Re: InstantDB: Not finding my tables?


Excuse my ignorance but when you say TABLE
should i use the my "Client" table or actually use the word "TABLE"?

What i did try is using what you gave me exactly without changing anything
and what i get
 doesnt seem to have my 3 tables in it.  But if I use SQL Builder I see all
the data.  I really believe
its a path issue.

Any ideas please?
