在今年的TechEd大会上，微软宣布SQL Server 2014第一个技术预览版，并且将于本月正式提供下载，而产品正式发布时间初步定在今年年底。新版本最大的亮点是表粒度级别的内存OLTP（On-Line Transaction Processing，联机事务处理系统）和提供实时的大数据分析功能。

负责该项目的微软企业副总裁Quentin Clark表示，内存OLTP源于微软已使用多年的Hekaton，Hekaton是一个完全在内存中的交易型数据库引擎，而该项目将会完全列入到SQL Server 2014中，在性能上，比现在标准的SQL Server服务器可高出50倍。

SQL Server功能演变

Clark还表示，微软将在SQL Server盒子中提供Heakaton的内存OLTP，对用户而言，“在盒子里”意味着用户无需购买专门的软/硬件支持，即可在项目中使用内存OLTP功能。

该版本的另一亮点是混合云端平台的能力，宣称它可藉由备份到Azure及与Azure的随时连结简化云端备份与灾害复原，而且轻易就能把自动部署SQL服务器迁移到Azure的虚拟机上。

在实际开发中，SQL Server团队将会继续致力于columnstore（列存储）性能和数据压缩方面的研发与投资，目前，列存储已经根植于BI服务和Excel工具用于更快的业务观察。

What is MySQL partitioning?Apr 27, 2025 am 12:23 AM

MySQL partitioning improves performance and simplifies maintenance. 1) Divide large tables into small pieces by specific criteria (such as date ranges), 2) physically divide data into independent files, 3) MySQL can focus on related partitions when querying, 4) Query optimizer can skip unrelated partitions, 5) Choosing the right partition strategy and maintaining it regularly is key.

How do you grant and revoke privileges in MySQL?Apr 27, 2025 am 12:21 AM

How to grant and revoke permissions in MySQL? 1. Use the GRANT statement to grant permissions, such as GRANTALLPRIVILEGESONdatabase_name.TO'username'@'host'; 2. Use the REVOKE statement to revoke permissions, such as REVOKEALLPRIVILEGESONdatabase_name.FROM'username'@'host' to ensure timely communication of permission changes.

Explain the differences between InnoDB and MyISAM storage engines.Apr 27, 2025 am 12:20 AM

InnoDB is suitable for applications that require transaction support and high concurrency, while MyISAM is suitable for applications that require more reads and less writes. 1.InnoDB supports transaction and bank-level locks, suitable for e-commerce and banking systems. 2.MyISAM provides fast read and indexing, suitable for blogging and content management systems.

What are the different types of JOINs in MySQL?Apr 27, 2025 am 12:13 AM

There are four main JOIN types in MySQL: INNERJOIN, LEFTJOIN, RIGHTJOIN and FULLOUTERJOIN. 1.INNERJOIN returns all rows in the two tables that meet the JOIN conditions. 2.LEFTJOIN returns all rows in the left table, even if there are no matching rows in the right table. 3. RIGHTJOIN is contrary to LEFTJOIN and returns all rows in the right table. 4.FULLOUTERJOIN returns all rows in the two tables that meet or do not meet JOIN conditions.

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?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*.
