Has anybody build a rank function in Servoy?
I need to build in Servoy the same rank function that it’s found in Excel.
Any clues in this regard will be more than appreciated!

Servoy doesn’t have a rank function but the bundled database (PostgreSQL) does.
The syntax looks like this:
SELECT id,num,rank FROM (
SELECT id,num,rank() OVER (ORDER BY num) FROM foo
) AS bar WHERE id=2
For more information check out the excellent PostgreSQL documentation:
http://www.postgresql.org/docs/8.4/stat … indow.html

You find these window functions in other brands of databases as well (MSSQL/Oracle/etc., not MySQL though)
Hope this helps.
Rob, thanks a bunch!
