sql server connect : Need to interface MS SQL in C++...
Greetings !
We need to find if MS SQL has an API for connecting C++ components to it. We don't know if "extended stored procedure (xp)" is the way to go. Why do we need that ? We must implement a synchronization software layer to make sure an ODBMS has the same values as those contained in an MS SQL RDBMS. Our client applications must use the data in such a way that doesn't fit with the relational paradigm... But the data must be stored in relational fashion for it needs to be easily extracted or used by our customers. We would like something that follows the "Observer Pattern" to notify an ODBMS that a table was modified through the standard "Create", "Update" or "Delete" events. In fact, it would do more than just notifying. It would actually push the modified values to the ODBMS space to update it. It would also need to do the opposite. (i.e. Push modified values from the ODBMS domain to the RDBMS one.) Thanks for any help ! _________________________ Acoquinar

Hash: SHA1 Before worrying about C++ routines I'd use the SQL Server's Linked Server ability; then apply triggers to the SQL'r tables you want in "Observer Pattern" that will "push" the data on the ODBMS db. Conversely, if the ODBMS db has triggers, create them on the tables that you want to "push" data into the SQL Server db. See any db design book for more info on Triggers; or, look in SQL Server's Books on Line (BOL) for info on triggers and Linked Servers. -- MGFoster:::mgf00 <at> earthlink <decimal-point> net Oakland, CA (USA) -----BEGIN PGP SIGNATURE----- Version: PGP for Personal Privacy 5.0 Charset: noconv iQA/AwUBQbYuFIechKqOuFEgEQK9UACfVEtTsRQuy1fNdoBOnXVR85Z2Kw4AoN8j s2fiH6EHoE1LqVGrbZZh55lp =WLkd -----END PGP SIGNATURE----- [quoted text, click to view] acoquinar wrote:

Surprising the technology you want is called Notification Services http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sqlntsv/htm /nsp_programmingguide_8neb.asp
Our goal is really just to create a "Replication" mechanism like the one
associated with SQL Server. The difference is that we don't wish to syncronize between more than one SQL Server instances...We wish to synchronize between a central MS SQL Server and remove ODBMS servers. It implies a intence synchronization for any DML operations (i.e. "Insert", "Delete" or "Update") that would occur on the SQL Server instance. Which entry point or API could we use to do that ? P.S. "Notification Service" doesn't seam to be an API for sending notifications based of events that occur in the tables. (Correct me if i am wrong here !) Thanks !

Correction,... (REMOTE instead of remove)
The difference is that we don't wish to syncronize between more than one SQL Server instances...We wish to synchronize between a central MS SQL Server and A REMOTE ODBMS servers.

That is why we say that it's probably not what we're looking for.
We're not looking for a User Oriented feature but an API that allows us to trigger synchronization routines based on any transactions made in a DB. We probably something more low-level no ?

No, the notification server is designed to allow messages to be dispatched to different subscribers in different formats over a wide variety of protocols. The main examples given in the book are to human receipients, however the technology works just as effeciently and effectively for other applications and systems. You'll see that the API has support for both subscribing to notifications as well as being able to send and receive notifications.
