Apart from providing the connection name, this sounds reasonable. It
could be the first link on the db samples page. Providing the
connection name would entail that all samples could be switched to it
dynamically as well. I wouldn't want that, because it makes the sames
more complex than necessary.

This would probably be the chance to change the "user" table to
e.g. "users" (other suggestions?) so that more DBMSs are happy
(PostgreSQL?)

But, how to go about it? I reckon we still want this .sql
around. Hence we need to parse it and feed it to the DBMS one
statement at a time.... Could be read in through the util logicsheet
and the string tokenizer using ";" as separator. Don't care about ";"
inside of strings :-|
