获取错误“ERROR 1064（42000）：您的SQL语法出错;请查看与您的MySQL服务器版本对应的手册，以便在正确的语法附近使用'）”

我在编码中找不到任何错误的语法，但仍然无法找到问题，

CREATE PROCEDURE sp_GetAssignTask(IN module varchar(100),IN did int,IN actstatus int,IN  act varchar(30),IN sdate datetime,IN edate datetime,OUT outmsg varchar(20))
BEGIN
DECLARE DateDuration int;
SET DateDuration = SELECT DATEDIFF(edate, sdate) ;
insert into sch_taskassigned   (Duration,Module,Content,Deptid,taskenddate,taskstartdate,activestatus,activity,subactivity)values (DateDuration,modul,conte,did,edate,sdate,actstatus,act,subact);
set outmsg = 'Added Successfully';
END

Answer 1

我能看到的唯一语法问题是

SET DateDuration = (SELECT DATEDIFF(edate, sdate));通知我在等于之后添加了（）。

另外，根据您执行此操作的客户端，您可能需要更改分隔符，例如：

DELIMITER $$

CREATE PROCEDURE sp_GetAssignTask(IN module varchar(100),IN did int,IN actstatus int,IN  act varchar(30),IN sdate datetime,IN edate datetime,OUT outmsg varchar(20))
BEGIN
DECLARE DateDuration int;
SET DateDuration = (SELECT DATEDIFF(edate, sdate));
insert into sch_taskassigned   (Duration,Module,Content,Deptid,taskenddate,taskstartdate,activestatus,activity,subactivity)values (DateDuration,modul,conte,did,edate,sdate,actstatus,act,subact);
set outmsg = 'Added Successfully';
END

$$
