## Tracing

You may be interested in seeing the SQL statements that are generated in order to apply changes back to the database. At the top of the SDO/DAS/Relational.php you will find a number of constants which control whether the process of constructing and executing the SQL statements is to be traced. Try setting DEBUG_EXECUTE_PLAN to `TRUE` to see the generated SQL statements.
