A sequence generator is a database object that provides incremental values within any integer range. You can specify any positive or negative increment. The DataServer supports the ORACLE sequence generator. If you add a sequence to a table in your supporting ORACLE database, you must update the schema image to reflect this addition. However there are certain limitations in supporting these sequences:1. Do not define ORACLE sequences with names ending in _SEQ unless the dataserver manual instructs you to do so. The DataServer uses ORACLE sequences whose names end in _SEQ for internal purposes.2. There are two Progress 4GL functions that provide information about database sequences, NEXT-VALUE and CURRENT-VALUE. When you use the DataServer, you can use these functions to get information about sequences in your ORACLE database, but you must use the NEXT-VALUE function first in the same session you use the CURRENT-VALUE function.
