本文章介绍了关于SQL2005附加数据库出错(错误号:5123) 的方法,有需要了解的同学可参考一下下。
错误提示】
无法为此请求检索数据。(Microsoft.SqlServer.SmoEnum)其他信息执行Transact-Sql语句或批处理时发生了异常。(Microsoft.SqlServer.ConnectionInfo)尝试打开或创建物理文件“d:Data***.mdf”时,Create file遇到操作系统错误5(拒绝访问。)
【问题背景】
版本:SQL Server 2005企业版
操作系统版本:Windows Server 2003企业版
错误引发描述:数据库分离后,把数据硬盘从一台主机换挂到另一台主机上(两台主机的操作系统和数据库版本都是一样的)。结果附加数据库时,提示上面的错误。
【问题分析】
很明显,是文件操作权限不够引发的问题。
【解决方法】
给数据库文件所在的文件夹属性安全里添加相应的用户并赋予完全操作权限即可解决问题(网上的资料都是这么说的)。给什么用户添加权限呢?比如:Administrators用户组、NETWORK SERVICE、MSSQLUser或Everyone,具体用哪个,看你的SQL服务是哪个帐户启动的,如果不清楚或者懒一点,可以直接添加Everyone用户。本来想上个截图的,不知道为什么,几十Kb的图片,一直上传不成功。
【意外情况】
可能你通过上面的解决方法,给数据文件所在的文件夹添加了相应的用户和操作权限,但问题依旧(这也正是我纠结痛苦的地方,网上都是那么说的,咋就不行哩~~??!)。最后我的解决方法是:给每个数据库文件(包括mdf、ldf、ndf)分别设置用户和操作权限(操作方法和给文件夹加操作权限一样,都是在右键属性里的安全选项)。问题终于彻底得到解决。原因应该是文件夹的权限没有自动继承到里面的文件上。

MySQL uses a GPL license. 1) The GPL license allows the free use, modification and distribution of MySQL, but the modified distribution must comply with GPL. 2) Commercial licenses can avoid public modifications and are suitable for commercial applications that require confidentiality.

The situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.

There are four main index types in MySQL: B-Tree index, hash index, full-text index and spatial index. 1.B-Tree index is suitable for range query, sorting and grouping, and is suitable for creation on the name column of the employees table. 2. Hash index is suitable for equivalent queries and is suitable for creation on the id column of the hash_table table of the MEMORY storage engine. 3. Full text index is used for text search, suitable for creation on the content column of the articles table. 4. Spatial index is used for geospatial query, suitable for creation on geom columns of locations table.

The main difference between MySQL and SQLite is the design concept and usage scenarios: 1. MySQL is suitable for large applications and enterprise-level solutions, supporting high performance and high concurrency; 2. SQLite is suitable for mobile applications and desktop software, lightweight and easy to embed.

Indexes in MySQL are an ordered structure of one or more columns in a database table, used to speed up data retrieval. 1) Indexes improve query speed by reducing the amount of scanned data. 2) B-Tree index uses a balanced tree structure, which is suitable for range query and sorting. 3) Use CREATEINDEX statements to create indexes, such as CREATEINDEXidx_customer_idONorders(customer_id). 4) Composite indexes can optimize multi-column queries, such as CREATEINDEXidx_customer_orderONorders(customer_id,order_date). 5) Use EXPLAIN to analyze query plans and avoid

Using transactions in MySQL ensures data consistency. 1) Start the transaction through STARTTRANSACTION, and then execute SQL operations and submit it with COMMIT or ROLLBACK. 2) Use SAVEPOINT to set a save point to allow partial rollback. 3) Performance optimization suggestions include shortening transaction time, avoiding large-scale queries and using isolation levels reasonably.
