Well, although you can read the VFP manuals, I think there is no substitute for experimenting.

Did you use queries? If you didn't, you should start with the query designer:

CREATE QUERY

or

MODIFY QUERY

This will create a program with extension .QPR, which you can then run with DO (or you can copy the code to another program)

Try some simple experiments first, and then more complicated ones:
  • Select specific fields from a single table.
  • Add a filter condition.
  • Combine data from two tables.

    All this will create a read-only cursor - you can't update the original tables. If you already did all this, we can continue with views.

    Greetings,

    Hilmar.
