I would like to use a command parameter to concatonate two fields
protected void Notes0_Inserting(object sender, SqlDataSourceCommandEventArgs e)
{
e.Command.Parameters["Comments"].Value = Eval("LeadID")&" "&Eval("TextBox1");
}
Where the leadID is based on a query string and comments are entered in textbox1
I'm linking a form to sql database, As far as i know for textbox the code will be like this one below in VB:
dashDataSource.InsertParameters.Add("databaseColumName", NameOFTextBox.Text)
But what is the code for a drop down menu for countries list?
I have an SQL datasource that successfully enters customer details into a table. What it includes is the persons address. First of all we add the persons address, then we add the persons name to that address in a seperate physical procedure. i.e. on a different form.
What I need to do is try and stop users entering the same address twice. The way I have thought of doing this is by making a string field called AddressIdentity and have this contain the door number and the postcode of the address with all the spaces stripped out. Then when adding the address, it checks if this exists before adding it. However I cannot work out how to put the 2 fields together without using the codebehind file, which I don't mind doing if I need to, but I'm sure its avoidable.
Here is my code - I have only included the relevant parts:
InsertCommand="INSERT INTO [tbl_shop_client_addresses] ([FlatNo], [Address1], [Address2], [Town], [County], [Postcode],
[Country], [Telephone], [DoorNo]) VALUES (@FlatNo, @Address1, @Address2, @Town, @County, @Postcode, @Country, @Telephone, @DoorNo)"
<InsertParameters>[code]......
So how do I do it? I was trying:
InsertCommand="INSERT INTO [tbl_shop_client_addresses] ([FlatNo], [Address1], [Address2], [Town], [County], [Postcode],
[Country], [Telephone], [DoorNo], [AddressIdentity]) VALUES (@FlatNo, @Address1, @Address2, @Town, @County, @Postcode, @Country, @Telephone, @DoorNo, @Postcode + @DoorNo)"
but of course AddressIdentity is a string. Do I use ' ' marks with an & sign? Or can't I do this?? Maybe I need to use the codebehind anyway to see if the field exists before inserting it?
How do I view my parameters items ?
I tried this but got this error

I'm using Enterprise library, but the idea is the same. I have a SqlStringCommand and the sql is constructed using StringBuilder in the forms of "insert into table (column1, column2, column3) values (@param1-X, @param2-X, @parm3-X)" + " ";where "X" reprents a "for loop" about 700 rows like so
[Code]....
So after all is done, I have 700 insert statements in one batch and of course, I did another 700 loops and added the values to those parameters. It runs fine and fast for a few days. However, last night, suddenly I get this error

I want to issue an INSERT command for an SQL Server table using DataAdapter without first issuing a SELECT command. Could anybody send me lines of code to handle this? Also how do i manage INSERT into selective table columns (I have 10 columns but i only want to update 2 of them)?
View 2 RepliesI have a asp.net gridview control on my page with several fields and a couple of command fields. However, the update command is giving me problems.
Here is what works. The update command works provided I put straight text into the textboxes that appear. I even have one field that contains a dropdown list which works fine.
Here's the problem. I have two fields that need to access their value programmatically. These fields will reflect the current datetime and the current loggedin user from active directory. I have already created public strings in the C# code.
When I run the edit command on the asp form the grid uses one "DataKeyNames" element. With this the grid can update the selectedrow. However, I haven't been able to access it programmatically in the C# code. I can access the selectedrow in the "selectedindexchanged" event but then I am not able to update my fields in the gridview itself. So, part one of my question is how to I access the "DataKeyNames" properties of a gridview control.
if I can't access the "DataKeyName" property perhaps I could set the label nested within the gridview to the "myCurrentUser()" public string. I am inserting my code to hopefully make this clearer.
I have visual 2010 with net 3.5 web app. I was implementing EntityFramework in my project and added a gridview to a entity source control. It worked ok, with select, update, and delete buttons enabled on the grid. But then, i needed to add a template field bound to a Foreign table, so my users select value from a list instead of writing the code. After that, my app fires error when i delete. I tried everything, inclue dakeyNames, write code on my RowDeleting, RowDeleted, RowCommand, but error persists.
Now, i can delete the row, but it then i get the error Object reference not set to an instance of an object If i implemente delete code on RowCommand i get the error: Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries.
I'm creating a confirm delete like popup with an iframe to use along with a gridview. When you click delete on a gridview row, the iframe shows up and asks if you would like to delete the associated image as well from the server. It works perfectly the first time I delete a row. After that whenever I click select or edit on a new row, it calls the rowdeleting event from the last deleted entry every time. I'm stumped.Here's the Sub:
'// Event that Occurs when the Delete Button is Clicked //'
Protected Sub Confirm_Delete(ByVal sender As Object, ByVal e As GridViewDeleteEventArgs) Handles GridView1.RowDeleting
Dim file_name As Array = Split(GridView1.Rows.Item(e.rowIndex).Cells.Item(10).Text, "/")
If file_name.getLength(0) = 1 Then
file_name = Split(GridView1.Rows.Item(e.rowIndex).Cells.Item(10).Text, "")
End If
Dim fn As String = file_name(file_name.getLength(0) -1)
fn = replace(fn, ",", "%2C")
fn = replace(fn, " ", "%20")
Dim url As String = Me.Master.get_root_url & "CrimeBulletinProject/ConfirmDelete.asp?img_list=" & fn & "~!"
confirm_delete_frame.Attributes.Add("src", url)
confirm_delete_frame.Attributes.Add("style", "display: block; left: 50%")
End Sub

