如何确定SQL Server数据库的大小？

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

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。

最简单的方法（无需输入！）：在Management Studio的SQL 2005/8中，右键单击数据库，选择“报告”，“标准报告”，“磁盘使用情况”（也按“顶层表”，“表”和“分区”）。

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：

**    Name: Get Table Space Useage for a specific schema
**    Auth: Robert C. Cain
**    Date: 01/27/2008
**
**    Desc: Calls the sp_spaceused proc for each table in a schema and returns

**
**    Called by:
**     n/a – As needed

**    Input Parameters:
**     In the code check the value of @schemaname, if you need it for a

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。
