Hi,
I have two tables in a Database.
One table: called "People". It has list of peoples and their Emails.
Second table: called "Mailing" Has email from table one.
I would like to set an new field in "People" (table 1) that marks "1" if an email is present in both tables. I called this field "Did_I_found_Email" (1 = yes, 0 = No).
How do I do this?
