Question : truncate all user table in one script sqlserver 2000

Hi experts, I need a script to truncate all user tables. They have asked me to copy the prodcution db to a test server but they want it empty. To be able to do that I need a script that combines the finding of the tables that are being referenced and the truncate of the tables. We are using sqlserver 2000. I have found this script on the web to get tables that are being referenced or not in a database.
declare @r table (
PK_TABLE nvarchar(200),
FK_TABLE nvarchar(200),
primary key clustered (PK_TABLE,FK_TABLE))

declare @rs table (
PK_TABLE nvarchar(200),
FK_TABLE nvarchar(200),
primary key clustered (PK_TABLE,FK_TABLE))

declare @t table (
REF_LEVEL int,
TABLE_NAME nvarchar(200) not null primary key clustered )

declare @table table (
TABLE_NAME nvarchar(200) not null primary key clustered )
set nocount off

print 'Load tables for database '+db_name()

insert into @table
select
      TABLE_NAME = a.TABLE_SCHEMA+'.'+a.TABLE_NAME
from
      INFORMATION_SCHEMA.TABLES a
where
      a.TABLE_TYPE = 'BASE TABLE'      and
      a.TABLE_SCHEMA+'.'+a.TABLE_NAME <> 'dbo.dtproperties'
order by
      1

print 'Load PK/FK references'
insert into @r
select      distinct
      PK_TABLE =
      b.TABLE_SCHEMA+'.'+b.TABLE_NAME,
      FK_TABLE =
      c.TABLE_SCHEMA+'.'+c.TABLE_NAME
from
      INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS a
      join
      INFORMATION_SCHEMA.TABLE_CONSTRAINTS b

      begin
      set @level = @level + 1

      print 'Delete lower level references'
      delete from @r

      insert into @t

Answer : truncate all user table in one script sqlserver 2000

Yes Microsoft is Right.

When it comes to Outlook 2003 we will need to manually Reconfigure the Profile if Outlook 2003 is not able to Connect to the Mailbox after the Migration.

There are tools like Outlook Profile Update Tool but it does not work with Exchange 2010.
