在 select 语句中链接查询

Question

From the query i am able to return the output as expected ..

是否可以使用 select 语句在下面标记的引号中编写相同的查询：

SELECT ACC.ACCOUNT_NUM AS ACCOUNT_NUMBER,
   ACC.ACCOUNT_NAME AS ACCOUNT_NAME,
   ADR.ADDRESS_1 AS BUILDING_TYPE,
   ACC.CUSTOMER_REF AS CUSTOMER_ID,
   CAT.BC AS BILL_CYCLE,
   CES.EVENT_SOURCE AS TELEPHONE_NUMBER,
   AAT.PACKAGE_NAME AS PROMO_PACKAGE,
   PRD.PRODUCT_NAME AS SERVICES,
   (SELECT COUNT (DISTINCT (EVENT_SOURCE))
      FROM CUSTEVENTSOURCE CES1
     WHERE CES1.CUSTOMER_REF = ACC.CUSTOMER_REF AND END_DTM IS NULL)
      AS TOTAL_NUMBER,
   ("SELECT LISTAGG (EVENT_SOURCE, ', ')
              WITHIN GROUP (ORDER BY EVENT_SOURCE)
      FROM CUSTEVENTSOURCE
     WHERE CUSTOMER_REF = ACC.CUSTOMER_REF AND END_DTM IS NULL")
      AS ALL_IPHONE_NUMBERS,
   CUS.COMPANY_NAME AS COMPANY_NAME,
      ADR.ADDRESS_1
   || ' '
   || ADR.ADDRESS_2
   || ' '
   || ADR.ADDRESS_3
   || ' '
   || ADR.ADDRESS_4
   || ' '
   || ADR.ADDRESS_5
      AS BILLING_ADDRESS,
   (SELECT ADR.ADDRESS_1
      FROM ADDRESS ADR
     WHERE ADR.CUSTOMER_REF = ACC.CUSTOMER_REF
           AND ADDRESS_SEQ IN
                  (SELECT ADDRESS_SEQ
                     FROM CUSTPRODUCTADDRESS CPA
                    WHERE CPA.CUSTOMER_REF = ADR.CUSTOMER_REF

                                                (SELECT MAX (
                                                           EFFECTIVE_DTM)
                                                   FROM CUSTPRODUCTSTATUS CPS1

你能帮帮我吗..我是 sql 新手..请

提前谢谢..

以上需要在""双引号内改 输出如下：

ACCOUNT_NUMBER     ACCOUNT_NAME  BUILDING_TYPE  CUSTOMER_ID  TELEPHONE_NUMBER  PROMO_PACKAGE TOTAL_NUMBER   ALL_IPHONE_NUMBERS,

MTX000110       John             xxxx            10002         123456     yyy    3   001-003,004,007

如果帐户有 3 个totoal_number，则在 All_iphone_numbers 列中，如果值具有序列号，则应使用“-”分隔符，否则必须显示数字

如果我使用“”双引号数组..我得到的输出是逗号分隔值，结果不正确..结果应该看起来像“如果值有序列号，那么它应该'-'否则带有分隔符它必须显示数字”。

试试这个：（注意：我没有11G R2，所以我用wm_concat测试，不支持，但是如果你有11G R2，那就用LISTAGG）

WITH TABIBITOSAN
    AS (SELECT
             ACCOUNT_REF,
             "number",
             TO_NUMBER ( "number" )
             - ROW_NUMBER ( ) OVER (ORDER BY TO_NUMBER ( "number" ))
                 AS GRP
        FROM
             TBL),
    DATASET1
    AS (SELECT
             ACCOUNT_REF,
             CASE
                 WHEN MIN ( "number" ) = MAX ( "number" )
                 THEN
                     MIN ( "number" )
                 ELSE
                        MIN ( "number" )
                     || '-'
                     || MAX ( "number" )
             END
                 AS RANGES
        FROM
             TABIBITOSAN
        GROUP BY
             ACCOUNT_REF,
             GRP
        ORDER BY
             ACCOUNT_REF,
             MIN ( "number" ))
SELECT
      ACCOUNT_REF,
      WM_CONCAT ( RANGES ) AS NEW_RANGES
FROM
      DATASET1
GROUP BY
      ACCOUNT_REF;

结果：

101 002-004,006-008,011

使用 LISTAGG

SELECT
      ACCOUNT_REF,
      LISTAGG ( RANGES,
              ',' )
      WITHIN GROUP (ORDER BY RANGES)
          AS NEW_RANGES
FROM
      DATASET1
WHERE
      ACCOUNT_REF = ACC.ACCOUNT_REF
GROUP BY
      ACCOUNT_REF
