Question

我正在尝试使用Case语句将行转换为列，并且可以，但是我有重复的ID。

000001  NULL    NULL    NULL    12075000.000    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL
000001  NULL    NULL    NULL    NULL    10500000.000    NULL    NULL    NULL    NULL    NULL    NULL    NULL
000001  NULL    NULL    NULL    NULL    NULL    10500000.000    NULL    NULL    NULL    NULL    NULL    NULL
000001  NULL    NULL    NULL    NULL    NULL    NULL    10500000.000    NULL    NULL    NULL    NULL    NULL
000001  NULL    NULL    NULL    NULL    NULL    NULL    NULL    10500000.000    NULL    NULL    NULL    NULL
000001  NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    10500000.000    NULL    NULL    NULL

第一列是id列，其他列代表月份。如您所见，id是相同的。有没有一种方法可以显示所有12个月内每个ID的数据在一行中？

SELECT CID,
    (CASE WHEN EOMDATE = '2018-08-16' THEN BALANCE end) AS SHRAWAN,
    (CASE WHEN EOMDATE = '2018-09-16' THEN BALANCE end) AS BHADAU,
    (CASE WHEN EOMDATE = '2018-10-17' THEN BALANCE end) AS ASHOJ,
    (CASE WHEN EOMDATE = '2018-11-16' THEN BALANCE end) AS KARTIK,
    (CASE WHEN EOMDATE = '2018-12-15' THEN BALANCE end) AS MANGSHIR,
    (CASE WHEN EOMDATE = '2019-01-14' THEN BALANCE end) AS POUSH,
    (CASE WHEN EOMDATE = '2019-02-12' THEN BALANCE end) AS MAGH,
    (CASE WHEN EOMDATE = '2019-03-14' THEN BALANCE end) AS FALGUN,
    (CASE WHEN EOMDATE = '2019-04-13' THEN BALANCE end) AS CHAITRA,
    (CASE WHEN EOMDATE = '2019-05-14' THEN BALANCE end) AS BAISHAKH,
    (CASE WHEN EOMDATE = '2019-06-16' THEN BALANCE end) AS JETH,
    (CASE WHEN EOMDATE = '2019-07-17' THEN BALANCE end) AS ASHAD
    FROM 
    (SELECT R.BR, R.CID, E.EOMDate, SUM(E.BALANCEAMT) AS BALANCE
    FROM T_EOMHIST E 
        LEFT JOIN T_RELACC R ON E.Acc = R.Acc AND E.BR = R.BR AND E.APPTYPE IN ('1','3')
        LEFT JOIN T_GLLINK G ON G.BR = E.BR AND G.Code = E.GlCode AND G.CoopRep01 = 'Y' and G.TableId in ('10','30')
        LEFT JOIN T_GLCONTROL H ON H.BR = E.BR 
    WHERE H.FinYear = '2018' AND E.EOMDate BETWEEN H.FinYrStartDate AND H.FinYrEndDate 
        AND R.TYPE = '010' AND R.AppType IN ('1','3') 
        AND CID = '000001'
        GROUP BY R.BR, R.CID, E.EOMDATE)T 
    WHERE CID = '000001'

这是选择查询的代码。

预期结果是同一列的单行记录。如果仅没有任何数据，请显示NULL。我也尝试过使用GROUP BY子句，但是它在显示聚合函数时显示了一些错误。

Answer 1

SELECT CID,
    SUM(ISNULL(CASE WHEN EOMDATE = '2018-08-16' THEN BALANCE end, 0)) AS SHRAWAN,
    SUM(ISNULL(CASE WHEN EOMDATE = '2018-09-16' THEN BALANCE end, 0)) AS BHADAU,
    SUM(ISNULL(CASE WHEN EOMDATE = '2018-10-17' THEN BALANCE end, 0)) AS ASHOJ,
    SUM(ISNULL(CASE WHEN EOMDATE = '2018-11-16' THEN BALANCE end, 0)) AS KARTIK,
    SUM(ISNULL(CASE WHEN EOMDATE = '2018-12-15' THEN BALANCE end, 0)) AS MANGSHIR,
    SUM(ISNULL(CASE WHEN EOMDATE = '2019-01-14' THEN BALANCE end, 0)) AS POUSH,
    SUM(ISNULL(CASE WHEN EOMDATE = '2019-02-12' THEN BALANCE end, 0)) AS MAGH,
    SUM(ISNULL(CASE WHEN EOMDATE = '2019-03-14' THEN BALANCE end, 0)) AS FALGUN,
    SUM(ISNULL(CASE WHEN EOMDATE = '2019-04-13' THEN BALANCE end, 0)) AS CHAITRA,
    SUM(ISNULL(CASE WHEN EOMDATE = '2019-05-14' THEN BALANCE end, 0)) AS BAISHAKH,
    SUM(ISNULL(CASE WHEN EOMDATE = '2019-06-16' THEN BALANCE end, 0)) AS JETH,
    SUM(ISNULL(CASE WHEN EOMDATE = '2019-07-17' THEN BALANCE end, 0)) AS ASHAD
FROM FROM 
    ...
GROUP BY CID

