DBCC means DataBase Consistency Checker
The Issue: Get a list of all the DBCC commands both documented and undocumented.
They're not all documented but at leas you can get the syntax.
Solution: Turn on trace 2520 and use DBCC HELP ('?') to get a list of all the commands.
The script:
dbcc traceon(2520)
dbcc help ('?')
GO
dbcc traceon(2520)
dbcc help ('?')
GO
Shows the list of DBCC commands. then
DBCC HELP(
Shows the syntax of an individual co
DBCC HELP(
Shows the syntax of an individual co
If you run DBCC HELP on all the commands you end up with this list:
DBCC activecursors [(spid)]
