Conclusion
In this chapter we took a quick look at the built-in functions that you can use in your stored programs. In general, these are the same functions that you can use in standard MySQL. The only exception is that you cannot use aggregate functions that might be used in SQL statements that include a GROUP_BY clause.
We did not want to bulk up this book with verbose descriptions of every single function supported by MySQL. For functions not listedor for those that received only cursory treatment in this chapterrefer to the MySQL Reference Manual available online (http://dev.mysql.com/doc/ ).
