In this lesson you will learn:

What is Developer/2000 Tools provided by Developer/2000 to create Forms and Reports How to log on to Developer/2000 Create your first block and form based on your Student table

What Is Developer/2000?

Developer/2000 is an Oracle tool that helps you to create forms and reports based on the tables

that you have created using Designer/2000. You can use Developer/2000 to:

Design and customize your forms and reports. Add various functionality, like radio buttons, combo boxes, and list of values to make

your forms and reports more user friendly. Write triggers on your objects to add functionality to them and capture errors.

Tools Provided By Oracle Developer/2000

Oracle Developer/2000 provides four tools:

Object Navigator: In this tool you can view all your objects, add new objects andname/rename your objects.

Layout Editor: This tool helps you design your forms and reports and add various objectsto them like push buttons and list boxes.

PL/SQL Editor: This is the tool that is used to write all the codes for the triggers,procedures or functions. Menu Editor: This tool will help you create a customized menu that can be attached to

your form or report.

Lesson Summary

In this lesson you have learned:

What is Developer/2000 Tools provided by Developer/2000 to create Forms and Reports How to log on to Developer/2000 To create a data block To create a basic form based on a table that you had created in lesson 7 How to view your form in the canvas.

CHAPTER 9

this lesson you will learn how to create an end-user interface and add more functionality to thebasic form that we created in Lesson 8. Specifically, this will involve:

Creating LOVs, or List of Values, where you will connect your form to another tablefrom which the users make their selections


18/85

Creating Radio Buttons Creating Combo Boxes and Poplists Creating Push Buttons Adding triggers to the Push Buttons for inserting, deleting and retrieving records

List of Values (LOVs)

1. In this form we are designing, we will create a List of Values for major, so that the usercan select a major from the list. To do this, first we will have to create table called

Major_List.

2. To do this, go to SQL*Plus and type the following code at the SQL promptSQL> CREATE TABLE MAJOR_LIST

2 (MAJOR VARCHAR2(20));

3. Now type in the following statement to insert more data into the Major_list table:SQL> INSERT INTO MAJOR_LIST VALUES ('Accounting');

SQL> INSERT INTO MAJOR_LIST VALUES ('Info. Systems');SQL> INSERT INTO MAJOR_LIST VALUES ('Marketing');

SQL> INSERT INTO MAJOR_LIST VALUES ('Finance');

SQL> INSERT INTO MAJOR_LIST VALUES ('Decision Sciences');

4. Now, type in Select * from Major_List to view your newly created table and its records.(See Figure 9.1)


19/85

Figure 9.1: Creating table Major_List in SQL*PLUS

5. First, select LOV in the Object Navigator on Developer/2000 and click on the "+" sign onthe toolbar to your left. (See Figure 9.2)


20/85

Figure 9.2: Creating a new LOV

6. Immediately, the window for the new LOV will pop up. (See Figure 9.3)

Figure 9.3: The New LOV Window


21/85

7. Type in the following Select statement in the window to connect the new LOV to theMajor_List table that we created earlier and click OK. (See figure 9.4)

Figure 9.4: The New LOV Window with the select code

select major into :studblock.major from major_list order by major;

8. Once you click OK, you will come back to the Object navigator window. Now, name theLOV as MAJOR_LOV by double clicking the word LOV. (See Figure 9.5)


22/85

Figure 9.5: Changing the name of the LOV

9. Now go back to the Canvas View by clicking on the small picture icon just beneath theword Canvases in the Object Navigator. (See Figure 9.6)


23/85

Figure 9.6: Returning to the Canvas view

10.In the Canvas View, we will create a push button and position it right beside the Majordata field. To create the push button, select the box like icon from the toolbox, click on it

once and drop it beside the Major data field. (See Figure 9.7)


24/85

Figure 9.7: Creating a push button to place it beside the Major data field

11.After the push button has been created, then right click on the button and select PropertyPalette from the list that pops up. (See Figure 9.8)


25/85

Figure 9.8: Selecting Property Palette for the Push Button

12.Once you are in the Property Palette, remove the label, specify Iconic as Yes and in theicon Filename type Down. Click on the close button in the lower taskbar located on the

upper right corner. (See Figure 9.9)


26/85

Figure 9.9: The Property Palette for the Push Button

13.You will now return to Canvas View. Your Canvas will now look like Figure 9.10.

