SelectCommand="SELECT [kpnr], CONVERT(varchar(4),[kpnr]) + ' (' + [kpnamn] + ')' As kpnamn FROM [kpstandard] WHERE (([kptyp] = @kptyp1) OR ([kptyp] = @kptyp2)) ORDER BY [kpnr]">
What I'd like to do is to get the two variables Kptyp1 and kptyp2 directly from the .vb file, either to the SELECT statement, or at least to the controlparameter code, instead of having to go through two hidden fields.
Can anyone help me out with using parameters in my SqlDataSource? I have my UpdateCommand set as follows: UpdateCommand="UPDATE Custom_ContainerRequest_ESTWEIGHTS SET WEIGHTRANGES = @WEIGHTRANGES WHERE ESTWEIGHTS_ID = @original_ESTWEIGHTS_ID" <UpdateParameters> <asp:Parameter Name="WEIGHTRANGES" Type="String" /> <asp:Parameter Name="original_ESTWEIGHTS_ID" Type="Int32" /></UpdateParameters> And the application is just hanging when I run it. (No error message.) If, however, I hardcode the values instead of using parameters, it works just fine everytime. UpdateCommand="UPDATE Custom_ContainerRequest_ESTWEIGHTS SET WEIGHTRANGES = 'test' WHERE ESTWEIGHTS_ID = 1" So I don't know if it's a single-quote issue, or if there's some other syntax I need, or what. One last note is that this is a DB2 database I'm using. But I'm sure that my connection is valid because I can read and update data...only not using parameters. Any help is greatly appreciated. Thanks,Billy
Hi I need to create an sqlDataSource that filters a table based on the users ID – in other words, I have a table with a list of users, and when a logged in user loads the page, the results should only show records with their user name. How would I do this? Thanks for any help in advanceRichard
I am setting the SelectCommand of the SqlDataSource in my page_load. This is the WHERE part of my SelectCommand:WHERE ProductName LIKE '%' ? '%' OR ProductRef LIKE '%' ? '%'The above uses two select parameters. But the two select parameters will have the same value. So is it possible to re-write my select command so it just uses one parameter? I have tried the following, but this doesn't work. WHERE (ProductName OR ProductRef) LIKE '%' ? '%'Is there similar syntax I could use that works?
Hi, I need to UPDATE the IP Address of a newly created user into a table (the value is currently set to default - " Not Available"), and I really dont know the syntax required to do this. So far I've derived all the variables needed using the following code: protected void ContinueButton_Click(object sender, EventArgs e) { //Get the ip address and put it into the customer table - (the instance of this user now exists) MembershipUser _membershipUser = Membership.GetUser(); Guid UserId = (Guid)_membershipUser.ProviderUserKey;<--------------------------------------------------------------I can see the UserId here if I pause the prog SqlDataSource customerDataSource = new SqlDataSource(); customerDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString(); customerDataSource.UpdateParameters.Add("IPAddress", Request.UserHostAddress.ToString());<---------------------------------------I can see the IPAddress here customerDataSource.UpdateCommandType = SqlDataSourceCommandType.Text; what next I've not got a clue as to what to write next. There is a try / catch statement after this using : rowsAffected = customerDataSource.Update(); which remains at 0 no matter what I try. Any help greatly appreciated.
What is the C# code I use to do this? I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
I keep receiving the following error whenever I try and call this function to update my database.
The code was working before, all I added was an extra field to update.
Exception Details: System.Data.SqlClient.SqlException: Incorrect syntax near the keyword 'WHERE'
Public Sub MasterList_Update(sender As Object, e As DataListCommandEventArgs)
Dim strProjectName, txtProjectDescription, intProjectID, strProjectState as String Dim intEstDuration, dtmCreationDate, strCreatedBy, strProjectLead, dtmEstCompletionDate as String
Dim myConnection As New SqlConnection(System.Configuration.ConfigurationSettings.AppSettings("connectionstring")) Dim cmdSQL As New SqlCommand(strSQL, myConnection)
Forgive the noob question, but i'm still learning SQL everyday and was wondering which of the following is faster? I'm just gonna post parts of the SELECT statement that i've made changes to:
INNER JOIN Facilities f ON e.Facility = f.FacilityID AND f.Name = @FacilityName
OR
WHERE f.Name = @FacilityName
My question is whether or not the query runs faster if i put the condition within the JOIN line as opposed to putting in the WHERE line? Both ways seems to return the same results but the time difference between methods is staggering? Putting the condition within the JOIN line makes the query run about 3 times faster?
Again, forgive my lack of understanding, but could someone agree or disagree and give me the cliff-notes version of why or why not?

