Question

我正在寻找我的SQL问题的解决方案，我必须连续显示具有适当标题的财务期间的三个总计，到目前为止，我已显示所有信息，但它在使用union的列中。我不知道在哪里放置连接或哪种类型更适合，我真的很感激这个答案的帮助，因为我已经看了一段时间。

SELECT 
    (SELECT SUM(ComStatinYearTotal) 
     FROM tblComStatInYear 
     WHERE ComStatinYearYear = '2014' 
       AND ComStatInYearWeekEnd > '2014-07-01'
       AND ComStatInYearWeekEnd < '2014-09-30'
       AND ComStatInYearCltCode = 'STI02')
    - (SELECT SUM(ComStatinYearTotal)
       FROM tblComStatInYear 
       WHERE ComStatinYearYear = '2013' 
         AND ComStatInYearWeekEnd > '2013-07-01'
         AND ComStatInYearWeekEnd < '2013-09-30' 
         AND ComStatInYearCltCode = 'STI02') TotalDiff  

UNION

SELECT 
   (SELECT SUM(ComStatinYearPen) 
    FROM tblComStatInYear 
    WHERE ComStatinYearYear = '2014' 
      AND ComStatInYearWeekEnd > '2014-07-01'
      AND ComStatInYearWeekEnd < '2014-09-30' 
      AND ComStatInYearCltCode = 'STI02')
    - (SELECT SUM(ComStatinYearPen)
       FROM tblComStatInYear 
       WHERE ComStatinYearYear = '2013' 
         AND ComStatInYearWeekEnd > '2013-07-01'
         AND ComStatInYearWeekEnd < '2013-09-30' 
         AND ComStatInYearCltCode = 'STI02') PenDiff 

UNION

SELECT 
   (SELECT SUM(ComStatinYearPrin) 
    FROM tblComStatInYear 
    WHERE ComStatinYearYear = '2014' 
      AND ComStatInYearWeekEnd > '2014-07-01'
      AND ComStatInYearWeekEnd < '2014-09-30' 
      AND ComStatInYearCltCode = 'STI02')
   - (SELECT SUM(ComStatInYearPrin)
      FROM tblComStatInYear 
      WHERE ComStatinYearYear = '2013' 
        AND ComStatInYearWeekEnd > '2013-07-01'
        AND ComStatInYearWeekEnd < '2013-09-30' 
        AND ComStatInYearCltCode = 'STI02') PrinDiff

Answer 1

解决问题的最简单方法是使用子查询：

select
  (select sum(x) from table1) as result1,
  (select sum(y) from table2) as result2,
  (select sum(z) from table3) as result3

Answer 2

我对您的数据了解不多，但您可以执行以下操作：

DECLARE @year2014(ComStatinYearTotal_SUM INT, ComStatinYearPen_SUM INT, ComStatinYearPrin_SUM INT)
DECLARE @year2013(ComStatinYearTotal_SUM INT, ComStatinYearPen_SUM INT, ComStatinYearPrin_SUM INT)
INSERT INTO @year2014
SELECT SUM(ComStatinYearTotal), SUM(ComStatinYearPen), SUM(ComStatinYearPrin)
FROM tblComStatInYear 
    WHERE ComStatinYearYear = '2014' 
    AND ComStatInYearWeekEnd > '2014-07-01'
    AND ComStatInYearWeekEnd < '2014-09-30'
    AND ComStatInYearCltCode = 'STI02';

INSERT INTO @year2013
SELECT SUM(ComStatinYearTotal), SUM(ComStatinYearPen), SUM(ComStatinYearPrin)
FROM tblComStatInYear 
WHERE ComStatinYearYear = '2013' 
    AND ComStatInYearWeekEnd > '2013-07-01'
    AND ComStatInYearWeekEnd < '2013-09-30' 
    AND ComStatInYearCltCode = 'STI02';

SELECT t1.ComStatinYearTotal_SUM-t2.ComStatinYearTotal_SUM INT, t1.ComStatinYearPen_SUM - t2.ComStatinYearPen_SUM INT, t1.ComStatinYearPrin_SUM - t2.ComStatinYearPrin_SUM
FROM @year2014 t1, @year2013 t2;

插图：

-- Declare TABLE variables
DECLARE @T1 TABLE (C1 INT, C2 INT, C3 INT);
DECLARE @T2 TABLE (C1 INT, C2 INT, C3 INT);

--Load values
INSERT INTO @T1 VALUES (100, 200, 300);
INSERT INTO @T2 VALUES (10, 20, 30);

-- Apply the Subtract
SELECT T1.C1-T2.C1, T1.C2-T2.C2, T1.C3-T2.C3
FROM @T1 T1, @T2 T2

连接三个表sql条件
