I'm trying to update a row in a table in our sqlserver database i created (first time).I am getting this error, and what follows is the code. ExecuteNonQuery requires the command to have a transaction when the connection assigned to the command is in a pending local transaction. The Transaction property of the command has not been initialized.

I'm just wondering if anyone has come across a good, easy method for updating a SQL Server 2000 DB table using the edit feature in GridView. The catch here is that I need it to encrypt, send to database, then decrypt when the page calls it to be displayed. I have successfully implemented an insert method using FormView with encryption. For some reason, I just can't seem to figure out the edit/update.

I need to display a single field from an sqlserver table, do I need to use sqlDataSource ect. or is there a simpler way (like msaccess's LookUp) for single values.
I have a weird thing happening. I have two identical databases installed on one virtual machine but under two different instances of SQLServer. For some reason, periodically when saving from one it will save to the other instead. Using debug, I have verified that the connection string is correct and when the item saves, it still saves to the wrong database.I use session variable, and am of the belief that it might have something to do with it...and t hat when I go from one to the other it is still getting the connection string form the other for some reason.To make sure that it isn't a problem, I make sure that I completely close out one database before opening the other in a new IE window.I assume that when I completely close out an internet explorer window that it abandons all session states. Is that true?
View 7 Replieswhy this update is failing? The table is connected to OK and there are appropriate values in the parameters to the subroutine, and yet the record in the table remains unchanged. I am using exactly the same code (with different parameters, obviously) to update another table and this continues to work fine.

I have an asp.net application using visual studio express 2008. On one of my pages I created a dataset from one of my database tables. I am able to delete rows and add rows to the new dataset table. I then have a button and on the click event I use the commandbuilder to update the database table. The database table updates with new rows but the deleted rows are not carried out and I can not figure out why desite spending several hours on google to resolve this issue?
Here is some of my code:
Protected Sub Button_updateDatabase_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button_updateDatabase.Click
Try
'I have created a session variable for my data adapter
Dim commandbuilder As SqlCommandBuilder = New SqlCommandBuilder(Session("Adapter"))
Session("Adapter").UpdateCommand = commandbuilder.GetUpdateCommand
Session("Adapter").DeleteCommand = commandbuilder.GetDeleteCommand
'I created a session variable for my dataset
'This update command updates new rows to my database table but not deleted rows
Session("Adapter").Update(Session("CalendarDataset"), "Name")
Catch ex As Exception
Response.Write(ex.Message)
End Try
End Sub
I am trying to track members volunteering. I have a table that has all our members information and another table I want to update what they volunteer for throughout the year. I have a ddl that they select a last name and it populates first name, last name and spouse in a formview. This all works. There are a couple of other textboxes that need to be filled out. When I try and run an update into the volunteer table I get no errors and page shows the meber was updated. However, when I go into the volunteer table, there is no data.
[Code]....
I don't understand why it is not updating into the table. Especially since I am getting no errors.
I have a form in which I display data from a database table, change the data and then update the database table. The form consists of textboxes, so all data displayed in the form is string. However - one data is int in the database table (the rest is varchar), so I need to convert it from string to int when I update the database table. How do I do it?
[Code]....
And, strangely enough, the same code doesn't work with parameters. How is that?:
[Code]....
[Code]....
I have stepped through this code to test it and I am puzzled as to why the update isn't going through to the DB. When I run the SQL statement in SQL editor it updates fine. All variables are getting the proper values when I step through.

Im using Visual Web Developer 2010 Express and have put together a custom form using ASP controls and labels.
I now need to update an access database with the data that is captured on the form. I have added an AccessDataSource but do not know how to link the fileds to the fileds within the database so that when I click submit it updates the table.
[Code]....
Dropdownlist is not updating the table
In general, If multiple users thru an application try to update the same tables in database simultaneously, then by default on what basis the priority will be given.Like if we don't have any extra logic for the locking implemented.
View 3 RepliesI m getting following error in my eventvwr . I couldnt find reasons of the following error.
"Transaction (Process ID 110) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction. "
The only thing my page is doing is inserting/updating data into a table in sql and the thing I can think of is because multiple users are using the same page to insert/update data? Will that cause deadlock?
There seems to be something wrong with the create user wizard?I am using hashed password storage. When I change it to clear storage I see the user's password is being stored as something completly different than what they typed in.Example: changeme1 now equates to something like: 4W*KQQ4%=SIf I use 4W*KQQ4%=S as the password to login with it works but changeme1 does not.When I use the reset password wizard it updates the password just fine and it works when I login next.Any clues what could be causing this?
