Cognos Report Studio 10.2.2 case語句sql邏輯

Question

我想讓這個sql邏輯工作，最後一部分是我沒有我的邏輯正確的地方。

我需要爲已列爲ID_1 & ID_2的提供程序重新提供重新發送。如果一個人在30天內有重新發帖，那麼即使他們去了另一個地方，他們也會得到一個readmit_conf_30號碼。如果他們在30天之內有重新發帖，我需要在報告中包含原始提供商號碼和其他提供商。

我已經嘗試了很多方法，並且對如何使用它而感到茫然。 Group1適用於我在尋找的提供商。 Group2適用於其他提供商。第3組將它們組合在一起，第4組我嘗試將它們分配給Y/N，無論我是否希望他們報告。這是我需要案例邏輯幫助的地方。

感謝您的幫助。

代碼：

WITH Group1 AS

Answer 1

我想通了。 SQL代碼如下： -

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 
), 
Group3 AS (
     Select AA.MEMBER, A.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
