MySQL建立函數出現1418錯誤解決辦法總結

代碼如下:

錯誤碼: 1418
This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable) 這個是建立函數功能未開。

(you *might* want to use the less safe log_bin_trust_function_creators variable)
(0 ms taken)

分析：

根據系統提示，導致該錯誤的原因可能是一個安全設定方面的配置，查手冊

log_bin_trust_function_creators參數預設0，是不允許function的同步的，一般我們在配置repliaction的時候，都忘記關注這個參數，這樣在master更新funtion後，slave就會報告錯誤，然後slave stoped。

處理過程：

登陸mysql資料庫

> set global log_bin_trust_function_creators ＝ 1;
> start slave;

mysql> set og_bin_trust_function_creators =1;
ERROR 1193 (HY000): Unknown system variable 'og_bin_trust_function_creators'
mysql> set log_bin_trust_function_creators =1;
ERROR 1229 (HY000): Variable 'log_bin_trust_function_creators' is a GLOBAL variable and should be set with SET GLOBAL
mysql> set global log_bin_trust_function_creators =1;
Query OK, 0 rows affected (0.00 sec)

mysql> show variable like '%func%';
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'variable like '%func%'' at line 1
mysql> show variables like '%func%';

跟蹤mysql的開機記錄，slave正常運行，問題解決。
