Question

我正在尝试连接一个字符串，以便我可以在in语句中使用它。我收到了一个错误：

“'='附近的语法不正确。”

我正在做什么？

DECLARE @Year uniqueidentifier = (SELECT TOP 1 y.des_zyearId FROM des_zyearset y WHERE y.des_YearText  = 2015)

--this is where I'm trying to concatenate

declare @heat varchar(70) = ('''' + (select top 1 fu.des_zfuelusagetypeId from des_zfuelusagetypeSet fu where = 'heat') + ', ' + (select top 1 fu.des_zfuelusagetypeId from des_zfuelusagetypeSet fu where = 'both') + '''')

Answer 1

declare @heat varchar(70) = 
('''' + (select top 1 fu.des_zfuelusagetypeId from des_zfuelusagetypeSet fu   
 where = 'heat' --->error here
)
 + ', ' + (select top 1 fu.des_zfuelusagetypeId from 
 des_zfuelusagetypeSet fu 
where = 'both'   --->error here
 ) + '''')

select语句中存在错误。您说的是where = 'heat'，它应该是where fu.somecolumn = 'heat'。同样，将其更改为第二个select

声明多个变量字符串以在IN语句中使用（'i'，'j'）
