OASQLIP_execute_direct_stmt

This function executes the specified SQL statement and returns the number of rows affected by it. This function has to perform operations of both prepare and execute (parse the given statement to generate a plan for statement execution and execute the plan) if the backend data source does not support immediate execution mode.

It is recommended that the IP create a new memory tree to be used for statement prepare and execution and free the tree after completion. This function is only called to execute statements that do not return results. The client maps all SQLExecDirect calls.
