Reading/Writing Data From A SQL Database

Feb 14, 2008

Hi,
I have a data structure called 'Quote' which contains a number of different variables and controls ranging from text boxes, check boxes and radio buttons, i need to be able to read and write this from a database.

First I think a description of my overall project is needed:

Project Description
I have been given a brief that basically says: i have to create a programmed solution in VB to solve a problem. This problem can be anything we like, and I personally have chosen to create a program that manages quotes for building Log Cabins (this is very contrived and far from anything someone would do in the real world).

My solution will allow a generic user to create a quote (using a form with controls such as text boxes, check boxes, radio buttons) , and then save this to file. These users may then wish to load/edit this quote at a later date, from another form.

Whilst completing this project, i'll only have up to about 5 records (quotes) within the system, so i dont need the ability to store hundreds of records. And each record will be relatively short, with only about 10-15 data items within the data structure.

Also the Admin (or business owner in this case) need to be able to view all saved quotes in a presentable format, and edit them if needs be, from within this same program.

This solution does not need to be absolutely perfect and 100% efficiently coded, or have all the bells and whistles a real-world program would have. This is for an A level computing project by the way.

So basically, i need to be able to read from the database (to populate a Data Grid (i imagine this is best way?)) and so Admin can access any quote and edit it (editing is not vital, but viewing/printing is. Maybe i should stop at just viewing any quote?). Also i need generic users to be able to fill in the Edit Quote form and then save this data into the database.

And is a data structure really required for me to use a database?

I've never used databases in VB before (but have used them elsewhere, mainly Access) and so am completely new to this. Any help will be much appreciated.
Thanks

Reading And Writing To Same Table

Feb 16, 2008

I need to select all the records in a table, loop through them one by one, calculating some new field data, and then write the new data back to the same table. Here is the basic structure of what I've come up with:<CODE>SqlCmd = SqlConn.CreateCommandSqlStatement = "SELECT ProductID, Name FROM tblProducts"SqlCmd.CommandText = SqlStatementSqlRdr = SqlCmd.ExecuteReaderIf SqlRdr.HasRows Then While SqlRdr.Read If SqlRdr.FieldCount > 0 Then ... SqlWriteCmd = SqlConn.CreateCommand SqlStatement = "UPDATE tblProducts SET Name = '" & NewName & "' WHERE ProductID = " & CStr(ProductID) SqlWriteCmd.CommandText = SqlStatement SqlWriteCmd.ExecuteNonQuery() SqlWriteCmd = Nothing End If End WhileEnd IfSqlRdr.Close()SqlCmd = Nothing </CODE>I get an error that tells me to close out the Reader before trying to execute the write query. But I can't close it out for the loop to work properly. So I assume that there must be another way to do this simple task, but I'm so new to all of this that I need some help! Thanks!

Reading And Writing To Databases

Jun 13, 2007

I am new to database programming. What I want to do is have a database on a clients PC to use as data storage. This program will connect to a program running on our server (via TCP) which will store this information in another database. The clients database will only be accessed by my program - so I think that I don't need to register it with SQLEXPRESS. The servers database will probably need to be so another program can access it.

The problem I was having was writing and reading to a database that I created inside Visual Studio 2005. As I see it, there could be three issues - reading, writing, or setup of the database. To find out this issue I downloaded the Northwind database. The code below returns column 0 row 0 of the Customers table.

Code Snippet

NORTHWNDDataSet northwindDataSet = new NORTHWNDDataSet();

NORTHWNDDataSetTableAdapters.CustomersTableAdapter customersTableAdapter = new NORTHWNDDataSetTableAdapters.CustomersTableAdapter();

customersTableAdapter.Fill(northwindDataSet.Customers);

string data = (string)northwindDataSet.Customers.Rows[0].ItemArray[0];
Console.WriteLine("COL 0 - ROW 0: " + data);

This code returns "ALFKI". Which is what is in col 0 row 0 (This can be checked by right clicking on the Customers table in NorthWNDdataset.xsd and selecting preview data).

Next is writing. This is where I have the issues. The method below is one way that I tryed.

Code Snippet

DataRow row = northwindDataSet.Customers.NewRow();
row[0] = "1";
row[1] = "2";
row[2] = "3";
row[3] = "4";
row[4] = "5";
row[5] = "6";
row[6] = "7";
row[7] = "8";
row[8] = "9";
row[9] = "10";
row[10] = "11";
northwindDataSet.Customers.Rows.Add(row);

try
{ customersTableAdapter.Update(northwindDataSet.Customers);//table);
northwindDataSet.AcceptChanges();
MessageBox.Show("Update worked");
}
catch
{
MessageBox.Show("Update do not work!");
}

The messagebox shows "Update worked" - yet the data did not get added.

Thanks in advance.

Using:
Visual Studio 2005
C#
SQL Server Management Studio Express

Reading And Writing Same Variable To A Script

Apr 27, 2006

It looks like its not possible to both read and write the same variable from a script using the conventional Me.Variables.<variable> syntax.

