MSSQL Server2000数据库分离与附加

如果您数据库系统安装在系统盘(比如C盘)，由于C盘容易受病毒侵害，您也许希望您的数据存放在非系统盘(比如D盘)，要做的这点很简单，您并不需要重装数据库，只要把数据“分离”，然后将相关文件复制到D盘的某个目录，接着“附加”数据库即可。
SQL Server 2000允许分离数据库的数据和事务日志文件，然后将其重新附加到同一台或另一台服务器上。分离数据库将从SQL Server 删除数据库，但是保持在组成该数据库的数据和事务日志文件中的数据库完好无损。然后这些数据和事务日志文件可以用来将数据库附加到任何SQL Server实例上，这使数据库的使用状态与它分离时的状态完全相同。
数据库分离和附加其实很简单，您即使是初次接触数据库，，做起来也很容易。
一、分离数据库
1、点击“程序》Microsoft SQL Server》企业管理》”，打开企业管理器
2、展开服务器组，然后展开服务器，选中要分离的数据库
3、点击鼠标右键“所有任务》分离数据库”，出现如下窗口
4、点击确定，该选定的数据库就被分离。
应注意，只有“使用本数据库的连接”数为0时，该数据库才能分离。所以分离数据库时尽量断开所有对要分离数据库操作的连接，如果还有连接数据库的程序，会出现数据库的连接状态窗口，显示正在连接此数据库的机器以及名称，点击清除按钮将从服务器强制断开现有的连接。
二、附加数据库
1、复制移动数据库文件
在附加数据库之前，您必须将与数据库关联的 .MDF(主数据文件).LDF(事务日志文件)这两个文件复制到目标服务器上，或是同一服务器的不同文件目录下。这两个文件一般位于C：Program FilesMicrosoft SQL ServerMSSQLData目录下。
2、点击“程序》Microsoft SQL Server》企业管理》”，打开企业管理器
3、展开服务器组，然后展开服务器
4、右击"数据库"，然后选择“所有任务》附加数据库”，弹出窗口
5、输入要附加的数据库的MDF名称。如果不确定文件位于何处，单击浏览("...")搜索。若要确保指定的 MDF 文件正确，请单击"验证"。在"附加为"框内，输入数据库的名称。数据库名称不能与任何现有数据库名称相同。指定数据库的所有者
6、单击"确定"按钮。新附加的数据库的数据库节点即创建在"数据库"文件夹中。

How does Go language implement the addition, deletion, modification and query operations of the database?
Mar 27, 2024 pm 09:39 PM
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.

How does Hibernate implement polymorphic mapping?
Apr 17, 2024 pm 12:09 PM
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.
iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos
Jul 18, 2024 am 05:48 AM
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
An in-depth analysis of how HTML reads the database
Apr 09, 2024 pm 12:36 PM
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.
