InformixDialect can't populate inserted serial(4) ------------------------------------------------- Key: HHH-1073 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1073 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.1 rc2 Environment: Informix 9.4 UC 3, Hibernate 3 RC2, three seperate informix drivers Reporter: Dennis C. Byrne Informix has serial(4) and serial(8) instead of identity fields. The correct way to get the last assigned id is to fire "select dbinfo('serial8') from systables where tabid=1" after an insert of a serial(8) record, or "select dbinfo('sqlca.sqlerrd1') from systables where tabid=1" from a serial(4) record. The expression 'type==Types.BIGINT', in InformixDialect.getIdentitySelectString(), will always evaluate to true, regardless of whether the serial field is 4 or 8. Hibernate will consequently use "select dbinfo('serial8') from systables where tabid=1" for both 4 and 8. We have observed a similar problem w/ third party GIS software. There is another application developed by someone here who has informed me that he does not have this problem, but that application was written in H2. A workaround for this is to override InformixDialect.getIdentitySelectString() and force it to always return "select dbinfo('sqlca.sqlerrd1') from systables where tabid=1". This however means the app would have errors w/ serial(8).
