總結基於條件的行

我正在使用db2數據庫（不確定版本）。我的腳本是功能性的，但我沒有產生我期望的結果。我需要根據我的情況聲明中的條件將我的總計總計分成3組，但是對於同一個project_name/id和building_name/id下的每個項目，我需要每個項目的每個項目名稱/ id只有一行的總數building_name/ID。我假設某個組或某個遞歸函數是解決方案，但我不太確定。希望能朝着正確的方向前進。這是我的腳本。總結基於條件的行

SELECT 
     DP.DIM_PROJECT_ID, 
     DP.PROJECT_NAME, 
     DM.DIM_BUILDING_ID, 
     DM.BUILDING_NAME, 
     CASE WHEN (DJ.GROUPS3 IN ('33.3% <= x <= 100%', '16.7% <= x < 33.3%') AND DA.TYPE_NAME = 'SALES') 
     THEN cast(sum(cast(FAT.TRANSACTION_AMOUNT as real)) as integer) 
     WHEN (DJ.GROUPS3 IN ('60% <= x <= 100%', '20% <= x < 60%') AND DA.TYPE_NAME = 'SALES') 
     THEN cast(sum(cast(FAT.TRANSACTION_AMOUNT as real)) as integer) 
     ELSE '0'  
     END as CAPABILITY,  
     CASE WHEN (DJ.GROUPS3 = '0% <= x < 16.7%' AND DA.TYPE_NAME = 'SALES') 
     THEN cast(sum(cast(FAT.TRANSACTION_AMOUNT as real)) as integer) 
     WHEN (DJ.GROUPS3 = '0% <= x < 20%' AND DA.TYPE_NAME = 'SALES') 
     THEN cast(sum(cast(FAT.TRANSACTION_AMOUNT as real)) as integer) 
     ELSE '0'    
     END as GROUP_1, 
     CASE WHEN (DJ.GROUPS3 = '16.7% <= x < 33.3%' AND DA.TYPE_NAME = 'SALES') 
     THEN cast(sum(cast(FAT.TRANSACTION_AMOUNT as real)) as integer) 
     WHEN (DJ.GROUPS3 = '20% <= x < 60%' AND DA.TYPE_NAME = 'SALES') 
     THEN cast(sum(cast(FAT.TRANSACTION_AMOUNT as real)) as integer)  
     ELSE '0'   
     END as GROUP_2, 
     CASE WHEN (DJ.GROUPS3 = '33.3% <= x <= 100%' AND DA.TYPE_NAME = 'SALES') 
     THEN cast(sum(cast(FAT.TRANSACTION_AMOUNT as real)) as integer) 
     WHEN (DJ.GROUPS3 = '60% <= x <= 100%' AND DA.TYPE_NAME = 'SALES') 
     THEN cast(sum(cast(FAT.TRANSACTION_AMOUNT as real)) as integer) 
     ELSE '0'    
     END as GROUP_3 
FROM FACT_TABLE as FAT 
RIGHT JOIN DIM_ALLOCATION DA ON FAT.DIM_ALLOCATION_ID = DA.DIM_ALLOCATION_ID 
INNER JOIN DIM_PROJECT DP ON FAT.DIM_PROJECT_ID = DP.DIM_PROJECT_ID 
INNER JOIN DIM_DATE DD ON FAT.ALLOCATION_START_DATE_DIM_ID = DD.DATE_KEY 
INNER JOIN DIM_JOB DJ ON FAT.DIM_JOB_ID = DJ.DIM_JOB_ID 
INNER JOIN DIM_BUILDING DM ON FAT.DIM_BUILDING_ID = DM.DIM_BUILDING_ID 

WHERE 
    DD.DATE_VALUE = '2013' 
    AND DA.BUILDING_NAME IN ('ADMIN', 'INVISION') 


GROUP BY DM.DIM_BUILDING_ID, 
     DP.DIM_PROJECT_ID, 
     DP.PROJECT_NAME, 
     CAPABILITY, 
     DM.BUILDING_NAME, 
     DJ.GROUPS3, 
     DA.TYPE_NAME 
ORDER BY DP.PROJECT_NAME

結果： enter image description here

我找到了答案，並貼在下面了。

cast(SUM(CASE WHEN DJ.GROUPS3 IN ('33.3% <= x <= 100%', '16.7% <= x < 33.3%') 
    THEN cast(FAT.TRANSACTION_AMOUNT as real) 
    WHEN DJ.GROUPS3 IN ('60% <= x <= 100%', '20% <= x < 60%') 
    THEN cast(FAT.TRANSACTION_AMOUNT as real) 
    ELSE NULL 
    END)) as integer) as CAPABILITY,

您拿出總數並在案例聲明之外進行投射。
