| description | The present application provides an SQL statement control method and apparatus. According to embodiments of the present application, a user of a database system can configure several control strategies and provide the control strategies to the database system, and the database system can perform control operation on an SQL statement that hits the control strategies. The control operation herein may specifically be that: if a waitable condition specified by the control strategies is satisfied, the SQL statement that hits the control strategies is added to a waiting queue corresponding to the control strategies. The database system can sequentially execute the SQL statements in the waiting queue on the premise of keeping that the current concurrency number does not exceed the maximum concurrency number specified by the control strategies.
