Hi Everyone,

I currently have a webform as a front end to capture and insert data into an MS SQL database.  I would like to execute a SQL function within my code but have no idea how to go about doing this.  the function's name is 'GetChannel' and it decodes the PBR's ID accordingly to get the right channel.  I've attached my current VB.NET code to insert data into the database.  Would someone be able to help me to call the sql function from my current code?

 
'Open connection string and insert data into the ST database
        
Dim ConnectionString As String
        Dim Connection As SqlConnection
        Dim Adapter As New SqlDataAdapter
        Dim sql As String



        ConnectionString = "Data Source=00.0.000.00;Initial Catalog=ST;User ID=user;pwd=pwd;"
        Connection = New SqlConnection(ConnectionString)

  sql = "insert into table (PBR_ID, Others_Details, Contact_Flag, Comments) VALUES (@PBRID, @Others, '" & ddlcontact.SelectedValue & "', @Comments);"

            Try
                Connection.Open()


                Adapter.InsertCommand = New SqlCommand(sql, Connection)

                Adapter.InsertCommand.Parameters.AddWithValue("@PBRID", tbpbrid.Text)
   Adapter.InsertCommand.Parameters.AddWithValue("@Others", tbneedsothers.Text)
                Adapter.InsertCommand.Parameters.AddWithValue("@Comments", tbcomments.Text)

Adapter.InsertCommand.ExecuteNonQuery()

                Response.Write("<span style='color: green'>Data Submitted</span>")

            Catch ex As Exception
                Response.Write("<span style='color: red>Data Not Submitted</span>")
            End Try

Hi

try following code on line no 13

sql =  "insert into table (PBR_ID, Others_Details, Contact_Flag, Comments) VALUES (dbo.GetChannel(ARGUMENTS), @Others, '" & ddlcontact.SelectedValue & "', @Comments);"

replace dbo with your original schema and
ARUGMENTS with your real arguments

Thanks Deepaklakkad - i tried what you suggested but it's not inserting.  I am actually trying to insert the results from GetChannel Function into another field within the table.  I've included the changes... Not sure what i'm doing wrong...

'Open connection string and insert data into the service_Tracking database, ABM Coupon Data table
        Dim ConnectionString As String
        Dim Connection As SqlConnection
        Dim Adapter As New SqlDataAdapter
        Dim sql As String



        ConnectionString = "Data Source=00.0.000.00;Initial Catalog=ST;User ID=user;pwd=pwd;"
        Connection = New SqlConnection(ConnectionString)

       

            sql = "insert into Table(PBR_ID, Others_Details, Contact_Flag, Comments, Channel) VALUES (@PBRID, @Others, '" & ddlcontact.SelectedValue & "', @Comments, dbo.GetChannel(PBR_ID));"

            Try
                Connection.Open()


                Adapter.InsertCommand = New SqlCommand(sql, Connection)

                Adapter.InsertCommand.Parameters.AddWithValue("@PBRID", tbpbrid.Text)
                Adapter.InsertCommand.Parameters.AddWithValue("@Others", tbneedsothers.Text)
                Adapter.InsertCommand.Parameters.AddWithValue("@Comments", tbcomments.Text)

                Adapter.InsertCommand.ExecuteNonQuery()

                Response.Write("<span style='color: green'>Data Submitted</span>")

            Catch ex As Exception
                Response.Write("<span style='color: red>Data Not Submitted</span>")
            End Try

I tried the above code and it's not working...

The SQL function is actually stored in the MSSQL database as oppose to a code on my side - does that make a difference?
