Question

我正在尝试使用python和sqlite从我的数据库中删除用户。

import sqlite3

database_connection = sqlite3.connect('test.db')

delete_username_input = input("Which user you would like to delete?\n\n")
sql = ("DELETE * from USERS where USERNAME = ?")
args = (delete_username_input)
database_connection.execute(sql, args)
database_connection.commit()
database_connection.close()

运行上面的代码时，我收到以下错误：

sqlite3.OperationalError: near "*": syntax error

知道可能导致此错误的原因是什么？

我使用的表格是使用以下语法创建的：

conn.execute('''CREATE TABLE USERS
     (ID INTEGER PRIMARY KEY   AUTOINCREMENT,
     USERNAME       TEXT    NOT NULL,
     PASSWORD       TEXT     NOT NULL,
     WINS           FLOAT   NOT NULL,
     LOSES         FLOAT    NOT NULL,
     GAMESPLAYED   FLOAT NOT NULL,
     WINPERCENT    FLOAT NOT NULL   );''')

任何帮助将不胜感激。

您的SQL语法错误。它应该是

DELETE from USERS where USERNAME = ?

没有*
