Displays help information from the server's help tables. Useful for looking up SQL syntax and command descriptions directly from the client.
HELP search_stringThe HELP command can be used in any MariaDB client, such as the command-line client, to get basic syntax help and a short description for most commands and functions.
If you provide an argument to the HELP command, the client uses it as a search string to access server-side help. The proper operation of this command requires that the help tables in the mysql database be initialized with help topic information.
If there is no match for the search string, the search fails. Use HELP contents to see a list of the help categories:
If a search string matches multiple items, MariaDB shows a list of matching topics:
Then you can enter a topic as the search string to see the help entry for that topic.
The help is provided with the MariaDB server and makes use of four help tables found in the mysql database: , , and . These tables are populated by the or fill_help_table.sql scripts.
