Hello John,
I have 2 tables ("pcprod" and "pcdesc"). I´d like to *add *in my application
"MARCA" and "DESCR".
This code is VB2005 .NET. How do I write SQL???
Thanks a lot
Ernany
'***************************************************************
Dim dr As Data.SQLite.SQLiteDataReader
Dim BdMain As New ClsBD
Dim ContLinhas As Integer = 0
Dim indice As Integer = 1
Dim indiceLinha As Integer = 119
BdMain.AbreBD()
dr = BdMain.SQLRetornaDR("SELECT SUM(qtde) AS cont, codigo FROM pcdesc
GROUP BY codigo")
While dr.Read
ContLinhas = ContLinhas + 1
SerialPortLeitura.WriteLine("T 2 0 7 " & indiceLinha & " " &
indice & "- ") 'Indice
SerialPortLeitura.WriteLine("T 2 0 96 " & indiceLinha & " " &
dr("codigo")) 'Codigo
SerialPortLeitura.WriteLine("T 2 0 403 " & indiceLinha & " " &
dr("cont")) 'Quantidade
*add **"MARCA" and "DESCR"* *??????*
dr.Close()
