mysql 使用過程當中出現問題

1. mysql_front鏈接報錯，sql執行錯誤#3167的解決方案

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

--從mysql5.7.6開始information_schema.global_status已經開始被捨棄，爲了兼容性，此時須要打開 show_compatibility_56
MySQL> select * from information_schema.global_status limit 3;
ERROR 3167 (HY000): The 'INFORMATION_SCHEMA.GLOBAL_STATUS' feature is disabled; see the documentation for 'show_compatibility_56'

--查看show_compatibility_56其值
mysql> show variables like '%show_compatibility_56%';
+-----------------------+-------+
| Variable_name         | Value |
+-----------------------+-------+
| show_compatibility_56 | OFF   |
+-----------------------+-------+
1 row in set (0.01 sec)


--把show_compatibility_56打開
mysql> set global show_compatibility_56=on;
Query OK, 0 rows affected (0.00 sec)


mysql> show variables like '%show_compatibility_56%';
+-----------------------+-------+
| Variable_name         | Value |
+-----------------------+-------+
| show_compatibility_56 | ON    |
+-----------------------+-------+
1 row in set (0.00 sec)


mysql> select * from information_schema.global_status limit 3;
+-----------------------+----------------+
| VARIABLE_NAME         | VARIABLE_VALUE |
+-----------------------+----------------+
| ABORTED_CLIENTS       | 0              |
| ABORTED_CONNECTS      | 0              |
| BINLOG_CACHE_DISK_USE | 0              |
+-----------------------+----------------+
3 rows in set, 1 warning (0.00 sec)

完成上述操做後，便可用mysql_front鏈接到mysql數據庫了，能夠對數據庫進行圖形化的界面操做~
