No these are all things that you need to account for while devoloping. Make use of time stamp columns often. Ultimatly the disconnected model is less stress on the SQL server. This topic has come up several times on the message board, search it for "disconnected database" and you will find long conversations about how to deal with some of the issues you brought up.
I'd love to help, but unfortunatley I have prior commitments monitoring the length of my grass. :Andrew Bleakley:

In that case either you have given everyone the ability to log in via windows authenticaion, or the user name and passwords are out in the open.
A user cannot log into the database unless they supply the credentials to SQL Server that they have permission to log in.
If the user names and passwords are not in the open, perhaps you should review the logins to see who actually has access.

You cannot.

If you install MSDE then you can attach your SQL Server 2000 database files (so long as they fit the restrictions of MSDE) and then connect to MSDE. NOTE: MSDE is the desktop edition of the SQL Server 2000 database engine - so you are still installing the engine in order to connect to the database.

Quote:If you are still not convinced then perhaps there is another reason you should look at migrating. Microsoft is working hard to help customers achieve the highest levels of security. As part of this push we have made the decision to not support MSDE on Windows Vista as we believe the combination of SQL Server 2005 Express and Vista is a better choice.

Hi guys,
I'm writing a program for the high school where I work, I'm using VB 6 for the interface and MS SQL Server 2000 for the Database server. The thing is our school which belongs to a foundation (which also holds a consultant company) has two different network, the first is 192.168.212.* and the second is 192.168.3.*. I do the programming on the 192.168.212.* network and can access the server just fine if it were also installed with the 192.168.212.* IP number, can you guys please help me as to how can I make my program able to access the server if it were installed on the 192.168.3.* network. Any help would be much appreciated.

Hello,
I am not much of a networking guy and I've had the luxury of not dealing with subnets, but I'll give it a try :->
I have a few questions. Who is on 192.168.212.* the school or the consulting company? Have you tried using the computer's network name instead of the IP?

If both networks is on the same cabling system or the same routers. You can do a few things
1) Give each server two IP addresses one each subnet
2) Configure a router to route between the two subnets
3) You can also configure a Windows server to route between the two subnets ( this is easy and cheap)
If the are different cabling / routers then you need to a physical router or and another network card to a server and add the routing.
Look where you want to go not where you don't want to crash.

Hi Frank,
my system admin said that the two subnets are running windows server connected by a linux server, configured as a router. the linux server also route to another linux server (the gateway so they call it) to connect to the internet, each subnet's windows server are also using 2 network cards with different subnet, I have tried to access the server in the school domain (the 192.168.3.*) from my office (192.168.212.*) both by calling the server by name or ip number, but I still can't access the data. I feel awful to bother you by asking this again but I really need it to work. he also said that the port for sql server is not blocked by the firewall. can you please help me.

Not that it entirely matters, but can you ping the SQL Server? Odds are you wont be able to becuase of the subnetting thats in place.
What you may need to ask the network admin to do is create a vlan between your subnet and the subnet that the widows box is on.

I have another question, are you located on the same campus? Or are you accessing the school through the internet?

If your network admins find out that your attempting to statically link to a specific IP address their going to laugh at you during the next network review and change the network schema. You are far better off relying on DNS to do the proper translation; that is what it was invented for after all.

Hi Douglas,
I believe they are laughing at me right now, but I don't mind, as long as I can finish my work it's fine, by the way, I have also used the computer name to access it besides the ip number but it didn't work either, is there any other solution to this. Thanks and sorry to bother you.

Yes ping the server or use telnet on the SQL port number to see if you can atleast access the server in question.
I use telnet sometimes to access SMTP server to see if its open
telnet server port

We use SQL Server as a backend for our .NET application. Mainly the data manipulations(insert, update & delete) are implemented in the stored procs themselves. What if the customer wants to change the rdbms to Oracle. As far as the front end or data layer is concerned simple changes wud be enough like changing the provider, connection type etc. i beleive. As all the data manipulations are done through stored procs, how will we convert the Stored procs written in SQL server to Oracle simply. There wud be many features that r SQL Server specific. Do we need to modify each and every stored proc after convertiing to Oracle. or the database convertion tools will do the job for us.
Think that we r using Stored procs extensilvely for the data manipulation.

You will have to rewrite just about every stored proc as there is specific TSQL features that are not available or implimented different in Orcale.
As someone once said "This could take some time"

Hi
as you know with OleDB we can open many kind of DataBases.
i want to know is there any difference between SQL statements we send to darabases or all of them support support a single tyoe of SQL statements.
I wanted to Get Information of tables of Databases(something like "Server Explorer" of VS.NET which opens every Type of Databases and shows their "Tables" and "Queries" and "procedures" and "Functions". abd also Field Types)
can i do it with SQL statement? and if yes are they different for different databases?

Yes and no. Most Structure Query Language statements are the same, but each database (MS SQL, MySQL, Oracle, Firebird, etc) have their own minor differences.

Most support a industial standard called Sql-92 which will in theory work with any compliant SQL-92 database. But sadly in pratice it doesn't work like that and small quirks make problems porting sql code.

I stand corrected

You were correct in the fist place. You said "most" use SQL-92. I just thought I'd add that "some" now use SQL-99. If I remember correctly, SQL-92 is a subset of SQL-99, so it could be said that everything that is based on SQL-99 is, by default, also based on SQL-92.

I think SQL-92 relates to 1992 and SQL-99 relates to 1999. But I'm guessing
