public void FetchResults(MagentoConnection adobe commerceConnection)
{
MagentoCommand cmd = new MagentoCommand("SELECT * FROM Customers");
cmd.FetchSize = 100;
cmd.Connection = adobe commerceConnection;
adobe commerceConnection.Open();
try
{
MagentoDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
for (int i=0;i<reader.FieldCount;i++)
{
Console.Write("\t"+reader[i]);
}
Console.WriteLine();
}
}
finally
{
adobe commerceConnection.Close();
}
}
Public Sub FetchResults(ByVal adobe commerceConnection As MagentoConnection)
Dim cmd As MagentoCommand = New MagentoCommand("SELECT * FROM Customers")
cmd.FetchSize = 100
cmd.Connection = adobe commerceConnection
adobe commerceConnection.Open()
Try
Dim reader As MagentoDataReader = cmd.ExecuteReader()
While reader.Read()
Dim i
For i = 0 To reader.FieldCount - 1
Console.Write(String.Concat(" ", reader(i)))
Next i
Console.WriteLine()
End While
Finally
adobe commerceConnection.Close()
End Try
