usp_dependencytree

,

This procedure shows in a tree structure the dependencies of an object. It's very a basic, but effective script. Script is developed for 2K5

Make sure recursive triggers is enabled!

Also, in order to be sure the metadata in sys.sql_dependencies is actual, run sp_refreshview for views, or sp_refreshsqlmodule for each view/procedure and function

if object_id('usp_dependencytree') is not null
   drop procedure usp_dependencytree
go

create procedure usp_dependencytree(@ObjectName sysname, @deplevel int)
/*

    author:  wilfred van dijk (www.wilfredvandijk.nl)
    purpose: shows dependencytree for specified object
