MySQL Server supports a HELP statement that returns online information from the MySQL Reference manual (see Section 12.3.3, “HELP Syntax”). The proper operation of this statement requires that the help tables in the mysql database be initialized with help topic information, which is done by processing the contents of the fill_help_tables.sql script.

For a MySQL binary distribution on Unix, help table setup occurs when you run mysql_install_db. For an RPM distribution on Linux or binary distribution on Windows, help table setup occurs as part of the MySQL installation process.

For a MySQL source distribution, you can find the fill_help_tables.sql file in the scripts directory. To load the file manually, make sure that you have initialized the mysql database by running mysql_install_db, and then process the file with the mysql client as follows:

shell> mysql -u root mysql < fill_help_tables.sql

If you are working with Bazaar and a MySQL development source tree, the tree doesn't contain fill_help_tables.sql. You can download the proper file for your version of MySQL from http://dev.mysql.com/doc/. After downloading and uncompressing the file, process it with mysql as just described.
