我继承了一个相当大的SQL Server数据库。考虑到它包含的数据,它似乎比我预期的要占用更多的空间。

是否有一种简单的方法来确定每个表占用的磁盘空间?

我在marc_s答案的顶部添加了几列:

with fs
as
(
select i.object_id,
        p.rows AS RowCounts,
        SUM(a.total_pages) * 8 AS TotalSpaceKb
from     sys.indexes i INNER JOIN 
        sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id INNER JOIN 
         sys.allocation_units a ON p.partition_id = a.container_id
WHERE 
    i.OBJECT_ID > 255 
GROUP BY 
    i.object_id,
    p.rows
)

SELECT 
    t.NAME AS TableName,
    fs.RowCounts,
    fs.TotalSpaceKb,
    t.create_date,
    t.modify_date,
    ( select COUNT(1)
        from sys.columns c 
        where c.object_id = t.object_id ) TotalColumns    
FROM 
    sys.tables t INNER JOIN      
    fs  ON t.OBJECT_ID = fs.object_id
WHERE 
    t.NAME NOT LIKE 'dt%' 
    AND t.is_ms_shipped = 0
ORDER BY 
    t.Name

也许表格有更多的分区文件,必须显示文件顺序

SELECT
  T1.Name                                       AS TableName,
  T5.Name                                       AS SchemaName,
  T3.partition_number                           AS PartionNumber,   
  T3.Rows                                       AS RowsCount,
  SUM(T4.total_pages) * 8                       AS TotalSpaceKB,
  SUM(T4.used_pages) * 8                        AS UsedSpaceKB,
  (SUM(T4.total_pages) - SUM(T4.used_pages)) * 8 AS UnusedSpaceKB
FROM
  sys.objects T1  INNER JOIN 
  sys.indexes T2 ON T1.object_id = T2.object_id  INNER JOIN 
  sys.partitions T3 ON T2.object_id = T3.object_id AND T2.index_id = T3.index_id  INNER JOIN
  sys.allocation_units T4 ON T3.partition_id = T4.container_id LEFT JOIN
  sys.schemas T5 ON T1.schema_id = T5.schema_id
WHERE
  T1.type='U'
GROUP BY
  T1.Name, T5.Name, T3.Rows,T3.partition_number
ORDER BY
  T1.Name,T3.partition_number;

从使用OSQL的命令提示符:

OSQL -E -d <*databasename*> -Q "exec sp_msforeachtable 'sp_spaceused [?]'" > result.txt
SELECT 
    t.NAME AS TableName,
    s.Name AS SchemaName,
    p.rows,
    SUM(a.total_pages) * 8 AS TotalSpaceKB, 
    CAST(ROUND(((SUM(a.total_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS TotalSpaceMB,
    SUM(a.used_pages) * 8 AS UsedSpaceKB, 
    CAST(ROUND(((SUM(a.used_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS UsedSpaceMB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB,
    CAST(ROUND(((SUM(a.total_pages) - SUM(a.used_pages)) * 8) / 1024.00, 2) AS NUMERIC(36, 2)) AS UnusedSpaceMB
FROM 
    sys.tables t
INNER JOIN      
    sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id
LEFT OUTER JOIN 
    sys.schemas s ON t.schema_id = s.schema_id
WHERE 
    t.NAME NOT LIKE 'dt%' 
    AND t.is_ms_shipped = 0
    AND i.OBJECT_ID > 255 
GROUP BY 
    t.Name, s.Name, p.Rows
ORDER BY 
    TotalSpaceMB DESC, t.Name

对于Azure,我使用了:

您应该有SSMS v17.x+

我使用;

正如用户Sparrow所提到的:

打开数据库>并选择表,然后按F7键你应该看到行数作为:

此处的SSMS连接到Azure数据库

要获取一个数据库中的所有表大小,可以使用以下查询:

Exec sys.sp_MSforeachtable ' sp_spaceused "?" '

您可以将其更改为将所有结果插入临时表,然后从临时表中进行选择。

Insert into #TempTable Exec sys.sp_MSforeachtable ' sp_spaceused "?" ' 
Select * from #TempTable
