Stored Routine Syntax


Appendix D. System, Status, and User Variable Reference

This appendix describes several types of MySQL variables:

  • System variables that provide information about server configuration

  • System variables that exist in session-only form per client

  • Status variables that provide information about the server's current operational state

  • User variables that you can define, assign values to, and refer to in expressions

Values for variables that represent buffer sizes or lengths generally are given in bytes. Exceptions are noted as necessary.

Unless otherwise indicated, the variables listed here have been present in MySQL at least as early as MySQL 4.1.0. Variables that were introduced or that changed in meaning since then are noted.
