Copy Database Wizard .... Missing!

Background:

Running SQL 7, have to move a database to someone else's server. They are running 2000.

Looks like the easiest way to do this is with the Copy Database Wizard!

Stupid Question 1: My SQL 7 Enterprise Manager doesn't have Copy Database Wizard listed in it's tasks for the server, per the instructions. Any idea why it's not?

Stupid Question 2: Are there any issues with using this procedure (assuming I can get the wizard to show itself) to transfer a 7 database over to 2000?

Many thanks!

Jerrekcopy database wizard is a fancy gui for detaching the db, copying mdf/ndf/ldf over, attaching db on both servers. check sp_detach/attach_db in bol.sqlsql

Coplicated view - picking from a=b or from c&d =e

I realized there was something wrong with my view when an entire line
was missing. I believe it is caused by an inner join I did on one
column to create another column which may not actually have a value.
let me show you.
Table A ViewA ViewB
type1 type1
type2 type2
type3 type3
answer answer
Pretend that any / all items in Table A can be null. What I want the
view to do is either 1) have both viewA and ViewB answer show up even
if its null or 2) try to get viewB answer but if not, then go to ViewA
answer, then null.
Yes, that is a VIEW doing this...or so I hope.
Any ideas?

RocketMan,
Try:
select
coalesce(c.c1, b.c1, a.c1)
from
tableA as a
full outer join
viewA as b
a.c1 = b.c1
full outer join
viewB as c
on a.c1 = c.c1
GO

Adding this to the views ( of other tables) made the join work and I
was able to get the line to appear.

this kind of help
