Configurable database generated keys support

+ +

New boolean attribute in Config - "generatedKeysSupported" (default value=TRUE). User can set true/false for this in Config. If not set in Config, JDB Metadata API check supportsGetGeneratedKeys() is done to detect whether to use auto generated keys during insert.

+ +

This gived user flexibility to turn on/off support for database generated keys during INSERT based on the
+database vendor/driver version in use. Particularly when user is sure that the DBMS driver does not support
+autogenerated keys, he can configure FALSE value through config as below.

+ +

Note: For Derby, always assumed generatedKeysSupported=TRUE. This is because current Derby API return FALSE for supportsGetGeneratedKeys(), as it is partially implemented, but in DAS context, this support is sufficient.
