关于查看MSSQL 数据库 用户每个表 占用的空间大小(2)

SELECT  OBJECT_NAME(id) tablename ,
 * reserved / 1024 reserved ,
        RTRIM(8 * dpages / 1024) + 'Mb' used ,
 * ( reserved - dpages ) / 1024 unused ,
 * dpages / 1024 - rows / 1024 * minlen / 1024 free ,
        rows
FROM    sysindexes
WHERE   indid = 1
ORDER BY reserved DESC

运行结果如图：

这里面包含一些索引信息，其实我们只关心表占用磁盘信息，修改后的SQL语句如下：

复制代码 代码如下:

View Code
SELECT  OBJECT_NAME(id) tablename ,
        CASE WHEN reserved * 8 > 1024 THEN RTRIM(8 * reserved / 1024) + 'MB'
             ELSE RTRIM(reserved * 8) + 'KB'
        END DataReserve ,
        CASE WHEN dpages * 8 > 1024 THEN RTRIM(8 * dpages / 1024) + 'MB'
             ELSE RTRIM(dpages * 8) + 'KB'
        END Used ,
        CASE WHEN 8 * ( reserved - dpages ) > 1024
             THEN RTRIM(8 * ( reserved - dpages ) / 1024) + 'MB'
             ELSE RTRIM(8 * ( reserved - dpages )) + 'KB'
        END unused ,
        CASE WHEN ( 8 * dpages / 1024 - rows / 1024 * minlen / 1024 ) > 1024
             THEN RTRIM(( 8 * dpages / 1024 - rows / 1024 * minlen / 1024 )
                        / 1024) + 'MB'
             ELSE RTRIM(( 8 * dpages / 1024 - rows / 1024 * minlen / 1024 ))
                  + 'KB'
        END FREE ,
        rows AS Rows_Count
FROM    sys.sysindexes
WHERE   indid = 1
        AND status = 2066 -- status='18'
ORDER BY reserved DESC

运行结果如下：

有不对的地方欢迎大家拍砖！
