Database question to Fogcreek

Will CityDesk break or become inoperative if I were to add tables to a .cty file?

Nope.  As long as you don't change the existing structure it shouldn't have an effect.  Run it on a test database just to make sure first.

You can even add columns to existing tables.

Suggestion 1: Give your own tables and columns names that clearly flag they are not part of the Fog Creek schema.

Suggestion 2: Back up everything before you go playing with queries or forms that could alter elements of the Fog Creek tables.

Interesting!

Can I query my new fields with CityScript?

No. Think about this: how would CityScript know about your new fields?

If you do add your own fields and tables, please try to use ridiculous names that have no chance of ever getting in the way of something fog creek puts there in the future. For example "Happy_bunny_My_Silly_Field" and the like...

For example, we always name our tables starting with "tbl" so if you name your tables "mytbl" than future versions of the CityDesk database format will never conflict.
