Can I Use Oracle Analytical Function Here?

I've got this query: SELECT year, month, week, C.cpg_pk CPG, C.dep_pk

Solution 1:

Sure, you can use analytics, something like this:

SELECT DISTINCT YEAR, MONTH, WEEK, CPG, DEPT, CUST_ID, R_ID,
       SUM(P1) OVER (PARTITION BY YEAR,MONTH,WEEK, CPG, DEPT, CUST_ID, R_ID) P1,
       SUM(IC) OVER (PARTITION BY YEAR,MONTH,WEEK, CPG, DEPT, CUST_ID, R_ID) IC,
       SUM(B1) OVER (PARTITION BY YEAR,MONTH,WEEK, CPG, DEPT, CUST_ID, R_ID) B1, 
       P2, B2, TOT, TOTAL_TXN, TOTAL_AMT 
  FROM (your_query)
