本篇文章给大家介绍一下mysql 报错This function has none of DETERMINISTIC解决方案。有一定的参考价值,有需要的朋友可以参考一下,希望对大家有所帮助。
本文向朋友们介绍开启bin-log日志mysql报错:This function has none of DETERMINISTIC, NO SQL解决办法,
创建存储过程时
出错信息:
ERROR 1418 (HY000): 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)
原因:
这是我们开启了bin-log, 我们就必须指定我们的函数是否是
1 DETERMINISTIC 不确定的 2 NO SQL 没有SQl语句,当然也不会修改数据 3 READS SQL DATA 只是读取数据,当然也不会修改数据 4 MODIFIES SQL DATA 要修改数据 5 CONTAINS SQL 包含了SQL语句
其中在function里面,只有 DETERMINISTIC, NO SQL 和 READS SQL DATA 被支持。如果我们开启了 bin-log, 我们就必须为我们的function指定一个参数。
解决方法:
SQL code mysql> show variables like 'log_bin_trust_function_creators'; +---------------------------------+-------+ | Variable_name | Value | +---------------------------------+-------+ | log_bin_trust_function_creators | OFF | +---------------------------------+-------+ mysql> set global log_bin_trust_function_creators=1; mysql> show variables like 'log_bin_trust_function_creators'; +---------------------------------+-------+ | Variable_name | Value | +---------------------------------+-------+ | log_bin_trust_function_creators | ON |
这样添加了参数以后,如果mysqld重启,那个参数又会消失,因此记得在my.cnf配置文件中添加:
log_bin_trust_function_creators=1
