XML data type for application programs

Use the Add or Edit Fields wizard to define the XML column that are used by your XML database application programs.

To use IMS™ Universal JDBC driver support for XML, you need to define the XML data type column fields for storing and retrieving XML data.

The XML database supports the following operations:

There are two types of XML fields you can define using the Add or Edit Fields wizard.

Decomposed XML field
Set the start position to 0 and specify the XML schema URL that the XML database uses.
Intact XML field
Set the start position and length to a nonzero number, specify the XML schema URL, and specify the Overflow segment name that the XML database uses.
Note: IMS Version 12 and later supports new DBD generation parameters for XML data type definitions. If you use these parameters, the Java™ metadata class already contains the XML definitions and you do not need to modify the class. If you are using the IMS catalog database, the metadata is available with a data connection instead of with a static metadata class.
