In this case when you load the damped data it will process tabs properly and will fail any invalid records but finish the process itself. If you redirect output into a separate file you can analyze later how many records failed. May be that's what you need in your case. The only problem with this method I know is that it takes longer to load the data as it does full validation for each record. -- Vladimir Yevdokimov <vladimir@xxxxxxxxx>
