Copying a table across linked servers

This procedure will copy a table across linked servers, overwriting the destination table. It is a time-saver in mixed server development, and is especially useful in keeping development data in sync with production data in remote servers. To use it, compile the procedure std_synctable and run it with the following arguments:

source server name, 
source database name, 
source table name, 
destination table name, 
remote sqluser name, 
remote sqlpassword 

Note: if the remote server has not been registered, either do it from the Enterprise Manager or uncomment the related code in the procedure and execute it once (see Note 1 in code).

                
CREATE PROCEDURE dbo.std_synctable 

@source_server varchar(50), 
@source_database varchar(50), 
@source_table varchar(50), 
@dest_table varchar(100), 
@sqluser varchar(30), 
@sqlpassword varchar(30)

BEGIN 
declare @db varchar(50)

EXEC ("sp_dboption " + @db + ", 'ANSI_NULLS', 'TRUE'") 
EXEC ("sp_dboption " + @db + ", 'ANSI_WARNINGS', 'TRUE'")

--Copies a table from a remote server 
--Arguments are: 
--source server, source database, source table, 
--destination table, userid, userpassword 
--(from the remote server) 
--Note 1: 
--If the remote server has not been added as a linked server, 
--run this once:

--   @srvproduct = 'SQL Server', 
--   @provider = 'MSDASQL', 
--   @provstr = 'DRIVER={SQL Server};SERVER=SERVERNAME;

--now connect as the linked server user 
--EXEC sp_addlinkedsrvlogin @source_server, 'false', NULL,

declare @sql varchar(500) 
declare @source varchar(200) 
select @source = '[' + @source_server + '].'
