[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1984?page=c... ] Wim Praet commented on HHH-1984: -------------------------------- My guess is that the "values ..." statements for DB2 UDB must be rewritten as "select ... from sysibm.sysdummy1" for DB2 on OS/390 or z/OS. The same goes just as well for the identity id query ("select identity_val_local() from sysibm.sysdummy1" instead of "values identity_val_local()"), and as from DB2 v8 on z/OS, which supports sequences, for the sequence next/previous value select string ("select nextval/prevval for <sequencename> from sysibm.sysdummy1" instead of "values nextval/prevval for <sequencename>"). With regard to this sequence support in DB2v8 z/OS, the DB2OS390Dialect should be subclassed as well to mark that sequences are supported, and with a correct implementation of the getSequenceNextValString(String sequenceName): public String getSequenceNextValString(String sequenceName) { return "select nextval for " + sequenceName + " from sysibm.sysdummy1"; } I wonder if the getCurrentTimestampSQLFunctionName() shouldn't be changed as well in the DB2OS290Dialect.java to: public String getCurrentTimestampSQLFunctionName() { return "current_timestamp"; } instead of returning "sysdate" (I can't test right now since I don't have access to a DB2 z/OS at this moment). I've seen this in HHH-1754 as a proposed fix. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
