sp_spaceused可以获取表、索引视图或整个数据库使用的磁盘空间的信息。

例如：

USE MyDatabase; GO

EXEC sp_spaceused N'User.ContactInfo'; GO

这将报告ContactInfo表的磁盘使用情况信息。

要同时对所有表使用此选项：

USE MyDatabase; GO

sp_msforeachtable 'EXEC sp_spaceused [?]' GO

您还可以从SQL Server的右键单击“标准报告”功能中获取磁盘使用情况。要获取此报告，请从对象资源管理器中的服务器对象导航，向下移动到数据库对象，然后右键单击任何数据库。从出现的菜单中，选择“报告”，然后选择“标准报告”，再选择“磁盘分区使用情况：[DatabaseName]”。

从使用OSQL的命令提示符：

OSQL -E -d <*databasename*> -Q "exec sp_msforeachtable 'sp_spaceused [?]'" > result.txt

如果您只关心数据库中的空浪费空间，而不关心单个表，则可以考虑以下问题：

如果数据库经历了大量的数据插入和删除，可能与ETL情况类似，这将导致数据库中有太多未使用的空间，因为文件组会自动增长，但不会自动收缩。

您可以通过使用数据库的财产页面来查看是否是这种情况。您可以收缩（右键单击数据库>任务>收缩）并收回一些空间。但是，如果根本原因仍然存在，则数据库将增长（并花费额外的时间尝试增长，直到增长到足够的速度，所以不要这样做）
