Cancels a statement

bool sqlsrv_cancel ( resource $stmt )

After sqlsrv_cancel() has been called, the specified statement can be re-executed if it was created with sqlsrv_prepare(). Calling sqlsrv_cancel() is not necessary if all the results associated with the statement have been consumed.

Parameters:

stmt

The statement resource to be cancelled.

Returns:

Returns TRUE on success or FALSE on failure.
