting Options- Advanced This dialog box displays options for configuring Automatic Querying, Fan-trap Detection, and Multiple Join Path Detection. When you open Workbooks, Discoverer can run queries automatically or not, or can request confirmation before running queries. Tools> Options Setting Options- EUL This dialog box displays the default EUL setting. Use the option on this tab to select a default EUL (End User Layer). Check with your database administrator for the correct EUL to select. Tools> Options Command Line Options You can run Discoverer from the command line and perform a limited number of tasks automatically, for example, opening or printing a Workbook. To run a command line option: 1. From the Windows Start menu, choose Run. 2.

Discoverer 10g Installation steps Discoverer 10g Installation stepsOracle Business Intelligence 10g Release 2, a key component of Oracle Application Server 10g Release 2, is an integrated business intelligence solution supporting intuitive ad hoc query, reporting, analysis, and web publishing. Discoverer 10.1.2 is tightly integrated with Oracle EBusiness Suite Release 12. Release 12 users can use Discoverer to analyze data from selected business areas in Financials, Operations, and Human Resources etc. The following are the Discoverer 10g Installation steps for Oracle R12 environment. 1] Install Oracle Business Intelligence Tools 10g (10.1.2.0.2) using below link http://www.oracle.com/technology/software/products/ids/htdocs/101202winsoft.html First right click on the zip file (as_windows_x86_bi_tools_101202). Extract all to a directory on your PC. Click on the Extracted folder which has the same name (as_windows_x86_bi_tools_101202). Click on the 10g set up icon and follow only the default settings. This installation creates a home BIToolsHome_1 (If Default location is selected during install). 2] Apply the latest certified Discoverer Plus and Viewer Patches To upgrade to Oracle Discoverer 10.1.2.2 Apply the patch: 4960210 To upgrade to Oracle Discoverer 10.1.2.3 Apply the patch: 5983622 Follow the installation instructions provided in the patch README to install the patch on your Discoverer 10g Server and to check supported operating systems.

3] Copy Database Connection file Discoverer needs access to the Database Connection (dbc) file for the database you wish to connect to. A dbc file is a text file which stores all the information required to connect to a particular database. First identify the Oracle Home for Discoverer. For example: If you could find dis51usr.exe under the directory D:\oracle\BIToolsHome_1\bin. Then the Oracle Home is D:\oracle\BIToolsHome_1 Create a folder named secure in the ORACLE_HOME directory (i.e. D:\oracle\BIToolsHome_1\Secure). Then copy the dbc file from the $FND_SECURE directory of the E-Business Suite Release 12 instance you are setting up Discoverer with to the Discoverer 10.1.2 ORACLE_HOME\secure directory you just created. Save the dbc file in lowercase. 4] Update tnsnames.ora file On your standalone Oracle Business Intelligence Server 10g Release 2 node, update the file ORACLE_HOME/network/admin/tnsnames.ora and include the tnsnames entry to connect to your Oracle E-Business Suite Release 12 database. Use the same entry as exists in the tnsnames.ora file on your Oracle E-Business Suite Release 12 application tier server node. 5] Set the Environment Discoverer requires Windows Environment variables to dynamically retrieve the location of the .dbc file on the PC. Open Windows Control Panel and double click on the System icon. Select the Environment tab and create two new System Variables. FND_SECURE = ORACLE_HOME\Secure FND_TOP= ORACLE_HOME Note: The Oracle Home is the one identified in step 3. 6] Restart the PC and you should be able to connect to Discoverer in an Oracle Applications mode. Note: When you are connecting to Discoverer for the first time, then Goto Tools > Options. Check the proper EUL in the Connection Tab.

Database Query for DiscovererAll discoverer folders and workbooks that you create get stored in database. You can use the below

