Get all tables where a primary key is linked to a foreign key

Question

Can I retrieve all the table names and the associated column names where a primary key is linked to a foreign key in another table?

Eg: I have a table EMPLOYEE and its primary key is linked to by a foreign key in many other tables, say DEPT , ACCOUNT and so on.

Is there a way that I can can get the table and column names of those tables where I have used employee's Primary key as a Foreign Key?

Answer 1

You could use the "View Dependencies" feature for the primary-table to get that info, in the SSMS. Also there some tools available that help you do that, one such in "SQLSpec". It's a pretty good tool for database documentation.

Hope this helps.

Answer 2

by chance today i got the same query in my mind and using google i found the following sql

SELECT OBJECT_NAME(OBJECT_ID) AS NameofConstraint,
SCHEMA_NAME(schema_id) AS SchemaName,
OBJECT_NAME(parent_object_id) AS TableName,
type_desc AS ConstraintType
FROM sys.objects
WHERE type_desc LIKE '%CONSTRAINT'

you can update the LIKE '%CONSTRAINT' as per your need.

i use this in sqlserver2005
