I have a gridview, where I have made autocode using the wizard. However I need a dynamic SQLcommand from server side. I have tried this code, but it doesn't work, it works if I use this code from HTML (setting the sqlcommand in the SQLDataSource. I have deleted the sqlcommand from the HTML and instead I have implemented the code in the page_load event:
Code:
Dim str As String = SqlDataSource1.SelectCommand = "SELECT DISTINCT Beregning.bId, Informationer.Dato,Beregning.bType, Informationer.pNavn, Informationer.pNr, Informationer.Beskr, Beregning.uId FROM Beregning CROSS JOIN Informationer WHERE (Beregning.UserId = @UserId) AND Beregning.uId = Informationer.uId AND (Beregning.bType=@berType2) ORDER BY Beregning.bId DESC"
SqlDataSource1.SelectCommand = str But this code works, when I apply the SQLCommand in HTML:
I have another class that creates the connection (see refined class half way down page) and I believe it connects or at lest I do not hit any of the exceptions in run time.
I would now like to insert data into my database but nothing is updated.
I am trying to follow this example but it is for reading.
I did run "querystring" on the show SQL Pane and it does execute correctly. It inserts data properly as a new row.
a) SqlCommand.ExecuteNonQuery is used for update, insert and delete operations.
Besides the fact that by using ExecuteNonQuery instead of ExecuteReader we automatically know there won't be any query results returned, are there some other benefits/reasons why ExecuteNonQuery should be used?
b) Similarly, if we want a database operation to return a single value, we should use ExecuteScalar instead of ExecuteNonquery ,where with the latter result would be returned via SqlParameter. Is there any particular reason why we should prefer ExecuteScalar over ExecuteNonQuery?
Dim conn As SqlConnection = New SqlConnection("server='h'; user id='w'; password='w'; database='w'; pooling='false'") conn.Open() Dim query As New SqlCommand("DECLARE @investor varchar(10), @sql varchar(1000) Select @investor = 69836 select @sql = 'SELECT * FROM OPENQUERY(db,''SELECT * FROM table WHERE investor = ''''' + @investor + ''''''')' EXEC(@sql)", conn) dgBookings.DataSource = query.ExecuteReader dgBookings.DataBind()
I need to add in an If statement basically saying if the SQLCommand query returns no rows then show a specific label Can this be done?
I want to add array list in sqlcommand.but i don't no how to pass it. My code is.
ArrayList ProductId = new ArrayList(); for (int i = 0; i < ShipmentPackage.Items.Count; i++) { ProductId.Add(ShipmentPackage.Items[i].ProductVariant.ProductID); } select * from TableName where id= ProductId(ProductId is my Arraylist)
What I'm trying to do is load data into a dataset using Repeater in Asp.net Here what i've done in the code behind
[Code]....
and my HTML code
[Code]....
Is this the correct way for me to use Repeater?ie can we use stored procedure to call it There's an error "The IlistSource does not contain any data sources" I'm trying to retrieve data from the stored procedure only just a simple loading
i want to ask how to i set variable in asp:sqldatasource in sqlcommand in asp.net c#.... This is my code
asp.net <dx:ASPxListBox ID="lsAssignToko" runat="server" DataSourceID="SqlDataSource6" TextField="NAMA" ValueField="ID" AutoPostBack="true" EnableCallbackMode="True" SelectionMode="CheckColumn" OnSelectedIndexChanged="lsAssignToko_SelectedIndexChanged"> <Columns> <dx:ListBoxColumn FieldName="ID"/> <dx:ListBoxColumn FieldName="NAMA" /> </Columns> </dx:ASPxListBox> <asp:SqlDataSource ID="SqlDataSource6" runat="server" ConnectionString="<%$ ConnectionStrings:Ora2010 %>" ProviderName="<%$ ConnectionStrings:Ora2010.ProviderName %>" SelectCommand="SELECT ID, NAMA FROM REF_TOKO WHERE ID IN ( :inTOKO ) ORDER BY NAMA"> <SelectParameters> <asp:SessionParameter Name="inTOKO" SessionField="inTOKO" Size="200" Type="String" /> </SelectParameters> </asp:SqlDataSource> c# string dummy = ""; string data = ""; string inTK = ""; string inTOKO = ""; //string inTOKO1 = ""; int pot; for (int i = lsToko.SelectedItems.Count - 1; i >= 0; i--) { string tok = lsToko.SelectedItem.Text.ToString(); data = lsToko.SelectedItem.Value.ToString(); dummy = dummy + "" + data + ","; int index = lsToko.SelectedItem.Index; lsToko.Items.RemoveAt(index); } if (lsToko.SelectedItems.Count <= 1) { inTK = dummy.Length.ToString(); pot = int.Parse(dummy.Length.ToString()) - 1; inTOKO = dummy.Substring(0, pot); } Session["inTOKO"] = inTOKO;
the problem is where in my variable inTOKO consist of couple of value... Example while variable inTOKO = one value success but while value inTOKO = two value error inTOKO = 1101111 => success inTOKO = 1101111,1211321 => not success

I'm using visual studio 2008 and sql server 2005 and everything is working just fine under normal use. However if a user is on a page for a while several minutes with no activity then clicks a button on occassion the site throws the following exception ...
Procedure or Function "sp_name" parameter '@SomeParameterName', which was not supplied
I'm also encountering this error in Visual Studio while debugging the application, in otherwords run the site from visual studio then make some change to the html in VS save the changes and refresh the page.
The error is not consistent nor is the time the page has to stay idle in order for it to occur....
The current sql command object timeout is 30 secs and the website timeout is 30 minutes.
Boss comes in and demands that we change an existing dataload process written in .Net 2.0 to call stored procedures on two different servers rather than just one. In his mind (not a programmer) this should be a short overnight process. We have about 60 different SQL Commands that we need to change and test. Is there a simple way to do this that I can't think of? If there isn't we will use something like replication or database mirroring, which is my preference but is likely to get the cold shoulder from my boss, especially since I have never set these up before. A function that takes a SQLCommand as its argument and then iterates through as set of connections to execute the SQLCommand. Change all stored procs to call the same stored proc on a linked server.
Like this: select * from foo where @nameofdbcolumnprovidedbyparam = 1? Whenever I attempt this with sqldatasource or in ado I get errors such as: Syntax error converting the nvarchar value 'foo' to a column of data type int.
Declaring the SqlConnection and SqlCommand objects in a webform without CodeBehind I am trying to query data from a MS SQL server with a C# web form without "CodeBehind". I want to write the information to a table in the web form's body.
I am having trouble declaring the SqlConnection and SqlCommand objects that connect to the server.
How do you use "using System;", "using System.Data;", "using System.Data.SqlClient" inside the script element of an .ASPX file?
I have a data entry form. the end user supposed to key in the data as integer. if they do not enter. I do not have default value to put. for the text, I will put the space as default value. Since there will be a lot fields, I really do not like to code as default zero while end user load the data again.
Dim iAAGraduate As Int16If Len(Me.txtAAG.Text) > 0 Then iAAGraduate = CInt(Me.txtAAG.Text)End If
I'm trying to determine whether it is better to declare the connection outside with it's own using statement or to create it inside the sqlcommand itself. This is in regards to a single command interaction with the database (no loops).