I can only assign a variable as Readonly or ReadWrite and not both. If I assign it ReadOnly I can only access it in the PreExecute subroutine. If I assign it ReadWrite I can only access it in the PostExecute subroutine (in fact doesn't this just make it WriteOnly in fact?). So I can only either read in or read out a variable using this syntax, noth both. Is this right?

So the read and write a variable to a script, the VariableDispenser approach is the only option to use. Is this right? and is it documented somewhere that this is how to use variables in scripts. Thanks.

Reading Variabels From DTSX==&&>Writing

Jul 20, 2007

Hi,

I want to make an application that fills in the variables into a dtsx package (ssis).

I'm able to read the variables created in the package

Application app = new Application();

Package p = app.LoadPackage(pkg, null);

Connections myConns = p.Connections;

foreach( Variable v in p.Variables){

Console.WriteLine(v.Name);

Console.WriteLine(v.Value);

Console.WriteLine(v.Namespace);

Console.WriteLine("/////////////////////");

Console.WriteLine("/////////////////////");

}

i'm also able to add on

Variable myVar = p.Variables.Add("amyCustomVar", false, "User", "3")

When the applications is closed the package does not contain the variable. So this is all done in memory.

Is their a way to actually write the variable into the physical package.

Reading And Writing To Flat File

Apr 27, 2006

I'm doing a test package which reads a flat file, makes an adjustment using the derived column task and writes to the same flat file. But, the read locks the flat file, so the write can't access it. Any ideas for a resolution?

Thanks,

Reading/writing Files To Network Drive

Mar 20, 2007

We have a package that is using a ForEach loop container to access files on a network drive. For some reason I am getting a message that the ForEach enumerator is empty and did not find any files that matched the pattern. For the pattern I left the default *.* for testing purposes. I have specified the file folder as \remoteserverfilesharesubfolder and also as \remoteserverc$filesharesubfolder and have gotten the same message. However when I map a network drive and set the file folder to the network drive it finds the files. Is this a permissions issue?

After I finish processing the file I want to move it to a new directory. Once this is deployed in production, the package will not be running under a domain account and probably won't have access to the network folder. Is there any way to specifiy in the connection manager itself that it should use a specific account to access the folder?

TIA,

Sabrina

Connecting To And Reading Data From A SQL Database

Jul 25, 2006

Hi Everyone,
I am looking for some help, as i am pulling my hair out looking for information.
I have been using asp for many years and am now starting to learn .net. so far so good....
I am now wanted to connect to a database, execute a simple select statement and then read/write the information out. I can't help but think in old asp code and i am having a hard time finding what i need to perfom this simple task.
I have used the grid controls etc, and these are very good - however, i need to connect to a database in the code-behind file and perfom various functions in the background.
If any of you could be so kind as to perhaps show me some demo code i would be grateful.
I would like to do:
A) Connect to a database (sql server 2000)B) Execute a simple SQL select statementC) Read the returned informationD) put this information into variables used elsewhereE) how do you check if no records are returned? such as the .EOF in asp?
Many thanks
Darren

Problems Reading Data From A Database

Mar 24, 2008

I have a database that contains news items. There's a column that contains the actual article. In that field, there are paragraphs with page breaks. The page breaks in the database are represented as squares (unrecognizable characters I guess). When I try to read in the data, it doesn't recognize the page breaks, and it comes out all in one large paragraph. Is there any way to get around this?

Reading Data From A String Into A SQL Database

Jan 18, 2007

Hi, i'm writing a SOCKET Port Listener for a Database, it must be multi-threaded and listen on a port for a record that when it comes in, it must write the record to the SQL database (MS SQL Server). I've got the listener to read the data over the port already and write the record into a string which i have already sliced up. Now i need to create a connection to the database and insert the variables into the database.

If Someone will please be able to give me a rough idea of how i could accomplish this with some sample code, then i will be greatful, i'm new to C#, but here is my code that i have so far.

//This is the Connection that i have made and where i am currently stuck, i dunno how to go further. Any help will be welcome.

public class ConnectionToMSDatabase
{
public void InsertDataIntoDatabase(string TableName, string connectionString, string dataFields)
{
string InsertSQLStatement;
InsertSQLStatement = "INSERT INTO " + TableName + " VALUES (" + dataFields + ")";

OleDbConnection ConnectionToDatabase = new OleDbConnection(connectionString);
ConnectionToDatabase.Open();
OleDbCommand command = new OleDbCommand();
command.Connection = ConnectionToDatabase;
command.CommandText = InsertSQLStatement;
command.ExecuteNonQuery();
command.Connection.Close();
}
}

//Here is my connection string, all the retrieved data is stored in a string array call fullRecord

ConnectionStringToDatabase = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;User ID=" +

Writing Binary Data To Database Only To Refrence A File Location?

