Question

I wrote this code trying to know the relations amongs other tables from my BD but it didn´t bring nothing.

 

USE tuBaseDeDatos; 

GO  DECLARE @tabName AS Varchar(50) 

SET @tabName = 'dbo.TU_TABLA'--table´s name from fk´s are goint to get 

 SELECT OBJECT_NAME(f.constid) AS 'FKName', c.name AS 'ColName'

 FROM sysforeignkeys f INNER JOIN syscolumns c 

ON f.fkeyid = c.id AND f.fkey = c.colid

 WHERE fkeyid = OBJECT_ID(@tabName)
