SELECT  DirName, count(*) AS FileCount, SUM(Size)/1024 as 'SizeKB' 
FROM  alldocs
Where DirName = 'site/test/test/*'
GROUP BY  dirName 
ORDER BY DirName

Answer 1

You need to use SQL's LIKE clause:

SELECT  DirName, count(*) AS FileCount, SUM(Size)/1024 as 'SizeKB' 
FROM  alldocs
Where DirName LIKE 'site/test/test/%'
GROUP BY  dirName 
ORDER BY DirName

See http://www.sql-tutorial.net/SQL-LIKE.asp

Answer 2

Are you using MySQL? If you are, you can use LEFT in something like

SELECT  DirName, count(*) AS FileCount, SUM(Size)/1024 as 'SizeKB' 
FROM  alldocs
Where LEFT( DirName, LENGTH( 'site/test/test/' ) ) = 'site/test/test/'
GROUP BY  dirName 
ORDER BY DirName
