DBCC HELP is the first DBCC command we will cover because it can be used to get details on other DBCC commands.
DBCC HELP is a database console command (DBCC) in Microsoft SQL Server that can be used to display a list of all available DBCC commands, or to display detailed information about a specific DBCC command. Displaying a list of DBCC commands or detailed information about a specific command can be useful for learning about the available DBCC commands and understanding how to use them.
To use DBCC HELP, you can either specify the name of a specific DBCC command without the DBCC prefix that you want to display information about, or you can execute the command with a ? as the argument to display a list of all available DBCC commands.
Here is an example of how to use DBCC HELP to display a list of all available DBCC commands:
-- Display a list of all available DBCC commands
dbcc help ('?')
The output of DBCC HELP will be a list of all available DBCC commands.
Here is an example of how to use DBCC HELP to display detailed information about a specific DBCC command:
-- Display detailed information about the DBCC CHECKDB command
DBCC HELP ('CHECKDB');
The output of DBCC HELP for a specific DBCC command will include a description of the command, a list of any arguments the command accepts, and information about any options or flags that can be used with the command.
DBCC HELP is a useful tool for learning about and understanding the available DBCC commands in SQL Server. It can be used to display a list of all available DBCC commands or detailed information about a specific DBCC command.
