Python将JSON格式数据转换为SQL语句以便导入MySQL数据库_MySQL
JSONpython
前文中我们把网络爬虫爬取的数据保存为JSON格式,但为了能够更方便地处理数据,我们希望把这些数据导入到MySQL数据库中。phpMyadmin可以把MySQL数据库中的数据导出为JSON格式文件,但却不能把JSON格式文件导入到MySQL数据库。为了实现这个目标,可以编写Python脚本将JSON格式数据转换为SQL语句以便导入MySQL数据库。
JSON文件tencent.json部分内容:
{"recruitNumber": "1", "name": "SD10-FPS俄语游戏海外PM(深圳)", "detailLink": "http://hr.tencent.com/position_detail.php?id=9587&keywords=&tid=0&lid=0", "publishTime": "2013-11-13", "catalog": "产品/项目类", "workLocation": "深圳"}
{"recruitNumber": "2", "name": "HY2-互动娱乐游戏网游财产安全运营专员(深圳)", "detailLink": "http://hr.tencent.com/position_detail.php?id=9482&keywords=&tid=0&lid=0", "publishTime": "2013-11-28", "catalog": "产品/项目类", "workLocation": "深圳"}
在phpMyadmin中创建数据库及表结构:
CREATE DATABASE itzhaopin;
CREATE TABLE IF NOT EXISTS `tencent` (`id` int(11) NOT NULL auto_increment,`name` varchar(512)default NULL,`catalog` varchar(64) default NULL,`workLocation` varchar(64) default NULL,`recruitNumber` varchar(64) default NULL,`detailLink` varchar(1024) default NULL,`publishTime` varchar(64) default NULL,PRIMARY KEY (`ID`)) ENGINE=MyISAMDEFAULT CHARSET=utf8 AUTO_INCREMENT=1;
#-*- coding: UTF-8 -*-import jsondata = []with open('itzhaopin/tencent.json') as f: for line in f: data.append(json.loads(line))#print json.dumps(data, ensure_ascii=False)str = "/r/n"for item in data: #print json.dumps(item) str = str + "insert into tencent(name,catalog,workLocation,recruitNumber,detailLink,publishTime) values " str = str + "('%s','%s','%s','%s','%s','%s');/r/n" % (item['name'],item['catalog'],item['workLocation'],item['recruitNumber'],item['detailLink'],item['publishTime'])import codecsfile_object = codecs.open('tencent.sql', 'w' ,"utf-8")file_object.write(str)file_object.close()print "success"
执行该python脚本,在当前目录下将生成一个名为tencent.sql的文件,在phpMyadmin中导入并执行该文件,爬虫抓取的数据将导入MySQL数据库。

1. Check the wifi password: Make sure the wifi password you entered is correct and pay attention to case sensitivity. 2. Confirm whether the wifi is working properly: Check whether the wifi router is running normally. You can connect other devices to the same router to determine whether the problem lies with the device. 3. Restart the device and router: Sometimes, there is a malfunction or network problem with the device or router, and restarting the device and router may solve the problem. 4. Check the device settings: Make sure the wireless function of the device is turned on and the wifi function is not disabled.

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

To handle database connection errors in PHP, you can use the following steps: Use mysqli_connect_errno() to obtain the error code. Use mysqli_connect_error() to get the error message. By capturing and logging these error messages, database connection issues can be easily identified and resolved, ensuring the smooth running of your application.

HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.

Through the Go standard library database/sql package, you can connect to remote databases such as MySQL, PostgreSQL or SQLite: create a connection string containing database connection information. Use the sql.Open() function to open a database connection. Perform database operations such as SQL queries and insert operations. Use defer to close the database connection to release resources.

Using the database callback function in Golang can achieve: executing custom code after the specified database operation is completed. Add custom behavior through separate functions without writing additional code. Callback functions are available for insert, update, delete, and query operations. You must use the sql.Exec, sql.QueryRow, or sql.Query function to use the callback function.
