ERROR 1682 (HY000): Native table 'performance_schema'.'session_variables' has the wr

Posted 2020-12-01 hanglinux

mysql 5.6升级到mysql5.7查看参数报错

root@localhost [(none)]>show variables like ‘%data%‘;
ERROR 1682 (HY000): Native table ‘performance_schema‘.‘session_variables‘ has the wrong structure

 

--从mysql5.7.6开始information_schema.global_status已经开始被舍弃，为了兼容性，此时需要打开 show_compatibility_56 

 

解决办法

root@localhost [(none)]>set @@global.show_compatibility_56=ON;
Query OK, 0 rows affected (0.00 sec)

root@localhost [(none)]>show variables like ‘%data%‘;
