确定是否有新部署（数据库存在）

Question

我使用SSDT进行数据库部署。我从部署后脚本中添加了静态数据。虽然有很多数据，但如果没有必要，我也不希望这样做。

基本上我需要的是：

class RegisterNewAppointmentFrameStep2( wx.Frame ):
    def __init__( self, parent, firstName ):
    global cursor
    wx.Frame.__init__( self, parent = parent , id = -1, title = u'Marcação de consulta', size = ( 271, 138 ),
        style = wx.DEFAULT_FRAME_STYLE ^ ( wx.RESIZE_BORDER | wx.MINIMIZE_BOX | wx.MAXIMIZE_BOX ) )
    #Centers this RegisterNewAppointmentFrameStep2:
    self.Center()
    #Creates panel as a child of this RegisterNewAppointmentFrameStep2:
    self.panel = wx.Panel( parent = self )
    #Query to determine all patients with the first name provided:
    results = cursor.execute( 'SELECT * FROM Paciente WHERE Primeiro_Nome = ( ? )', ( firstName, ) )
    results = results.fetchall()
    size = len( results )
    if size > 1: #size >= 2.
        self.instructionsLabel = wx.StaticText( self.panel, -1, '%d pacientes encontrados. Por favor selecione\nabaixo o sobrenome do paciente desejado.' % size,
            pos = ( 10, 10 ), size = ( 700, 200 ) )
        self.firstNameLabel = wx.StaticText( self.panel, -1, firstName, pos = ( 10, 50 ) )
        comboBoxValues = []
        for result in results:
            comboBoxValues.append( result[ 2 ] )
        self.dropDownList = wx.ComboBox( parent = self, id = -1, pos = ( 70, 50 ), size = ( 163, -1 ), choices = comboBoxValues, style = wx.CB_READONLY | wx.CB_SORT )
        boxSizer = wx.BoxSizer( wx.HORIZONTAL )
        boxSizer.Add( self.instructionsLabel, 1, wx.EXPAND )
        boxSizer.Add( self.firstNameLabel, 1, wx.EXPAND )
        boxSizer.Add( self.dropDownList, 1, wx.EXPAND )

最好的方法是什么？
