How can I find out what FOREIGN KEY constraint references a table in SQL Server?


By using the following command in sql server, you are able to find out the foreign key constraint references.

SELECT
   OBJECT_NAME(f.parent_object_id) TableName,
   COL_NAME(fc.parent_object_id,fc.parent_column_id) ColName
FROM
   sys.foreign_keys AS f
INNER JOIN
   sys.foreign_key_columns AS fc
      ON f.OBJECT_ID = fc.constraint_object_id
INNER JOIN
   sys.tables t
      ON t.OBJECT_ID = fc.referenced_object_id
WHERE

   OBJECT_NAME (f.referenced_object_id) = 'YourTableName'
