Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    'MainForm.RootPane.LoadLayout("Layout1") 'Load the layout file.
    MainForm.Show
    TableView1.Initialize("TableView1")
    MainForm.RootPane.AddNode(TableView1, 0, 0, 0, 0)
    MainForm.RootPane.SetAnchors(TableView1, 0, 0,0, 0) 'fill the screen
    reqManager.Initialize(Me, "http://127.0.0.1:17178/rdc")
    GetAnimal("test")
End Sub

Sub GetAnimal(Name As String)
    Dim cmd As DBCommand
    cmd.Initialize
    cmd.Name = "select_animal"
    cmd.Parameters = Array As Object(Name)
    reqManager.ExecuteQuery(cmd, 0, Null)
End Sub

'the server side sql is
sql.select_animal=SELECT name, image, pkey FROM animal where name  ?

sql.select_animal=SELECT name, image, pkey FROM animal where name like ? and pkey=?

GetAnimal("(%, 1)")
