数据库检测工具
每隔一段时间查询一次数据库信息并返回listbox中进行展示```
import tkinter as tk
from tkinter import ttk, messagebox, simpledialog
import os
import cx_Oracle
import time
import threading
class MemoApp(tk.Tk):
def __init__(self):
super().__init__()
self.title("数据库监控工具")
self.geometry("400x300")
self.resizable(False, False)
#self.attributes("-alpha", 0.7)
# 创建笔记本卡片
self.notebook = ttk.Notebook(self)
self.notebook.pack(expand=True, fill="both")
# 创建查询卡片
self.cx1 = tk.Frame(self.notebook)
self.notebook.add(self.cx1, text="数据库查询")
self.cx1_list = tk.Listbox(self.cx1)
self.cx1_list.pack(expand=True, fill="both")

self.thread = threading.Thread(target=self.Oracle_link())
self.thread.start()
def Oracle_link(self):
conn = cx_Oracle.connect('')# 这里的顺序是用户名/密码@oracleserver的ip地址/数据库名字
cursor = conn.cursor()
print('连接数据库成功！')
self.cx1_list.delete(0, tk.END)
self.cx2_list.delete(0, tk.END)

sql1 = "select ywh from testtable1"

#print(all.fetchall())

# 主程序入口
if __name__ == "__main__":
app = MemoApp()
app.mainloop()
```
效果图如下： 学习一下 学习一下 学习一下 学习下，探讨下 学习一下~ 这个还真是蛮有启发的 检测思路值得学习，感谢分享！ 感谢分享！ 感谢分享！
