Hello,
I am working with a database that is in use in several locations.
The structure of the databases are identical, but the data is
different.
I am tasked with combining the data into one large database.
(It is SQL 2000)
I have .bak files for each location.
Is there any way to restore a backup into a database, combining the
data?
If not, what is the best way to accomplish this?
Thanks,

In a word, no. You should probably restore both databases to a single
machine, and write a script to combine the data.
There are tools to compare the data in the two databases (Like Red
Gate's SQL Data Compare), but AFAIK nothing to combine the data.

Hello,
Thanks, I kinda figured that about the backups.
About writing the script, what is involved in that?
I am pretty good with this one database, but am by no means an expert.
Luckily, the database is the same version, the same structure at each
location.
My thoughts are to add additional blank SQL databases, then populate
them with the bak files.
then combine the databases into one large database.
I understand that a MoveTo is the command, but I have never written one
and have no idea how to start.
Any information would be appreciated.
Am I foolish to hope that since the databases have the same tables and
structure that this will not be very complicated?
Thanks

Yes.
Imagine database A has order no 1, being shipped to customer no 1.
Database B also has an order no 1, being shipped to customer no 1.
But in database A customer no 1 is Mr. Black, in B it is Mr. White.

There is a tool to *compare* data - SQL Server Comparison Tool.

Red Gate's SQL Data Compare will let you syncronize your data.
Assuming that you don't have duplicate keys and so on, you can just use
it to bring across data that is in one database and not in another.
If you do have duplicate keys (and you probably do) you're going to
have to do some analysis. If the keys are identity keys I think Red
Gate's product (and they're reasonably cheap) will give you options to
deal with it. If it's a natural key you'll need to do some updating
(say, Update table2 set key = key + 100000) to ensure integrity.

I need a bullet proof way to combine a root and a relative path to form a FQ
rooted path (similar to a VDir in IIS). Path.Combine alone will not do the
job in all cases. I also need to be sure the no funny business can go on in
the passed "path" that would produce a path not in the root (i.e.
"..\..\dir1"). Here is my first stab at it, but not sure if this is too
much or not enouph to ensure this. Any thoughts are welcome. TIA.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
