MS SQL Server - Wer verwendet welche Foreign Keys?

Dank der Hilfe von folgendem Blog, habe ich heraus gefunden, wie man eine Übersicht darüber ermitteln kann, welche Tabellen, welche Foreign Keys nutzen: http://bytestopshere.wordpress.com/2008/11/01/sql-server-script-to-find-foreign-key-dependencies/

Geben Sie einfach folgenden Befehl in das Abfragefenster im SQL Server Managemenet Studio ein und klicken Sie auf "Ausführen":

select cast(f.name  as varchar(255)) as foreign_key_name

    , r.keycnt

    , cast(c.name as  varchar(255)) as foreign_table

    , cast(fc.name as varchar(255)) as  foreign_column_1

    , cast(fc2.name as varchar(255)) as foreign_column_2

    ,  cast(p.name as varchar(255)) as primary_table

    , cast(rc.name as varchar(255))  as primary_column_1

    , cast(rc2.name as varchar(255)) as  primary_column_2

    from sysobjects f

    inner join sysobjects c on  f.parent_obj = c.id

    inner join sysreferences r on f.id =  r.constid

    inner join sysobjects p on r.rkeyid = p.id

    inner  join syscolumns rc on r.rkeyid = rc.id and r.rkey1 = rc.colid

    inner  join syscolumns fc on r.fkeyid = fc.id and r.fkey1 = fc.colid

    left join  syscolumns rc2 on r.rkeyid = rc2.id and r.rkey2 = rc.colid

    left join  syscolumns fc2 on r.fkeyid = fc2.id and r.fkey2 = fc.colid

    where f.type =  'F'

 ORDER BY cast(p.name as varchar(255))
