储存过程怎么让一条带有变量的SQL语句在变量前后加单引号
ALTER PROCEDURE [dbo].[proc_business]
@user varchar(20),
@city varchar(20),
AS
BEGIN
declare @wheretrue varchar(100)
if(@city='') set @wheretrue='select DEPT_CODE from T_USERDEPT where USER_NO='+@user+''
else set @wheretrue ='select DEPT_CODE from T_DEPT where BRANCH_CODE='+@city+''
select * from P_BUSINESS_LIST where DEPT_CODE in (@wheretrue)
END
我是想根据@city这个参数有没有值来产生不同的条件，条件是产生了
select DEPT_CODE from T_DEPT where BRANCH_CODE=HGZL002
可是BRANCH_CODE，USER_NO这两个字段是varchar类型的，所以产生出来的SQL因为少了两个单引号怎么也查不到值。

双引号外面套单引号 '"+xxxxx+"'
