Dim SQLData As New System.Data.SqlClient.SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True")
Dim cmdSelect As New System.Data.SqlClient.SqlCommand("SELECT TOP 1 Name FROM Table1 Order by Id DESC", SQLData)
SQLData.Open()
Dim dtrReader As System.Data.SqlClient.SqlDataReader = cmdSelect.ExecuteReader()
If dtrReader.HasRows Then
While dtrReader.Read()
TextBox1.Text = dtrReader("Name")
End While
Else
Response.Write("No customer found for the supplied ID.")
End If
dtrReader.Close()
SQLData.Close()
I am getting the following error when I try to update my record in a GridView. I am using a DataObjectSource and its grabbing the update from a DAL. This is the error:Index (zero based) must be greater than or equal to zero and less than the size of the argument list.This is my code where it says the error is:
I am having a problem with setting a flag on sucessful completion of a record in a stored proc. I am using following code. stored proc: Update where condition.
if @@RowCount=1 update table set ItemReviewed=1 where condition..... select @Count=@@rowcount
here the problem is i do have 2 update statments in a single proc..if one is sucessful then its setting if others failed...I want to check both are sucessful. @count will return the bool to my code where i can move on to the next record. if some testing @@rowcount is not feasible one to use...Itemreviewed is bit field.
Im trying to update my DB(DataBase) by using SQL UPDATE query ,but its not updating in the dataBase i receive confirmation(in testLabel) that one row is affected(dataReader = query.ExecuteReader(); return numbers of rows affected)...
I have given a HTML editortext control on a page,which generates HTML (i have to store it in my DB,that page is only for Admin) ,on pressing Update button , im receving in my testLabel that one row is affected(which shows DB is updated succesfully) but when i check my DB its in old state,it is not updating...
Here is my Event handler of Update Button which have to make updates in DB:
I can't for the life of me remember how to do this and I'm sure someone will answer this pretty quickly. I need to insert or update a record based on if it exists so in the SP I need to do:
SELECT * FROM table1 WHERE LinkedID = @ID Then I need to check if any rows were returned and apply it to an if statement which is where my mind is blocked.
I'm having trouble with an SQL statement. I want to have one statement that checks to see if it a record exists. If it does, then update it and if it doesnt then insert a new one in the server. Here is what I have so far:
I am having problems with the following update query that is part of an SQL Datasource. This query was automatically generated by VS2008 and I have formatted it so that it is easier to read.
Everything works but the [ZIP+4] field which does not update. I believe that VS2008 added the square brackets around the field name because of the plus character that it contains. If I change the ZIP+4 variable name to [ZIP+4] = @ZIP4 it still does not work. This brings up another question, I have never understood where these update queries are getting their data from.
I am looking for simple asp.net code example showing a simple webform task.
When user clicks a button, a stored procedure fires which runs an update-table query (not pulling any parameters from the user) and returns a count of the number of rows that were updated when the query was run.
Within my stored procedure I have the parameter @RowCount=@@ROWCOUNT.
All sample data I have found online has been C# or VB, but nothing that I can apply to my asp.net program.
Again, this is a simple task that for whatever reason I cannot find examples of online.
I have a website where i already have User / Roles mechanism. What i am after is the if user update certain record i will include his username against that record thats easy enough. But if that row have multiple coulmns i want to save which coulmn he/she updated?How can i compare old and new data have save this information?
I have a function that checks for a username and if it finds the username it will allow the user to update the user, there are 3 main columns: Name,Age,isFemale. I have the enduser supply the information and then I try to update the record but I get a sql error for "not a valid" column.console app:
[Code]....
I pass the spIsFemale by using an enum, here is the Person Class with function. [Code]....
I get an error that column isFemale is not valid. The isFemale column is a bit type. If it's a 1, it's a female, if 0 male. this is more of a test area and I'm trying to update records or create new one's if the name does not exist.II am new to C # and I am just trying to learn new ideas and methods within C sharp.
I have a vb.net page that has an optional parameter. If a user enters data for that field, and clicks save, it saves fine via the stored procedure. HOWEVER, if the user changes their mind, and wants to erase the data they entered, they go to the text field, and delete the characters, and click save, but no matter what, the stored procedure will not save the fact that they erased the data (it won't set it back to NULL). If the user enters a space, the stored procedure will save the space, and if they enter different data, it will save the other data. I can't figure out how to get it back to letting them set it to Null? I think this is because it's an optional parameter, and the stored proc is used by several forms (Some of those forms do not include this parameter), but this form utilizes that optional paramater.
I use the following coding to show a form for receiving the original record and it works:
[Code]....
And then I set the controller for edit page as the following:
[Code]....
Although it does not show any error and return to the index page, it cannot update the record because I can see the original record in the index page. Is there any mistakes I made?
I have tested the record insertion and it works. Therefore, I think it is not the problem on the database write permission.
I've been playing around with MVC lately, and was wondering how you could do this:
I have a view that displays a list of products, and against each product is a list of categories (in a combobox). I'm trying to find out how you can update a product's category when you select a category in the list. I know you could do something fairly simple with jQuery, but I'm trying to understand how submitting forms works with MVC.
Here's what I currently have:
[Code]....
But I'm not sure how to tell the controller what product needs to be updated when the form is submitted.
I clicked the edit link button the "test" will shown in the textbox.I am change to "testing" and i will click the Update button.But it store in test.i update datetime also.The datetime has been updated..How to i update the record?..
Reason: The Form again post.So i enter with the "state=edit" and the data retrieve from the DB i will shown in the Field.After the Updation function is working.So the textbox value set into the DB value.
