| I'm having difficulty searching for an answer to this challenge. Can someone give me a clue on the right keywords to use to find a discussion on this subject? All of the ones I saw appear to touch on older versions. I'm working with SQL Server 2000, and need to backup and restore only tables, because the full backup/restore appears to mess up users/security, or something or another. Thanks for the assist. |

You backup and restore an entire database. Unless you're using filegroups, etc. However, most likely what you need is sp_change_users_login to reconcile the users in the database with the logins on the server. Check that out. It will most likely solve your problems. > > Thanks for the assist. > |

You cannot backup and restore individual tables. SQL 6.5 had such a feature, but thankfully this folly was dropped. You can however backup and restore single filegroups. But it is not likely to be the solution to your problem. BACKUP/RESTORE as such does not mess up users, but if you restore a backup on a different server, you lose the mapping between database users and server logins. Obviously - the logins in two servers are likely to be different. As Greg said, user sp_change_users_login to sort out the situation. -- Erland Sommarskog, SQL Server MVP, esquel@sommarskog.se Books Online for SQL Server 2005 at http://www.microsoft.com/technet/pro...ads/books.mspx Books Online for SQL Server 2000 at http://www.microsoft.com/sql/prodinf...ons/books.mspx |

| There are two requirements here, the first being the need to restore tables to a different server than the backup originated from without messing up mapping of server logins. The second is the need for a user to work remotely on one single table without implementing fancy database features, such as replication. Why not? Because the DBA is a real "P.I.T.A.", and there's no way to convince him he's wrong! I did discover one script to "generate INSERT statements from the existing data" (found here: http://vyaskn.tripod.com/code.htm#inserts). However, this one doesn't work well with tables with many columns, and my table is definitely a "many-columned" table. If someone has experience with fixing this script to be more flexible and suit my needs, I could use it to have the remote user modify records in the table and have the insert scripts generated from this code. Thanks again for further advice.

| Since you rule out the traditional methods for BACKUP/RESTORE, then maybe you can take a look at linked servers (that is if you have direct connectivity between the two servers, which I assume you do because you mention replication). You can set up a remote linked server and then directly query and transfer the tables that you need. It can be easily automated via a stored procedure that can be scheduled to run as a job. Simple enough. Not the fastest approach but seems you are already looking at generating INSERT statements to dump the data out... Another alternative is to use a DTS package to transfer the tables. It can be also fully automated, but assumes as above that you have connectivity between the servers. If you do not have direct connectivity then you can use a similar approach to dumping with INSERT statements, but via DTS. In essence in the source server you can create a DTS task to dump the table data to a text file, then on the destination server import the data to a table using the reverse process. The same scenario is doable using the BCP utility. HTH, Plamen Ratchev http://www.SQLStudio.com |

| Plamen: Thanks for the interesting advice. I am going to try and get direct connectivity to the target server. If I can, the copy tables DTS function is nice and straightforward. I don't know if the BCP utility has been tried, but I'll give that a shot as well. Thanks also to Erland Sommarskog for all your great advice. I'll be experimenting with options for a few days. Thanks again.
