Cognos Report Studio 10.2.2 case语句sql逻辑

Question

我试图让这个 sql 逻辑工作，最后一部分是我的逻辑不正确。

我需要为已列为 ID_1 和 ID_2 的提供者恢复重新接纳。如果一个人在 30 天内获得了重新接纳，那么即使他们去了另一个地方，他们也会得到一个 readmit_conf_30 号码。我需要在报告中包含原始提供者编号和其他提供者，如果他们在 30 天内重新接纳的话。

我尝试了很多方法，但不知如何措辞。 Group1 适用于我正在寻找的提供商。 Group2 用于其他提供商。 Group3 将它们联合在一起，Group4 我尝试将它们分配为 Y/N 是否我希望它们出现在报告中。这就是我需要案例逻辑帮助的地方。

感谢您的帮助。

代码：

WITH Group1 AS

我想通了。 SQL 代码如下：-

WITH Group1 AS (
        SELECT A.MEMBER, B.SEX, B.DOB, B.LAST_NAME, B.FIRST_NAME, A.PROVIDER_ID,    C.PROVIDER_NAME
        , A.CONF_NUM, A.BEG_DT, A.END_DT, A.TOS_I_4, A.DIS_STAT, A.AMT_EQV,        A.AMT_PAY, A.AMT_REQ
        , A.READMIT_INDEX_30, A.READMIT_30, A.READMIT_CONF_30
        FROM CONFINEMENTS A 
        LEFT JOIN MEMINFO B ON A.MEMBER = B.MEMBER 
        LEFT JOIN PROVINFO C ON A.PROVIDER_ID = C.PROVIDER_ID
        LEFT JOIN MAP_DATE_RANGE D ON D.IA_TIME = A.IA_TIME
        WHERE A.CUST_OPL_MED IN ('A$*', 'B$*', 'N$*', 'P$*', 'D$*', 'Unspecified$UNK')
        AND A.BEG_DT >= '05/01/2013' and A.beg_dt <'05/01/2014' 
        and A.PROVIDER_ID  Like '341425870%'  
        and (A.READMIT_30 = 1 OR A.READMIT_30 = 0)
),
GROUP2 AS (
       SELECT AA.MEMBER, AA.READMIT_CONF_30
       FROM Group1 AA
       WHERE AA.READMIT_CONF_30 > 0
),

       Select AA.MEMBER, A.READMIT_CONF_30, A.CONF_NUM
       ,B.SEX, B.DOB, B.LAST_NAME, B.FIRST_NAME, A.PROVIDER_ID, C.PROVIDER_NAME
       , A.BEG_DT, A.END_DT, A.TOS_I_4, A.DIS_STAT, A.AMT_EQV, A.AMT_PAY, A.AMT_REQ
       , A.READMIT_30, A.READMIT_INDEX_30
       FROM GROUP2 AA
       LEFT JOIN CONFINEMENTS A ON A.MEMBER = AA.MEMBER AND AA.READMIT_CONF_30 = A.CONF_NUM

       and (A.READMIT_30 = 1 OR A.READMIT_30 = 0)
)
      select 
      MEMBER, READMIT_CONF_30
      ,SEX, DOB, LAST_NAME, FIRST_NAME, PROVIDER_ID, PROVIDER_NAME
      , CONF_NUM, BEG_DT, END_DT, TOS_I_4, DIS_STAT, AMT_EQV, AMT_PAY, AMT_REQ
      , READMIT_30, READMIT_INDEX_30
      from group1
      union 
      select 
      MEMBER, READMIT_CONF_30
     ,SEX, DOB, LAST_NAME, FIRST_NAME, PROVIDER_ID, PROVIDER_NAME
     , CONF_NUM, BEG_DT, END_DT, TOS_I_4, DIS_STAT, AMT_EQV, AMT_PAY, AMT_REQ
