相关的唯一答案this question，我可以建议是这样的：

SELECT 
    s.name AS SchemaName, 
    t.name AS TableName, 
    p.rows AS RowCounts, 
    a.total_pages * 8 AS TotalSpaceKB, 
    a.used_pages * 8 AS UsedSpaceKB, 
    a.total_pages * 8/p.rows AS eachRowTotalSpaceKB, 
    a.used_pages * 8/p.rows AS eachRowUsedSpaceKB, 
    a.total_pages * 8/p.rows * (select * from dbo.PictureTable where SchoolCode=1001) AS queryTotalSpaceKB, 
    a.used_pages * 8/p.rows * (select * from dbo.PictureTable where SchoolCode=1001) AS queryTotalSpaceKB 
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 
    s.name = 'dbo' AND 
    t.name = 'PictureTable';

您可以通过使用DATALENGTH这样让您的数据的长度在一个领域：

SELECT SUM(DATALEGTH(PictureTable_ID)) + SUM(DATALEGTH(Groupcourses_ID)) +SUM(DATALEGTH(per_ID)) + SUM(DATALEGTH(School_ID)) + SUM(DATALEGTH(AcademicYear_ID)) + SUM(DATALEGTH(PictureTable_Description)) + SUM(DATALEGTH(SchoolCode)) As rowSizes 
FROM PictureTable 
WHERE (SchoolCode = 1001);
