MySQL创建方法异常:This function has none of DETERMINISTIC, NO SQL
MySQL创建方法错误:This function has none of DETERMINISTIC, NO SQL创建function时出错信息：ERROR 1418
MySQL创建方法错误:This function has none of DETERMINISTIC, NO SQL
创建function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 '%func%';+---------------------------------+-------+| Variable_name?????????????????? | Value |+---------------------------------+-------+| log_bin_trust_function_creators | OFF?? |+---------------------------------+-------+1 row in set (0.00 sec)mysql> set global log_bin_trust_function_creators=1;Query OK, 0 rows affected (0.00 sec)mysql> show variables like '%func%';+---------------------------------+-------+| Variable_name?????????????????? | Value |+---------------------------------+-------+| log_bin_trust_function_creators | ON??? |+---------------------------------+-------+1 row in set (0.00 sec) mysql>
