Sql Server - Read A Full Table From A SQL Database?
Jul 27, 2010
I hate to ask this question on this forum, but I'm having a lot of trouble finding it on these online tutorials. Basically, I'm learning about SQL, VB.NET, and how to glue the two together, and I've learned about using SqlCommand.executeScalar() to get the first entry in a table. But that's all it's really good for, right? Or is there something more to the story here?
Basically, I'm wanting to ask about how to pull in a FULL table from a SQL database while using VB.NET, as well as how to pry substrings and stuff from it. Again I'm having to ask this on this forum because all these online tutorials seem to ignore the subject completely.

I have an SQL database set up on my web server. Is it possible to read from a table in that database and display a value in a textbox, for example? I want to store valid values in a server database and then check the entered values in the application against the server values.

I'm developing a VB.NET application to obtain data from any data source (using an odbc connection string), and because this i can't use specific .net connectors like MySql.Net connector and i can't previously know if the file/DMBS supports LIMIT parameter. This app will read data from a table in the data source and use the information to make some files. At this point there was no problem with some tables because they are less than 3,000,000 records length, but there is a table that has 5,000,000+ rows length, and when i send the query the connection is lost. I'm working with OdbcDataReader, because i read on MSDN site that this is the best way to read a table one row at time and i just use each record once.[code]...

I'm trying to create a VBasic executable to read a SQL server database and produce a mailing list.I have the SQL routine working fine and had set it up as a stored procedure, but I've just discovered the manager I've written this for is an Access-type and does not have SQL Server installed on her machine. So, I figured I'd make a front end in VBasic.
Dim con As New SqlClient.SqlConnection
con.ConnectionString = "Data Source=mySQLServer;User ID=Username;Password=myPass;"
con.Open()

I know how to select items from an array with LINQ, but what I can't figure out how to do is access a database using an IQueryable. I connected the database to my project, added two classes from the database to the "LINQ to SQL" .dbml file and saved it. In my programming assignment, I am not supposed to create a data source (table thing) to display the data, but update my own interface manually. In order to do it, I was told to instantiate this:
Private dogs As System.Linq.IQueryable(Of Dog)
(Dog is a class that I added to my .dbml file from the database file)Also, I am told it involves using a method
.AsEnumerable.ElementAt(index As Integer)

Trying to use asp.net for the first time. I want to read a single value from a sql server database.
I have configured the SqldataSource as:
CODE:
I have the above asp:SqlDataSource code on the website page. The connection string is in the web.config file. When I run the page it is all works but the required data is not shown. Am I right to think that where I dragged the sqldatasource entity is where the data result should be shown?

I am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields:
QuestionNumber (unique integer key)
QuestionText
QuestionType
In my SQL Server database I created a Table called "QUESTION" with the same fields.
QuestionNumber is defined as integer unique key, auto increment
Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1).
How do i have to change my database setup, that the original QuestionNumbers are copied into the database?

The above is more or less the complete question. I have created a table in the VB 2010 Database Explorer but I cannot for the life of me work out how I can get this copied or created into the underlying server. It is not appearing in the underyling serverand when I run the code of course I ge "invalid object <tablename>" I have data as well in the table that appears in Database Explorer. I think I have missed something fundamental in my overall conception of using VB 2010 Express with SQL Server Express in that I don't know if I have a local copy (that isn't then mirrored on the server), or what (the ____ have I got)? An article that explains the overall relation of Database Explorer to the underyling Server would be great as well

I can use appactivate to bring forward a screen on another program if I know it's title (or at least part of it's title). Is there a way I can read the full title of such a screen if I bring it into focus? e.g I have a screen from another program which says "Patient Mrs Smith". I can bring it to the front by doing an appactivate from my VB prog and calling appactivate("Patient"). Is there a way that I can find out the full title from my VB program?

My program has to store files externally to work with. Before now the path was fixed at C:/DSGameMaker, I did the following:
System.IO.File.ReadAllText("C:/DSGameMaker/data.dat")
However I want to let users install the program wherever they want, so I changed that line and others to:
System.IO.File.ReadAllText("data.dat")
Which works great, until you do this:
System.IO.File.ReadAllText("D:/X/Y.Z")
As soon as I put a fixed path into the ReadAllText function it changes the relative path to D:/X. Which means the following function looks inside D:/X instead of the apps directory:
System.IO.File.ReadAllText("data.dat")
And complains that "D:/X/data.dat" is not found.
How can I use relative paths but also read from full file names, for example from an OpenFileDialog, without VB changing my relative path, and breaking it all from then onwards?

I want to update to v1.5.3, but the original integration code no longer works and I can't see how to fix it.Secondly, I would like help adding drag and drop features so that I update the database on drag/drop from asp.net, but I'm not sure where to start for that.

I have a simple Windows Service that reads from an Excel spreadsheet and imports the records into a SQL Server 2000 database table. Before it loads it checks if the file has been successfully imported before (using filename) and whether any of the records in the file have been imported before (using primary key). If these checks are ok I load the records into a datatable and then update the datatable to the database.
However, I need to do this in a transaction as I want to ignore the whole file if there is an error. The file goes to a discarded folder and the user gets an email with why the import failed. (This is likely to be because the store the record is for is not yet added to the database and the referential intergrity of the db fails). If there is no transaction the records before the failure record are imported. When the file is imported again (the store has been added to store table) the file is then rejected because duplicate records are already in the db.
Heres my code:
