Decode function... total at the end

Question

Hi,
I am using following query to show results...
Select
ACCOUNT_CONSULTANT,
max((DECODE (SALES_STAGE, 'MEETING', Opportunities, NULL)
)) MEETING,
max((DECODE (SALES_STAGE, 'CLOSED', Opportunities, NULL)
)) CLOSED,
max((DECODE (SALES_STAGE, '', Opportunities, NULL)
)) TBD
From
select
ACCOUNT_CONSULTANT,
SALES_STAGE,
count(PROSPECT_NAME) as Opportunities
from Table_A
group by
ACCOUNT_CONSULTANT,
SALES_STAGE
group by
ACCOUNT_CONSULTANT
order by
ACCOUNT_CONSULTANT
results appear as follows
Acct_Conslt Meeting Closed TBD
Sales RepA 6 1 11
what I want is the total at the end, something like this
Acct_Conslt Meeting Closed TBD Total
Sales RepA 6 1 11 18
Please advice

Hi,
Assuming your present query is getting the right results, you can make it a sub-query. Just copy the whole query (except the ORDER BY clause) into a WITH clause or an in-line view. Then, in the main query, you can reference the computed columns meeting, closed and tbd, like this:
WITH     got_aggregates     AS
     Select
     ACCOUNT_CONSULTANT,
     max((DECODE (SALES_STAGE, 'MEETING', Opportunities, NULL)
     )) MEETING,
     max((DECODE (SALES_STAGE, 'CLOSED', Opportunities, NULL)
     )) CLOSED,
     max((DECODE (SALES_STAGE, '', Opportunities, NULL)
     )) TBD
     From
     select
     ACCOUNT_CONSULTANT,
     SALES_STAGE,
     count(PROSPECT_NAME) as Opportunities
     from Table_A
     group by
     ACCOUNT_CONSULTANT,
     SALES_STAGE
     group by
     ACCOUNT_CONSULTANT
SELECT       a.*
,       meeting + closed + tbd          AS total
FROM       got_aggregates   a
ORDER BY  account_consultant
;If the components of total can be NULL, then you'd better compute total like this:
,       NVL (meeting, 0) +
       NVL (closed,     0) +
       NVL (tbd,     0)          AS totalEdited by: Frank Kulash on Jun 3, 2010 5:39 PM
