MySQL創建Function時報的1418錯誤代號解決辦法

以下是引用片段：
ErrorCode:1418
ThisfunctionhasnoneofDETERMINISTIC,NOSQL,orREADSSQLDATAinitsdeclarationandbinaryloggingisenabled(you*might*wanttousethelesssafelog_bin_trust_function_creatorsvariable)-

　　解決方法如下：

　　1. mysql> SET GLOBAL log_bin_trust_function_creators = 1;

　　2. 系統啟動時 --log-bin-trust-function-creators=1

　　3. 在my.ini(linux下為my.conf)文件中 [mysqld] 標記后加一行內容為 log-bin-trust-function-creators

如果在create function的時候有 1418的錯語的時候:那么只需要執行set global log_bin_trust_routine_creators=1;

然后怎么create function 都不會有問題(當然,你的function必段正確哦),這是mysql的一個bug,搞不懂為什么,反正這樣做就OK了.

另外，也可以直接在配置文件my.cnf中添加如下行[mysqld] log_bin_trust_routine_creators=1;

這個命令可以在sql editor的環境中運行，并不需要重新啟動服務哦。

MySQL自5.0之後終於支援SP( Store Procedures )，
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) Assessment of the nature of a function is based on the “honesty” of the creator: MySQL does not check that a function declared DETERMINISTIC is free of statements that produce non-deterministic results.

To relax the preceding conditions on function creation (that you must have the SUPER privilege and that a function must be declared deterministic or to not modify data), set the global log_bin_trust_function_creators system variable to 1. By default, this variable has a value of 0, but you can change it like this:

mysql> SET GLOBAL log_bin_trust_function_creators = 1;
You can also set this variable by using the --log-bin-trust-function-creators=1 option when starting the server.
1. mysql> SET GLOBAL log_bin_trust_function_creators = 1;
2. 系統啟動時，加上--log-bin-trust-function-creators 參數為1
3. 直接在my.ini的[mysqld]區段加上log-bin-trust-function-creators=1
當然我想大多數人會用第三種方法，
ok...繼續我的SP學習,good luck..

二、mysql ERROR 1418 (HY000)

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)

應該是我們開啟了bin-log, 我們就必須指定我們的函數是否是
1 DETERMINISTIC 不確定的
2 NO SQL 沒有SQl語句，當然也不會修改數據
3 READS SQL DATA 只是讀取數據，當然也不會修改數據
4 MODIFIES SQL DATA 要修改數據
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指定一個參數。

我們可以通過設置如下的參數來關掉這個。

SET GLOBAL log_bin_trust_function_creators = 1;

(you *might* want to use the less safe log_bin_trust_function_creators
variable)
