修改Oracle密码期限为无限
Oracle提示错误消息ORA-28001: the password has expired,是由于Oracle11G的新特性所致, Oracle 11g创建用户时缺省密码过期限制
Oracle提示错误消息ORA-28001: the password has expired,是由于Oracle11G的新特性所致, Oracle 11g创建用户时缺省密码过期限制是180天(即6个月),, 如果超过180天用户密码未做修改则该用户无法登录。
Oracle公司是为了数据库的安全性默认在11G中引入了这个默认功能,但是这个默认的功能很容易被DBA或者是开发人员给疏忽,一旦密码180天未修改过,就会出现这样的问题。
解决方法:
先使用如下语句查看用户使用的是那个proifle
SELECT username,PROFILE FROM dba_users;
可通过如下SQL语句 查询密码的有效期设置,LIMIT字段是密码有效天数。
SELECT * FROM dba_profiles WHERE profile='DEFAULT' AND resource_name='PASSWORD_LIFE_TIME' ;
在密码将要过期或已经过期时可通过如下语句进行修改密码,密码修改后该用户可正常连接数据库。
ALTER USER 用户名 IDENTIFIED BY 密码
如果想去除180天的密码生存周期的限制可通过如下SQL语句将其关闭 ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;
如上SQL语句将口令有效期默认值180天修改成了“无限制”。但是出于数据库安全性考虑,不建议将PASSWORD_LIFE_TIME值设置成UNLIMITED,建议大家定期修改数据库用户口令。

Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.

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.
