創(chuàng)建存儲(chǔ)過程時(shí)

出錯(cuò)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：

這是我們開啟了bin-log, 我們就必須指定我們的函數(shù)是否是
1 DETERMINISTIC 不確定的
2 NO SQL 沒有SQl語句，當(dāng)然也不會(huì)修改數(shù)據(jù)
3 READS SQL DATA 只是讀取數(shù)據(jù)，當(dāng)然也不會(huì)修改數(shù)據(jù)
4 MODIFIES SQL DATA 要修改數(shù)據(jù)
5 CONTAINS SQL 包含了SQL語句

其中在function里面，只有 DETERMINISTIC, NO SQL 和 READS SQL DATA 被支持。如果我們開啟了 bin-log, 我們就必須為我們的function指定一個(gè)參數(shù)。

解決方法：

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 |

+---------------------------------+-------+

這樣添加了參數(shù)以后，如果mysqld重啟，那個(gè)參數(shù)又會(huì)消失，因此記得在my.cnf配置文件中添加：
log_bin_trust_function_creators=1