queries to find the details. Find your Discoverer Workbook and Folder Details from Database: 01 select fu.user_name owner, 02 doc.doc_id "Document Id", 03 doc.doc_name "Document Name", 04 doc.doc_developer_key, 05 doc.doc_folder_id, 06 doc.doc_created_by, 07 doc.doc_created_date, 08 doc.doc_updated_by, 09 doc.doc_updated_date, 10 min(qs.qs_created_date) first_acc, 11 max(qs.qs_created_date) Last_Acc 12 from disco_apps.eul5_documents doc, 13 apps.fnd_user fu, 14 disco_apps.eul5_qpp_stats qs 15 where '#'||fu.user_id = doc.doc_created_by 16 and qs.qs_doc_name=doc.doc_name 17 and qs.qs_doc_owner=fu.user_name 18 and doc.doc_created_date New to create a new complex folder. 4] Click the new folders icon on the Data tab and choose Edit | Properties. We can give a more descriptive name, Description and Identifier Name for the new folder. 5] On the Workarea: Data tab, Drag an item from any folder in any open business area to the new folder. Or you can simply do copy and paste. Tip: You might find it easier to drag items between folders if you have two Workareas open. To open a second Workarea, choose Window | New Window (Shift W). Note: When you add an item to a complex folder, the folders that it comes from must be joined to the folder of at least one other item already in the complex folder. If this is not the case, Discoverer Administrator will display an error dialog. Note: If you select items from two folders that are joined using more than one join, Discoverer displays the Choose Join dialog. Here you can select one or more joins and click OK. Note: If you select an item from a simple folder that has a join that conflicts with existing items, Discoverer will display an error and you will not be allowed to add the item. If you want to see all the joins, conditions and the workbooks that are based on your complex folder, go to Folder Properties | Dependents Tab. What is complex folder reach through? Complex folder reach through is a mechanism that enables Discoverer Plus and Discoverer Desktop users to add items to their worksheets in addition to those provided in a selected complex folder. In Discoverer Administrator you can define one or more base folders within a complex folder as reach through enabled. When a Discoverer Plus or Discoverer Desktop user selects an item from the complex folder, the associated reach through enabled base folders become available for selection in a worksheet.

It has a small LOV icon in the right side. When clicked on the LOV icon, the below window with all the Period Names will appear where you can choose one or many period names. Now the question is how to do this. You just need to do the below steps to accomplish this task. 1] Create a custom folder named Time Periods in a business area with the below query. 01 select distinct 02 period_name, 03 period_num, 04 period_year, 05 decode(period_num,1, 'January', 06 2, 'February', 07 3, 'March', 08 4, 'April', 09 5, 'May', 10 6, 'June', 11 7, 'July', 12 8, 'August', 13 9, 'September', 14 10, 'October', 15 11, 'November', 16 12, 'December', null) month_name 17 from gl_periods; 2] Select the business area in which you want to create an item class. Choose Insert > Item Class. 3] Select the LOV Item class attribute.

4] Select the above created folder (Time Periods) and choose the Period Name column. 5] Here you can select the various items of other folders that can use this item class. You can skip this stage and later you can manually assign this item class to other items. 6] Choose the defaults and click next. 7] Give a suitable name to the Item Class 8] Now go to the Item of the folder on which you created the Parameter (Period Name) and then go to Item Properties. Here you assign the item class that you have created just now. 9] If you already created the parameter in your workbook and your discover plus or desktop is open then close it and reopen. Then you can view the LOV attached to the parameter. 10] If you havent already created the parameter, then create the parameter and run the report. You can view the LOV attached to the parameter.

Registering Custom PLSQL Functions in DiscovererAlthough Discoverer provides many functions for calculation in reports, sometime we require to use custom PL/SQL functions to meet additional Discoverer end user requirements (for example, to provide a complicated calculation). For this we first need to create the functions in database through Toad or other PL/SQL editors. To access custom PL/SQL functions using Discoverer, you must register the functions in the EUL. When you have registered a custom PL/SQL function, it appears in the list of database functions in the Edit Calculation dialog and can be used in the same way as the standard Oracle functions. Note: To register a PL/SQL function you must have EXECUTE privilege on that function. You can register custom PL/SQL functions in two ways: Import automatically, by importing the functions (recommended) Manually

How to register custom PL/SQL functions automatically:To register PL/SQL functions automatically you must import them in the following way: 1. Choose Tools | Register PL/SQL Functions to display the PL/SQL Functions dialog: Functions tab.

2. Click Import to display the Import PL/SQL Functions dialog. This dialog enables you to select the PL/SQL functions that you want to import. 3. Select the functions that you want to import. You can select more than one function at a time by holding down the Ctrl key and clicking another function. 4. Click OK. Discoverer imports the selected functions and displays the function details in the PL/SQL Functions dialog: Functions tab. Information about the selected functions is imported automatically. In other words, you do not have to manually enter information or validate the information. 5. Click OK. The PL/SQL function is now registered for use in Discoverer.

