The Connection module represents an open connection to a database. Through this connection SQL statements can be executed.

For simple queries the ExecuteQuery function can be used. Similarly simple updates can be executed using ExecuteUpdate . More complex statements must use a Statement or a PreparedStatement .

Connection module commands also control transaction processing, exporting the Commit and Rollback commands.

Connection modules are created by calls to OpenConnection .
