nicolas de loof commented on DERBY-712:
---------------------------------------

I'd like to use Derby as a replacement for Oracle during development, to allow the "database
per developer" principle.

I can't change my hibernate/jpa annotations and have to set the generator to "sequence". Having
support for them in derby would be great for me !

> 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.
