    Unanswered: daily transfer from oracle schema to similar SQL-Server

    I have some small (<5000 records) Oracle tables that I need to transfer daily to SQL-Server.


    The old legacy standalone Oracle system here in Hong Kong must still be used to enter property data, so I cannot change it. The idea is to get this data in every day into an SQL-Server. I am sure they can be connected over the company's LAN if not so already. The aim is to then put together a basic front-end for this data. Both systems although fairly similar (property web site data), their schemas are fixed and the SQL-Server schema is in use by another branch of the company for a U.K. property site. The Hong Kong team want me to get their legacy data in to this new system every day and then do a similar web site for their HK data.

    Is there a way where I can, say automate DTS to run every day on the SQL-Server machine, get the Oracle tables over the LAN to SQL-Server, then write scheduled stored procedures that massage the data from one schema to the other (I will have to lose a bit of data, since they are not exactly the same tables and fields, though with property data, it is all pretty much the same).

    I once did this using ASP (after getting the data into a CSV file from an ACCESS database). The script looped through each line of data and put it into the relevant table.

    Anyone got any ideas? Much appreciated. I

    try using a linked server to transfer the data from the oracle server. It is much more faster . Write a stored procedure for the same and then schedule it as a job

    Thanks. I will meet their IT admin guy next week. So, I will have an Oracle DB and a SQL-Server DB. I am familiar with Enterprise manager, I can add remote SQL-Server groups. How would I go about setting up a 'Link Server'. In my main job, we use Lotus Enterprise Integrator (LEI), a handy tool that transfers data from Lotus Notes to anything else, but not sure of a tool for my needs.

    I'm more from a programming background. Can you explain the Link Server setup. The scheduled SP's I've done before.

    Many Thanks

    You can look in books online and search for "linked server". Also, in the enterprise manager under the security directory are the linked servers visible.

    Thanks guys, I've just trawled though a few of these pages. Seems DTS is a safe option. I've just started on Enterprise manager, trying to create a package in the meantime to transfer data every day from some test SQL table from one DB to another DB on our sql-server. Looks like I should go over to the client next week, and setup a DTS package on their SQL-Server, try and connect to their Oracle tables and go from there.

    I'll check ot the LINK server, I'll need to connect to their legacy Server

    Cheers
