mysql存储过程语法错误:

Question

我有一个 mysql 存储过程，它给了我以下错误:-

#1064 - 您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，了解在第 4 行的 'set intoffer = 'select max(offerid) from home' if(intoffer IS NULL) then set int' 附近使用的正确语法

我已将分隔符框中的分隔符设置为;。存储过程是

create procedure sp()
begin
declare intoffer int
set intoffer = 'select max(offerid) from home'
if(intoffer IS NULL) then
set intoffer=1
else
set intoffer=intoffer+1
insert into home(offerid,offerheader,offertext,offerimage,offerlink) values(intoffer,'d','d','d','d')
end;

Answer 1

存在一些语法和其他错误。试试这个代码 -

CREATE PROCEDURE sp()
BEGIN
  DECLARE intoffer INT;

  SELECT max(offerid) INTO intoffer FROM home;
  IF (intoffer IS NULL) THEN
    SET intoffer = 1;
  ELSE
    SET intoffer = intoffer + 1;
  END IF;
  INSERT INTO home (offerid, offerheader, offertext, offerimage, offerlink) VALUES (intoffer, 'd', 'd', 'd', 'd');
END
