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

mysql 5.6升級到mysql5.7查看參數報錯

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

 

--從mysql5.7.6開始information_schema.global_status已經開始被舍棄，為了兼容性，此時需要打開 show_compatibility_56 

 

解決辦法

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

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