I have the below issues that I would like to address:
Below is my query:
SELECT
status AS "ROW LABELS",
COUNT(case when source = 'INTERNET' THEN 1 end) AS "INTERNET",
COUNT(case when source = 'SALES' THEN 1 end) AS "SALES",
COUNT(case when source = 'REP' THEN 1 end) AS "REP",
COUNT(case when source = 'COM' THEN 1 end) AS "COM",
(COUNT(case when source = 'INTERNET' THEN 1 end) +
COUNT(case when source = 'SALES' THEN 1 end) +
COUNT(case when source = 'REP' THEN 1 end) +
COUNT(case when source = 'COM' THEN 1 end)
) AS Total
FROM
SOMETABLE
GROUP BY ROLLUP((status))
order by 1;
Below is my data:
If by "simplify" you mean "make the calculation more succinct", then yes. The following will work:
COUNT(CASE WHEN source IN ('INTERNET', 'SALES', 'REP', 'COM') THEN 1 END)
Simply use nvl
to convert the NULL to a value: NVL(status, 'TOTAL') AS row_labels
ROLLUP( (status) )
is the same as ROLLUP( status )
