Conecting Over The Internet For Getting Data From Clients.
Jul 23, 2005
I want to connect over the internet to get data from clients.What would
be the easiest method and the most stable methos to do it
1.Use a Point to Point prtotcol from the client pc and then upload the
data to our sql server
2.Export the data from the clint pc in XML format and then Enter it in
our computer.
3.Have all clienst ftp the data in a dirctory and then upload the xml
files from the directory?
Thanking you in anticipation.Would love it if we could discuss and
distribute our thoughts on this.

HI
Q1: Does Sql Server 2005 Express support Web/Internet to other SQL Server 2005 Express Clients or does it have to Synch across the internet to a fully installed setup SQL Server 2005 with IIS?
Q2: Does SQL Server 2005 Express support Direct Replication between other SQL Server 2005 Express clients?

I am someting of a newbie to SQL Server, but I am an experienced C++/C# programmer.
I have a SQL Server 2005 DB to which are connected 50 or so clients.
The clients are running my software, written in C# and connected to the server by an OleDBConnection.
These connections are long-lived; in some cases they remain for days or more.
Now and again, one of the clients causes a change to the DB (not structural, just normal adds, update and deletes).
But most of the time the clients are just viewing data in the DB.
What I need to happen is that when any item of information changes, the display of that information on any of the clients which are viewing it must be updated quickly.
It doesn't have to be instant, but a delay or more than, say, 5 seconds is unacceptable.
It is like a share-dealing or foreign exchange system (although that is not what it is) where the traders' screens have to have up-to-date information at all times.
Note that the information received by the clients does not have to describe the change in detail, just a hint to the client as to what change has happened so that the client can refresh its views.
I can think of a way of doing this but it is really nasty.
The hints would be recorded in a time-stamped table. Each client would poll every couple of seconds by calling a SP, which would return the hints which have been added since the last time that client polled.
But polling is horrible and I am sure that there must be a better way.
A route that looks promising is InfoMessages. But, reading around the subject, it looks like these cannot be unsolicited and spontaneous; they only arrive on a Connection as a result of some action on that Connection.
I may have missed something, or maybe InfoMessages are not the way to go.
Can anyone offer me any advice, please
TIA,
Paul

Hello,I'm looking into offering a custom data driven web app that I wrote for an organization that I'm apart of to other similar organizations. I would be hosting the data and web application code on my dedicated server. This application is using the membership api supplied in .NET 2.0 and also has my own custom data tables within it.My question is what would be the best way to add clients to this? Should I simply create a new database for each new client like so: ACME_Database, ABC_Database, AAA_Database etc. Or should I add some sort of client "Tag" (tag meaning column within each datatable) to these databases and then update my SQL queries to process them accordingly. I imagine I could do both but I guess I need some advice from people that already had experiance with providing this kind of service. Thanks!Jason

I have SQL Server running on my internal LAN. I want to have a second SQL Server running on a hosted (shared) website. I then would like these servers to talk to each other. At some scheduled time I need to publish data to the web, and I then need to subscribe to data input on the web by various clients. My internal LAN can see the Internet via our cable modem.
What is the best way to do this? What software will I need to run. I'm looking for the big picture.

Hi
The situation is this. I have a desktop app which exports data to sql 2005 across internet. What is the most robust way of doing this and what security should be in place?
I have heard that sending data across to sql is not the best & safest way, but unfortunately cannot really do anything about this. is there any way of getting over the problem if connection goes down while uploading, and is Bulk Insert the best method?
Would appreciate any comments on "need to copy data to sql 2005 over internet in best way" if possible.
Many thanks

We have an information retrieval application in which there is a single connection to a database followed by multiple table open, read, and close commands. Response time is consistantly less than 1 second on a LAN.
When Internet connected (not VPN), the first table read is typically fast, but the response time becomes slower and slower after multiple table open, read, and close commands. There seems to be a considerable amount of handshaking based on monitoring of the router's status lights.

I'm trying to get the last ten unique clients viewed by each user. I have tried using the TOP (N) but it does not show the last ten just any ten.
When a user views a client record, a record is saved to the tblUserRecentViewedClients table and includes logID (key), client_id (int), username (nvarchar), lastviewed (datetime).
Here is what I have so far. Can anyone offer any suggestions?SELECT TOP (10) tblUserRecentViewedClients.UserName, tblUserRecentViewedClients.Client_ID, tblClient.FirstName, tblClient.LastName,
tblClient.CompanyName
FROM tblUserRecentViewedClients INNER JOIN
tblClient ON tblUserRecentViewedClients.client_ID = tblClient.client_ID
WHERE tblUserRecentViewedClients.UserName=@UserName
GROUP BY tblUserRecentViewedClients.UserName, tblUserRecentViewedClients.Client_ID, tblClient.FirstName, tblClient.LastName,