14.Now back in the canvas, right click on push and this time select the PL/SQL Editor. (SeeFigure 9.11)


28/85

Figure 9.11: Selecting the PL/SQL Editor of the Iconic Button

Lesson 9, page 2

15.In the PL/SQL Editor we will write a trigger that will connect this button to the tablecalled Major_List, so that when the user clicks on the button they will be able to view the

list of options. When you select the Pl/SQL Editor, the window for the new triggerselection will appear. (See Figure 9.12)


29/85

Figure 9.12: The Window with the list of triggers available to the user

16.We will write a When-Button-Pressed trigger, since we would like the code to beactivated when the user presses the button. Scroll down and select When-Button-pressedtrigger. (See Figure 9.13)

Figure 9.13: Selecting the When-Button-Pressed trigger

17.Immediately, you will see the PL/SQL Editor window. (See Figure 9.14). Type in thefollowing code in the blank space in the Editor.


30/85

21.We will now create radio buttons for the FTPT_Status to give the user an option ofcreating either Full-Time or Part-Time.

22.To do this, right click on the FTPT_Status field in the canvas view and go to its Propertypalette. (See Figure 9.18)


34/85


35/85

Figure 9.19: The Property Palette for FTPT_Status

24.Once you return back to the canvas, you will realize that the data field for theFTPT_Status is no longer visible. This is because we have specified it to be a radio groupand not a text item. To see them, we will have to insert radio buttons. Select radio button

from the tool palette on your left. (See Figure 9.20)


36/85


37/85

Figure 9.21: The Window for Attaching the radio button to a radio group

26.Now right click on the radio button and go to its Property Palette. Change the label of thebutton to 'Full_Time', change background color to gray and give the radio button a value

of FT. (See Figure 9.22)


38/85

Figure 9.22: The Property Palette for the radio button

27.In the same manner create a second radio button, attach it to the radio groupFTPT_Status, give it a label of 'Part-Time' and a value of PT.

28.Select a rectangle from the palette and draw it around the radio buttons. (See Figure 9.23)


39/85

33.Click on the List Elements tab and type in the list elements and list values. In this lesson,the list elements and values will be same and will be Fall, Spring, Summer 1 and Summer

2. (However, in the values, Summer1 and Summer2 should be typed in without spaces).

(See Figure 9.28)


44/85

Figure 9.28: The Window for the List Elements

34.Now go to Programs Run Form to view your newly created Poplist. (See Figure 9.29)


45/85

Figure 9.29: Window with the Poplist on Start_Sem

35.We will now create three push buttons and write triggers for each button. To create apush button, select the button icon from the palette on the left of the canvas and drop inthe lower part of the form. (See Figure 9.30)


46/85

Figure 9.30: Selecting a push button

36.We will change the label of the first push button in the property palette to "Retrieve." Todo this, right click on the button and go to its Property Palette. (See Figure 9.31).


47/85

Figure 9.31: Selecting the Property Palette for the push button

Figure 9.32: Selecting the PL/SQL Editor for the push button

38.Select the WHEN-BUTTON-PRESSED-TRIGGER, insert the following PL/SQL code inthe blank space of the editor and then click Compile.

beginselect studid, studname, ftpt_status, sex, start_sem, start_year, major

into :studblock.studid, :studblock.studname, :studblock.ftpt_status,

:studblock.sex, :studblock.start_sem, :studblock.start_year, :studblock.majorfrom student

where studid = :studblock.studid;

exception

when no_data_found thenmessage ('Invalid Student Id:Please enter a valid Id.');

raise form_trigger_failure;

end;

39.In the above code, we are writing a select statement for retrieving the record of a studentwith any particular student ID. If no data is found on a particular student ID, then

Developer/2000 will give an error message and raise the form_trigger_failure trigger.

Run the form and type in a invalid STUDID to check the message. (See Figure 9.33)


49/85

Figure 9.33: Error Message when invalid Student ID is entered by the user

In a similar manner, create two other buttons, totaling three push buttons.

40.Go to the second push button, right click on it and go to its property palette. Change itslabel to Insert. Now come back to the Layout Editor, right click again on the push buttonand go to its PL/SQL Editor. In it, write the following code in the When-Button-Pressed

trigger:

Commit;

Clear_Form;

41.Label the third push button as Clear. At the When-Button-Pressed Trigger, write thefollowing code:

Clear_Form;


50/85

42.Now go back to the Canvas View and Program Run Form to view your form with thethree push buttons. (See Figure 9.34)

Figure 9.34: The Form with the three Push buttons

Lesson Summary

In this lesson, you have learned how to add various objects to your form and write triggers on

them to add functionality. Specifically this involved:

Creating LOVs, or List of Values, where you connected to another table from whichusers make their selections

Creating Radio Buttons

Creating Poplists Creating Push Buttons Adding triggers to the push buttons for inserting, clearing and retrieving records


51/85

CHAPTER 10

Lesson 10

In this lesson, you will learn how to:

Create Alerts (a modal window) on a push button that will function as a warning or amessage to the users when they click the button.

