前言:
SQL Server 有两种身份验证:一种是WIndows身份验证,Windows身份验证使用Windows上的帐号,并利用其安全令牌进行验证。一种是SQL Server验证,使用SQL Server里面定义的帐号进行身份验证。
实现:
1、在SSMS中,右键【实例名】,选择【属性】,然后找到【安全性】页:
【Windows身份验证】仅接受WIndows帐号,这个是默认打开并且不能关闭的。【SQL Server和Windows身份验证模式】接受WIndows和SQL Server帐号。
2、如果【Windows身份验证】已选,你可以创建SQL Server扽股,但是不能使用,切换身份验证需要重启服务。
原理:
在安装过程中,SQL Server会要求选择身份验证,Windows身份验证是默认的,并且是建议设置,因为不仅能简化管理,并且具有更加高的安全性。你不能禁用Windows身份验证,仅在访问的用户超出本地网络或者可信任域的环境时才使用SQL Server身份验证。
SQL Server帐号在SQL Server内部创建,身份验证和密码验证都由SQL Server负责。
被推荐的方案是使用Windows身份验证,并且在活动目录中定义组,把组添加仅SQL Server中。

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.
