Table DDL Transformation Scripts

Lets you create, test, and debug scripts that can be included in generated DDL for a table. It is displayed when you select Tools > Design Rules and Transformations > Table DDL Transformations.

Active Script Set: Lists available script sets, and lets you add and delete sets in the list.

Set Details: Shows details about the selected script set, and lets you modify that set's name and description, and define one or more custom scripts for Before Create, Instead of Create, After Create, and End of Script. (Instead of Create suppresses the built-in generation of DDL for tables and related components, so that you can implement DDL generation for nonsupported databases.)

Script: Lets you display and modify details for a script within the selected script set. Select the table to test, its library (if any), and the method to use (if any). Enter and edit the actual script code in the text box.
