in the same way that TTable does. Double click on the components to get the
field list and add all fields. then select the one you want to be boolean
and set the properties for tru and false values.

than later you will need to scope your datasets with WHERE clauses if you
work against any SQL database server for best performance. If you have 90%
tables, then you can bet your life that a lot of the app will be trying to
drag all rows in the tables off the server when it should be trying to leave
as many on the server as possible.
