mysql_upgrade(1)

NAME

       mysql_upgrade - check tables for MySQL upgrade

SYNOPSIS

       mysql_upgrade [options]

DESCRIPTION

       mysql_upgrade should be executed each time you upgrade
       MySQL. It checks all tables in all databases for
       incompatibilities with the current version of MySQL
       Server. If a table is found to have a possible
       incompatibility, it is checked. If any problems are found,
       the table is repaired.  mysql_upgrade also upgrades the
       system tables so that you can take advantage of new
       privileges or capabilities that might have been added.

       All checked and repaired tables are marked with the
       current MySQL version number. This ensures that next time
       you run mysql_upgrade with the same version of the server,
       it can tell whether there is any need to check or repair
       the table again.

       mysql_upgrade also saves the MySQL version number in a
       file named mysql_upgrade.info in the data directory. This
       is used to quickly check if all tables have been checked
       for this release so that table-checking can be skipped. To
       ignore this file, use the --force option.

       To check and repair tables and to upgrade the system
       tables, mysql_upgrade executes the following commands:

       mysqlcheck --check-upgrade --all-databases --auto-repair
       mysql_fix_privilege_tables

       mysql_upgrade currently works only on Unix. On Windows,
       you can execute the mysqlcheck command manually, and then
       upgrade your system tables as described in
       mysql_fix_privilege_tables(1).

       For details about what is checked, see the description of
       the FOR UPGRADE option of the CHECK TABLE statement (see
       Section 5.2.3, "CHECK TABLE Syntax").

       To use mysql_upgrade, make sure that the server is
       running, and then invoke it like this:

       shell> mysql_upgrade [options]

       mysql_upgrade reads options from the command line and
       fromm the [mysqld] and [mysql_upgrade] groups in option
       files. It supports the following options:

       o  --basedir=path

          The path to the MySQL installation directory.

       o  --datadir=path

          The path to the data directory.

       o  --force

          Force execution of mysqlcheck even if mysql_upgrade has
          already been executed for the current version of MySQL.
          (In other words, this option causes the
          mysql_upgrade.info file to be ignored.)

       o  --user=user_name, -u user_name

          The MySQL username to use when connecting to the
          server. The default username is root.

       o  --verbose

          Verbose mode. Print more information about what the
          program does.

       Other options are passed to mysqlcheck and to
       mysql_fix_privilege_tables. For example, it might be
       necessary to specify the --password[=password] option.

       mysql_upgrade was added in MySQL 5.0.19. It supersedes the
       older mysql_fix_privilege_tables script.
