Using Statement rather than CallableStatement for stored proc execution

Question

Cleary, if you need to extract output parameters from a stored procedure, then you must use a CallableStatement to execute it. However, if your stored procedure just returns a basic ResultSet, or performs a database update, is there any penalty to using a regular Statement to execute the stored procedure?
For example -
String sql = "exec testprocedure 'param1' 'param2'";
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery( sql );
vs.
CallableStatement cs = conn.prepareCall( "{call testprocedure(?,?)}" );
cs.setString( 1, "param1" );
cs.setString( 2, "param2" );
ResultSet rs = cs.executeQuery();
Any thoughts?

Answer 1

Any thoughts?You would have to look at the actual driver code for a sure answer.
But for any real database (which a stored proc suggests) I doubt there would be any difference at all. It would resolve to the same call.
