Sequence support for DB2400Dialect
----------------------------------
Key: HHH-1754
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1754
Project: Hibernate3
Type: Improvement
Components: core
Versions: 3.1.3
Environment: Hibernate 3.1.3, IBM DB2 UDB for iSeries on i5/OS V5R3
Reporter: Carey Evans
Priority: Minor
Attachments: DB2400Dialect.java
As of i5/OS V5R3 (the operating system previously known as OS/400), DB2 supports sequences, but DB2400Dialect doesn't include support for the new functionality. This support can be modelled on DB2Dialect, except that "values ..." must be written "select ... from sysibm.sysdummy1", and the syssequences view is in the qsys2 schema.
I don't know what impact this change would have on older versions of OS/400 that don't support sequences.
The attached DB2400Dialect source includes sequence support, with some additional minor corrections for timestamps on i5/OS.
