am使用treeview创建了一个表,我希望在从mysql table.if获取的数据中插入--任何人都可以帮助我,因为我已经尽了最大的努力,但仍然在vain.with中-- tree.insert("", 1, text=2, values=("name", "5", "5"))可以插入很好的数据,但不能从数据库中插入,但是我想从数据库中获取并显示它。这是我尝试过的代码,但是它有failed.please帮助。`
from Tkinter import *
import ttk
import MySQLdb
root = Tk()
root.geometry("320x240")
tree = ttk.Treeview(root)
conn = MySQLdb.connect("localhost", "root", "drake", "OSCAR")
cursor = conn.cursor()
tree["columns"] = ("one", "two", "three")
tree.column("one", width=100)
tree.column("two", width=100)
tree.column("three", width=100)
tree.heading("#0", text='ID', anchor='w')
tree.column("#0", anchor="w")
tree.heading("one", text="NAME")
tree.heading("two", text="VOTES")
tree.heading("three", text="PERSENTAGE")
for i in range(1, 6):
cursor.execute("""select name from president where ID =%s""", (i,))
nm = cursor.fetchone()[0]
cursor.execute("""select votes from president where ID =%s""", (i,))
vot = cursor.fetchone()[0]
cursor.execute("""select percentage from president where ID =%s""",(i,))
percent = cursor.fetchone()[0]
tree.insert("", i, text=i, values=(nm, vot, percent)),
tree.pack()
root.mainloop()`

要解决问题,首先需要使用以下查询读取数据库的所有行:
SELECT * FROM president您需要执行以下操作:
cursor.execute("""SELECT * FROM president""")现在,简单地遍历行并在tree中逐个插入它们。
更新:
我想你的桌子结构是这样的:
ID | name | votes | percentage所以你可以运行这个:
cpt = 0 # Counter representing the ID of your code.
for row in cursor:
# I suppose the first column of your table is ID
tree.insert('', 'end', text=str(cpt), values=(row[1], row[2], row[3]))
cpt += 1 # increment the IDhttps://stackoverflow.com/questions/36384692
