mysql 5.7 创建函数报错,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_creat
今天用命令创建函数,
报错
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)
原因是:
当二进制日志启用后,这个log_bin_trust_function_creators变量就会启用。它控制是否可以信任存储函数创建者,不会创建写入二进制日志引起不安全事件的存储函数。如果设置为0(默认值),用户不得创建或修改存储函数,除非它们具有除CREATE ROUTINE或ALTER ROUTINE特权之外的SUPER权限。 设置为0还强制使用DETERMINISTIC特性或READS SQL DATA或NO SQL特性声明函数的限制。 如果变量设置为1,MySQL不会对创建存储函数实施这些限制。 此变量也适用于触发器的创建
所以需要加一条命令
set global log_bin_trust_function_creators=TRUE; -- 设置,
delimiter ;;
CREATE FUNCTION concatFeatureJson(v_status tinyint, v_column_json VARCHAR(25)) RETURNS varchar(255)
begin
declare v_sql varchar(2000);
SELECT group_concat(concat('JSON_EXTRACT(',v_column_json,',','\'.$',feature_short_from_name,'\') ',feature_short_from_name))
into v_sql from feature_space where status = v_status ; RETURN v_sql;
end
