Adrien,
Thanks for your reply. I am able to execute the query "SELECT * FROM tblparcel_numbers WHERE tblparcel_numbers.Key <> '200';" using MySQL Worrkbench. The query returns the expected data with no errors. So I think that the datafile is OK. This is about 1% of a very large project. It will take some time for me to write a test project and the data in the file is confidential. If a form containing two datasources and a listing of the tblparcel_numbers structure is all that is needed I think I can put that together in a couple of days.
