Sql 一个唯一ID的共同申请人姓名和地址从多行到多列

这就是问题所在

SELECT b.ID, e.customername AS "Applicant name",
       f.address AS "Applicant address",
       x.customername AS "Co-Applicant name",
       x.address AS "Co-Applicant address"
  FROM table_1 b,
       table_2 e,
       table_3 f,
       (SELECT b.customername, g.agreementid, a.address
          FROM table_2 g, table_4 x, table_2 b, table_3 a
         WHERE g.ID = x.ID
           AND b.customerid = x.custid
           AND b.customerid = a.custid
           AND x.flag <> 'G') x
 WHERE b.custid = e.customerid
   AND f.custid = b.lesseeid
   AND f.bptype = 'LS'
   AND f.mailingaddress = 'Y'
   AND b.ID = x.ID
   AND b.ID='101'  

我需要以下格式的数据

我想您可以先进行条件聚合，然后使用表-

WITH DATAA AS (SELECT 101 ID, 'aamir' name, 'address1' address, 'rahul' co_applicant, 'london' co_address FROM DUAL
               UNION ALL
               SELECT 101, 'aamir', 'address1', 'vijay', 'Paris' FROM DUAL
               UNION ALL
               SELECT 101, 'aamir', 'address1', 'sanjay', 'New York' FROM DUAL
               ),
     TEMP AS (select D.*, ROW_NUMBER() OVER(PARTITION BY name ORDER BY co_applicant) RN from DATAA D)
SELECT ID, NAME, ADDRESS
      ,MAX(CASE WHEN RN = 1 THEN CO_APPLICANT ELSE NULL END) AS name_1
      ,MAX(CASE WHEN RN = 1 THEN CO_ADDRESS   ELSE NULL END) AS ADDRESS_1
      ,MAX(CASE WHEN RN = 2 THEN CO_APPLICANT ELSE NULL END) AS name_2
      ,MAX(CASE WHEN RN = 2 THEN CO_ADDRESS   ELSE NULL END) AS ADDRESS_2
      ,MAX(CASE WHEN RN = 3 THEN CO_APPLICANT ELSE NULL END) AS name_3
      ,MAX(CASE WHEN RN = 3 THEN CO_ADDRESS   ELSE NULL END) AS ADDRESS_3
FROM TEMP
GROUP BY ID, NAME, ADDRESS;

在您指定确定性order子句之前，SQL表表示无序集。所以我使用ORDERBY子句作为co_申请人名称。因此，从您的样本数据来看，Sanjay位于第二列，Vihjay位于第三列

是小提琴。

您可以按如下方式使用

：

  2  (

---------- ----- -------- ------ -------- ------ -------- ------ --------
       101 aamir address1 rahul  london   vijay  Paris    sanjay New York

注意：由于oracle不允许在查询中使用动态列，因此它将只生成3种名称和地址组合。如果存在3个以上的共同申请人，则仅获取3个共同申请人的数据

--更新--

如果您有多个ID，请使用

行编号

中的

分区依据

子句，如下所示：

SQL> WITH DATAA AS
  2  (
  3  SELECT 101 ID, 'aamir' name, 'address1' address, 'rahul' co_applicant, 'london' co_address FROM DUAL UNION ALL

干杯

请提供输入值，在网站上的预期输出，而不是作为图像，以便在帮助他们可以使用插入和更新。此外，发布您试图获得的期望输出。Aamir Khan，是否没有固定的共同申请人或他们是可变的？申请人的数量最多可以是5个。它适用于一个ID，但我的记录有多个ID和多个与唯一ID相关的列。好，您可以在更新部分great@tejash it works中提到的第_行中使用PARTITION BY子句。还有一个帮助，如何更改通过枢轴的列的位置？请更改（1,2,3）中RN的

中的顺序或使用外部选择更改更具体的顺序。
