'builtin_function_or_method'对象的cursor.ececute（statement）没有属性'execute' [英] 'builtin_function_or_method' object has no attribute 'execute' for cursor.ececute(statement)

问题描述

c = sqlite3.connect(history_db)
cursor = c.cursor

select_statement = "SELECT urls.urls,urls.Visit_count FROM urls,Visits WHERE 
urls.id=visits.urls;"
cursor.execute(select_statement)

results = c.cursor.fetchcall()

print(results)

上面的代码在执行时会给出类似错误

The code above when executed gives an error something like

Traceback (most recent call last):
File "test.py", line 13, in <module>
cursor.execute(select_statement)
AttributeError: 'builtin_function_or_method' object has no attribute 
'execute'

我是不熟悉python sqlite3的人，那么如何在python中使用sqlite3执行此查询？

I am new to using python sqlite3 so how do I execute this query with sqlite3 in python?

推荐答案

Connection.cursor 是一个方法，如果不调用它，则得到方法对象本身，而不是调用它的结果。 IOW，您想要的是

Connection.cursor is a method, if you don't call it you get the method object itself, not the result of calling it. IOW, what you want is

cursor = c.cursor()
