Question

I am Aggregating the data on ‘INTERIM_AUTO’ table on the basis of Unit ID, Line ID, CURR_DATE i.e.

SELECT INTERIM_AUTO_ID,
       UNIT_ID,
       PROD_LINE_ID,
       CURR_DATE,
       BAL_AMOUNT,
       V_SOURCE_CODE,
       CURR_ID,
       CREATED_BY,
       UPDATED_DATETIME
  FROM INTERIM_AUTO
 WHERE CURR_DATE = to_date(V_DATE, 'MM/DD/YYYY')
 GROUP BY UNIT_ID,
          PROD_LINE_ID,
          CURR_DATE

And then if we get multiple entries for the above combination then I have to do the summation of BAL_Amount and consider the single entry for the above combination with this calculated Amount. How do I achieve this?

Answer 1

It sounds like you want to calculate the sum of the BAL_AMOUNT column. You can do this with the SUM function.

If you use SUM on your BAL_AMOUNT column, you will have to add all your other columns into the GROUP BY:

   SELECT INTERIM_AUTO_ID,
          UNIT_ID,
          PROD_LINE_ID,
          CURR_DATE,
          SUM(BAL_AMOUNT) as SUM_BAL_AMOUNT,
          V_SOURCE_CODE,
          CURR_ID,
          CREATED_BY,
          UPDATED_DATETIME
     FROM INTERIM_AUTO
    WHERE CURR_DATE = to_date(V_DATE, 'MM/DD/YYYY')
 GROUP BY UNIT_ID,
          PROD_LINE_ID,
          CURR_DATE,
          INTERIM_AUTO_ID,
          UNIT_ID,
          PROD_LINE_ID,
          V_SOURCE_CODE,
          CURR_ID,
          CREATED_BY,
          UPDATED_DATETIME;

Or remove the columns you don’t need:

   SELECT UNIT_ID,
          PROD_LINE_ID,
          CURR_DATE,
          SUM(BAL_AMOUNT) as SUM_BAL_AMOUNT
     FROM INTERIM_AUTO
    WHERE CURR_DATE = to_date(V_DATE, 'MM/DD/YYYY')
 GROUP BY UNIT_ID,
          PROD_LINE_ID,
          CURR_DATE;