Are there any issues with retaining both the SQL 6.5 and SQL 7.0 clients as
installed components on our desktops? We have a number of SQL 6.5 and 7.0
Servers which have some fairly specific client side requirements and I am
trying to ascertain what the potential impact is to rolling out SQL 7.0
components to a separate directory to allow all applications to coexist. My
specific concerns are with the shared DLL's in system32 and with updated
7.0 executables that share the same name (i.e. BCP, etc) and resultant path
issues.
Any feedback or articles that cover this subject would be appreciated.
Thanks,

I have situation like this:
Company with one head office and one remote office. In the two offices I have two domains with two PDCs. The two networks are connected with eachother through leased line and the routers are configured properly. The SQL Server is on the PDC in head office and "local" clients connect fine. I cannot connect from the remote office. I think that I have folowing solutions:
1. make trust relationships between two domains - it will be hard a little bit because second PDC is samba on linux
2. make all clients in remote office to be members of the head office domain - potential problems if the leased line drops
3. make all clients to log in with same account as SQL Server logs locally - stupid
4. something else - what?
Thanks in advance!

We’re having trouble getting error messages to show up on clients. Our ADO research indicates that the Errors collections is populated, “automatically” – what you do with it is up to the application. Our collection is not being populated. MS says the SQLOLEDB provider has a problem (the collection is not filled) if SET NOCOUNT is OFF. We have SET NOCOUNT ON and still have the problem. We have narrowed the problem down (the example below is an abbreviated version) to “the Errors Collection is not populated if the Raiserror follows a SELECT statement that returns a recordset”.
In the code below the simple select run after the first RAISERROR appears to “block” the Error Collection. Is this by design? Are you never supposed to be able to return records and messages from the same program? We can code around it if we have to, but the documentation seems to indicate our approach is viable.
Any ideas would be most appreciated.

Hi all,I've got a question concerning synchronization of multiple database clients.Consider a database, accessed by two clients. Is it guarantted, that ifclient 1 succefully commits a transaction, client 2 _instantly_ sees thechanges made by client 1?thx and regards,StephanP.S..: For MS Jet databases I know there _is_ a delay between writing datato the database and being able to read this updated value from anotherconnection,so the question refers to "real" DBMs (esp. SQL Server) only ;)

We have a situation where multiple-random client connections to SQL server get disconnected.
The workstations are not consistent, the time is not consistent, and the functions being run are not consistent. One thing that we can reproduce is that sometime, but not always, if a workstation runs a function that calls a specific stored procedure (SQL native client, ADO, SQL Server 2005 SP2), during the course of the parameter validation (after the .execute) SQL sends an ACK, RST followed by two RST TCP packet back to the client and disconnects the connection.
At the same time, several other connections across multiple computers are also dropped by SQL. However, some computers may have multiple connections to SQL and some, but not all of these will be dropped. Other computers will
not have their connections dropped at all.
No SQL server errors are logged. Trace flags 4029 and 3689 have been set.
We have the network packet traces and the SQL profiler output to show this.
This is not reproducable at any other site.
Any ideas on what this could be would be greatly appreciated.

Hi all,
I've been running SQL Server 2005 for over three months, and have got the database up to speed. Using SSMSE for an interface.
I've have been trying to get the Intranet to link to the database (ASP), but after a little research i found we needed to change the Authentication from 'Windows Authentication' to a mix of windows auth and sql login. Needing to restart the server for the changes to take effect.
After the restart things started to go pear shaped.
Before the restart we were able to run queries from different clients at the same time (4 workstations). Now we are unable to access anything on the database if a query is running on a seperate client. As in table properties, running a query. As i've said, we were able to do this perfectly fine before the restart.
We also use other programs to generate records for the database. These programs now have difficulty connecting to the database. We've gone through the wizards and as far as we are aware things should be working. We have created extra username/logins for these programs so not one computer/client/program uses the same connection login. However, they are unable to connect even after the wizard says there is no problem connecting to the server.
Is there any *restore to factory/default settings* button? We've even tried reverting to Windows Authentication to try and solve the problem, but it didn't work, we're pretty dependant on the database for day to day operations.
Anyone with an idea as to what's wrong?
Thanks in advance
Gary.

Hi all,
I have a couple of client programs continuously dumping data into a SQL 7.0 database. I use ODBC connections that remain open as long as the client programs are running.
The memory consumed by SQL grows until all the system memory is consumed at which point the clients freeze (SQL no longer responds). Restarting SQL Server "cures" the problem for a few hours.
I've tried limiting the amount of memory used by SQL, but this only accelerates the eventual client freeze-up. At the moment, I let SQL dynamically consume memory.
These same client programs ran fine under 6.5
Thanks for any help..
