sql table record copy

MS SQL Server 2008

How do you script via a Stored Procedure the following:

DB 1 - Table 1A (server A)
DB 2 - Table 2A (server B)

if   DB 1 - Table 1A (column1) - unique value (uniqueidentity) doe not exist in
DB 2 - Table 2A (column1) - unique value (uniqueidentity) then create it in  DB 2 - Table 2A

then copy certain columns from DB 1 - Table 1A to DB 2 - Table 2A (insert a new entry).

(there could for example none, 1 or 1000's of new table entries to create/insert each time stored procedure is called)

first create a linked server to serverA from ServerB lest name the linked server as "lsserverA"
then run the following query... This will populate B with the values exists in A but not in B

INSERT INTO DB2..Table2A
SELECT *
FROM lsserverA.DB1..Table1A  A
      LEFT JOIN DB2..Table2A B ON A.column1 = B.column1
WHERE B.column1 IS NULL

you can put this code in a procedure and call it again and again..

you can create a linked server like the one below

EXEC sp_addlinkedserver  
   @server='lsserverA',
   @srvproduct='',
   @provider='SQLNCLI',
   @datasrc='Server1.abc.com\DB1'

tigin44:  does it matter which db server to run that script?   is this link preserved upon a physical reboot of server?

I assume that you will run this code on ServerB ... you can run it vice versa but you should change the linked server and references to the new definitions to run it on ServerA...
