Usecase with simple SQL query

Hello,

I'm going to create a number of usecase that query a sql database  
(using mysql) and I know that I could use some java code to access the  
database, but the cocoon documentation also explains how to use  
<sql:execute-query> which seems what I need.

Unfortunately I can't get it to work. Does someone have an example?  
How does the <sql:execute-query> get transformed?

Thank you,

René
