Question

I can get the columns of a table in sql server using this query:

  select * from information_schema.columns where table_name = 'MyTable'

but How do I find the foreign key columns associated with that table?

Answer 1

It’s inside information_schema.table_constraints.

EDIT:

Wait, I think information_schema.key_column_usage is better:

select * from information_schema.key_column_usage where table_name = '...'

And then if you need to make sure that it is really a foreign key, query table_constraints using the constraint name that you got from above:

select * from information_schema.table_constraints where constraint_name = '...'
