Python MySQLdb 批量插入 封裝

def insert_data_many(dbName,list_data_dict): try: # 得到列表的第一個字典集合
        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 "******** 插入失敗 ********"
        print e return 0

 

 

使用說明：

 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 的數據格式是： [{},{},{},{},{},{},{}] 

result1 = insert_data_many(dbName, data_list)
