Mysqlfunction has none of DETERMINISTIC, NO SQL解决办法
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 ofDETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary loggingis enabled (you *might* want to use the less safe log_bin_trust_function_creatorsvariable)
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 variableslike'log_bin_trust_function_creators';
+---------------------------------+-------+
|Variable_name|Value|
+---------------------------------+-------+
|log_bin_trust_function_creators|OFF|
+---------------------------------+-------+
mysql>setglobal log_bin_trust_function_creators=1;
mysql>show variableslike'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
