# How can we get “MySQL server-side help”?

MySQL provides help command to get server-side help. The syntax of this command is as follows −

mysql> help search_string

MySQL uses the argument of help command as the search string for accessing the contents of MySQL reference manual. The search will fail if there would be no match for the search string.

For example − suppose I want to get server-side help regarding INTEGER data type then the command for the same would be as follows −

mysql> help INTEGER
Name: 'INTEGER'
Description:
INTEGER[(M)] [UNSIGNED] [ZEROFILL]

This type is a synonym for INT.
