为什么我得到这个错误在'''附近预期条件的上下文中指定的非布尔类型的表达式？

Question

我已经做了很多次，没有发生错误，但这次很烦人。

错误：

了条件，预期的，在附近的上下文指定的非布尔类型的表达式“”。

Select aw.AppliedWorkID, aw.AppliedDateTime, aw.NIT_No, aw.Work_No, c.Name, c.CNIC, c.FatherName, w.WorkName, ISNULL(Withdrawn,0) as Withdrawn from AppliedWorks aw 
Inner Join Contractors c 
ON c.ContractorID= aw.Contractor_ID 
Inner Join Works w 
ON w.NIT_No= aw.NIT_No and w.WorkNo= aw.Work_No 
Where ISNULL(aw.Withdrawn,0)= 1 and aw.NIT_No= @NITNO and aw.Work_No= @WorkNo 
AND (datetime, w.OpeningDate, 106) +' '+ Convert(varchar(7), w.OpeningTime)) <= Convert(datetime, Getdate()) 

Answer 1

我觉得CONVERT在最后一行缺少

变化从

AND (datetime, w.OpeningDate, 106) +' '+ Convert(varchar(7), w.OpeningTime)) 
<= Convert(datetime, Getdate()) 

要

AND Convert(datetime, w.OpeningDate, 106) +' '+ Convert(varchar(7), w.OpeningTime)) 
<= Convert(datetime, Getdate())
