SQL Server :: Updating One Table Pulled From Another?
Mar 2, 2011
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 that has dropdown box and user can either select Store Associate or Store Manager, when they click on either, I have GetASsociate function that pulls data from sql database. What i am trying to figure out how to do, is that if they say select Store Manager I want to filter what data to pull from that sql table that has all associates in it, so I was trying use an 'expression' statement to stay if Store Manager was selected, only pull me back the store managers from that table. Then same thing for if they selected STore Assoicate, then only bring me back teh store assocites from that table. But the expression statment does not appear to be working.

I 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?
I have a website that goes out to multiple clients. Sometimes a client will insist on minor changes. For reasons beyond my control, I have to comply no matter how minor the request. Usually this isn't a problem, I would just create a client specific version of the user control or page and overwrite the default one during build time or make a configuration setting to handle it.
Now that I am localizing the site, I'm curious about the best way to go about making minor wording changes.
Lets say I have a resource file called Resources.resx that has 300 resources in it. It has a resource called Continue. English value is "Continue", the French value is "Continuez".
Now one client, for whatever reason, wants it to say "Next" and "Après" and the others want to keep it the same. What is the best way to accomodate a request like this? (This is just a simple example).
The only two ways I can think of is to
Create another Resources.resx specific to the client, and replace the .dll during build time. Since I'd be completely replacing the dll, the new resource file would have to contain all 300 strings. The obvious problem being that I now have 2 resource files, each with 300 strings to maintain. Create a custom user control/page and change it to use a custom resource file. e.g. SignIn.ascx would be replaced during the build and it would pull its resources from ClientName.resx instead of Resources.resx.
Are there any other things I could try? Is there any way to change it so that the application will always look in a ClientResources.resx file for the overridden values before actually look at the specified resource file?
I am using a handler to pull an image from the database and I need to resize the image while maintaining the aspect ratio.I have seen a few examples, but they were all pulling the image from the filesystem and not a database. This is the code I am using inside the handler to pull the image from the database: [Code].... Can someone point me in the right direction?
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 have a custom class that pulls user information from a SQL Server table. Now that I'm expanding the site from a single page to others. I want to shift the code to the Session_Start event so that the information is always loaded when the site is accessed. How do I call my custom code from global.asax since its script and not a class.
why 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.
Public Shared Sub SaveMathsSettingOptions(ByVal ID As Integer, ByVal Auto As String, ByVal Repeats As Integer, ByVal Weekly As String, ByVal ClassSheets As Integer, ByVal HomeSheets As Integer) Dim con As New MySqlConnection(_connectionString) Dim ret As String Dim sql As String sql = "UPDATE centres SET maths_auto = @maths_auto, maths_auto_reps = @maths_auto_reps, maths_weekly = @maths_weekly, maths_class_sheets = @maths_class_sheets, maths_home_sheets = @maths_home_sheets WHERE centreID = @centreID" Dim cmd As New MySqlCommand(sql, con) cmd.Parameters.AddWithValue("@maths_auto", Auto) cmd.Parameters.AddWithValue("@maths_auto_reps", Repeats) cmd.Parameters.AddWithValue("@maths_weekly", Weekly) cmd.Parameters.AddWithValue("@maths_class_sheets", ClassSheets) cmd.Parameters.AddWithValue("@maths_home_sheets", HomeSheets) cmd.Parameters.AddWithValue("@centreID", ID) Try con.Open() Catch myerror As MySqlException 'MessageBox.Show("Error Connecting to Database: " & myerror.Message) ret = myerror.Message con.Close() Finally con.Dispose() End Try End Sub
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 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?:
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.
I have a gridview which contains a dropdownlist inside a TemplateField. The ddl appears correctly and seems to work ok but it isn't updating the table despite being bound to a field.
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.
my main intention is that, the exsisting table of sql server database(.dbo) with 1000's of records, that should be import to a new access database table(.mdb).for example if we want to had a new table in db2, of exsisting table in db1 with some conditions by using "select * into New_Tabel from (select * from Exsisting_Table where <Condition>) as objectName". Here the new table is created and records inserted in one execution in db2. The same work should be done for access(sqlserver db --> Access db).Here the new access database table with given name (as string_sysdate) must be created dynamically by clicking a button (multiples time creating new table).Is there any query or c# code for sql server database to access database.
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.
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?
I have used this before with no issues. Now I get to the page with the detailsview using parms I pass with the key to the row. When the page opens the row I want to update is displayed.
I am having 2 issues. One when I change any of the fields and hit Update (the Edit button),
all rows are updating not just the row displayed. The second problem is I have an update_date and an Updated_by field with code in code behind in the Onitemupdating event and they are not updating at all. (This bit of code works fine in another page I have to updated similar fields on an insert).
I changed a text field to a template field assigning the selected text and the selected value is being assigned to another currency field also templated. I get aa error
[FormatException: Input string was not in a correct format.]
