Since this is VFP table and you want to clean it, for this particular case don't use CA, ZAP the table, then you can work with CA.

I can fill the CA cursor with all records, delete records, and then call tableupdate(). But my questions is, how practical this approach if the table can have up to (max) 10,000 records. This is a VFP database (not SQL Server).
If it's not broken, fix it until it is.
