Sequences (PDM)

Sequences are auto-incremented columns that allow you to define complex incrementations. Sequences are available for selection from the Sequence list on the General tab of column property sheets. Sequences are not supported by all DBMSs.

Note: If you generate a CDM or OOM from your PDM, then the data types of table columns attached to sequences are converted to serial numerical data types for entity properties or class attributes with the format NO%n, where n indicates the length of the data type.

Creating a Sequence
You can create a sequence from the Browser or Model menu.
Assigning a Sequence to a Column
You can select a sequence from the Sequence list on the General tab of a column property sheet. You must enable sequences with the Rebuild Triggers command.
Sequence Properties
To view or edit a sequence's properties, double-click its Browser or list entry. The property sheet tabs and fields listed here are those available by default, before any customization of the interface by you or an administrator.
