SQL UPDATE錯誤

Question

我很感激我的代碼任何幫助，我不斷收到一個錯誤

SQL命令無法正常從蟾蜍結束」。

UPDATE GS_MRC_EXISTING GME 
SET GME.GROSS_LAST = STC.SALES 
WITH STC AS 
( 
SELECT DISTINCT (DSF.SOLD_TO_CUSTOMER_KEY) AS CUSTS, 
      SUM (CASE WHEN DSF.NET_PRICE >=0 THEN NET_PRICE ELSE 0 END ) AS SALES, 
      SUM (CASE WHEN DSF.NET_PRICE <=0 THEN NET_PRICE ELSE 0 END ) AS DISCOUNT 
FROM DAILY_SALES_FACT DSF, 
      MATERIAL_DIM MD  
WHERE 
DSF.SALES_DOC_TYPE_SID = '10' 
AND DSF.MATERIAL_SID = MD.MATERIAL_SID 
AND DSF.NET_PRICE <> 0 
AND DSF.TPNM_ACTUAL_START_DATE_KEY BETWEEN '20160101' AND '20160731' 
GROUP BY DSF.SOLD_TO_CUSTOMER_KEY 
) 
WHERE GME.CUST_CODE = STC.CUSTS; 

Answer 1

也許你應該刪除後 「UPDATE」 命令 「和」 部分。如果按字段對結果進行分組，則不能在該字段上使用「distinct」。像這樣：

WITH STC AS 
(
    SELECT DSF.SOLD_TO_CUSTOMER_KEY AS CUSTS, 
     SUM (CASE WHEN DSF.NET_PRICE >=0 THEN NET_PRICE ELSE 0 END ) AS SALES, 
     SUM (CASE WHEN DSF.NET_PRICE <=0 THEN NET_PRICE ELSE 0 END ) AS DISCOUNT 
    FROM DAILY_SALES_FACT DSF, 
     MATERIAL_DIM MD 
    WHERE 
     DSF.SALES_DOC_TYPE_SID = '10' 
     AND DSF.MATERIAL_SID = MD.MATERIAL_SID 
     AND DSF.NET_PRICE <> 0 
     AND DSF.TPNM_ACTUAL_START_DATE_KEY BETWEEN '20160101' AND '20160731' 
    GROUP BY DSF.SOLD_TO_CUSTOMER_KEY 
) 
UPDATE GS_MRC_EXISTING SET GROSS_LAST = STC.SALES WHERE CUST_CODE = STC.CUSTS; 

Answer 2

Toad建議Oracle。這表明，子查詢對於這樣的update（或merge）：

UPDATE GS_MRC_EXISTING GME 
    SET GME.GROSS_LAST = (SELECT SUM(CASE WHEN DSF.NET_PRICE >= 0 THEN NET_PRICE ELSE 0 END ) AS SALES 
          FROM DAILY_SALES_FACT DSF JOIN 
           MATERIAL_DIM MD 
           ON DSF.MATERIAL_SID = MD.MATERIAL_SID 
          WHERE DSF.SALES_DOC_TYPE_SID = '10' AND 
           DSF.NET_PRICE <> 0 AND 
           DSF.TPNM_ACTUAL_START_DATE_KEY BETWEEN '20160101' AND '20160731' AND 
           DSF.SOLD_TO_CUSTOMER_KEY = GME.CUST_CODE 
         ); 

注意：這將更新所有的行，即使是那些不匹配。您可能想要限制：

UPDATE GS_MRC_EXISTING GME 
    SET GME.GROSS_LAST = (SELECT SUM(CASE WHEN DSF.NET_PRICE >= 0 THEN NET_PRICE ELSE 0 END ) AS SALES 
          FROM DAILY_SALES_FACT DSF JOIN 
           MATERIAL_DIM MD 
           ON DSF.MATERIAL_SID = MD.MATERIAL_SID 
          WHERE DSF.SALES_DOC_TYPE_SID = '10' AND 
           DSF.NET_PRICE <> 0 AND 
           DSF.TPNM_ACTUAL_START_DATE_KEY BETWEEN '20160101' AND '20160731' AND 
           DSF.SOLD_TO_CUSTOMER_KEY = GME.CUST_CODE 
         ) 
WHERE EXISTS (SELECT 1 
       FROM DAILY_SALES_FACT DSF JOIN 
        MATERIAL_DIM MD 
        ON DSF.MATERIAL_SID = MD.MATERIAL_SID 
       WHERE DSF.SALES_DOC_TYPE_SID = '10' AND 
        DSF.NET_PRICE <> 0 AND 
        DSF.TPNM_ACTUAL_START_DATE_KEY BETWEEN '20160101' AND '20160731' AND 
        DSF.SOLD_TO_CUSTOMER_KEY = GME.CUST_CODE 
      );