或者，如果您需要NULL而不是0：

NULLIF(SUM(ISNULL(CASE WHEN EOMDATE = '2018-08-16' THEN BALANCE end, 0)), 0) AS SHRAWAN

Answer 2

尝试这样：

   SELECT CID, 
    sum(isnull(SHRAWAN, 0)) AS SHRAWAN,
        sum(isnull(BHADAU, 0)) AS BHADAU,
        sum(isnull(ASHOJ, 0)) AS ASHOJ,
        sum(isnull(KARTIK, 0)) AS KARTIK,
        sum(isnull(MANGSHIR, 0)) AS MANGSHIR,
        sum(isnull(POUSH, 0)) AS POUSH,
        sum(isnull(MAGH, 0)) AS MAGH,
        sum(isnull(FALGUN, 0)) AS FALGUN,
        sum(isnull(CHAITRA, 0)) AS CHAITRA,
        sum(isnull(BAISHAKH, 0)) AS BAISHAKH,
        sum(isnull(JETH, 0)) AS JETH,
        sum(isnull(ASHAD, 0)) AS ASHAD    
        from (
    SELECT CID,
        (CASE WHEN EOMDATE = '2018-08-16' THEN BALANCE end) AS SHRAWAN,
        (CASE WHEN EOMDATE = '2018-09-16' THEN BALANCE end) AS BHADAU,
        (CASE WHEN EOMDATE = '2018-10-17' THEN BALANCE end) AS ASHOJ,
        (CASE WHEN EOMDATE = '2018-11-16' THEN BALANCE end) AS KARTIK,
        (CASE WHEN EOMDATE = '2018-12-15' THEN BALANCE end) AS MANGSHIR,
        (CASE WHEN EOMDATE = '2019-01-14' THEN BALANCE end) AS POUSH,
        (CASE WHEN EOMDATE = '2019-02-12' THEN BALANCE end) AS MAGH,
        (CASE WHEN EOMDATE = '2019-03-14' THEN BALANCE end) AS FALGUN,
        (CASE WHEN EOMDATE = '2019-04-13' THEN BALANCE end) AS CHAITRA,
        (CASE WHEN EOMDATE = '2019-05-14' THEN BALANCE end) AS BAISHAKH,
        (CASE WHEN EOMDATE = '2019-06-16' THEN BALANCE end) AS JETH,
        (CASE WHEN EOMDATE = '2019-07-17' THEN BALANCE end) AS ASHAD
        FROM 
        (SELECT R.BR, R.CID, E.EOMDate, SUM(E.BALANCEAMT) AS BALANCE
        FROM T_EOMHIST E 
            LEFT JOIN T_RELACC R ON E.Acc = R.Acc AND E.BR = R.BR AND E.APPTYPE IN ('1','3')
            LEFT JOIN T_GLLINK G ON G.BR = E.BR AND G.Code = E.GlCode AND G.CoopRep01 = 'Y' and G.TableId in ('10','30')
            LEFT JOIN T_GLCONTROL H ON H.BR = E.BR 
        WHERE H.FinYear = '2018' AND E.EOMDate BETWEEN H.FinYrStartDate AND H.FinYrEndDate 
            AND R.TYPE = '010' AND R.AppType IN ('1','3') 
            AND CID = '000001'
            GROUP BY R.BR, R.CID, E.EOMDATE)T 
        WHERE CID = '000001'
        ) as t
        group by t.CID

如何修复“将来自同一ID的所有数据合并为一行”？
