Symptoms

You cannot use the Database Editor to insert, edit, or delete records in a Paradox database when the records have been accessed through the Database Interface Wizard.

↑ Back to the top

Cause

A table cannot be updated by the Paradox ODBC driver when a unique index is not defined on the table. This is not true for an empty table, which can be updated with a single row even if a unique index is not defined on the table.

If a single row is inserted in an empty table that does not have a unique index, a program cannot create a unique index or insert additional data after the single row has been inserted.

Workaround

To work around this issue, create a unique index for the Paradox table that you want to edit. In order to do this, you may need to obtain the Borland Database Engine.
