DataSource Controls :: Update Table Not Working?
Jun 3, 2010
I have a sproc that updates data in the table but I'm having difilulties with one of the params that is of type datetime. In the sproc, a decision is made based on this date such as if the date is null/blank/emplty, update data, else delete data. I've tried things like
if(@Date_returned IS NOT NULL)
if(NOT @Date_returned = '')
if(@Date_returned = '')
if(@Date_returned > '01/01/0001')
but it always defaults to the "else" part where it deletes my data. The date is passed to the sproc from a .net calendar form object via a bll/dal and I can track the variable with its value. When I actually pick a date it has the date I've picked, otherwise it has a devault value of "01/01/0001 ....".
How should ckeck for this condition?

This query works perfectly on the query analyser.
But when configuring the Table adapter ,I try executing the query and i get 0 rows affected.
What could I be getting wrong in this case.
NB:Existing GalleryID has been supplied.

I'm sure this has been answered many times already, but I still can't seem to find exactly how to search for this issue, so apologies in advance.
Anyway, I have a VB script for entering a row of data into a table by a web user. When this row of data is entered, I wish to take some of the values from the columns of the "primary" table, and have that data automatically create a new row of data in a "secondary" table. I think I'm part of the way there, here is my script:
[code]...
"ProductsByMfr" is the "primary" table - the table that the user adds data into when the button click event is fired.
"DealerPricing" is a "secondary" table that I wish to have some of the data from the newly-entered row in ProductsByMfr copied into. Am I even close here?

I am not sure if I am in the right spot here because this really doesn't have to do any datacontrol but hopefully somone can give me a hand with this.
Basically I have a bunch of TextBox controls on a page that are displaying the data I want but when I try to run an UPDATE query on the record I get nothing. The record values don't update and I don't appear to get any exceptions.....I am actually kinda really baffled on this one, here is what I have for the update code: [Code]....
Btw, if there is an easier way to do this with a control I am up for suggestions as I am just going off of some of my old VB6 ways

The users of my webapplication are validated using database connection. This requires each user is a sql server database user. While logging their validity is checking by trying to create a connection using userid and password entered by the user. If connection opens successfully, it is a valid user. I also have a page in application to change the password, where sp_password is used to updated database password.
string connectionString = ConfigurationManager.AppSettings["DBServerName"];
//try to create a new connection dynamically using user id and password
connectionString = connectionString + User ID=" + userId + ";Password=" + password;
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
}
The problem is after i change password, and logout and try to login, i am able to login using old passwd also. The line of code which creates and open connection succeeds with both old and new password. If i stop and run the application again this works.

I have a form that gets populated by LINQ and I want to be able to update the database using that same form. The form is populated by grabbing a querystring (for example, "edit=10") and searching the primary key for that record. So far so good. I have a button attached to the function below which is supposed to use LINQ to update the database with data from the form. I get no errors, but for some reason, it is only updating one field (Last_Updated) instead of all of them.

I'm trying to figure out how to update multiple rows in my Directory table, when a user changes their Street Number or Street Name in their profile. They can add multiple users to a directory and each user they add to the directory has this primary users UserId in it. So if the primary user changes their address, I want it to update the address for all the users they listed in the directory as well. I'm adding this to the On_Click in the Code Behind, so when they click to update their profile, it fires this function as well. This code may be way off, but here's what I have right now:

I have been able to successfully read a row of data from an SQL table using two column parameters. Now I would like to update this row with new information. Is this possible since the reader does not specify which row was read with the 'reader.Read();' command?

I want to Update Column of a Table where ColumnName will be DropDown.SelectedValue. Example: A set of RECORDS will be displayed from a Customer Table where CUstNo ='1234' and City= 'Chicago' and Grade ='B' Once displayed I want to Update the grade to 'A' of all those customers from the above criteria. In My case I have like 100 Columns, so in where Clause Column Names will be selected from a DropDown. In My Query, Update Customer SET ColumnName= 'some value' where ColumnName ='ActualValue' So how can I pass the ColumnName which is Dropdown Selected Value. I believe I can't give as Update Customer SET DropDown.SelectedValue = 'some value' where DropDown.SelectedValue ='ActualValue' how can I resolve this ?...

I select few columns from table A in dataset. Example "EMP_ID","Name","Address","Phone_Number". I want to save data in this dataset into some other table B.
I want to save data from dataset into table B. But i want to have following functionality
1. Before saving a record from dataset to table B if that record if previously present in table B, if yes then check if any value are different, if yes then update that record with the record from dataset, if all the values are same then leave the records as is.
2. If the record is not present in table B then insert it new records in table B from dataset.
Is there any efficient way to implement in .NET C#.

I am trying to use SqlDependencyCache buthave come across a problem that I wouldn't have thought was unique. We have a InformationDatabase which uses a combination of its own tables and views to other databases on the same server. One of these views points to our HRDataWarehouse database. My stored procedure obviously uses this view to get its information but because the table change is happening on the HRDataWarehouse table the notification is not being sent to my app and as a consequence the cache is not removed.
Is there a tidy way of doing this or do I need to create a trigger to update a table in my informationdatabase and then have a listener on this with a removecache callback delegate added to the cache object?

I'm trying to figure out if it's possible to use an ObjectDataSource Update method with a table-valued parameter. Here's my ODS:
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
DataObjectTypeName="TestProject.MyTestDataTable"
SelectMethod="GetTestData" TypeName="TestProject.BLL.TestBLL"
OldValuesParameterFormatString="original_{0}"
UpdateMethod="UpdateTestData">
<SelectParameters>
<asp:Parameter DefaultValue="65" Name="testId" Type="Int32" />
</SelectParameters>
</asp:ObjectDataSource>
I bind this to a GridView but I'm not looking to edit row by row. Instead my GridView has a bunch of TemplateFields with textboxes. I also have a Button that when pressed, invokes the Update method of the ODS. So then the "UpdateTestData" function in my TestBLL is called. This looks like this:
public void UpdateTestData(MyTestDataTable dt)
{
QueriesTableAdapter qta = new QueriesTableAdapter();
qta.UpdateTestData(dt);
}
At run-time in debug, it seems like the object for the signature above is not populated with the data from my GridView.

Since I was not able to figure out my previous problem I decided to go ahead and make my own update statements and change the update command on a datasource I have. So I have a few textboxes and whatnot that allow you to change data and then click an update button. When I click that update button the page seems to refresh as if it was updating the record but the data in the boxes reverts back to what it was. I also created a ONUpdated sub and the label text change does not show.
