sql插入子查詢

Question

我想運行此查詢

INSERT INTO [tblPollLogs]
           ([lastModified]
           ,[ip]
           ,[a1]
           ,[a2]
         )
     VALUES
           (getdate()
           ,'aaa'
           ,(select top 1 header from [tblPollAnswer] where [pollAnswerId] = @param1)
           ,(select top  1 header from [tblPollAnswer] where [pollAnswerId] = @param2)         
         )

但是我得到了錯誤

在這種情況下，不允許子查詢。 僅允許標量表達式。

我可以在一個查詢中運行此查詢還是我需要在運行此查詢之前獲取值

謝謝

嘗試將其更改為insert...select如下insert...select

INSERT INTO [tblPollLogs]
           ([lastModified]
           ,[ip]
           ,[a1]
           ,[a2]
         )
select getdate(),
       'aaa',
      (select top 1 header from [tblPollAnswer] where [pollAnswerId] = @param1),
      (select top  1 header from [tblPollAnswer] where [pollAnswerId] = @param2)
