sql插入子查询

Question

I want to run this query

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)         
         )

But I get the error

Subqueries are not allowed in this context. Only scalar expressions are allowed.

can i run this query in one query or i need get the values before running this query

thanks

Try to change it to insert...select as below

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)
