子查询没有引入EXISTS时，只能在选择列表中指定一个表达式。 Sql Server 2008

我遇到了下面提到的sql查询的问题。基本上我试图列出所有在当前周和前一周每天捕获数据的系统用户。子查询没有引入EXISTS时，只能在选择列表中指定一个表达式。 Sql Server 2008

问题与我的查询下面我得到“只有一个表达式可以在选择列表中指定子查询未与EXISTS引入 ”。我已经改变了这个查询的一部分来使用EXISTS，但在子查询的最后一行仍然得到相同的错误。

DECLARE @Dates date; 
SET @Dates = '20091012'; 
DECLARE @FirstDayOfWeek date; 
DECLARE @lastDayOfWeek date; 

SET @FirstDayOfWeek = dbo.[fn_GetFirstDayOfWeek](@Dates); 
SET @lastDayOfWeek = DATEADD(day, 6,@FirstDayOfWeek); 

SET NOCOUNT ON 
SELECT DISTINCT q.CapturerId, u.Firstname, u.Lastname INTO #Users 
from Wop_Questionnaires q JOIN 
     Frwk_Users u 
    ON 
     q.CapturerId = u.Id JOIN 
    Core_Areas a ON 
    u.X_Wop_ProvinceId = a.Id 

WHERE u.X_Wop_ProvinceId = 5 



SELECT (SELECT #Users.Firstname+' '+#Users.Lastname, COUNT(q.CapturerId) 
    from Wop_Questionnaires q JOIN #Users on q.CapturerId = #Users.CapturerId 
    where EXISTS(SELECT #Users.CapturerID from #Users WHERE q.CapturerId = #Users.CapturerId) 
    AND q.CaptureDate >=DATEADD(DAY,DATEDIFF(DAY,'19000101',@FirstDayOfWeek),'19000101') 
    And q.CaptureDate < DATEADD(DAY,DATEDIFF(DAY,'19000101',@FirstDayOfWeek)+1,'19000101') 
    GROUP BY q.CapturerId, #Users.Firstname,#Users.Lastname) Sun, 
(SELECT #Users.Firstname+' '+#Users.Lastname, COUNT(q.CapturerId) 
    from Wop_Questionnaires q JOIN #Users on q.CapturerId = #Users.CapturerId

    AND q.CaptureDate >=DATEADD(DAY,DATEDIFF(DAY,'19000101',DATEADD(DAY,1,@FirstDayOfWeek)),'19000101') 
    AND q.CaptureDate < DATEADD(DAY,DATEDIFF(DAY,'19000101',DATEADD(DAY,1,@FirstDayOfWeek))+1,'19000101')

转换为以下？

SELECT... GROUP BY Sun 
UNION 
SELECT... GROUP BY Mon 
UNION 
SELECT ... GROUP BY Tue

可能不是最有效的答案，但应该做的工作。

感谢您的建议，但我实际上需要让用户每日总计在一行中。我需要计算某个地区的用户每日所做的每日Sun - Sat的条目，每个用户都列在一行中。已经尝试了几个角度，但仍然挣扎谢谢 – Tebogo 2010-02-08 15:51:16

啊，抱歉误读您的查询 – Paolo 2010-02-08 17:06:32

修改了我的sql，看起来像下面这样：可能有更干净和有效的方法来做到这一点。我正在使用枢轴来达到预期的效果。

打扰长码。

子查询没有引入EXISTS时，只能在选择列表中指定一个表达式。 Sql Server 2008
