@@Error help

Im not really understanding how @.@.Error works. If I run this code:
exec sp_rename 'Table3','Table1'
select @.@.Error
in a DB with no Table3, I get the error message:
Server: Msg 15225, Level 11, State 1, Procedure sp_rename, Line 273
No item by the name of 'Table3' could be found in the current database
'ZipCode', given that @.itemtype was input as '(null)'.
but @.@.Error is still 0. If Im getting an error message, why is @.@.Error 0?
TIA,
ChrisRrun this for fun
create table blah (id int)
declare @.id int
EXEC @.id =sp_rename 'blah', 'blah2'
select @.id
--@.id = 0
--run again
declare @.id int
EXEC @.id =sp_rename 'blah', 'blah2'
select @.id
--@.id = 1
So it looks like it returns 0 when there is no error

I was just giving you the code so that you could test what the proc
returns
If you run this, the @.id should be 1 (or better not 0)
declare @.id int
exec sp_rename 'Table3','Table1'
select @.id|||Certain types of errors are not trapped by @.@.ERROR, or the new TRY...CATCH
in SQL Server 2005. Basically, things like syntax errors or invalid object
references can prevent the batch from being successfully compiled and
executed. @.@.ERROR and TRY...CATCH only get invoked if the batch was
successfully compiled and executed. So errors like a WHERE clause that
references and invalid key value or something that does a divide by zero
will generate errors during the execution of the batch that can be processed
by @.@.ERROR or TRY...CATCH. A typo like writing SEELCT instead of SELECT
prevents the batch from being compiled, so the Database Engine simply
returns the syntax error to the calling application.
