Question

What sql query would you write to get the table names which have a particular foreign key.

Eg. Person_Table(person_id,name,address,...)
    Purchases_Table(purchaseid, purchased_by_id(fkey)....)
    AccountDetails_Table(AccountId,PersonID,....)
    Roles_Table(PersonId,RoleID)

Now i want to find the table names where Person id is used as a foreign key.
The above schema would return me

Purchases_Table,AccountDetails_Table, Roles_Table

Database: SQL Server

Answer 1

select OBJECT_NAME(fkc.parent_object_id) as TableName
    from sys.foreign_key_columns fkc
        inner join sys.columns c
            on fkc.referenced_object_id = c.object_id
                and fkc.referenced_column_id = c.column_id
    where fkc.referenced_object_id = OBJECT_ID('dbo.Person_Table') 
        and c.name = 'person_id'
