Ok, think don't thought about that way ^^

But what happens with other functions, for example SUM, MIN and MAX.

I'm not sure if the SQL standard will force to use the brackets for some functions.

By the way the, there ist something more to change in the function :

elsif($raw =~ /\s/) { 

had to be

elsif($raw =~ /[\s()]/) {

Regards,

Lars
