sql-server - 如何联合存储过程中的两个查询以在一行中获得结果

Question

我有一个存储过程，我在其中加入了两个查询。我的查询是

alter PROCEDURE test

@SDate datetime,
@EDate datetime

作为

-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

-- Insert statements for procedure here
(Select count(quoteid) as TotalQuote, sum(totalamount) as QuoteAmount from dbo.QuoteBase
where CreatedOn BETWEEN @SDate AND @EDate) 
union All

(select  count(salesorderid)as TotalOrders, sum(totalamount) as OrderAmount from dbo.SalesOrderBase Where
CreatedOn BETWEEN @SDate AND @EDate)

我得到了列

Total Quote    Quote Amount
17                   700
118                 5000

但我想要这样的结果

Total Quote    Quote Amount    Total Orders   Order Amount
  17               700              118           5000

如果有人有想法请与我分享

试试这个——

ALTER PROCEDURE dbo.usp_test

      @SDate DATETIME 
    , @EDate DATETIME

AS BEGIN

    SET NOCOUNT ON;

    SELECT 
          t.TotalQuote
        , t.QuoteAmount
        , t2.TotalOrders
        , t2.OrderAmount
    FROM (SELECT a = 1) a
    CROSS JOIN (
        SELECT 
              TotalQuote = COUNT(quoteid)
            , QuoteAmount = SUM(totalamount)
        FROM dbo.QuoteBase
        WHERE CreatedOn BETWEEN @SDate AND @EDate
    ) t
    CROSS JOIN (
        SELECT 
              TotalOrders = COUNT(salesorderid)
            , OrderAmount = SUM(totalamount) 
        FROM dbo.SalesOrderBase
        WHERE CreatedOn BETWEEN @SDate AND @EDate
    ) t2

END

更新：

SELECT 
      t.TotalQuote
    , t.QuoteAmount
    , t2.TotalOrders
    , t2.OrderAmount
FROM (
    SELECT 
          TotalQuote = COUNT(quoteid)
        , QuoteAmount = SUM(totalamount)
    FROM dbo.QuoteBase
    WHERE CreatedOn BETWEEN @SDate AND @EDate
) t
FULL OUTER JOIN
(
    SELECT 
          TotalOrders = COUNT(salesorderid)
        , OrderAmount = SUM(totalamount) 
    FROM dbo.SalesOrderBase
    WHERE CreatedOn BETWEEN @SDate AND @EDate
) t2 ON 1 = 1

您可以使用 across join而不是 a union：

select  q1.TotalQuote
,       q1.QuoteAmount
,       q2.TotalOrders
,       q2.OrderAmount 
from    (
        ... first query ...
        ) q1
cross join
        (
        ... second query ...
        ) q2
