这里有一些SQL逻辑基本上会以GB为单位提供数据，日志和总数（数据+日志）。另外，所有尺寸均为圆形（天花板）。

用于引用的总计的SQL逻辑需要注意：1GB内的差异舍入为1GB，如果找到的差异少于1GB，则数据和日志文件之间的总数不会超过1GB。

Here’s some SQL logic that will basically give you the data, log, and total (data + log) in GB. Additionally; all sizes are rounded (ceiling).

SQL logic for totals for reference Note: Variances within 1GB are rounded as 1GB and totals between data & log files will not exceed 1gb if fewer than 1GB variances are found.

Logic

use master;
set nocount on
select
[name] = upper(sd.name)
,   [data   - in gb]    = ceiling(sum(case when type = 0 then (smf.size*8)/1024.0/1024.0 else 0 end))
,   [log    - in gb]    = ceiling(sum(case when type = 1 then (smf.size*8)/1024.0/1024.0 else 0 end)) , [total  - in gb]    = ceiling(sum(smf.size * 8.00/1024.00/1024.00)) from
sys.databases sd join sys.master_files smf on sd.database_id = smf.database_id where
sd.source_database_id is null
and sd.name not in ('master', 'model', 'msdb', 'tempdb')
group by
sd.name
order by
[data   - in gb] desc
