Mysql establishes a custom function problem _mysql

The problem occurs immediately when you create a function:

ERROR 1418 (HY000): This routine has none of deterministic, NO SQL,
Or reads SQL DATA in it declaration and binary logging is enabled
(You *might* want to use the less safe log_bin_trust_routine_creators
Variable
Find the solution in the MySQL online documentation:
Http://dev.mysql.com/doc/refman/5.1/zh/stored-procedures.html#create-procedure
You only need to set the log_bin_trust_routine_creators to 1, and the workaround

Add Log-bin-trust-function-creators=1 to My.ini's [mysqld]
I hope that you encounter problems in the use of less detours.
