使用wxPython显示SQL查询结果

Question

我试图从SQL查询中获得结果，以便在脚本执行时显示在文本“Tickets Closed Last 24 Hours”旁边。
SQL查询返回单个数字。 我想获取数字以显示在self.some_text的StaticText框中，它将标签文本更改为运行时的数字。

示例：https://s11.postimg.org/jil0kzfqb/tickets.png 在图像中没有来自SQL查询的编号。 （您可以忽略地址，单元号码和城市的文本和框）

我正在关闭另一个程序别人创建的，因此可能不需要这些代码。 我正在尝试学习SQL和Python，现在几乎是一个新手。

这是我到目前为止的代码：

import wx 
import MySQLdb 

db = MySQLdb.connect(host="xxxxxxxxxxxx",port=xxx,user="xx",passwd="xxxxx",db="xxxx") 

class Data(): 
    def TicketsClosedLast24Hours(self, event): 
     cur = db.cursor() 
     cur.execute("Select COUNT(*) FROM HD_TICKET WHERE HD_STATUS_ID = 12 AND TIME_CLOSED >= NOW() - INTERVAL 1 DAY") 
     row = cur.fetchone() 
     print(row[0]) 
     row = cur.fetchone() 

class MainFrame(wx.Frame): 
    def __init__(self): 
     wx.Frame.__init__(self, None) 

     self.Centre() 
     self.Maximize(True) 

     self.background = wx.Panel(self) 
     self.background.SetBackgroundColour(wx.Colour(98, 125, 152)) 

     self.some_text = wx.StaticText(self.background, wx.ID_ANY, label="", style=wx.ALIGN_CENTER) 
     self.Address = wx.TextCtrl(self.background, -1, "", size=(140, -1)) 
     self.UnitNumber = wx.TextCtrl(self.background, -1, "", size=(140, -1)) 
     self.City = wx.TextCtrl(self.background, -1, "", size=(140, -1)) 

     self.horizontalRow0 = wx.BoxSizer() 
     img1 = wx.Image("logo1.bmp", wx.BITMAP_TYPE_BMP, -1) 
     self.bitmap1 = wx.StaticBitmap(self.background, -1, wx.BitmapFromImage(img1), (55, 0)) 
     self.horizontalRow0.Add(self.bitmap1, wx.Center, border=10) 

     self.VerticalRow1 = wx.BoxSizer(wx.VERTICAL) 
     self.VerticalRow1.Add(wx.StaticText(self.background, -1, "Tickets Closed Last 24 Hours", 
              style=wx.ALIGN_CENTER), flag=wx.ALL, border=5) 
     self.VerticalRow1.Add(wx.StaticText(self.background, -1, "Address:", 
              style=wx.ALIGN_CENTER), flag=wx.ALL, border=9) 
     self.VerticalRow1.Add(wx.StaticText(self.background, -1, "Unit Number:", 
              style=wx.ALIGN_CENTER), flag=wx.ALL, border=9) 
     self.VerticalRow1.Add(wx.StaticText(self.background, -1, "City:", 
              style=wx.ALIGN_CENTER), flag=wx.ALL, border=9) 

     # To add labels - H-1 V-2 
     self.VerticalRow2 = wx.BoxSizer(wx.VERTICAL) 
     self.VerticalRow2.Add(self.some_text, proportion=1, flag=wx.ALL, border=6) 
     self.VerticalRow2.Add(self.Address, proportion=1, flag=wx.ALL, border=6) 
     self.VerticalRow2.Add(self.UnitNumber, proportion=1, flag=wx.ALL, border=6) 
     self.VerticalRow2.Add(self.City, proportion=1, flag=wx.ALL, border=6) 

     # Combine V-1 And V-2 to H1 
     self.horizontalRow1 = wx.BoxSizer() 
     self.horizontalRow1.Add((30, 30), proportion=0, flag=wx.EXPAND, border=0) 
     self.horizontalRow1.Add(self.VerticalRow1, proportion=.5) 
     self.horizontalRow1.Add(self.VerticalRow2, proportion=0) 

     # To add labels - H-3 V-8 
     self.VerticalRow1 = wx.BoxSizer(wx.VERTICAL) 

     # To add labels - H-4 V-9 
     self.horizontalRow4 = wx.BoxSizer() 
     self.horizontalRow4.Add((30, 30), proportion=.5, flag=wx.EXPAND, border=0) 
     self.horizontalRow4.Add((30, 30), proportion=1, flag=wx.EXPAND, border=0) 

     # Adds horizontal Rows to Main Window in Vertical boxes 
     self.verticalBox = wx.BoxSizer(wx.VERTICAL) 
     self.verticalBox.Add(self.horizontalRow0, proportion=0, flag=wx.EXPAND, border=10) 
     self.verticalBox.Add((10, 10), proportion=0, flag=wx.EXPAND, border=10) 
     self.verticalBox.Add(self.horizontalRow1, proportion=0, flag=wx.EXPAND, border=0) 
     self.verticalBox.Add((10, 10), proportion=0, flag=wx.EXPAND, border=10) 
     self.verticalBox.Add(self.horizontalRow4, proportion=0, flag=wx.EXPAND, border=0) 

     self.background.SetSizer(self.verticalBox) 
     self.Show() 

    def someFunction(self): 
     mysql_data = databasemodel.returnData() # query your database to return a string 
     self.some_text.SetLabel(mysql_data) 


if __name__ == '__main__': 
    app = wx.App(redirect=False) 
    window = MainFrame() 
    app.MainLoop() 

任何帮助，将不胜感激。

谢谢！

该代码看起来对我来说是正确的。虽然我没有看到任何实际上叫someFunction的东西。我的猜测是，这是问题。你应该尝试调用它并打印出mysql_data以标准输出，以确保你所接收到的结果是你所期望的。
