Hi I'm the author of DBD::RAM so here's the scoop right from the horse's mouth (now is that a bad mixed metaphor or what?).

1. DBD::RAM is soon to be replaced by DBD::AnyData which handles CSV, XML, Fixed Width Records and many more formats, see its home page at http://www.vpservices.com/jeff/programs/AnyData/ including reviews by Randal and by Michel Rodriguez.

2. DBD::CSV, DBD::RAM, DBD::AnyData all depend on Jochen Wiedman's SQL::Statement to do SQL parsing.

3. SQL::Statement does *NOT* support joins.

4. I have agreed with Jochen to take over maintenance of SQL::Statement but I'm afraid I'm behind on getting to it. If anyone is interested in helping out with it, let me know.

5. I have also created AnyData.pm, a non-DBI, tied-hash access to all the formats supported by DBD::AnyData. It does allow simple joins by using queries in one table to be the key to a hash into another table.

6. It is possible to accomplish simple joins with any of the above mentioned DBDs by opening multiple statement handles for the multiple tables and doing nested fetch loops. I can supply an example if needed.

7. Good luck!
