How to I find all tables that have foreign keys that reference particular table.column AND have values for those foreign keys?

Question

I have a table whose primary key is referenced in several other tables as a foreign key. For example:

try this query:

You have to use sysreferences and sysobjects tables to get the information

Query below gives all the foriegn keys as well as parent tables with column names from the database

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'
