SQL Interpreter

[Guest_imported]

I know that i lot of people may declare me nuts after this post. but who cares

i want to write a simple SQL-interpreter that can run queries on a pure XML-database. However, i cannot get the joins to work (or the GROUP BY's for that matter). Is there someone who knows how both algorithms work? Or are there any existing interpreters that give insight in what the query is doing?

hi Tek,

Interesting....

You might take a look at the DBI - a Perl module that allows access to many different databases.

Each supported database needs a DBD (Database Driver) and there are drivers for text file and in-memory databases that would probably give you a starting point.
