ADO.NET :: Unable To Insert Value From Dataset Into Sql Server Database
Nov 30, 2010
I have this code :-
[Code]....
But the result is it only insert the first row of the HQDS dataset...then it will give this error :"Violation of PRIMARY KEY constraint 'PK_BRANCH'. Cannot insert duplicate key in object dbo.TS_BRANCH'.The statement has been terminated.
If I comment this line : Destadapter.Fill(HQds, "Testresult")
It doesn't give any error and also it doesn't insert anything to the database.
Violation of PRIMARY KEY constraint 'PK_TS_BRANCH'. Cannot insert duplicate key in object 'dbo.TS_BRANCH'.
I am using DataAdapter.FillSchema to create shema of tables in DataSet. I created DataRelation on columns T1id in both tables.
Now when i try to Update Sql Database T1id in Table2 remains 0 and not the value of T1id in Table1.
I can successfully update Sql Database if i fill DataSet with records first (Using DataAdapter.Fill), but that's not what i want to do. I don't need "old" records in my dataset. I want to use dataset just to store all imputs from user until the proccess is done and then insert all those records "at the same time".
i need to insert multiple rows at a time into database table(sqlserver) from datatable or gridview. Actually iam looping through the rows of gridview and inserting each row. Is there any method to insert entire table of rows at a time into database table. Both datatable columns and database table coulmns are similar.
I'm currently developing a website using VS2010 Express/SQL Express 2008, and am using the applications development server to test.
I have created an access layer which effectively takes all my cachable data and creates datasets.
I've also created a system wheras for each dataset, For each dataset I also create a token cached object (a string), which is set to expire before the dataset. The theory behind this is that when my token expires and is removed from cache, it calls a routine to rebuild the dataset, and re-caches the new result, then creates a new token. Think of it as a poor mans SQL dependency.
What this allows me to do is rebuild datasets behind the scenes with little interruption/delay throughout the day. It all works great - for instance when a user updates a table containing 100,000+ records on the site, the dataset rebuilds at hourly intervals reworking and consolidating the data in the background before representing it in a smaller cachable form.
What I would like to know is this. If I was to replace the database during the usable day (only updating the tables that users don't update), lets say adding 50 new records, would it cause the cache to be dropped. The reason I ask is because it the cache remains until its exipry time, I can replace the database and rebuild datasets incorporating new data in the background when the token expires. If the cache is dropped when I update the database, it will mean interuption whilst I reload the datasets and will change my strategy on uploading new data.
I ask the question because I'm currently working on the development server and unable to test in a live server environment at present.
i am trying to restore database.bak in sql server 2005 (i know the database.bak was also generated in sql 2005 server)
i am trying to restore back up database .bak into the new database i just created in sql server 2005i have saved my database .bak into c drive and when i select database .bak "From Device", it doesn't get populated in the list below and i see nothing and it keeps on prompting a message"You must select a restore source"
Here's the screen shot: (i tried restoring database in sql server 2008 and it was sucessful but i am facing this problem in sql server 2005 only)
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?
I am reading xml file using dataset.readxml() method. after this i want to send this data to the database. I want c# code to create a database in sql sever and push watever data in the dataset to that created database.... i am dealing with many xml documents. some could be of same format.. lets say... if 2 docs of same format exists... then it shud not create new database or new tables.. it shud push the data to the suitable format...as i am a newbie its a bit confusing for me... i dont even have any idea on how to proceed with this.
in above SP I define that if users tell or Mobile number was in Estate_free ro Black_list table it doesn't insert data into database and show 'You can just register 1 Time' and if there wasn't their mobile or Tell in those table it insert their data into Estate_free table and show 'You have been registered'.
problem is that when I enter data in database with new mobile number it didn't insert data in database and show 'you can just register 1 Time'.

I have some issues about retrieveing and storing date information to my database (ms sql server 2005).My data column is a DateTime, and i have set my web.config globalization culture is set to "en-gb"
When i retrieve date from the datebase it appears as dd/MM/yy, that's fine. But i cannot insert a new date as same format?! It will only accept MM/dd/yy or yy/mm/dd.Right now i'm using this code to correct the error:
[Code]....
Is it possible to change the date format on the database or something, so i dont need to use this code?
I have a form wilh couple of Drop downs and text boxes and a Data Grid View which displays data from Access Table. When I hit add button on the form, I can see the data being added to the Grid View. But when I close the form and open the Access Database File (.mdb), the respective table is empty. The Access Table is not being updated. Second time if I open the form, the Grid View is also empty.I am pasting my code here.

Just beginning to set up and get into MVC and I have immediately run into a problem...
I opened a new MVC project in Visual Studio 2008 Pro, tried to run the basic template project, chose the logon/register page, enterered my details and got a runtime error message in AccountsModels.cs:
Unable to connect to SQL Server database Do I need to download a db from somewhere first, have I missed a step out the install ?
I am using Visual Web Developer 2010 Express on a web server. On the same network I have SQL Server 2008 Express installed on an SQL server.
I have created a login for my web server in SQL Server like mydomainmywebserver$.In Visual Web Developer when I use Database Explorer to add a connection I am having a problem. I can see my SQLserver in the server name box but I don't any database in the Select a database name box.
What is the likely reason for this? Is it an authentication problem in SQLserver?
I 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.
Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. make sure the user has a local user profile on the computer. The connection will be closed.
After I formated my system, When I run my website on local IIS databases, aspnetdb.mdf don't seem to work. But works fine on local Cassini (VS).
But this problem is only with one of my new website , rest everything work fine.
Does it have anything to do with SQL Managment Studio? I din't take any backup of master database and all.
I have a ASP.Net program written in C# that uses a database stored in the AppData directory, the program works perfectly on my development (Win7SQL 2008R2) when I deploy to a Win2008R2SQl 2008 R2 server the program is unable to connect to the database. I'm using the connection string below. Several sites suggest I set the Application Pool to use 'Network Service' as this has Modify permission to the AppData directory, I have done this but it still won't work, another site suggested I Application Pool to "Load User Profile = True" but still no joy.
[code].....
I get "Object reference not set to an instance of an object." in my app and "An attempt to attach an auto-named database for file C:inetpubwwwrootADPhonebookApp_DataDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share." in the Application Event Log
I am using VS 2010 Professional with SQL Server 2008 Developer. I right click on the App_Data folder in solution explorer and add an existing item, then navigate to the correct database. However, I receive a pop up that Access is Denied. How do I fix this?
