Question

In my VB.net code i have:

    cmd.CommandText = "SELECT * FROM [strfg].[dbo].[Myfunc] (@MyParam)"
    Dim myparam As New SqlParameter("@MyParam", a)
    cmd.Parameters.Add(myparam)

The function (runnig on SQL server) returns a table with four columns, one row.

How do I call this function from Visual Basic? cmd.ExecuteScalar() is obviously not correct. In c++ I use a recordset. What is the equivalent in vb? Does anyone have a short example?

Answer 1

You want to do something like this:

Dim reader As SqlDataReader= cmd.ExecuteReader
Dim MyList as new List(Of WhateverObject)
Do While reader.Read
    Dim obj as new WhateverObj
    obj.Property1 = Reader.GetInt32(0)
    obj.Property2 = Reader.GetString(1)
    MyList.add(obj)
Loop

reader.Close()
cmd.Dispose()

Where you use the index value based on the order of the returned fields, and its type in the Get.
