>                 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).
