If you are retrieving information from a database that has changed since the last transaction opening (the last start), it is important to do a commit followed by another start before calling a new function. This sequence establishes access to database changes because it refreshes the database image in memory.
Note: This function is relevant only inself_transaction
mode. In theautomatic_transaction
mode, thestart
andcommit
functions are performed automatically.stm_start_transaction();
