I think if u need to work with alot of tables and relations, a generic ZSQLMethod is pretty useful. It sure make things a lot easier for me. At least I get to see how my SQL statement is structured before sending it to the DBMS. Now I still need to figure out a easy way to join two relations from two databases. :(
Bad idea! Unless you have only a completly trusted audience that never
You will be allowing anyone who can access your zope to do anything they
want to your database, including deleting tables, and, if you are
really unlucky, this could be caused by an honest mistake of dropping a
quote mark, or accidentally inserting a semi-colon.
The reason that ZSQL methods exist (and have special quoting
conventions) is to stop SQL injection. Do not make your methods less
secure than they need to be!
