sql 2005 to Sybase?
Great...
I need a live feed of inserts updates and deletes from a MS SQL 2005 table
to a Sybase table, do you have a general idea how I can accomplish this with
SSIS?
Thx!

to a results table and select the tranaction IDs you want to stop and start
at.

It is possible to programmatically do this.

1st
I'm thinking that:
@.minxact_seqno ,@.maxxact_seqno
should read:
@.xact_seqno_start, @.xact_seqno_end
yes/no?
2nd
so it won't really be transactional replication, it'll be a scheduled job?
3rd
how will the distribution database get cleared of it's transactions, once
they've been applied to the sybase server. what do i use as a subscriber?
4th
I'm familiar with setting up linked servers,
what's the best way to read through the table and apply the transactions?
BTW, Thx a mill for your time and help!

OK, but the naming convention I use implies the maxiumn one last collected
and the current maxiumn. Its all a naming convention - whatever works for
you

It will be transactional replication to a dummy subscriber. You will need to
create some scheduled jobs to read the commands and then replay them on
Sybase.

Create a dummy database - a plain vanilla one on the publisher and
replicated there. Delete rows from it on a schedule to keep it small and
then set your min retention to 6 hours or so, a time interval which will
allow you to collect all the commands. The distribution clean up job will
remove them from the distribution database. But it doesn't know if they have
been applied on Sybase yet, so you will have to make sure you collect them
before they are deleted.

You will have to implement some sort of tracking column. Perhaps an tinyint
or int col with a default of 0, as you apply the command delete it from the
table. You can also create tables for each day or hour and then read them
until all the commands are applied and then drop them.

Your welcome

I've made some progress.
1. I've installed the Sybase drivers
2. I've setup the oledb connection and successfully retrieved data from the
Sybase tables using the linked server.
I've now hit a snag and need your expertise.
The parameters for sp_browsereplcmds are no longer the same.
The @.results_table is no longer a parameter.
What's the alternative in 2005 to accomplish the same thing?
