Sequences (PDM)Locate this document in the navigation structure

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.
