DF_FILE_LOCK_RECORD_STATUS¶
Applies to: ORAFlex SQLFlex MYSQLFlex PGFlex DB2Flex
Table locking is done during transactions to maintain atomicity. In DataFlex, this is usually done with the REREAD/UNLOCK commands. This attribute is used to get the status of a table lock. If a table is currently in a REREAD, or locked, then the attribute will return true. Otherwise, it returns false. It is a read-only attribute so no setting can be done.
