# mysql.help\_relation Table

`mysql.help_relation` is one of the four tables used by the [HELP command](../../sql-statements/administrative-sql-statements/help-command). It is populated when the server is installed by the `fill_help_tables.sql` script. The other help tables are [help\_topic](mysql-help_topic-table), [help\_category](mysql-help_category-table) and [help\_keyword](mysql-help_keyword-table).

This table uses the [Aria](../../../server-usage/storage-engines/aria) storage engine.

The `mysql.help_relation` table contains the following fields:

| Field             | Type             | Null | Key | Default | Description |
| ----------------- | ---------------- | ---- | --- | ------- | ----------- |
| help\_topic\_id   | int(10) unsigned | NO   | PRI | NULL    |             |
| help\_keyword\_id | int(10) unsigned | NO   | PRI | NULL    |             |
