TSQLTransaction is a non-visual component that intermediates between a database connection such as TSQLConnection and a TDataSet-derivative like a TSQLQuery.
A TSQLTransaction is used to guard a series of queries such that either all of the queries are executed by a Commit() or none using Rollback().
SQLTransaction1.Database := SQLConnection1; SQLQuery1.Transaction := SQLTransaction1;
