我正在尝试使用python函数将某些数据库字段更新为SQLite DB。我不断收到以下错误：

ValueError：操作参数必须为str

下面是我的代码。我很想知道如何在sqlite数据库中更新多个列。

def updateEventData():
    ID = input('Enter ID of row you\'d like to update: ')
    eventname = input('\nPlease enter event name: ')
    startdate = input('\nPlease enter event start date: (DD/MM/YYYY): ')
    enddate = input('\nPlease enter event end date: (DD/MM/YYYY): ')
    venue = input('\nPlease enter event venue: ')

    # Sql update
    sql = """
    UPDATE event_details
    SET name, startdate, enddate, venue, (?, ?, ?, ?)
    WHERE ROWID = ?
    """, (eventname, startdate, enddate, venue, ID)
    c.execute(sql)
    conn.commit()
