Answer 1

JDBC has never supported parsing delimited queries. Each invocation is one trip to the database. Perhaps you can achieve what you meant to doing PreparedStatement.addBatch() for each separate query, then executing and retrieving the two resultsets ?

Just running this as two separate queries (within one connection) should give you same results.