hi all, in all my 2.0 learnings and books i keep coming across the page element <asp:sqldatasource>. I have always (in 1.1) used server side connections and adapters to bind my Sql datasets to any control needed. Now that im learning 2.0 im finding it difficult to understand using control on the page to bind my data. Can someone explain the benefits of using this data source? Ideally i would like to keep my data access layer separate from my presentation layer but i'd really like to understand why this method seems so popular. thanks in advance, mcm
Hi, I am new to ASP.NET 2.0 and I am trying to use VWB to bind my web site to a SQL Express edition. I used SQLDataSource to specify the .mdf file so I can connect to my tables but when I click on the advanced button to generate the Insert, Update, Delete SQL I find it grayed out and it cannot be clicked. I looked into several tutorials online and I couldn't find the problem, can anyone explain what I am missing or doing wrong? Any suggestion is very appreciated. Thanks

Hi, I'm trying to go through a checkbox list and inserting them into a database using a sqldatasource with the following code:For Each li As ListItem In Locations_Checkbox.Items If li.Selected = True Then

End If Next When more than one checkbox is ticked, I'm getting the error 'The variable name '@ProgrammeID' has already been declared'. How do I close or reset my Datasource before I try and use it again? Thanks for your help
Hi, I want to know when to use an sqlDataSource object because I used to populate for example a listBox control in visual studio net 2003 from AQLK server database by using a connection object, command object, dataAdapter object and a DataSet object. I discovered if I use sqlDataSource object (using visual studio net 2005) ,all I need is to write the connection string and a Select statement as properties for that sqlDataSource, so why to use the above mentioned objects(connection,command,adapter,dataset) while I can access any database in sql server through the use of sqlDataSource? I appreciate if you can explain to me the difference and when to use an sqlDataSource thx
Hi, I have an application w/ n-tier design so I've never used the SqlDataSource up to this point but having to do my own sorting for GridViews is not something I want to keep dealing with. I'd like to take advantage of some of the packaged features too. My question is: are there any purists out there who opted to use SqlDataSource. If so, what do you think about it? It's nice that SqlDataSource makes things simple but having data classes and dealing w/ exceptions in those classes certainly make an application pretty robust. Should I entertain the idea of using SqlDataSource or stay as a purist and keep doing things the old fashioned way?
Hey all,I've just started to use asp.net and so far have found it fairly easy. The only problem I've come across is with putting variable clauses into the SqlDataSources.This is one example of what I've done trying to get this to work. <asp:SqlDataSource ID="ClaimsDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>" SelectCommand="SELECT TOP 20 dbo_ClaimStatus.ClaimStatus, dbo_CLAIMS.PACKET, dbo_INSURED.NAME, dbo_FEES.INSURER, dbo_FEES.CLAIM_NUMBER, dbo_CLAIMS.LOSS_DATE, dbo_CLAIMS.RECEIVED, dbo_CLAIMS.LOSS_LOCATION, dbo_CLAIM_TYPES.CODE FROM ( ( ( ( dbo_CLAIMS INNER JOIN dbo_CLAIM_TYPES ON dbo_CLAIMS.CLAIM_TYPE = dbo_CLAIM_TYPES.CODE ) INNER JOIN dbo_ClaimStatus ON dbo_CLAIMS.StatusID = dbo_ClaimStatus.ClaimStatusID ) INNER JOIN dbo_FEES ON dbo_CLAIMS.PACKET = dbo_FEES.PACKET ) INNER JOIN dbo_INSURED ON dbo_CLAIMS.PACKET = dbo_INSURED.PACKET ) WHERE dbo_ClaimStatus.ClaimStatus = @claimStatus"> <FilterParameters> <asp:QueryStringParameter Name="claimStatus" QueryStringField="ctl00$MainContent$claimStatus" /> </FilterParameters></asp:SqlDataSource>I'm posting claimStatus from a previous page using PostBackUrl on an <asp:Button /> tag and claimStatus is an <asp:DropDownList /> tag.Any idea's as to why this doesn't work?Nalum
Dear Friends in my project , i' ve used two SqlDataSource, one button and one gridview control; the process that i want to do is when i click the button control ,according the if structure in this button control ; one of the SqlDataSource control assign to the gridview control DataSource property (but i assign the DataSourceID property for the gridview , it runs); but i couldnt do it, what can i do for it? (my code doesnt give any errors but doesnt do anything too) my code is here; protected void btnSearch_Click(object sender, EventArgs e) { if (txtSearch.Text != null){ SqlDataSource3.SelectParameter["key"].DefaultValue = txtsearch.Text; Gridview1.DataSource = SqlDataSource3; GridView1.DataBind(); } else { SqlDataSource1.SelectParameters["keySession"].DefaultValue = cbSession.SelectedItem.ToString(); SqlDataSource1.SelectParameters["keyClass"].DefaultValue = cbClass.SelectedItem.ToString(); SqlDataSource1.SelectParameters["keyUnit"].DefaultValue = cbUnit.SelectedItem.ToString(); Gridview2.DataSource = SqlDataSource1; GridView2.DataBind(); }

Could someone help me with syntax? Everything works until line 23. At that point, I get a NullReferenceException. When I examine the SqlDataSource object, everything inside reads "Object cannot be null" or "The pointer for this method was null." The SQLDataSource looks ok, just before executing line 23. Does anyone have a complete example of how to do this ADO operation?
