This may be a simple question, but I'm trying to call a a value from table in my back-end SQL Server database and pass it through a querystring in the URL. For example:
I'm building a mobile web site that registers a mobile device to an account on the sign up page. After the database entry is created, I want the to get the generated deviceId from the database and pass it to a querystring in the URL such as: http:[url]....

I'm looking for a front-end that's very simple, to access a to-be-built MySQL Database. I actually need it for only one table. I was thinking that the user could search in a way that would ask for values for each field of that table, and give the option of leaving it blank. Then, it would return all the entries that match up with the query.

I am asked to write a front end program in VB 2005 (that will run in client computers which running on Win XP) to access an existing MySQL database running in Linux. It is not my preferred choice, but the user have the database and server working just as he wants it, and do not wish to change, at the same time I do not wish to change programming language. Is that even possible? Can we actually write VB 2005 programs that will run in client computers complete with NET framework 2.0 to access a Linux operating database?

I have Visual Studio 2008 installed and I will use Visual Basic from that. I also have Oracle 10g express edition installed on my system.

We are thinking about changing our current database system, MS Access 2007 front end and MS SQL Server 2005 backend to using a higher level language such as Visual Basic .Net. I wonder if this is the BEST solution for data management? Currently, among others, we have two big database programs that handle more than two hundred users and it's crashed often. That's the reason we think about changing to something that can handle these database programs effectively preferably using MS technology such as .Net.

Disclaimer: I didn't place this in the Database forum because since I'm so new to VB I might not even know of some kind of ingrained function for the saving of data. I have NEVER used standalone VB (I have 2010 Express now) -- I've always used VB 6 in MS Excel for the storage of data, so I really DON'T KNOW what is possible with VB6. (I also don't want to learn ALL of VB just to see what direction I need to go in, I'd rather get a direction -- even if vague -- and learn from there)
Goal: I want to write a standalone application for the creation of, storing of, manipulation of, etc records in Visual Basic 2010.Specifically what I want to do: IN VB, type in a bunch of client information in a variety of fancy windows, and when I'm done, have that client record saved in some kind of database.
Problem: I've tried Googling a ton of things about reading and writing from files (txt seems easiest for me at this instant) and I also see APPENDING to the end of a file. I don't see how a record in the file can be UPDATED. I see saving, I see loading, but I don't see (for example) the identification that I'm trying to save another record for Client 1234 so that it saves over the old client's record with the updated information.
1) Is this possible?
2) What database format would be preferable? (Right now I'm aware of txt, xls, csv, or access as possible options) I'm sure there are strengths and weaknesses to each but if there is general watered down version that would be awesome (I'm not trying to suck away anyone's life force)
3) Sample code, if possible, for whatever record solution you recommend using?(And I know that Access is generally pretty darn awesome, but the final project that I'm hoping to build to is likely to surpass the 'reasonable size limit' of Access that I've been told about)

I have an application that will be called by a database(this application is called from an access shell that uses SQL Server Tables), my question is do I need to provide a connection string to write to the database or since it is already open I can just pass the insert statement. If I am to provide a connection string do I use OLEDB JET 4.0 or ?

I am trying to write VB.NET query without writing SQL stored procs. I have already gotten many dataset text queries to work. But I am having trouble with getting this scalar query to work. All I want to do is to get the result of this T-SQL query. How can I code this successfully? select (DateDiff(w, '1/1/' + '2011', getdate())) / 7 AS SELECTED_WEEK (What this code does is it returns the current week of the year). And will this query above return the value as an integer datatype or string?
I tried your answers but it gave me this exception error:
System.InvalidOperationException: ExecuteReader requires an open and available Connection. The connection's current state is Closed.

Is it possible to create database queries on the fly with VB?
For i = 0 To (UBound(WeekNo) - 1)
For NLoop = 1 To 50
WeekRow(NLoop) = WeekSinceLast(i, NLoop)
Next
Next
I want to write each WeekRow to the database for each week (= i). WeekRow contains 50 elements, each of which needs to be placed in a separate field.
So, can I generate a SQL query that is constructed on the fly? If so, how do I go about it?