How to register custom PL/SQL functions manually:To manually register a PL/SQL function for use in Discoverer: 1. Choose Tools | Register PL/SQL Functions to display the PL/SQL Functions dialog: Functions tab. 2. Click New and specify the function attributes. 3. Click Validate to check the validity and accuracy of the information you have entered. 4. If the function is invalid, correct the attributes and click Validate again. 5. (Optional) if the function accepts arguments: a. Display the PL/SQL Functions dialog: Arguments tab. b. On the Arguments tab, click New and specify the argument attributes. 6. Click OK when you have finished defining the function. The custom PL/SQL function is now registered for use in Discoverer. It is always recommended to register PL/SQL functions by importing automatically (especially if you have many functions to register), because it is easy to make mistakes when manually entering information about functions. When you import functions, all of the information about each function (for example, names, database links, return types, lists of arguments) is imported.

What is Fan Trap in Discoverer and how it handles them?

Fan Trap is a situation while running discoverer reports that return unexpected results due to a group of joined database tables. The most common manifestation of a fan trap occurs when a master table is joined to two or more detail tables independently. If you use a straightforward SQL statement to aggregate data points here, you may get incorrect results due to fan trap. Now, if you enable fan trap detection in Discoverer and if you use Discoverer to aggregate the data points, Discoverer will never return incorrect results. Example of Fan Trap: Consider an example fan trap schema that includes a master folder (ACCOUNT) and two detail folders (SALES and BUDGET), as shown below: Now lets say we need to answer the question, What is the total sales and total budget by account? Straightforward SQL statement approach:SELECT Account.Name, SUM(sales), SUM(budget) FROM Account, Sales, Budget Where Account.id=Sales.accid AND Account.id=Budget.accid GROUP BY Account.Name;

Account Sales Budget Account 1 800 1200 Account 2 130 200 Account 3 600 750 Account 4 600 600 The above results are incorrect, because they are based on a single query in which the tables are first joined together in a temporary table, and then the aggregation is performed. However, this approach causes the aggregates to be summed (incorrectly) multiple times. Discoverer Approach: If we run the query in Discoverer interrogates the query, detects a fan trap, and rewrites the query to ensure the aggregation is done at the correct level. Discoverer rewrites the query using inline views, one for each master-detail aggregation, and then combines the results of the outer query. Here are the results from discoverer which is correct: Account Sales Budget Account 1 400 400 Account 2 130 100 Account 3 200 750 Account 4 300 200 How to enable fan trap in discoverer? By default, fan trap detection is always enabled for you. If you want to disable it (however not recommended), you can logon to Discoverer Plus, go to Tools > Options >Advanced Tab and click on Disable fan trap detection. How Discoverer handles fan trap? If a fan trap is detected, Discoverer can usually rewrite the query using inline views to ensure the aggregation is done at the correct level. Discoverer creates an inline view for each master-detail aggregation, and then combines the results of the outer query. In some circumstances, Discoverer will detect a query that involves an unresolvable fan trap schema, as follows: If the detail folders use different keys from the master for the join If there is a direct join relationship between the detail folders (thereby creating an

ambiguous circular relationship) If non-aggregated values are chosen from more than one of the detail folders If more than one detail folder has a separate join relationship to a different master folder You might also like:Quote to Order Flow in Oracle Sales Quotes (Oracle ...

Saturday, 10 September 2011Documenting EUL, Discoverer Workbook, WorksheetDo you need to document EUL Schema, Oracle Discoverer Work-books, worksheets? Discoverer is a great ad-hoc and BI tool. People working and using this tool often need to document the EUL (End User Layer) but there is no straight forward ways to do it. I have seen clients run some scripts against the EUL meta data and then create a word doc file for later referencing. Lets focus on some of the key EUL tables which could be used to document the different Discoverer components. In the below examples, replace "disco" with the appropriate schema owner of EUL tables. In my case it is the disco owner and hence the examples List of Business Areas select ba_name "Business Area", ba_created_by "Creator", ba_created_date "Creation Date", ba_updated_by "Updated By ", ba_updated_date "Last Update Date" , ba_id from disco.eul4_bas where ba_created_by like 'DISCO' List of Folders select b.ba_name, f.obj_name folder_name, f.obj_id, f.obj_ext_owner Owner from disco.eul4_objs f, disco.eul4_ba_obj_links l, disco.eul4_bas b where 1=1 and f.obj_id= l.bol_obj_id

