PRB: Cannot Reuse Deleted Primary Key Values in Visual FoxPro

MORE INFORMATION

To create a filtered index so that you can reuse deleted keys, enter the following expression for the primary key Filter:

   !DELETED()
					

Now a deleted key can be reused in another record in the table. Although the setting of DELETED has no effect on the error, you may want to set DELETED ON, so that deleted records are not displayed.

NOTE: If the !DELETED() filter is placed on a primary key, then Gendbc.prg is used to create a program to rebuild the .Dbc, the resulting primary key will not have the filter expression.
