前言:

SQL Server端点(Endpoint)是出入SQL Server的门户,通过端点,任何东西可以在网络和SQL Server之间传输。端点可以是系统或者用户自定义的,其中系统端点允许使用T-SQL连接SQL Server并发送查询。

端点使用特定的协议定义,可以是HTTP或者TCP,从SQL Server 2012开始HTTP端点被移除出内置的Web Services功能中,仅能使用TCP端点。

通常使用自定义端点的目的有:

TCP 请求。本文介绍这种,可以用于建立专用或安全的SQL Server连接。 Service Broker 数据库镜像

实现:

1. 在查询窗口中输入下面语句:

CREATE ENDPOINT myTSQLEndpoint 
STATE = started 
AS TCP ( 
  LISTENER_PORT = 8080, 
  LISTENER_IP = (127.0.0.1) 
  ) 
FOR TSQL ();
Copy after login

2. 执行后会收到消息如下,意味着所有通过默认T-SQL端点连接的登录都会失去所有权限,你需要使用下面语句授权:

GRANT CONNECT ON ENDPOINT::[TSQL Default TCP] to [public];
Copy after login

消息:

创建 TSQL 端点将导致撤销 'TSQL Default TCP' 端点上的所有 'Public' 连接权限。如果此端点上需要 'Public' 访问权限,请使用'GRANT CONNECT ON ENDPOINT::[TSQL Default TCP] to [public]'重新应用此权限。
Copy after login

3. 可以使用下面语句查询端点情况:

SELECT * FROM sys.tcp_endpoints;
Copy after login

4. 可以使用ALTER ENDPOINT命令启动或停止端点:

ALTER ENDPOINT [TSQL Default TCP] STATE = STOPPED;
Copy after login

原理:

当SQL Server 安装完毕是,会为每个网络协议创建对应的SQL Server系统端点。访问端点的权限是赋予给Public 服务器角色。每个SQL Server登录都具有Public角色权限,可以通过下面语句进行授权和回收:

REVOKE CONNECT ON ENDPOINT::[TSQL Default TCP] to [public]; 
GRANT CONNECT ON ENDPOINT::[TSQL Default TCP] to [a_specific_login];
Copy after login

When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Explain InnoDB Full-Text Search capabilities. Explain InnoDB Full-Text Search capabilities. Apr 02, 2025 pm 06:09 PM

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Can I install mysql on Windows 7 Can I install mysql on Windows 7 Apr 08, 2025 pm 03:21 PM

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

Difference between clustered index and non-clustered index (secondary index) in InnoDB. Difference between clustered index and non-clustered index (secondary index) in InnoDB. Apr 02, 2025 pm 06:25 PM

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values ​​and pointers to data rows, and is suitable for non-primary key column queries.

MySQL: Simple Concepts for Easy Learning MySQL: Simple Concepts for Easy Learning Apr 10, 2025 am 09:29 AM

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Apr 02, 2025 pm 07:05 PM

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.

The relationship between mysql user and database The relationship between mysql user and database Apr 08, 2025 pm 07:15 PM

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

Can mysql and mariadb coexist Can mysql and mariadb coexist Apr 08, 2025 pm 02:27 PM

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.
