Hey hey guys!

Well, I am trying to finish a query that is a little bit complex, but I try in the begging to explain with words and then I share the query with you guys.

-First column - shows me the type of some file(.exe, .pdf, ...)
-Second column - shows me the percentage of that file on the database
-Third column(Here it's where the problem comes) - should show me the size of every type of file and then below the total.

This is the output with this query without giving me the size of each type of files

Filetype | Percentagem | Total (KB)
.pdf        25%         25
.dll        45%         300

This is my query:
SELECT Filetype,
((COUNT(Filetype) * 100) / (SELECT COUNT(*) FROM infofile)) AS Percentagem,
NULL AS 'Total (KB)'
FROM infofile
GROUP BY Filetype
FROM infofile

What I want to get to is the size of each Filetype in the Total(KB) column.

Thank you for your help. Have a great day

What I have tried:

I've tried to simulate adding another select that actually works but independent from the main query.

SELECT Filetype, SUM(Filesize) AS 'Total(KB)'
FROM infofile
GROUP BY Filetype

What is your table schema?

How can I post a print here?

You can't - just list the columns and their types
Member 12490691 3-May-16 12:42pm    
What you clearly want?
CHill60 3-May-16 12:45pm    
I guessing that your table contains
FileType int,
FileSize int,
... something else.
Also some sample data (5 or 6 rows only) of what is on the table - not the output from your query

hi you can try this

SELECT id, code,
    (SELECT SUM(id) AS sumid
     FROM tbl_wtr
     WHERE (accid = AS sumid
    (SELECT id, code
     FROM tbl_stacc) AS newtb

Hey. Thank you for your solution. Your query does not apply with the query that I am trying to build.

What I have in my query is actually working but instead of using that 'NULL AS 'TOTAL(KB)' I would like to use a SELECT to query me what I want in that column.

This is the Select that I want to include in my query
SELECT Filetype, SUM(Filesize) AS 'Total(KB)'
FROM infofile
GROUP BY Filetype
