Question

嗨我有一个复杂的（我的SQL标准）计数，我需要在多个表上执行，我很乐意帮助。

我有三张桌子：

RELEASE

ID    |METADATA_ID|Is_Active|Creation_Source|Release_Status
123456|123        | Y       | A1            |Active
134567|124        | Y       | A1            |Active
145678|125        | N       | A2            |Closed

RELEASE_METADATA

ID     |UPC
123    |8001   
124    |8002
125    |8003

RELEASE_COUNTRY_RIGHT

(RELEASE)ID |COUNTRY_ID|MARKETING_RIGHT|OPT_OUT
123456      |   UK     |    N          |N    
123456      |   US     |    Y          |N   
123456      |   FR     |    Y          |Y    
134567      |   UK     |    Y          |N    
134567      |   US     |    Y          |Y   
145678      |   UK     |    Y          |Y    
145678      |   FR     |    Y          |N

我需要能够通过RELEASE的Source和Status过滤结果，包括来自RELEASE_METADATA的UPC，并计算RELEASE_COUNTRY_RIGHT中相关的行数，Marketing和Selected字段。

所以我的结果会是这样的：

ID    |Is_Active|Creation_Source|Release_Status|UPC |RELEASE_COUNTRY_RIGHT Rows|MARKETING_RIGHT|OPT_OUT    
123456| Y       |   A1          |Active        |8001| 3                        |  2            |  1  
134567| Y       |   A1          |Active        |8002| 2                        |  2            |  1

非常感谢任何帮助。

干杯！

更新：我尝试过使用下面的SHALAKA解决方案，但是在替换下表所示的表和字段名称之后我遇到了麻烦。我已经更新了上面的表格和字段名称，因为我意识到我所拥有的可能会产生误导。还有一个额外的字段，我错过了，因为连接不像我预期的那样。 RELEASE通过release.ID = release_metadata_id与RELEASE_METADATA连接，第三个表需要通过release.ID = release_country_right.release_ID加入。

这是我的尝试：

SELECT grp_1.*, COUNT(a5.OPT_OUT) OPT_OUT
      FROM (SELECT grp.*, COUNT(a4.MARKETING_RIGHT) MARKETING_RIGHT
              FROM (SELECT a1.id,
                           a1.IS_ACTIVE,
                           a1.CREATION_SOURCE,
                           a1.RELEASE_STATUS,
                           a2.upc,
                           COUNT(a3.RELEASE_ID) a_row
                      FROM dschd.release a1, dschd.release_metadata a2, DSCHD.RELEASE_COUNTRY_RIGHT a3
                     WHERE a1.RELEASE_METADATA_ID = a2.id
                       AND a1.id = a3.RELEASE_ID
                       AND a1.IS_ACTIVE = 'Y'
                     GROUP BY a1.id, a1.IS_ACTIVE, a1.CREATION_SOURCE, a1.RELEASE_STATUS, a2.UPC) grp,
                   DSCHD.RELEASE_COUNTRY_RIGHT a4
             WHERE a4.OPT_OUT = grp.id
               AND a4.MARKETING_RIGHT = 'N'
             GROUP BY grp.id,
                      grp.IS_ACTIVE,
                      grp.CREATION_SOURCE,
                      grp.RELEASE_STATUS,
                      grp.upc,
                      grp.a_row) grp_1,
           DSCHD.RELEASE_COUNTRY_RIGHT a5
     WHERE a5.RELEASE_ID = grp_1.id
       AND a5.OPT_OUT = 'Y'
     GROUP BY grp_1.id,
              grp_1.IS_ACTIVE,
              grp_1.CREATION_SOURCE,
              grp_1.RELEASE_STATUS,
              grp_1.upc,
              grp_1.a_row,
              grp_1.MARKETING_RIGHT

Answer 1

SELECT grp_1.*, COUNT(a5.selected) selected
  FROM (SELECT grp.*, COUNT(a4.marketing) marketing
          FROM (SELECT a1.id,
                       a1.active,
                       a1.source,
                       a1.status,
                       a2.ref,
                       COUNT(a3.id) a_row
                  FROM data1 a1, data2 a2, data3 a3
                 WHERE a1.id = a2.id
                   AND a2.id = a3.id
                   AND a1.active = 'Y'
                 GROUP BY a1.id, a1.active, a1.source, a1.status, a2.ref) grp,

          grp_1.ref,
          grp_1.a_row,
          grp_1.marketing
