MySQL Server supports a
statement that returns information from the MySQL Reference Manual
(see Section 13.8.3, “HELP Statement”). This information is stored in
several tables in the
mysql schema (see
Section 5.3, “The mysql System Schema”). Proper operation of the
HELP statement requires that these
help tables be initialized.
For a new installation of MySQL using a binary or source distribution on Unix, help-table content initialization occurs when you initialize the data directory (see Section 2.9.1, “Initializing the Data Directory”). For an RPM distribution on Linux or binary distribution on Windows, content initialization occurs as part of the MySQL installation process.
For a MySQL upgrade using a binary distribution, help-table
content is upgraded automatically by the server. To upgrade it
manually, locate the
file in the
share/mysql directory. Change location into
that directory and process the file with the
mysql client as follows:
mysql -u root -p mysql < fill_help_tables.sql
The command shown here assumes that you connect to the server
using an account such as
root that has
privileges for modifying tables in the
schema. Adjust the connection parameters as required.
