Phantom user issue?

Let me modify this...whichever side I control is the side that has the
DTS. It could be that I controlled the side being published too, in
that case, it becomes a pull transaction instead of a push.

Yeah...just schedule the DTS, and you never have to touch it again,
and modifying it is point and click.

It would definitely be possible to do this by disconnecting the
detaching the db and uploading and reattaching, or by uploading a
backup, or even uploading a flat file and importing it, or some other way,
but all those adds steps, and possible points of failure. None are
totally unacceptable, they just wouldn't be my choice.

Other than importing a flat file, the other two have downsides as
well. Like the phantom user issue...

Wow, well said; thank you for taking the time to help me understand this. I
always thought DTS was used to migrate databases, or transfer data between
disparate data sources. I didn't realize it was useful for making small
batch updates.

I had already run into the schema problem you mentioned with replication
since my primary keys are identities.

But why don't you recommend FTPing the updated database files? Is that some
kind of SQL Server no-no? If so, why?

Re: DTS to update SQL Server database?

2003-06-11 Thread jon hall
I've found out the best way is usually determined by the
circumstances. How much does a client want to pay...how technical is
the other side, do you want realtime, pseudo-realtime, or batched
updates, firewalls, etc.

In my perfect world though, in a batch situation, with a small update,
the publishing side would fire a DTS that connected to the remote side
and updated the data. This one takes very little time to setup, and
doesn't place the constraints that replication does on the schema. It
also can be done manually or automated, so it's flexible.

DTS to update SQL Server database?

2003-06-11 Thread Dina Hess
Hi all,

Can someone explain? Is it better to use DTS, replication, or FTP to update
SQL Server 2K database files on a shared host? (The database is small; there
will only be about 50 new records each week.)

TIA,
~Dina
