Hello:

I have this SQL Statement: SELECT Count(FinalData) AS Total FROM Data
It displays the results in a row like this:

34
78
44
90
35

The results are correct. How can I sum the results after I count them?

Add the following at the end of the SELECT statement -

COMPUTE SUM(COUNT(FINALDATA))

``````SELECT sum(Count(FinalData)) AS Total FROM Data
``````

Gallitin -> Your query will yield the following error message -

Cannot perform an aggregate function on an expression containing an aggregate or a subquery.

The count(finaldata) in the original query is resulting in multiple rows because there is a grouped field which has not been indicated in the question. Otherwise a mere count(finaldata) should suffice..

SELECT COUNT(FINALDATA)  AS Total
FROM Data
COMPUTE SUM(COUNT(FINALDATA))

This gives me the same result

What is your expected result? Are you looking for this? Do yu have GROUP BY clause in your original query?

SELECT SUM(Total) FROM (SELECT COUNT(FINALDATA) AS Total FROM Data ) T1
