可以结合sp_MSforeachdb再遍历所有用户数据库查看所有表的尺寸大小，注意它的参数@sql不能超过nvarchar(2000)，这里就不贴出代码了。

另外还可以定期运行并将结果保存下来，以便观察数据变化趋势。

查询单个数据库的所有用户表尺寸大小：

复制代码 代码如下:

Select @@servername as ServerName,db_name() as DBName ,object_id as ObjectID, schema_name(schema_id) as SchName, name as TableName

,Rowcnt as Rows,Columns,Indexes,RowLength

,ReservedKb, TableUsedKb

,UsedKb-TableUsedKb as IndexUsedKb,ReservedKb-UsedKb as UnusedKb

,create_date as CreateDate,modify_date as LastModifiedDate, getutcdate() as TrackingUTCTime

From
