Get list of all foreign keys in SQL database

Hello friends,

Yesterday in free time I was just googling for a solution if I can get a single list of all foreign keys defined in my Microsoft SQL database. I found many articles and answers on stack-overflow, too.

Finally after compiling all those solutions I have created my own SQL script. So sharing the with you here with a hope that this may help someone.

SELECT
 FK_Table = FK.TABLE_NAME,
 FK_Column = CU.COLUMN_NAME,
 PK_Table = PK.TABLE_NAME,
 PK_Column = PT.COLUMN_NAME,
 Constraint_Name = C.CONSTRAINT_NAME
FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS C
INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS FK
 ON C.CONSTRAINT_NAME = FK.CONSTRAINT_NAME
INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS PK
 ON C.UNIQUE_CONSTRAINT_NAME = PK.CONSTRAINT_NAME
INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE CU
 ON C.CONSTRAINT_NAME = CU.CONSTRAINT_NAME
INNER JOIN (
   SELECT i1.TABLE_NAME, i2.COLUMN_NAME
   FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS i1
   INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE i2
    ON i1.CONSTRAINT_NAME = i2.CONSTRAINT_NAME
   WHERE i1.CONSTRAINT_TYPE = 'PRIMARY KEY') PT
  ON PT.TABLE_NAME = PK.TABLE_NAME
-- optional:
ORDER BY 1,2,3,4
