[Hibernate-issues] [Hibernate-JIRA] Commented: (HB-380) Use ResultSet.getGeneratedKeys() when supported by JDBC driver

[<leg...@at...>]

The following comment has been added to this issue:

       Body:
DatabaseMetadata.supportsGetGeneratedKeys()

is not available in JDBC 2.0.

Otherwise the patch looks reasonable (though it appears that some stuff might be able to be refactored up to AbstractEntityPersister, perhaps).

        Key: HB-380
    Summary: Use ResultSet.getGeneratedKeys() when supported by JDBC driver
       Type: Improvement

     Status: Unassigned
   Priority: Minor

    Project: Hibernate2
 Components: 
             core
   Versions:

Environment: JDBC 3.0 Drivers with 1.4 JDKs. MySql and DB2 both have JDBC drivers that support get generated keys.

Description:
Retrieve ResultSet of natively generated keys after inserting records into databases that provide this support. Performance is genrally better with this technique. The code change should be backward compatable with 1.3 JREs and older JDBC drivers.
