MySQL SubQueries

Color Highlights

When you look at SQL statements and functions on the pages for some sections of our documentation for MySQL, you may notice that some are shown in a different color (light blue at the moment). What we've done is set up a log to keep track of which pages of our documentation readers view. From there, our script every few minutes determines the most popular statements and functions and changes the colors of the links to those pages.

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.
