Relation to dbid in sysdatabases

What if i update a dbid from 14 to 24 say for example, is there a reference
to it in any system tables in the corresponding user database itself that i
would also need to update. Just curious.
Will the db go into suspect mode or will it just continue to function as
normal ?I don't think there are references in the database itself to the dbid, but
there are plenty of references in master to the database id, including in
sysxlogins, which you also asked about. Some of the tables are
pseudo-tables, so they would probably be fine, but many are real tables what
could be corrupted if you updated a dbid.
I have never done this, so I can't tell you for sure what might break.
This query will show you all the columns in tables in master that reference
dbid:
use master
select name, object_name(id), objectproperty(id, 'tableisfake') from
syscolumns where name = 'dbid'

I've never tried this, a lot of the system uses the database name as it's
key, so maybe you would get away without breaking too much
......but any update to system tables is unsupported..........
Why would you want to do this ?
