第一次写MySQL FUNCTION,一直报错, Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '`company_id` int) RETURNS varchar(20) CHARSET utf8 BEGIN 本来的函数: CREATE DEFINER=`33323`@`%` FUNCTION `createSaleCode`(`benginStr` varchar,`company_id` int) RETURNS varchar(20) CHARSET utf8 BEGIN DECLARE nearnum VARCHAR(20); DECLARE nowdatepre VARCHAR(20); DECLARE numout VARCHAR(20); SELECT a.sale_code INTO nearnum FROM d_sale a WHERE a.company_id = company_id ORDER BY a.sale_id DESC limit 1; SELECT concat(extract(year_month from now()),LPAD(extract(day from now()), 2, 0)) INTO nowdatepre; IF locate(nowdatepre,nearnum)>0 THEN set numout = nearnum +1; ELSE set numout = concat(beginStr,nowdatepre,'00001'); END IF; RETURN numout; END 这段函数在Navicat上边执行不起来,在多次尝试之后将代码修改为以下: delimiter $$ CREATE DEFINER=`12212`@`%` FUNCTION createSaleCode(benginStr varchar(20),company_id int(11) ) RETURNS varchar(20) CHARSET utf8 BEGIN DECLARE nearnum VARCHAR(20); DECLARE nowdatepre VARCHAR(20); DECLARE numout VARCHAR(20); SELECT a.sale_code INTO nearnum FROM d_sale a WHERE a.company_id = company_id ORDER BY a.sale_id DESC limit 1; SELECT concat(extract(year_month from now()),LPAD(extract(day from now()), 2, 0)) INTO nowdatepre; IF locate(nowdatepre,nearnum)>0 THEN set numout = nearnum +1; ELSE set numout = concat(beginStr,nowdatepre,'00001'); END IF; RETURN numout; END$$ delimiter ; 问题解决。 默认情况下,delimiter是分号;。 总结 以上就是本文关于navicat不能创建函数解决方法分享的全部内容,希望对大家有所帮助。感兴趣的朋友可以继续参阅本站:简述Redis和MySQL的区别、MYSQL子查询和嵌套查询优化实例解析、几个比较重要的MySQL变量等,有什么问题可以随时留言,小编会及时回复大家的。感谢朋友们对本站的支持! |
