sql 在使用中每次查询都会生成日志,但是如果你长久不去清理,可能整个硬都堆满哦,笔者就遇到这样的情况,直接网站后台都进不去了。下面我们一起来学习一下如何清理这个日志吧
SQL2005清空删除日志:
复制代码 代码如下:
Backup Log DNName with no_log '这里的DNName是你要收缩的数据库名,自己注意修改下面的数据库名,我就不再注释了。
go
dump transaction DNName with no_log
go
USE DNName
DBCC SHRINKFILE (2)
Go
SQL2008清空删除日志:
'在SQL2008中清除日志就必须在简单模式下进行,等清除动作完毕再调回到完全模式。
复制代码 代码如下:
USE [master]
GO
ALTER DATABASE DNName SET RECOVERY SIMPLE WITH NO_WAIT
GO
ALTER DATABASE DNName SET RECOVERY SIMPLE --简单模式
GO
USE DNName
GO
DBCC SHRINKFILE (N'DNName_Log' , 11, TRUNCATEONLY)
GO
'这里的DNName_Log 如果不知道在sys.database_files里是什么名字的话,可以用以下注释的语句进行查询
'USE DNName
'GO
'SELECT file_id, nameFROM sys.database_files;
'GO
USE [master]
GO
ALTER DATABASE DNName SET RECOVERY FULL WITH NO_WAIT
GO
ALTER DATABASE DNName SET RECOVERY FULL --还原为完全模式
GO
sqlserver2000压缩日志

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.
