Question

我有几个查询。我的大多数插入查询都有效，并且它们遵循与该插入查询相同的格式（我什至可以复制粘贴并根据需要进行修改）。由于某种原因，此查询使我陷入语法错误，但我不确定为什么。

我已经查看了SO上用于解决此错误的各种解决方案。似乎人们是出于各种不同的原因而获得它的，而我不确定到底是什么原因导致了此错误。我看不到该语句有问题。

def set_prices(game_name, vendor_id, vendor_name, game_id, game_platform, vendor_store_link, current_price_at_vendor, previous_price_at_vendor, historical_low_at_vendor):
    # Create the query
    insert_price_data = """ INSERT INTO game_vendors
            (game_name, vendor_id, vendor_name, game_id, game_platform, vendor_store_link, current_price_at_vendor, previous_price_at_vendor, historical_low_at_vendor, historical_low_date)
            VALUES (%s,%s,%s,%s,%s,%s,%s,%s,%s,%s); """

    vals = (game_name, vendor_id, vendor_name, game_id, game_platform, vendor_store_link, current_price_at_vendor, previous_price_at_vendor, historical_low_at_vendor, datetime.datetime.now().strftime("%Y/%m/%d").replace('/', '-'))

    send_to_db(insert_price_data, vals)

set_prices("borderlands 3", "1", "xbox", "26", "xbox one", "xbox.com", "45", "45", "25")

我没想到会收到此错误，因为以前的任何SQL语句都没有发生此错误。

“ 1064（42000）：您的SQL语法有错误；请查看手册对应于您的MySQL服务器版本的正确语法，在第4行的'％s，％s，％s，％s，％s，％s，％s，％s，％s，％s）'附近使用

我敢打赌，这是我忽略的小事。

更新send_to_db()函数：

def send_to_db(query,  multi_result=False, vals=None):
    # this function opens a database query for a connection
    # build engine for database
    db_engine = mysql.connector.connect(
        host="localhost",
        user="root",
        passwd="",
        database="mydb",
    )

    # Initiate the cursor
    cursor = db_engine.cursor()
    # row = None
    # rows = None

    try:
        if vals:
            # insert queries require vals
            cursor.execute(query, vals)
            db_engine.commit()

        else:
            # select queries which don't require vals
            cursor.execute(query)
            if multi_result:
                rows = cursor.fetchall()
                return rows
            else:
                row = cursor.fetchone()
                return row

    except mysql.connector.Error as error:
        print(error)

    finally:
        if db_engine.is_connected():
            cursor.close()
            db_engine.close()
            print("MySQL connection is closed")
            db_engine.disconnect()

使用mysql.connector for Python的（％s％s％s）附近的语法错误
