Hi, Experts:
   I am trying to try the query to go through each table in my database and list its dependencies. (Foregn Keys). Any idea how to do that?

Example:

  tbl_Cars_Info
      CarsTypeID (FK), tbl_Lookup_CarsType (PK Table), CarsTypeID (PK)
      CarsMakeID (FK), tbl_Lookup_CarsMake (PK Table), CarsMakeID (PK)
  tbl_Sales_Info
      SalesTypeID (FK), tbl_Lookup_SalesTypes (PK Table), SalesTypeID (PK)

Group by table names
   List the foreign key of the table, list the table it is depending on, list the primary key of the lookup.


Thanks a lot

I have had the need to do similiar things in the past.  To do it, I use the SQL-DMO objects.  They allow you to manipulate the SQL objects programmatically, including listing out their dependent objects.  It works for related tables, but it also works for other objects too (like if a stored procedure depends on a view).

All the documentation is on MSDN, and I also found this link:

Hope that helps,

Take a look at:
sp_fkeys 'tablename'
sp_pkeys 'tablename'

The proc below loop thru all tables and execute sp_depends, sp_fkeys, sp_pkeys on each table.


Drop Procedure sp_DependencyRep
go


Create Procedure sp_DependencyRep
AS
BEGIN

DECLARE @v_name varchar(30)

DECLARE table_cursor CURSOR FOR
select name from dbo.sysobjects
where type = 'U'

OPEN table_cursor

FETCH NEXT FROM table_cursor
INTO @v_name

WHILE @@FETCH_STATUS = 0
BEGIN

   PRINT @v_name

   EXEC ('sp_depends ' + @v_name )
   EXEC ('sp_fkeys ' + @v_name )
   EXEC ('sp_pkeys ' + @v_name )

   FETCH NEXT FROM table_cursor
   INTO @v_name

END

CLOSE TABLE_CURSOR
DEALLOCATE TABLE_CURSOR

END

go

exec sp_DependencyRep
go

Not sure why you would build some big ellaborate cursor to do a simple task:

select * from INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE


There might be instances where everything isn't returned, but for the most part, everything can be managed using INFORMATION_SCHEMA views.
