Description:
There is no way to retrieve the auto-generated 'timestamp' column through a JDBC Statement on insert/update. Getting the MySQL timestamp column the same way the primary key is returned with the parameter RETURN_GENERATED_KEYS would be beneficial to avoid having to query the server again with LAST_INSERT_ID().

How to repeat:
Create a table with a 'timestamp' column type and execute an insert/update PreparedStatement.

Suggested fix:
Include a column named GENERATED_TIMESTAMP in the result set of PreparedStatement.getGeneratedKeys() containing the first timestamp column of the table.

The driver would have to do the same query you'd do by hand....There is nothing special in the protocol that gives us this data.

JM, we are discussing your last private comment.

This report looks like a reasonable feature request for MySQL server/protocol extension.
