DBCC SQL Server 2000 sysindexkeys

I have a SQL Server 2000 database. When I run the following command

select * from sysindexkeys

This display the appropriate records.

I then do a DBCC command for the sysindexkeys. It doesn't display anything. Strange开发者_如何学C there is no page having the sysindexkeys records. Then how the query display the list of records.

Interesting

Paul Randall wrote DBCC and he filtered out (see comment) system tables for some commands... but nothing on his blog
