Sql 将查询与组合并

你好，我正在使用SQL Server，我想按分类合并数据 我有一个这样的问题

SELECT a.NamaMerk, b.NamaTipe from MsMerk as a inner join MsTipe  as b 
on a.ID_Merk = b.ID_Merk where a.FlagActive='Y' and b.FlagActive='Y' and a.ID_Merk = b.ID_Merk and b.ID_Tipe = b.ID_Tipe

这显示了数据

我想要这样的数据显示

SELECT a.NamaMerk, b.NamaTipe from MsMerk as a inner join MsTipe  as b 
on a.ID_Merk = b.ID_Merk where a.FlagActive='Y' and b.FlagActive='Y' and a.ID_Merk = b.ID_Merk and b.ID_Tipe = b.ID_Tipe

就像按类别合并数据一样，请帮助我感谢的

尝试一下。我使用row_number按namerk排序，当它大于1时，我将其设置为空字符串

    SELECT CASE 
         WHEN T.rank > 1 THEN '' 
         ELSE T.NamaMerk 
       END        AS 'NamaMerk', 
       T.NamaTipe AS 'NamaTipe' 
FROM   (SELECT a.NamaMerk, 
               b.NamaTipe, 
               Row_number() 
                 OVER( 
                   partition BY a.NamaMerk 
                   ORDER BY b.NamaTipe) AS 'RANK' 
        FROM   msmerk AS a 
               INNER JOIN mstipe AS b 
                       ON a.id_merk = b.id_merk 
        WHERE  a.flagactive = 'Y' 
               AND b.flagactive = 'Y' 
               AND a.id_merk = b.id_merk ) T

试试这个。我使用row_number按namerk排序，当它大于1时，我将其设置为空字符串

       T.NamaTipe AS 'NamaTipe' 
FROM   (SELECT a.NamaMerk, 
               b.NamaTipe, 
               Row_number() 
                 OVER( 
                   partition BY a.NamaMerk 
                   ORDER BY b.NamaTipe) AS 'RANK' 
        FROM   msmerk AS a 
               INNER JOIN mstipe AS b 
                       ON a.id_merk = b.id_merk 
        WHERE  a.flagactive = 'Y' 
               AND b.flagactive = 'Y' 
               AND a.id_merk = b.id_merk ) T

使用Row_Number，当它为1时，将NamaMerk和NamTipe else空间加上NamaTipe连接起来

我认为这些你可能必须在SSRS中进行，因为这与显示有关

因此，作为一个示例，您希望第二行三星值为空字符串？你为什么要这么做？了解可能有助于找到更好的解决方案。例如，您希望第二行的值为空字符串？你为什么要这么做？了解可能有助于找到更好的解决方案。只有使用单间距字体时，空格填充才能正常工作。不过这是一个很好的解决方案。只有在使用单间距字体时，用空格填充才能正常工作。然而，这是一个很好的解决方案。
