MySql创建函数问题

今天在整理数据时，又碰到MySQL函数不能创建的问题，以前也遇到过多次，解决是解决了，但是解决办法总是记不住，也没有很好地写下来，以至于每次都要再次Google，耗时耗力，这次终于受不了了，还是选择写出来：

出错信息大致类似：

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)

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)

建立不了函数，是未开启功能：

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
   >
    

  

  

    
  

  

   搞定！
