ich weiß nicht, ob MySQL integrierte Sicherheit akzeptiert.

i diesen auf mysql verwenden, geben Sie str_query es Datentabelle Ergebnis liefert

Public Function mysql(ByVal str_query As String) As DataTable 
     Dim adptr As New MySqlDataAdapter 
     Dim filltab As New DataTable 
     Try 
      Using cnn As New MySqlConnection("server=" & mysql_server & ";user=" & mysql_user & ";password=" & mysql_password & ";database=" & mysql_database & ";Allow User Variables=True") 
       Using cmd As New MySqlCommand(str_query, cnn) 
        cnn.Open() 
            adptr = New MySqlDataAdapter(cmd) 
        adptr.Fill(filltab) 
        cnn.Close() 
       End Using 
      End Using 
     Catch ex As Exception 
'you can log mysql errors into a file here log(ex.ToString) 
     End Try 
     Return filltab 
    End Function
