Restoring DBs as different names for testing

Good morning,
There is a job that runs daily to restore the production databases to a
different server for testing purposes so that the test site can have live
data on a daily basis. There is a script that runs after the database
restore to ensure views/procedures/triggers are not referencing the
production REPORTING server... however it errors out everyday. As I did not
build this job and the old DBA left months ago... I'm stumped as to how I
can resolve this.
The script is below... cphprod is the restored database (the prod db is
cph...) The error I receive everyday is: Error string: The column prefix
'cphprod' does not match with a table name or alias name used in the query.
Error source: Microsoft OLE DB Provider for SQL Server Help file:
Help context: 0 Error Detail Records: Error: -2147217900
(80040E14); Provider Error: 107 (6B) ...
Any idea how I can work around and/or resolve this?
Does anyone have a better way to change all references to a prod reporting
environment?
Thanks in advance for your help...

-->> There is a script that runs after the database restore to ensure
I could be wrong here, but are you updating the system tables here? Can you
explain what logic is being employed here?
On a cursory glance, I see some meaningless statements like "set @.char10 =
@.char10" and excessive usage of TOP clauses in your script.
The error message suggests that you are trying to use a table name/alias
which is already replaced in the FROM clause, but still exists in some other
section of a stored procedure, view or function. Without a detailed
inspection of the code and test it out, it is hard to spot out which
procedure, view or function is the real culprint here.
