Subject [jira] Created: (DERBY-712) Support for sequences
Date Thu, 17 Nov 2005 04:09:29 GMT
Support for sequences

         Key: DERBY-712
         URL: http://issues.apache.org/jira/browse/DERBY-712
     Project: Derby
        Type: New Feature
 Environment: feature request 
    Reporter: Tony Dahbura

Would like to see support added for sequences.  This would permit a select against the sequence
to always obtain a ever increasing/decreasing value.  The identity column works fine but there
are times for applications where the application needs to obtain the sequence number and use
it prior to the database write.  Subsequent calls to the table/column would result in a new
number on each call.

SQL such as the following:
SELECT NEXT VALUE FOR sequence_name FROM sometable ; would result in a next value.
