sqlite3.OperationalError：没有这样的列：uid

Question

我使用此代码在python中创建了一个sqlite表

db.execute('CREATE TABLE const (uid INT UNIQUE ,article INT, sub INT, content TEXT)')

我尝试使用此代码在表上执行select-where状态

cursor = db.execute('SELECT sub FROM const WHERE uid = ?', uid)

我得到的就是这个错误：

sqlite3.OperationalError: no such column: uid

我试过搜索，但对于像我这样的新手似乎没有明确的解释和解决这个错误。请帮忙

这里是我的代码

#!/usr/lib/python3m

import sqlite3


article = 0
sub = 0
text = ''
count = 0
flag = False
close_tag = False


def close():
    global text
    global close_tag

    if close_tag:
        a = 0
        while a < count:
            a += 1
            text += '</ol>'
    close_tag = False


def get():
    close()
    # out = open('output.txt', 'a')
    # print('Article: ' + str(article), end='', file=out)
    # print('\n' + 'Sub: ' + str(sub) + '\n', end='', file=out)
    # print(text + '\n', file=out, end='')

    # print('Article: ' + str(article), end='')
    # print('\n' + 'Sub: ' + str(sub) + '\n', end='')
    # print(text + '\n', end='')


    db = sqlite3.connect('const_enGB')
    # if not (article == a and sub == s):
    uid = int(str(article) + str(sub))
    cursor = db.execute('SELECT sub FROM const WHERE uid = ?', uid)
    if not cursor:
        db.execute('INSERT INTO const (uid, article, sub, content) VALUES (?,?,?,?)', uid, article, sub, text))
    else:
        db.execute('UPDATE const SET article = ?, sub =?, content=? WHERE uid = ? ',     (article, sub, text))
    db.commit()
