count of items or colums of a SQL query using data reader
Greetings,
I need to count the number of colums in a result of a sql query that uses datareader to read the results:
here is the vb code:
Dim conn As New SqlConnection(connectionSt
Dim command As New SqlCommand(strVFD_MO, conn)
command.CommandType = CommandType.Text
conn.Open()
Dim reader As SqlDataReader = command.ExecuteReader()
Dim i As Integer = 0
If reader.HasRows Then
Do While reader.Read()
' the number of colums is unknown, so item id such as reader(0) should not be hard coded
Debug.WriteLine(reader(0),
Loop
End If
thanks!!
