Recreate dependencies in database

,

This procedure refresh all views of current database in good order to recreate correct dependencies lost after updating views.
This procedure just call sp_refreshview and uses temporary table

Execution of this procedure prevent errors in DTS Import/Export wyzard : Copy objects and data between SQL Server databases

exec refresh_all_views_in_order
-- in current database and all dependencies are ok

I have tested this procedure in SQLSERVER 2000

Create procedure refresh_all_views_in_order
