本文实例讲述了mysql设置触发器权限的方法,针对权限错误的情况非常实用。具体分析如下:
mysql导入数据提示没有super privilege权限处理,如下所示:
1 error 1419 (hy000): you do not have the super privilege and binary logging is enabled
导入function 、 trigger 到 mysql database,报错:
1 you do not have the super privilege and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable)”.
原因:
function / trigger 中有dangerous statements修改数据库,错误只在启用binary logging选项进行主从复制的服务器上出现。
解决方法如下:
1)导入数据的用户不仅需要create routine, alter routine, create trigger, alter trigger, create function 和 alter function 权限,还需要super privileges 权限,使用超级用户导入数据。
2)让所有用户具有执行类似functions的权限,危险,不推荐,
123 o by specifying it on the server start, like: –log-bin-trust-function-creators=1 o by setting it to 1 through the set global statement, like: mysql> set global log_bin_trust_function_creators = 1;
3)如果不需要复制,或者是从库,关闭binlog,
1234 # binary logging – not required for slaves, but recommended #log-bin=mysql-bin # binary logging format – mixed recommended #binlog_format=mixed
希望本文所述对大家的mysql数据库设计有所帮助。
