重命名SQLServer数据库的方法
本文讲解重命名SQLServer 数据库，包括物理文件名、逻辑文件名的改名
企业管理器中没有改数据库名的功能，如果一定要用企业管理器来实现，你可以备份数据库，然后还原，在还原时候可以指定另一个库名，然后再删除旧库就行了。这里以 SQLServer 20000 为例，旧数据库名字为 Admin10000， 新数据库名字为 jb51.net。
第一步、备份数据库
打开企业管理器
-- 右键一个数据库
-- 所有任务
-- 备份数据库
-- 目的--备份到中选择添加
-- 输入一个备份的文件名(注意,如果原来有文件名,要删除它)
-- 确定
第二步、还原数据库，并指定一个新库名，并且修改物理文件名。
企业管理器--右键 "数据库 "--所有任务--还原数据库
-- "还原为数据库库" 中输入还原后的数据库名 jb51.net
-- 还原选择 "从设备 "--选择设备--添加--添加你的备份文件--确定，回到数据库还原的界面
-- 备份号--选择内容--选择你要恢复那次备份的内容
-- 选项--将 "移至物理文件名 "中的物理文件名修改为你的数据文件要存放的文件名，这里修改为 jb51.net_Data.MDF(数据库文件) 和 jb51.net_Log.LDF(日志文件)
-- 如果要还原的数据库已经存在,选择 "在现有数据库上强制还原 "
-- 确定
第三步、修改逻辑文件名
如果想修改逻辑文件名，可以查询分析器里输入
alter database [jb51.net]
modify file ( name='Admin10000_Data', newname='jb51.net_Data')
alter database [jb51.net]
modify file ( name='Admin10000_log', newname='jb51.net_log')
第四步、最后删除旧的数据库 jb51

What is the difference between mysql and sqlserver syntax
Apr 22, 2024 pm 06:33 PM
The syntax differences between MySQL and SQL Server are mainly reflected in database objects, data types, SQL statements and other aspects. Database object differences include the storage engine and how filegroups are specified, and the creation of indexes and constraints. Data type differences involve differences in numeric types, character types, and date and time types. SQL statement differences are reflected in result set limitations, data insertion, update and delete operations, etc. Other differences include how identity columns, views, and stored procedures are created. Understanding these differences is important to avoid errors when using different database systems.
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.

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.

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.
