插入查询提供不受支持的类型错误

def insert_history(self, time, date, url):

    db = sqlite3.connect('/home/amol/BE_project/Browser.db')
    cursor = db.cursor()
    params = (url, time, date)
    cursor.execute("INSERT INTO history(url, time, DATE) values(?, ?, ?)",params)
    db.commit()

出现以下错误:

cursor.execute(“INSERT INTO history(url,time,DATE)values(?,?,?)”,params)sqlite3.InterfaceError:绑定参数1时出错 - 可能是不支持的类型 .

架构是:

sqlite> .schema history
CREATE TABLE history(id INTEGER PRIMARY KEY AUTOINCREMENT, url TEXT , time text, DATE text );

提前致谢
