There is a stored proc in DB1 (SQL 2000) that deletes and inserts into a table in another database (DB2) in the same server.

But now the other database (DB2) had to be moved to another SQL 2008 server and henee linked server was created.

but now the sp fails.. because LS only reads.. no other permissions..

i thoughts about 'execute as', but that is not available in sql 2000..

what would recommend as the best practise to just give just enough permission to be able to do the del/insert into the other database.

Seems like a permission issue to me, you can try creating the linked server using a the SQL login which has permission to delete on SQL 2008 Server.

thanks.. i find that the linked server login did not have those permission..

now, i have a touble with this solution..

the linked server (destination) DB2 is being linked to many servers including DB1.. all the servers use the same readonly login (DataConnect_Login) to the DB2 database. Only this proc in one app needs more than read..

do you have any suggestion to keep this clean (in the above scenario)..

If DataConnect_Login is given update and delete on this login for this proc, then all servers have update/del permission on this table.. rather only DB1 needs this feature. (the idea is not to give DataConnect_Login more than read, but also keep it simple.. I am open to ideas.. if there is no other way, then will revert to the first option)

Is there any out of the box idea  beside the above?

thanks

SPN will be your best shot, if you setup the SPNs you dont have to specify explicit SQL logins
Google for SQL SPN, its pretty simple to setup
