Two different prepared statements in one single batch

Question

I want to send two different prepared statements in one single batch.

Currently I am doing this in two as you can see in the commented lines and it works,

Answer 1

You can try execute the two statement is a single transaction, like this:

connection.setAutoCommit(false);
try {
    stmt1.execute();
    stmt2.execute();
    connection.commit();
} catch (Exception ex) {
    connection.rollback();
}

The issue is that addBatch works on a single prepared statement, see this is how you can use multiple sql statements with addBatch.
