Help on Aggregated Columns Through SQL

Question

Hello All,
This is Sam, I am trying to pull the data from a table based on following criteria
1) Month To Date
2) Yesterday only
3) Whole Month
Below is the sql i created i could able to achieve SUM(NET_AMT) aggregated value for the Month To Date but could not able to figure out how i could create additional calculated columns for the other 2 criteria, could you please help me with the below query, the WITH clause i used is just to bring the total days in current month and current day number in the respective month, i think GROUP BY clause could not specified in CASE statement to aggregate based on dates, i am puzzled how to proceed further, appreciate your help, Thank you.
WITH X_DATE_H AS(
SELECT
PREV.DAY_DT AS PREV_DAY,
PREV.DAY_OF_MONTH AS CURR_DAY_MTD,
PREV.M_STRT_CAL_DT_WID AS MON_START_DAY_WID,
PREV.M_END_CAL_DT_WID AS MON_END_DAY_WID,
(PREV.M_END_CAL_DT_WID - PREV.M_STRT_CAL_DT_WID + 1) AS NO_DAYS_IN_MONTH
FROM W_DAY_D PREV, W_DAY_D CURR
WHERE CURR.DAY_DT = TRUNC(SYSDATE)
AND CURR.DAY_AGO_WID = PREV.ROW_WID
SELECT
SYSDATE AS SNAPSHOT_DATE,
TO_CHAR(SYSDATE,'YYYYMMDD') AS SNAPSHOT_DATE_WID,
PROD.PRODUCT_TYPE_CODE,
PROD.PRODUCT_TYPE_DESC,
X_DATE_H.CURR_DAY_MTD AS DAYS_MTD,
X_DATE_H.NO_DAYS_IN_MONTH AS DAYS_MONTH,
SUM(NET_AMT) AS BOOKING_AMT
FROM
X_DATE_H,
W_SALES_BOOKING_LINE_F BKG_F
LEFT JOIN W_PRODUCT_D PROD ON BKG_F.PRODUCT_WID=PROD.ROW_WID
LEFT OUTER JOIN W_INT_ORG_D ON (BKG_F.X_BRANCH_WID = W_INT_ORG_D.ROW_WID AND BKG_F.DATASOURCE_NUM_ID=W_INT_ORG_D.DATASOURCE_NUM_ID)
WHERE
BKG_F.X_MONTH_WID BETWEEN TO_CHAR(LAST_DAY(ADD_MONTHS(SYSDATE,-1))+1,'YYYYMMDD') AND TO_CHAR(SYSDATE,'YYYYMMDD')
GROUP BY SYSDATE, TO_CHAR(SYSDATE,'YYYYMMDD'), PROD.PRODUCT_TYPE_CODE,PROD.PRODUCT_TYPE_DESC,X_DATE_H.CURR_DAY_MTD,X_DATE_H.NO_DAYS_IN_MONTH

Hi, Sam,
Whenever you have a question, it helps to post:
(1) The version of Oracle (and any other relevant software) you're using
(2) A little sample data (just enough to show what the problem is) from all the relevant tables. You can probably post a good example with just 2 products and 3 dates.
(3) The results you want from that data
(4) Your best attempt so far (formatted) (You posted this, but since it's unformated, it's very hard to read.)
Executable SQL statements (like "CREATE TABLE AS ..." or "INSERT ..." statements) are best for (2).
Formatted tabular output is okay for (3). Type these 6 characters:
{code}
(small letters only, inside curly brackets) before and after formatted text, to preserve spacing.
Analytic functions are very good for doing things like running totals (such as month-to-date).
SYSDATE is constant with any query, even if the query takes a long time to run.
There's no point in grouping by a constant, so
GROUP BY  SYSDATE
,         TO_CHAR (SYSDATE,'YYYYMMDD')
,         PROD.PRODUCT_TYPE_CODE
,         ...produces the same results as
GROUP BY  PROD.PRODUCT_TYPE_CODE
,         ...