and b.ba_id= l.bol_ba_id and upper(b.ba_name) like upper('Video Store Tutorial') and upper(f.obj_name) like upper('%') order by b.ba_name,f.obj_name List of Folder Items select i.exp_name item_name, i.exp_id, i.it_ext_column, f.obj_name folder_name, b.ba_name from disco.eul4_expressions i, disco.eul4_objs f, disco.eul4_ba_obj_links l, disco.eul4_bas b where f.obj_id= i.it_obj_id and f.obj_id= l.bol_obj_id and b.ba_id= l.bol_ba_id and upper(i.exp_name) like upper('%') and upper(b.ba_name) like upper('Video Store Tutorial') and upper(f.obj_name) like upper('Products') order by b.ba_name, f.obj_name, i.exp_name List of Folder Joins select key_description from disco.eul4_key_cons where fk_obj_id_remote=100027 or key_obj_id=100027 (substitute the numeric id from the Folders obj_id (see the List of Folder query) List of Workbooks select doc_name "Document",doc_developer_key, doc_description "Description" from disco.eul4_documents View Discoverer Reports through Oracle Apps Self Service In this article we will discuss how to enable Discoverer reports to be viewed through Oracle Applications Menu structure. We will take an example report say "AR - Invoice Aging Buckets" with developer key "AR_INV_AGING_REPORT" Let us assume there is a seperate responsibility to view AR reports such as "Accounts Receivables Reports". We also assume that there is a menu (top level) called "ALL_AR_REPORTS" which is attached to this responsibility using the Define Responsibility form. Using the Discoverer User tool we share the "AR - Invoice Aging Buckets" to "Accounts Recievables Reports" responsibility. Now we will begin creating the Function and menus for this workbook. Navigate > System Administrator > Application > Function Go to the Description TAB Enter Function Name = AR_INV_AGING_REPORT_DWB

Enter User Function Name = AR - Invoice Aging Buckets Enter Description = AR - Invoice Aging Buckets We appended a suffix of "_DWB" at the end of the function name to indicate this is a Discoverer Workbook function. You may choose any other name for your function but it is a good idea to keep the function name same as the developer key for easy identification and tracking. Now Go to the Properties TAB Select Type = SSWA plsql function that opens a new window (Kiosk Mode) Maintenance Mode Support = NoneContext Dependence = Responsibility Selecting the Kiosk Mode opens the Discoverer workbook in a new window. Now Go to Form TAB Enter Parameters => workbook=AR_INV_AGING_REPORT&viewer=Y In the above we entered the workbook developer key and forcing the report to be opened using Discoverer Viewer. (If your ICX profile is set to use Discoverer Viewer then you may omit the part from "&" ) Now Go to Web HTML TAB Enter HTML Call = OracleOASIS.RunDiscoverer and then Click on the Save Button Now that we have created our Form Function we will create a new menu to hold this function and then attach this new menu to the "ALL_AR_REPORTS" menu. Navigate > System Administrator > Application > Menus Create a new menu "Aging reports" Then attach the function to this menu Now query the main menu "ALL_AR_REPORTS" and add submenu to this main menu Now we have finally linked all the pieces together. Wait a minute, just ensure that the user who needs to access this report is given the "Accounts Receivables Reports" responsibility. So when user "ARUSER" logs onto Self service signon, the user will see the "Accounts Receivables Reports" responsibility as part of the menu list. Clicking on this responsibility, the user will see the "Aging Reports" as one of the sub-menu and underneath there will be the link to the discoverer workbook. If "all is fine", clicking on the report link will launch a seperate window where user can enter parameter values and execute the report. NOTE: If the menu changes does not appear as expected then ask your DBA's to bounce the Apache middle tier. Also, make sure all the Discoverer profile values are set properly. The eul_date_trunc function information from a date. The idea is that it will "truncate" out all information EXCEPT for the element(s) that you specify in the format argument. For example if you specify eul_date_trunc(date,'mon') then you can consider the item to ONLY contain month information. Thhis is logically equivalent to saying to_char(date,'mon'). However eul_date_trunc

goes one step further than to_char in that it keeps the return type as date. This has several major advantages: It allows the user to use Oracle formatting & localization. It automatically gives you sensible ordering (i.e. The months will be ordered Jan, Feb, Mar... instead of Apr, Aug... that to_char would give you). The one disadvantage of this is that as Oracle date routines insist on certain parts of a date always being set ( Year, Month & Day ) then we have to provide defaults for these elements if they are not present in the format asked for. These defaults are 1900, Jan & 1 respectively. Contrary to popular belief, these were not chosen at random but because 1900 was a century date that started on a Monday.
