No unique key defined for table table_name.

Situation

You've attempted to use the SQL database type to open a Btrieve or c-tree Plus table that doesn't have a non-modifiable key. When a Btrieve or c-tree Plus table is converted to or opened as a SQL table, the first key for which the Modifiable key option isn't selected is used as the primary key for the table.

Solution

Return to Dexterity and open the Table Definition window for the named table.
