• Overview• Anatomy of an import• Using the examples• References• Tips & tricks for working with text files
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="">
<direct-fields>

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!!
