Python/MySQL：表没有得到更新

Question

我正在从一个学校项目工作，从Excel表单中提取数据并将数据放入数据库中。在运行下面的代码并运行SQL命令SELECT * FROM items后，它将返回“空集”。我究竟做错了什么？我在这里先向您的帮助表示感谢！

import openpyxl 
import MySQLdb as mdb 

db = mdb.connect('localhost', 'root', 'TRM4611', 'practice') 
cur = db.cursor() 

wb_choice = input('What workbook would you like to use?\n--> ') 

wb = openpyxl.load_workbook(wb_choice + '.xlsx') 

all_sheets = wb.get_sheet_names() 

with db: 
    for sheet in all_sheets: 
     current_sheet = wb.get_sheet_by_name(sheet) 
     print ('\nCurrent Sheet: ' + current_sheet.title) 
     for i in range(current_sheet.max_column): 
      for cellObj in current_sheet.columns[i]: 
       if i == 0: 
        cur.execute("INSERT INTO items(Date) VALUES(%s)", (cellObj.value,)) 
       if i == 1: 
        cur.execute("INSERT INTO items(Fruit) VALUES(%s)", (cellObj.value,)) 
       if i == 2: 
        cur.execute("INSERT INTO items(Quantity) VALUES(%s)", (cellObj.value,)) 

       print (cellObj.coordinate, cellObj.value) 
      print ('--- END OF ROW ---')

你缺少的承诺，您必须在INSERT的

db.commit()
