HomeDatabaseMysql Tutorial无法用排他锁锁定该数据库

今天实现SQL视频中的例子时,为了避免建立过多的数据库,就想着将已经使用了的数据库名称改成需要的,但是电脑很调皮总是告诉我: 出现这种错误以后,摆在我面前的有两条路:一,我上网查出解决方案,解决后再往下进行(也许时间会久于新建数据库的时间);

   今天实现SQL视频中的例子时,为了避免建立过多的数据库,就想着将已经使用了的数据库名称改成需要的,但是电脑很调皮总是告诉我:

     无法用排他锁锁定该数据库

          出现这种错误以后,摆在我面前的有两条路:一,我上网查出解决方案,解决后再往下进行(也许时间会久于新建数据库的时间);二,先不管它,新建一个数据库先用着。现在是需要建立的数据库不多,如果多了就成了0.99和1.01的定律,最终的损失将不可估量。

          现整理出以下的解决方案(以SQl Server 2008为例):

          1.打开SQL management studio ,右击需要命名的数据库,选择属性,点击属性中的“选项”,如下图:

              

           无法用排他锁锁定该数据库

2.选定选项之后,右下方滚动条中有“状态”一栏,将“状态”下的“限制访问”更改为“SINGLE_USER”,如图所示:

       无法用排他锁锁定该数据库

3.点击确定,保存以上的修改。保存以后会发现,经过修改的数据库名称和其他的区别:

    无法用排他锁锁定该数据库

  这就标识着修改成功,可以进行重命名的操作了。如果上述修改已经完成但不能重命名,则需重启一下SQl Server Management Studio。

What are some common security vulnerabilities in MySQL?What are some common security vulnerabilities in MySQL?Apr 26, 2025 am 12:27 AM

Common security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.

How can you identify slow queries in MySQL?How can you identify slow queries in MySQL?Apr 26, 2025 am 12:15 AM

Identifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.

How can you monitor MySQL server health and performance?How can you monitor MySQL server health and performance?Apr 26, 2025 am 12:15 AM

To monitor the health and performance of MySQL servers, you should pay attention to system health, performance metrics and query execution. 1) Monitor system health: Use top, htop or SHOWGLOBALSTATUS commands to view CPU, memory, disk I/O and network activities. 2) Track performance indicators: monitor key indicators such as query number per second, average query time and cache hit rate. 3) Ensure query execution optimization: Enable slow query logs, record and optimize queries whose execution time exceeds the set threshold.

Compare and contrast MySQL and MariaDB.Compare and contrast MySQL and MariaDB.Apr 26, 2025 am 12:08 AM

The main difference between MySQL and MariaDB is performance, functionality and license: 1. MySQL is developed by Oracle, and MariaDB is its fork. 2. MariaDB may perform better in high load environments. 3.MariaDB provides more storage engines and functions. 4.MySQL adopts a dual license, and MariaDB is completely open source. The existing infrastructure, performance requirements, functional requirements and license costs should be taken into account when choosing.

How does MySQL's licensing compare to other database systems?How does MySQL's licensing compare to other database systems?Apr 25, 2025 am 12:26 AM

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.

When would you choose InnoDB over MyISAM, and vice versa?When would you choose InnoDB over MyISAM, and vice versa?Apr 25, 2025 am 12:22 AM

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.

Explain the purpose of foreign keys in MySQL.Explain the purpose of foreign keys in MySQL.Apr 25, 2025 am 12:17 AM

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.
