All the above pocess should work automatically from the local database server because I need to update the remote one so that the website visitor can get the updated results in the morning.I need a detailed description/ procedure to accomplish the work.

I have a SQL Server database which contains stock market quotes and other related data. This database needs to be updated at regular interval, say 1 minute. My question is: How do I get stock quotes every 1 minute and update it to database?
View 2 RepliesI have a project to build a portable customer information app. Because the client works in remote locations, there is not always Internet service available, so a live online option is not feasible. I plan to construct the project with Visual Web Developer 2010 Express, with .aspx pages for data entry and use an .mdb to store data.
The client has a small server on their site. I can install SQL and copy all tables from the app into a new database. However, I'm not sure how to set up syncing between the portable copies and the onsite database. My questions are:
How do I link the portable with the onsite SQL database?
Through a script, or do I need to use Linked Servers in SQL?Would an Insert statement work? But how do I compare the two, as there may be changes on either side...?
How do I initiate the transfer?
Through a Submit button which runs the script on the user's page? Or, do I need Visual Basic or a SQL script?
I have a button click event code block in which data should be updated to my database. After stepping through the code, the ExecuteNonQuery() executes, but no data in my database is changed. I don't think there is a problem with my code although I will include it just-in-case.

I'm confident that my command text and my parameter adding is correct.

View 8 RepliesI have taken over development of a asp.net 3.5, c#, MSSQL website, which I did not create.
There is a form on the website which adds all kinds of information into my SQL database. I have added two fields to the database, two corresponding extra form questions and added to the c# code behind so that these new fields are treated in exactly the same way as the existing ones.
I am therefore completely stumped as to why those two fields aren't populated in the database when I submit the form.
No page errors or anything, it's just the fields remain empty when the other pre-existing ones are populated just fine.
Is there something obvious I'm missing - for example is there a setting in the database I'm not enabling to allow the two new fields to be written to by my c# file?
I was not a programmer before this, I'm just picking it all up as I go along.
I am working on my first web site using ASP.net. In the past I was working with ADO to build Windows Forms applications.To the point...I want to know how to link my SQL db with the db that is inside in the ASP Web Site project. If I change the database using SQL Management Studio the data will be updated until I remove the .mdf of the project and add again the .mdf from my folder of SQL. I need to be able to update the database outside (Via the WebSite) and inside using SQL Server.

View 10 RepliesI have created normalised data tables to hold look up information (such as venues, players, teams etc) and want to dynamically update the 'matches' data table (my transactions) using webpages instead of running SQL queries.
What I want to do is select a name from a drop down list and then post the relevant ID associated with that name to my 'matches' table. At the moment I can only link to the value in the drop down list, i.e. the name which is incompatible with the validation which expects a primary key integer.
I'm sure this problem is a fairly common one but I haven't found the right answer on any of the tutorials or blogs, all of them assume that the data is de-normalised or describe things in more technical ways than I can yet understand. If anyone can point me to a 'how to article' or tell me what I am doing wrong, I would be grateful.

This issues has been driving me nuts. I am trying to follow the tutorial on [URL] I am trying to connect to a database in Microsoft SQL Server 2008. The way I do this is by right clicking on the "Data Connections" > Add Connection. Afterwards the Add Connection window comes up, I make sure my data source is "Microsoft SQL Server (SqlClient). And, I choose a server name; the only server I can choose is DomainSQLEXPRESS. The issue is when I go down to the "Select or enter a database name" drop down box, I do not see my database listed. I have also made sure in the SQL Server Management Studio that I have given my user all the privileges for the database. I know my explanation is kind of vague, but would anyone know the reason why I would not see my database?