Sep 29, 2006

Hey everyone I've got this question that has me stuck for the last few days but its an important part of my website.....What I am trying to do is basicly have a user be able to upload a file, have that uploaded file plus some other info automaticly display on other parts of my site, and have a different user eventually be able to download that file....I have thought about allowing the file upload as a BLOB but still cannot find a proper way to execute this using VB, plus I have heard that this way of doing it is not reccommeneded cause databases were not designed to store large files like this, lots of articles recommened having the file upload to a Folder on your server then get the binary data for the file that can be placed in a database to refrence that particular file.....Well this also proves to be a lot harder then said here is what I got so far (written in C#) protected void UploadBtn_Click(object sender, EventArgs e)
{
if (FileUpLoad1.HasFile)
{

FileUpLoad1.SaveAs(@"C:Documents and SettingsAdamMy DocumentsVisual Studio 2005ProjectsWebsiteFiles" + FileUpLoad1.FileName);
Label1.Text = "File Uploaded: " + FileUpLoad1.FileName;
}
else
{
Label1.Text = "No File Uploaded.";
}
}
and here is the asp part of the code that goes with it<asp:FileUpLoad id="FileUpLoad1" runat="server" />

<asp:Button id="UploadBtn" Text="Upload File" OnClick="UploadBtn_Click" runat="server" Width="105px" />

<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
Now from what I know is I need to get the binary of the file which I have read you can do with the Page.Request.Files statement but again not sure how I would impliment this. Does anyone have any suggestions on which way I should take when dealing with this should I try and just use the BLOB method or use the binary refrence method? and if so how would I impliment this, heck even some good tutorials on the subject would be great... Thanks.....Adam

Error Writing Data To Same Destination In Single Data Flow

May 12, 2006

I am getting the following error running a data flow that splits the input data into multiple streams and writes the results of each stream to the same destination table:

"This operation conflicts with another pending operation on this transaction. The operation failed."

The flow starts with a single source table with one row per student and multiple scores for that student. It does a few lookups and then splits the stream (using Multicast) in several layers, ultimately generating 25 destinations (one for each score to be recorded), all going to the same table (like a fact table). This all is running under a transaction at the package level, which is distributed to a separate machine.

Apparently, I cannot have all of these streams inserting data into the same table at one time. I don't understand why not. In an OLTP system, many transactions are inserting records into the same table at once. Why can't I do that within the same transaction?

I suppose I can use a UnionAll to join them back together before writing to a single destination, but that seems like an unnecessary waste and clutters the flow. Can anyone offer a different solution or a reason why this fails in the first place?

Thanks in advance.

Writing Data To CD

Jan 18, 2007

Hello,

I am trying to use a recordable CD as the storage medium for a comma delimited flat file destination in an SSIS package. I am running the developer edition of SQL Server 2005 on Windows XP SP2.

I discovered that in the file connection manager for a flat file, the path to the file can point to a directory on the CD-R. When I set the file name for the connection manager and point it to a file on the CD, the path looks something like this;

C:Documents and SettingsjuserLocal SettingsApplication DataMicrosoftCD BurningArchiveMonthlyMCTxnDetail_Archive.txt

When I run the package, the packge executes without a problem, but no 'burning' occurs. When I check the directory specified in 'file name', there is a header in the directory that states, 'Files Ready to Be Written to the CD'. The file I want to write to is listed there.

Is there some executable I can kick off in another task to complete the process of burning the file to the CD?

Thank you for your help!

Writing Files To A Database

Feb 7, 2007

Hi, I'm relatively new to SQL and ASP.NET and I'm after some assistance to what I hope is an easily achievable goal.
I need to upload some files (.pdf, .doc, .jpg - whatever) to a directory on my webserver. Once this has been done, I'd like to write some data to an SQL Database Table that will contain information about these files in a datagrid (or something similar) along with a link to download them.
E.g I upload car.jpg which is located at /images/secure/car.jpg and is a photo of car. When a user logs in, they will be shown a datagrid which pulls information from said SQL database and in this datagrid will be something like:
Filename Description Link
car.jpg A pic of a car Download

If anyone is able to help me out with regards to linking to a file from an SQL dB it would be greatly appreciated, and if you require any further information just let me know :)
Ben.

Tell If Application Is Writing To Database?

Jan 12, 2015

I was all set to build some triggers on some modified date tables when in the last minute I found out that the application (built in C#) was controlling the after update trigger.

Is there a tool you can use in SSMS to see if there is a connection set up like this?

Is There A Delay Writing To An SQL Database

Apr 16, 2007

Can someone advise if there is a delay in data being written to the database following a tableadapter.update(datatable) command?

I save transactions which are subjected to the above and then a listview is updated to reflect them.

As I work through all is OK and the transactions appear in view.

I then run a backup through my app using a backup object to do this and this reports all OK

I then close the app and re-open and as as I am in debug the database is empty.

I perform a restore through my app using a restore object and selecting the backup file I created previoulsy which reports all OK

The retore procedure calls application.restart to allow the app to initialise to the restored data.

The problem is quite a bit of my data in missing from the restore as if the last block I did prior to backup never actaully made it to the database?

I also rememeber noting that at times when the update method is performed the actual timestamp on the physical databse is not updated....until I close the app and return to the designer?

So does this mean then prior to performing a backup I have to somehow force the app to ensure it has written all changes to the databse?

Thanks
