Question

ASP.NET Insert Command Parameters

Asked by: noobe1

How do I set the values of the parameters of a insert command? I used SQLDataSource wizard to generate all the SQL queries.

I get the following error when I used the attached code snippet to set the value:

An SqlParameter with ParameterName 'FileName' is not contained by this SqlParameterCollection. 

Protected Sub FileUploadDataSource_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles FileUploadDataSource.Inserting
        e.Command.Parameters("FileName").Value = "New File"
    End Sub

Create a insert parameter on your aspx called "FileName". Your code can stay the same if you do that.

 

by: gocemiPosted on 2008-01-15 at 05:12:44ID: 20662186

start in debug mode,
create brakpoint.
and in one string write all parameters :)
string s ="";
for(int i=0;i< command.Paramerters.Count;i++)
s += command.Parameters[i].ParameterName.tostring()+";";

string testBreakpoint = "sfs";    <--- set breakpoint here.
you should be able to see these parameters

do you use dataset for data?.....

existenz2,
How do I create an insert parameter?

gocemi,
I'm a beginner in ASP.Net, so I don't understand the stuff you have written. Could you please explain more.

I just found out the insert command. Hope this helps.
INSERT INTO [FilesUtilities] ([Uploader], [UploadDate], [FileName], [FileLocation], [Description]) VALUES (@Uploader, @UploadDate, @FileName, @FileLocation, @Description)

Thanks.

 

by: noobe1Posted on 2008-01-15 at 05:35:45ID: 20662366

I got it working!! I should have used @FileName instead of FileName as the parameter.

Protected Sub FileUploadDataSource_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles FileUploadDataSource.Inserting
        e.Command.Parameters("@FileName").Value = "New File"
    End Sub

It seems that you havent defined command parameters.

Add them one by one

Depending of the parameter
if it is odbc

  System.Data.Odbc.OdbcParameter p1 = new System.Data.Odbc.OdbcParameter();
        p1.ParameterName = "Uploader";
        [namespace of your command].Parameters.Add(p1);
System.Data.Odbc.OdbcParameter p2 = new System.Data.Odbc.OdbcParameter();
        p1.ParameterName = "UploadDate";
        [namespace of your command].Parameters.Add(p2);

System.Data.Odbc.OdbcParameter p3 = new System.Data.Odbc.OdbcParameter();
        p1.ParameterName = "FileName";
        [namespace of your command].Parameters.Add(p3);
..
for all of them defined in the command with @ in front.

after you do that you can use them

 

by: gocemiPosted on 2008-01-15 at 05:57:54ID: 20662533

exelent that you've managed it

and it seems that they were defined afterall :)
