Linux mysql数据库 MYSQL-Front连接SQL 执行错误#3167

提示：The 'INFORMATION_SCHEMA.SESSION_VARIABLES' feature is disabled; see the documentation for 'show_compatibility_56'

 

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

根据

mysql> select * from information_schema.global_status limit 3; 查询连接异常状态

ERROR 3167 (HY000): The 'INFORMATION_SCHEMA.GLOBAL_STATUS' feature is disabled; see the documentation for 'show_compatibility_56'

先登录MYSQL

根据show_compatibility_56 查询是否开启

...

LINUX命令如下

Jglz_test40:/bin # mysql -uroot -p
