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).

Read the question again. It is in English <g>.
"The creative process is nothing but a series of crises." Isaac Bashevis Singer
"My experience is that as soon as people are old enough to know better, they don't know anything at all." Oscar Wilde
"If a nation values anything more than freedom, it will lose its freedom; and the irony of it is that if it is comfort or money that it values more, it will lose that too." W.Somerset Maugham
