Python MySQLdb 批量插入 封装

def insert_data_many(dbName,list_data_dict):
    try:
        # 得到列表的第一个字典集合
        data_dict = list_data_dict[0]
        # 得到（s%，s%，s%，s%）
        data_values = "(" + "%s," * (len(data_dict)) + ")"
        data_values = data_values.replace(',)', ')')

        dbField = data_dict.keys()
        dataTuple = tuple(data_dict.values())
        dbField = str(tuple(dbField)).replace("'",'')
        conn = MySQLdb.connect(host="xxxxxxx", user="xxxx", passwd="xxxxxx", db="xxxxxx", charset="utf8")
        cursor = conn.cursor()

        sql = """ insert into %s %s values %s """ % (dbName,dbField,data_values)

        params = []
        for item in list_data_dict:
            params.append(tuple(item.values()))
        params = tuple(params)

        cursor.executemany(sql, params)
        conn.commit()
        cursor.close()

        print "=====  插入成功  ====="
        return 1

    except Exception as e:
        print "********     插入失败   ********"
        print e
        return 0

 

 

使用说明：

 data2 = {

                "sold_price":str(sold_price),
                "estimate_price":str(estimate_price),
                "item_url":str(item_url),
                "item_imgurl":str(item_imgurl),
                "item_lotnum":str(item_lotnum),

                "hashcode": hashcode,
                "create_time": create_time,
            }



data_list.append(data_dict)

dbName = "oversea_thierrydemaigret_2017_2_no_detail_info"

# 其中 data_list 的数据格式是： [{},{},{},{},{},{},{}] 

result1 = insert_data_many(dbName, data_list)
