Yii中的数据库事务的使用方法小结
Yii中的数据库事务的使用方法小结
Yii框架是支持数据库事务处理的,关于事务,这里就不多说了,想要了解的读者可以参看本站文章:
关于数据库(MySQL)事务
在项目中遇到批量删除的地方一般会使用到事务,下面列举一个用法实例与大家分享。
<?php $array=array( 0=>array('username'=>'phpernote.com_0','password'=>'123456'), 1=>array('username'=>'u_1','password'=>'123456'), 2=>array('username'=>'u_2','password'=>'123456') ); $transaction=Yii::app()->db->dbConnection->beginTransaction(); //此处db代表的是定义在main.php中的数据库连接对象db try{ Yii::app()->db->createCommand()->insert('tbl_user',$array[0]); Yii::app()->db->createCommand()->insert('tbl_user',$array[1]); Yii::app()->db->createCommand()->insert('tbl_user',$array[2]); $transaction->commit(); }catch(Exception $e){ $transaction->rollback(); }
注意:如果你使用的是MySQL数据库,那么表引擎必须是innodb类型的,因为MySQL数据库的MyISAM引擎不支持事务处理,所以如上代码不会达到预想的目的。

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())

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.

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.

Transactions ensure database data integrity, including atomicity, consistency, isolation, and durability. JDBC uses the Connection interface to provide transaction control (setAutoCommit, commit, rollback). Concurrency control mechanisms coordinate concurrent operations, using locks or optimistic/pessimistic concurrency control to achieve transaction isolation to prevent data inconsistencies.

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.
