Join David Gassner for an in-depth discussion in this video Committing and rolling back transactions, part of Java Database Integration with JDBC.
A database transaction is one or more actions that are making changes to data in a database…server or local database file.…Whenever you make changes such as inserts, updates, or deletes, you're creating transactions.…And in JDBC, these transactions are what we call auto-committed.…That is, if you don't see anything else, the changes that you request are made and committed…to the database immediately.…But most database management systems give you the ability to explicitly commit and roll back transactions.…It depends on what database you're using, and how you're using it.…
For example, with MySQL, it depends on what backend database engine you are using.…I'm going to go to phpMyAdmin to my Explore California database, and I'll choose one of…my tables, the admin table, and I'll go to the Operations tab.…Notice that the storage engine for my database tables is innoDB, and I have specifically selected…that because innoDB supports transactions, row-level locking foreign keys, and other advanced database functionality.…
Author David Gassner explains how to choose a JDBC driver and connect to one or more databases. He also provides detailed instructions on reading, selecting, and updating data; calling stored procedures; managing data via JavaBean classes or with prepared statements; and working with metadata.
