versuchen Sie diese Abfrage:
Sie müssen sysreferences verwenden und sysobjects Tabellen, um die Informationen zu erhalten
Die folgende Abfrage gibt alle Fremdschlüssel sowie übergeordnete Tabellen mit Spaltennamen aus der Datenbank aus
select cast(f.name as varchar(255)) as foreign_key_name
, cast(c.name as varchar(255)) as foreign_table
, cast(fc.name as varchar(255)) as foreign_column
, cast(p.name as varchar(255)) as parent_table
, cast(rc.name as varchar(255)) as parent_column
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
where f.type = 'F'
