SQL Insert, w/ ODBC, on a table with no primary key

[chadtimothy23]

I am testing with a paradox table trying to insert user productivity records for my PHP based order-entry module. The developer who developed the main module with Delphi for various reasons has no primary key on the productivity table I am trying to insert records into. Apparently, PHP, or ODBC, or my SQL statement doesn't like that fact. Is there anyway around not having a primary key on a table while doing an insert or update in this situation?

Thanks in advance!

There is no need to have a primary key to insert a data set into a database. An error message might help the search.
