SQL does not support [NO]AUTO_LOCKING syntax; always uses AUTOLOCKING Explanation: A WITH AUTO_LOCKING or WITH NOAUTO_LOCKING clause was seen in a START_TRANSACTION statement. SQL does not support the syntax for either clause. SQL behaves as though WITH AUTO_LOCKING was specified as its default behavior. There is no way to mimic WITH NOAUTO_LOCKING. User Action: Eliminate WITH NOAUTO_LOCKING from your source code. The warning is generated for WITH AUTO_LOCKING also to make you aware that an explicit clause has been removed.