Create Procedures which are stored blocks of code which can be called from multipleobjects saving the time taken for retyping codes

Creating an Alert

1. Go to Alerts in the Object Navigator and double click on it. (See Figure 10.1)

Figure 10.1: Creating a New Alert

2. Double click on the newly created alert and name it DELETE_ALERT. (See Figure 10.2)


52/85

Figure 10.2: Changing the name of the new Alert

3. Now double click on the alert and you will immediately go to its Property Palette. In theproperties:

Change the title of the alert to Delete Alert Type in the message as "Are you sure you want to Delete?" Select Stop as the Alert style You can add a third button to the alert or just keep the OK and Cancel Make sure that Button1 is selected as the default button

(See Figure 10.3)


53/85

Figure 10.3: The Property Palette for the Alert

4. To activate the alert, we will create a procedure which we will call from the delete button.To add a procedure, go to the Object Navigator and double click on Program Units.

Immediately the window for the new Program unit will appear. (See Figure 10.4)


54/85

Figure 10.4: Creating a new Program Unit

5. In the window for the new Program Unit, type in the name as Display_Delete-Alert.Make sure that procedure is selected as the type of Program Unit and click OK. (See

Figure 10.5)

Figure 10.5: Naming the new Program Unit

6. Once you click OK, you will be automatically taken to the PL/SQL Editor window. (SeeFigure 10.6)


55/85

Figure 10.6: The PL/SQL Editor window for the new Program Unit

7. In the PL/SQL Editor, type in the following code for activating the alert. You may haveto delete a couple of lines from the Editor to avoid duplication. In this code, we will

declare a number variable called return_alert. We will then set it to show the alert that wecreated earlier in this lesson called Delete_Alert. We will then write a simple if/then

statement, such that if the user clicks on OK, which is alert button 1, then

Developer/2000 will perform the deletion and commit the changes. Otherwise, it will exitthe alert window and help the users decide on their action. (See Figure 10.7 to get a view

of the code as it should look in the PL/SQL editor. Do not forget to compile.)

PROCEDURE Display_Delete_Alert IS

return_alert NUMBER;BEGIN

return_alert := show_alert ('DELETE_ALERT');

if return_alert = alert_button1 thencommit;else

rollback;

end if;

END;


56/85

8.Figure 10.7: The code for activating the alert

9. We will now add a push button to the form and then add the above procedure to it, so thatwhenever the user clicks on delete, the alert will be shown. To do this, go the Layout

Editor and add a push button to the form, go its properties, andchange the label to Delete

(use the steps used to create a push button in Lesson 9). Now go to its PL/SQL Editor byright clicking on the push button. (See Figure 10.8)


57/85

Figure 10.8: Selecting the PL/SQL Editor for the Delete button

10.At the When-Button-Pressed trigger in the PL/SQL Editor, write the following code:delete from student where studid = :studblock.studid;delete_record;

Display_Delete_Alert;

11.The last line of the code will call the previously created procedure Display_Delete_Alertand activate the alert whenever the user clicks on the delete button. The first two lines of

code delete the record for any particular student ID. (See Figure 10.9 to get a view of the

alert when the user clicks the delete button).

Lesson Summary

In this lesson you have learned how to:

Create alerts on push buttons (delete) so that when the user clicks on the button the alertis shown as a warning

Create procedures or stored blocks of code that can be called from any objectCHAPTER 11

In this lesson you will learn how to create reports based on our existing Student table.Specifically, this will involve:

Using the Data Model Wizard Using the Layout Editor to customize our reports Creating charts


59/85

Our objective will be to create a simple report that will list students along with some student

attributes. Students in this report will be categorized by major. As a starting point, let us assumethat the STUDENT table has the following rows. (See Figure 11.1).

Figure 11.1: The Student table as viewed in SQL *Plus

You may enter the data shown below using the INSERT statement in SQL*Plus covered earlierin the tutorial (see Lesson 9). For example, the following statement may be used to insert the first

row (for the student Diana with Student Id '1113').

SQL> insert into student values ('1113', 'Diana', 'PT', 'F', 'Fall', 1996, 'Marketing', 'Y');

Enter the rest of the data as shown in Figure 11.1.

Creating Reports:

1. In order to create reports, you will need to go to the Reports Builder in OracleDeveloper/2000. To do this, go to the Start button and select Programs Developer 2000R2.1 Report Builder (See Figure 11.2)


60/85

Figure 11.2: Logging on to Report Builder

2. Immediately, you will see the Welcome to Report Builder Window. Select the radiobutton for theBuild a new report manually and click OK. ( See Figure 11.3)
