Sometimes it may be useful to reuse the result of the DBCC commands. If the DBCC command resturns a resultset, it can be outputted to a table. 

Consider the following command

DBCC useroptions

It returns a single resultset. To copy the resultset to a table, you can use the following 

Create table #dbcc_useroptions ([set option] varchar(100), [value] varchar(100))

insert into #dbcc_useroptions 
exec('DBCC useroptions')

select * from #dbcc_useroptions 

drop table #dbcc_useroptions 

Note that it is possible with dynamically executing DBCC commands and only the DBCC commands that return a resultset can be used
