Is an extra record identity column added before the actual columns?
DataFlex Pervasive.SQL Driver
When set to a non-zero value, this indicates that the table is converted from DataFlex with Recnum support. A table with Recnum supports has the Recnum values of the original DataFlex table preserved. Refer to Recnum Tables for further information.
None
You will only need to convert with Recnum support if the Recnum values have some meaningful value. For example when the Recnum value is used as the customer id number in a customer file. Also if you have defined relations from or to the Recnum field, you must use Recnum support. In general Recnum support will only be necessary with applications that are derived from legacy DataFlex character mode applications.
