Hello,

I am trying to truncate data from one server to the other (remote server)

it works from query analyzer like this:

exec RemoteServerName.DatabaseName.DBO.sp_executesql "truncate table DBO.tablename"

it does NOT work from query analyzer like this:

Declare @cmd varchar(2000)
set @cmd = @servername + '.' + @databasename + '_Archive'+ '.' + @schema + '.' + 'sp_executesql' + ' ' + '"' +'truncate table' + ' ' + @schema + '.' + @tablename + '"'
exec xp_cmdshell @cmd

Produced this error:

'RemoteServerName.DatabaseName.DBO.sp_executesql' is not recognized as an internal or external command,
operable program or batch file.

Please Help !

I had to use DELETE as I could not get TRUNCATE to work.

change
exec xp_cmdshell @cmd
to
exec @cmd


Although it looks like it works, double quotes (") are used for quoted-identifiers not for string delemiters. So you should change to sinble quoes (') and preface it with an N for unicode:
exec RemoteServerName.DatabaseName.DBO.sp_executesql N'truncate table DBO.tablename'

I ran exactly you mentioned and got this error

The RemoteServerName.DatabaseName.DBO.sp_executesql N'truncate table DBO.tablename' is not a valid identifier

where's the exec?
try like

Declare @cmd varchar(2000)
set @cmd = 'EXEC ' + @servername + '.' + @databasename + '_Archive'+ '.' + @schema + '.' + 'sp_executesql @statement= N''truncate table '  + @schema + '.' + @tablename + ''''
exec (@cmd)
