DBCC stood for Database Console Command (Database Consistency Checker prior to SQL2000). It's now divides into four categories: validation, maintenance, informational, and miscellaneous.
To get a list of all the DBCC commands: DBCC help ('?')
To get syntax help with a particular DBCC command: DBCC help ('checkdb')
The Validation commands are the CHECK commands:
The Informational commands are:
DBCC PAGE (you need to turn on trace flag 3604 to see the output. DBCC TRACEON(3604) )
