>             Project: Hibernate Core
>          Issue Type: Improvement
>          Components: core
>    Affects Versions: 3.2.5
>         Environment: Hibernate Core 3.2.5ga, DB2 UDB V8 OS390 (Z/OS)

> Since version 8 of DB2 sequence objects are supported on the OS390 platform. But, the syntax for use of sequences varies between OS390 platform and the "rest".
> For retreival of next value in DB2 OS390 the syntax is "select nextval for <theSequenceName> from sysibm.sysdummy1" while in the "rest" it is "values nextval for <theSequenceName>". There migt be the case that within AS/400 environment the syntax is imilar to OS390, but I have not verified this.
> Also other differences exists..
> I've included a enhanced verion of DB2390Dialect.java that has been proven to work in DB2 mainframe environment.
