参数介绍: MySQL社区版MySQL 5.7.8开始,新增了MAX_EXECUTION_TIME这个系统变量,它用来限制SQL语句的执行时间,确切来说是限制只读SELECT语句。如果查询语句的执行时长超过这个阈值,MySQL将自动停止该SQL语句的执行。如果其值为 0,表示不启用该超时限制功能。该
其实这个系统变量之所以在MySQL 5.7.8被移除,是因为用系统变量max_execution_time替换了系统变量max_statement_time max_statement_time: Statement execution timeout value. Added in MySQL 5.7.4. max_statement_time: Statement execution timeout value. Removed in MySQL 5.7.8. 参数设置 全局级别 方法1.在参数...
ERROR 3024 (HY000): Query execution was interrupted, maximum statement execution time exceeded 此时执行查询,则会因为超过1s而被中断 PS:修改全局变量后,注意已经连接的会话是不生效的,另外,此参数,只对select起作用,对DDL及UPDATE、delete操作不生效,例如: 1 2 3 4 5 6 mysql>setsession max_execution_time...
mysql> select/*+ set_var(max_execution_time=1000) */sleep(2)from t1 limit2; ERROR3024(HY000): Query execution was interrupted, maximum statement execution time exceeded 那如果把这条 select 语句封装在存储过程内部,按照手册上对参数 max_execution_time 的解释,则不生效。比如新建一个存储过程 sp_te...
MySQL 有一个参数叫 max_execution_time ,用来设置只读语句执行的超时时间,但是仅对单独执行的 select 语句有效;对于非单独执行的 select 语句,比如包含在存储过程、触发器等内置事务块里则不生效。官方手册上对这个参数解释如下: max_execution_timeapplies as follows: ...
mysql> select /*+ max_execution_time(1000) */ sleep(2) from t1 limit 2; ERROR 3024 (HY000): Query execution was interrupted, maximum statement execution time exceeded mysql> select /*+ set_var(max_execution_time=1000) */ sleep(2) from t1 limit 2; ERROR 3024 (HY000): Query execution...

原因：PHPMySQL执行超时。解决方法：重新正确执行来解决此问题。如下参考：1．例如，首先打开表c1中的add＿time字段的mysqlqueller。2．接下来，打开PHP编辑器并创建一个新的PHP文件，比如index。php，如下所示。3.在索引php，输入代码版本:$date = date(' y-m-d ');$conn = new mysqli (' ...
