Hi All
I have executed the below procedure. I got the below error. My doubt is why should I used GroupBy clause from Product_Name. If I am not using Group by clause, error is thrown up.
Create Procedure "Sales-Product"."Sales"
(IN Discount Integer ,
OUT OUTPUT_TABLE "Sales-Product"."TT-Sales") AS
BEGIN
VAR1 = SELECT T1.REGION_NAME,T1.SUB_REGION_NAME,T2.PRODUCT_ID,T2.SALES_AMOUNT
From "Sales-Product"."REGION" AS T1
INNER JOIN
"Sales-Product"."SALES" As T2
ON T1.REGION_ID = T2.REGION_ID;
VAR2 = SELECT T1.REGION_NAME,T1.SUB_REGION_NAME,T1.PRODUCT_ID,T1.SALES_AMOUNT,T2.PRODUCT_NAME
From :VAR1 AS T1
INNER JOIN
"Sales-Product"."PRODUCT" AS T2
ON T1.PRODUCT_ID = T2.PRODUCT_ID;
OUTPUT_TABLE = SELECT SUM(SALES_AMOUNT) AS SALES_AMOUNT ,
PRODUCT_NAME,
PRODUCT_ID,
REGION_NAME,
SUB_REGION_NAME
FROM :VAR2;
END
Error :
SAP DBTech JDBC: [260] (at 675): invalid column name: The column 'VAR2.PRODUCT_NAME' is invalid in the select list because the GROUP BY clause or an aggregation function does not contain it: line 16 col 25 (at pos 675)
