Systems, methods, apparatuses, and program products are disclosed for granular tracking of locking queries. Upon receiving a data manipulation command associated with a row of a page, a flag associated with the page is checked to determine whether a row locking query (RLQ) may be associated with the page. If no RLQ is associated with the page, the data manipulation command is executed without acquiring a lock. If an RLQ may be associated with the page, it is determined whether an active lock is associated with the page. If no active lock is associated with the page, the flag is updated to indicate that no RLQ is associated with the page and the data manipulation command is executed without acquiring a lock. If an active lock is associated with the page, page-level and row-level locks are acquired on the page and the row, respectively, before executing the data manipulation command.
