Need Math Examples
Although we did well in math classes all through school, we have very little experience with the Math Functions of MySQL very little. As a result, we don't have very good examples for them. If you work in science or engineering and have some ideas for easy to understand examples that we can add, please tell us.
MySQL Replication

Whether you’re new to MySQL replication or have been using it for some time, you will find this new book useful. It will help you actually to understand MySQL replication so you can keep it running. It’s especially useful when replication stops and you can’t get it started again.
