This document contains the code for several stored procedures used in a library database. The procedures handle tasks like adding new adult and juvenile members, checking books in and out, getting member and book information, and updating member expiration dates. Validation checks are performed on parameters and data is inserted, updated, and selected from relevant tables within transactions.
