Actually, the joining claim was a bit bold - it's been a while since I've used 
the admin tool, and forgot how it worked :) Having said that though, does 
your SQL database already come with all the reports you'd want to create? ;)

You will need to write reports, yes. Since roundup doesn't have a query 
language, they will be more verbose than SQL. See the roundup-reminder 
example script:

To clarify on the whole SQL deal (I hope): without a fair bit of effort 
customising a backend for layering over an SQL database, SQL queries on an 
SQL backend are going to look fairly hideous. One of the biggies is the 
Multilink property available in the hyperdb, which would need a separate 
table if implemented half-decently in SQL.

If you want to do lots of SQL, you'll probably want to either invest the time 
in developing a hyperdb-over-SQL, or you're going to want to look elsewhere.
