Overview

Underlying technology shared with exports,

procedures, and reports

• Requires finding the Object Identifier (OID) for the desired

table, as well as the OID for each field in that table

Anatomy of an Import

A standard import has just two components:• File to be imported• XML definition

Text file to import

“100”,“10017”,“Joe”

“101”,“23007”,“Jill”

“102","58092”,“James”

XML definition

<direct-field id="y" match="true"/> <direct-field id="z"/>

</import>

<import table-id="tblX">

Anatomy of an Import

• Update the Student table.• Text file does not include quotes.

<import table-id="tblStudent" mode="update" value-wrapper="" force="true">

<direct-fields>

<direct-field id="stdIDLocal" match="true" />

<direct-field id="stdFieldA041" />

<direct-field id="stdFieldA042" />

<direct-field id="stdFieldA048" />

</direct-fields>

</import>

<import table-id="tblStudent" mode="update" value-wrapper="" force="true">

• <import• Then let’s

choose our table

• Table-id=“tblStudent”

This field (labeled as the object identifier) can be found in the details of the database table in the Data Dictionary.

• mode=“update, insert, or both”

• value-delimeter=

• value-wrapper=• force=

Let’s dissect our first line in our import:

Anatomy of an ImportAn import definition allows pre-import criteria to be set:

• For importing Ref Table values, you must select the Ref Table.

• For importing test scores, you must select the test definition.

Example 1 – Reference Code Import

Importing new reference codes into a table:

<import table-id="tblRefCode" mode="insert” value-wrapper=“”>

<preset-fields>

<preset-field id="rcdRtbOID" match="true" source="input"

value="referenceTableOid" />

</preset-fields>

<direct-fields>

<direct-field id="rcdCode" match="true" />

<direct-field id="rcdDescription" />

</direct-fields>

</import>

Import your file!

What Happened?!

Let’s review our XML Definition for

possible errors

Example 3 – Student Program ImportImporting Student Programs

<import table-id="tblStdProgram" mode="insert" value-wrapper="">

Tips & Tricks for working with text files

TextPad and Notepad++ both have out-of-the-box

syntax coloring for XML files

Notepad++ allows XML tag blocks to be expanded and

collapsed

Both allow "block highlighting" using the ALT key when

clicking and dragging

This allows you to highlight

a column and delete it, much

like you would in Excel

Tips & Tricks for working with text filesTextPad allows search and replace (Search menu -> Replace, or

CTRL+H) to take a text file without quotes and easily add them

Replace all instances of a comma with ","

Replace all instances of a line feed \n with "\n" using Regular expressions

Add a final double-quote to the start of the very first line, and you have all text wrapped in double-quotes!!
