Edit DDL Templates

The DDL Template Editor provides the ability to change the templates that the system uses while generating DDL from a data model. It applies the facilities of the Common Code Editor, including Intelli-sense for the various macros. For more information on Intelli-sense and the Common Code Editor, see the Editing Source Code topic.

  • User-modified and user-defined DDL Templates can be imported and exported as Reference Data (see the Sharing Reference Data topic)
  • Any user-defined templates for a database type are listed in the 'Export Reference Data' dialog in the 'Code, DDL, Transformation & CSV Templates' table, identified by the DBMS name with the suffix _DDL_Template - if no user-defined templates exist for a DBMS, there is no entry for the DBMS in the dialog
  • You must also define any appropriate data types for the DBMS and, if exporting the templates as Reference Data, you must export the 'Model Data Types - Code and DDL' table as well
