Nesting TRY...CATCH constructs

You want to register a new buyer in your buyers table. This new buyer is Peter Thomson. His e-mail is [email protected] and his phone number is 555000100.

In your database, there is also a table called errors, in which each error is stored.

You prepare a script that controls possible errors in the insertion of this person's data. It also inserts those errors into the errors table.

How do you prepare the script?