This is the first time I have been working on databases and I am trying to insert data using an object datasource but no data is being inserted and no exception is thrown. I'm not sure where I am going to wrong. I am putting user data into session variables and inserting the session variables into the dataacess class layer and have a try and exception but nothing being thrown. Any help would be really appreciated because I don't know even where to start looking with this or how I can get the error to be thrown. Please see some of my code below to give an idea of what I am doing

How do I use the Update command in GrideView?
I would like to use update command for specific fields in the dataset, but not all fields from database ( or maybe in GridView? )
I have an ASP.NET project which has already some custom fields in it's web.config file. I've added in it three more fields and used them in my changes, and it's working great.
But where it needs to be used, there aren't these thre fields in the web.config (this was expected, I've just added by hand for tests and developing).
How do I check the existance of fields in web.config, and in case of not finding it, how do I add it permanently to the web.config ?
I been reading a bit about SQL injection and I want to be sure my code is lets say "safe" from it, I was planning on using RegExp validators to check the user input but another post in here suggested only using parametrized querys, well Im using them but I want to be sure my code is safe, is it?

When appending parameters to an ADODB.Command should the parameters add to the command text. When I get to the point where it sends to the database the command text of the adodb.command is "{ call PKG_WORKPLAN.ADD_PROJECT(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) }"
I then get a ORA-06502: PL/SQL: numeric or value error: character to number conversion error ORA-06512: at line 1 error. I think i may be getting it from the question mark.
Also is there any way to what sql is inserted if that isn't it.
here is my code for selectiong some records from db table
string strSql = "select * from mtblNBD where SentTo=@SentTo and InternalStatus Is NULL order by DeadLine desc";
SqlCommand com = new SqlCommand(strSql, con);
com.Parameters.Add("@SentTo", SqlDbType.NVarChar, 50).Value = (string)Session["uname"];
here I am using parameters for SenTo field but not for NULL so it is ok... or should I use parameters for this field where value is NULL , if yes then how can I use parameter for this
I am using AS 400 OLEDB with .NET. It uses '?' instead of '@param to bind parameters with a commandNow there is a situation where the command is like
SELECT ...
FROM
(SELECT ...

FROM Employees e
) as DerivedTableName
WHERE RowNum BETWEEN @startRowIndex AND (@startRowIndex + @maximumRows) - 1
Now my command becomes
SELECT ...

MsSQL_ExecuteNonQuery("StoredProc_AddNewMyObject", ________________?)

End Class

I want to know how I could fix the following. I essentially have two almost identical SQL functions and want to combine them into one. The only difference between the two functions is the SQL Command text that is being used. Here is a brief idea of what I have unsuccessfully tried thus far:
[Code]....
I receive no compilation errors, but the exception is thrown and table is not filled. I have a feeling that I am overlooking something obvious.
I want to use parameter in SQL command, Which the following code is better and why?
string id= getId();
SqlCommand cmd1 = cn1.CreateCommand();
cmd1.CommandText = " INSERT INTO std(idStd) VALUES (idStd=id) ";
cmd1.ExecuteNonQuery();
string idF = getId();
SqlCommand cmd1 = cn1.CreateCommand();
cmd1.CommandText = " INSERT INTO std(idStd) VALUES (idStd=@id) ";
cmd1.Parameters.AddWithValue(@id, idF);
cmd1.ExecuteNonQuery();
No matter what I do I keep getting the error that my input string is not valid and that the system cannot convert a string to a double. I have a table with two fields, both are defined as nvarchar(25). My command text is:INSERT INTO OtherProducts VALUES ('Sample','Test') am using Visual Web Developer. This is as simple as it gets. I have tried parameters as well.
