mysql8.0错误代码:1418This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declarati

1 queries executed, 0 success, 1 errors, 0 warnings

查询：CREATE FUNCTION test() RETURNS INT BEGIN DECLARE v_num INT default 0; SELECT COUNT(*) INTO v_num FROM admin; RETURN v_num; END

错误代码： 1418
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)

解决方法:
在MySQL中执行如下代码：

set global log_bin_trust_function_creators=TRUE;
