This is a promising project for those who has no real sql available. i was only wondering if there could be effort for implementing some interaction with linked tables (foreign keys). for example automated deletion of a row if there is reference to another row to be deleted.
fSQL up to v1.3.1 handles keys poorly in general. Foreign keys are ignored. The syntax is accepted but the foreign key information isn't even kept in the table anywhere for to be to be used if I did add support to v1.3.x.
However, the version currently living the SVN branch (currently called v1.4) does add a new standard file formata, including actual key files and more information about keys stored. Foreign keys weren't in the original plan for the initial release, but I could add them to the schedule for it.
I'll be working on fSQL later tonight, so I can start on that soon.
