建立存储过程时mysql
出错信息:sql
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)less
缘由:函数
这是咱们开启了bin-log, 咱们就必须指定咱们的函数是不是
1 DETERMINISTIC 不肯定的
2 NO SQL 没有SQl语句,固然也不会修改数据
3 READS SQL DATA 只是读取数据,固然也不会修改数据
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。若是咱们开启了 bin-log, 咱们就必须为咱们的function指定一个参数。code
解决方法:it
SQL codeio
mysql> show variables like 'log_bin_trust_function_creators';function
+---------------------------------+-------+配置
| Variable_name | Value |rust
+---------------------------------+-------+
| 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 |
+---------------------------------+-------+
这样添加了参数之后,若是mysqld重启,那个参数又会消失,所以记得在my.cnf配置文件中添加: log_bin_trust_function_creators=1
