60 = SQL Server 6.0
65 = SQL Server 6.5
70 = SQL Server 7.0
80 = SQL Server 2000
90 = SQL Server 2005
对于 SQL Server 2005 的所有安装,默认的兼容级别为 90。SQL Server 2005 中创建的数据库即设置为该级别,除非 model 数据库有更低的兼容级别。在将数据库从 SQL Server 的任何早期版本升级到 SQL Server 2005 之后,该数据库将保留其现有的兼容级别。这既适用于系统数据库也适用于用户数据库。可使用 sp_dbcmptlevel 将数据库的兼容级别更改为 90。
select compatibility_level from sys.databases where NAME='test'
--80
解决:
EXEC sp_dbcmptlevel test, 90;
GO

Stored procedures are precompiled SQL statements in MySQL for improving performance and simplifying complex operations. 1. Improve performance: After the first compilation, subsequent calls do not need to be recompiled. 2. Improve security: Restrict data table access through permission control. 3. Simplify complex operations: combine multiple SQL statements to simplify application layer logic.

The working principle of MySQL query cache is to store the results of SELECT query, and when the same query is executed again, the cached results are directly returned. 1) Query cache improves database reading performance and finds cached results through hash values. 2) Simple configuration, set query_cache_type and query_cache_size in MySQL configuration file. 3) Use the SQL_NO_CACHE keyword to disable the cache of specific queries. 4) In high-frequency update environments, query cache may cause performance bottlenecks and needs to be optimized for use through monitoring and adjustment of parameters.

The reasons why MySQL is widely used in various projects include: 1. High performance and scalability, supporting multiple storage engines; 2. Easy to use and maintain, simple configuration and rich tools; 3. Rich ecosystem, attracting a large number of community and third-party tool support; 4. Cross-platform support, suitable for multiple operating systems.

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.
