SqlServer清除日志并收缩数据库

在sqlserver 数据库的使用过程中，特别是频繁更新的系统中，会产生大量的日志文件。
由于商业化的运作，我们的数据库都是有备份的，在隔一段时间之后，我们就可以把日志数据清除掉。由于现在很多时候我们使用的都是虚拟主机，空间商在安全策略上做了限制，导致没有办法清除我们的数据库日志。
唯一的办法就是利用dbower的权限打开查询分析器，使用如下的Sql语句就可以清空并收缩你的数据库空间了：
1.清空日志
DUMP TRANSACTION [yourdbname] WITH NO_LOG;
2.截断数据库日志
BACKUP LOG [yourdbname]WITH NO_LOG;
3.收缩数据库
DBCC SHRINKDATABASE([yourdbname]);
PS：以上Sql语句的顺序不能打乱

Data type differences involve differences in numeric types, character types, and date and time types. SQL statement differences are reflected in result set limitations, data insertion, update and delete operations, etc. Other differences include how identity columns, views, and stored procedures are created.

This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.
