from sys.databases db我不完全知道效率是什么意思，但这很简单，对我有用：
SELECT
DB_NAME(db.database_id) DatabaseName,
(CAST(mfrows.RowSize AS FLOAT)*8)/1024 RowSizeMB,
(CAST(mflog.LogSize AS FLOAT)*8)/1024 LogSizeMB,
(CAST(mfstream.StreamSize AS FLOAT)*8)/1024 StreamSizeMB,
(CAST(mftext.TextIndexSize AS FLOAT)*8)/1024 TextIndexSizeMB
FROM sys.databases db
LEFT JOIN (SELECT database_id, SUM(size) RowSize FROM sys.master_files WHERE type = 0 GROUP BY database_id, type) mfrows ON mfrows.database_id = db.database_id
LEFT JOIN (SELECT database_id, SUM(size) LogSize FROM sys.master_files WHERE type = 1 GROUP BY database_id, type) mflog ON mflog.database_id = db.database_id
LEFT JOIN (SELECT database_id, SUM(size) StreamSize FROM sys.master_files WHERE type = 2 GROUP BY database_id, type) mfstream ON mfstream.database_id = db.database_id
LEFT JOIN (SELECT database_id, SUM(size) TextIndexSize FROM sys.master_files WHERE type = 4 GROUP BY database_id, type) mftext ON mftext.database_id = db.database_id结果如下：
DatabaseName RowSizeMB LogSizeMB StreamSizeMB TextIndexSizeMB

这是一个简单，快速和可靠的查询，它将以美观，易读的输出形式提供所有数据库和日志文件的名称，大小以及数据库状态（例如ONLINE）：
SELECT
D.name,
F.Name AS FileType,
F.physical_name AS PhysicalFile,
F.state_desc AS OnlineStatus,
CAST(F.size AS bigint) * 8*1024 AS SizeInBytes,
CAST((F.size*8.0)/1024/1024 AS decimal(18,3)) AS SizeInGB
FROM
sys.master_files F
INNER JOIN sys.databases D ON D.database_id = F.database_id
ORDER BY SizeInBytes desc数据库总大小排序Desc

当然，您需要的是：
select d.name, case when m.type = 0 then 'Data' else 'Log' end, m.size * 8 / 1024
from sys.master_files m JOIN sys.databases d ON d.database_id = m.database_id或者，如果您不想使用日志：
select d.name, m.size * 8 / 1024
from sys.master_files m JOIN sys.databases d ON d.database_id = m.database_id and m.type =0请找到更多详细信息或从以下链接下载脚本 https://gallery.technet.microsoft.com/SIZE-OF-ALL-DATABASES-IN-0337f6d5#content

from sys.databases d

inner join sys.master_files m1 on m1.database_id = d.database_id
where m0.type = 0 and m1.type = 1
group by d.name, d.database_id
order by d.database_id更好，更简单的一个
SELECT [Database Name] = DB_NAME(database_id),

GROUP BY GROUPING SETS

) ORDER BY DB_NAME(database_id), Type_Desc DESC它将为您分别提供数据文件和日志文件的大小，如下所示
