基本:我的MS SQL Server DB的磁盘大小是多少?
更多:我可以快速查看数据在哪里吗?即哪些表,日志等

Answers:
您可能需要从sp_spaceused命令开始。
例如:
sp_spaceused 返回有关数据库总大小的信息
sp_spaceused'MyTable' 返回有关MyTable大小的信息
阅读文档以获取您可以获取的所有信息。您还可以使用sp_msforeachtable命令对所有表一次运行sp_spaceused。
编辑:请注意,该命令有时会返回多个数据集,每个数据集包含不同的统计信息块。
此脚本循环遍历当前数据库中的所有表,并显示每个表占用数据,索引和未使用空间的空间:
http://sqlserverpedia.com/wiki/Calculate_Current_Table_Sizes
您可以在中查看物理文件sys.database_files
。它具有文件的路径和大小(以IIRC块为单位)。
sp_spaceused
将显示单个对象占用了多少空间。
运行此命令以获取每个表的大小:

** File: “GetTableSpaceUsage.sql”
** Name: Get Table Space Useage for a specific schema
** Auth: Robert C. Cain
** Date: 01/27/2008

此代码适用于Microsoft SQL 2005+
运行开始\程序\ Microsoft SQL Server \企业管理器。打开数据库表,在属性%databasename%中,您可以看到位置数据文件和事务文件。
这是一个查询/视图,可获取所有这些信息以及更多信息,而没有任何“邪恶的”游标或循环。;-)

关于如何从GUI进行的操作,有一些描述。
真正的DBA知道:GUI适用于块。
sp_helpdb
返回所有文件名,位置,磁盘空间和类型的记录集。
您还可以从每个数据库的sysfiles表中检索文件名。
