This article introduces to friends how to open the bin-log log mysql error: This function has none of DETERMINISTIC, NO SQL solution,
When creating a stored procedure
Error message:
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)
Cause:
This is because we have opened the bin-log, we must specify whether our function is
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
In the function, there is only DETERMINISTIC , NO SQL and READS SQL DATA are supported. If we enable bin-log, we must specify a parameter for our function.
Solution:
SQL code 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 |
After adding the parameter in this way, if mysqld restarts, the parameter will disappear again, so remember to add:
log_bin_trust_function_creators=1
in the my.cnf configuration file Recommended: "mysql video tutorial"
