Hi,
Is there any way to get the primary key of my newly inserted record.
I tried using the statement with RETURN_GENERATED_KEYS flag set but did not quite get what i wanted. Is this the way to do it?
Regards,
SHankar.

Is it database dependent?

While the ability to generate primary keys is database dependent, the retrieval of the generated primary keys using JDBC is not.

Not all database support autogenerated keys.

The method DatabaseMetaData.supportsGetGeneratedKeys returns true if
a JDBC driver and underlying data source support the retrieval of automatically
generated keys.

The key cannot be retrieved if database does not support it.
I do not think Oracle support retrieval of autogenerated keys. Most of the cases the drivers are dependent on database (type 4 and type 2)

Not only does the Database have to support it, but the JDBC Driver has to support it as well.

You mean to say that is a must for datbase to support autogenerated key?
Then why do we need DatabaseMetaData.supportsGetGeneratedKeys () method

And so.. if the Driver supports JDBC 3.0 and Database support these keys we can use this feature. Am I correct?
