netisam vs sql

Is raining outside, now raining season. I get a call from customer, they need to delete an unuse record from the database, for some reason, they just can't remove the record from the application, even their MIS people can't help. It is using a netisam (Sun product) file database. I need to write a program to delete the record. If using sql (any) database, just issue a sql command will do.
