如果您正在使用SQL Server 2005及更高版本,您还可以使用:

SELECT 
    t.NAME AS TableName,
    i.name as indexName,
    p.[Rows],
    sum(a.total_pages) as TotalPages, 
    sum(a.used_pages) as UsedPages, 
    sum(a.data_pages) as DataPages,
    (sum(a.total_pages) * 8) / 1024 as TotalSpaceMB, 
    (sum(a.used_pages) * 8) / 1024 as UsedSpaceMB, 
    (sum(a.data_pages) * 8) / 1024 as DataSpaceMB
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
WHERE 
    t.NAME NOT LIKE 'dt%' AND
    i.OBJECT_ID > 255 AND   
    i.index_id <= 1
GROUP BY 
    t.NAME, i.object_id, i.index_id, i.name, p.[Rows]
ORDER BY 
    object_name(i.object_id) 

在我看来,它比sp_msforeachtable输出更容易处理.

我在http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=21021上找到的片段帮助了我:

select t.name TableName, i.rows Records
from sysobjects t, sysindexes i
where t.xtype = 'U' and i.id = t.id and i.indid in (0,1)
order by TableName;

要在SQL Management Studio中获取该信息,请右键单击该数据库,然后选择"报告" - >"标准报告" - >"按表排列的磁盘使用情况".

Answer 4

SELECT 
    T.NAME AS 'TABLE NAME',
    P.[ROWS] AS 'NO OF ROWS'
FROM SYS.TABLES T 
INNER JOIN  SYS.PARTITIONS P ON T.OBJECT_ID=P.OBJECT_ID;

如此处所示,这将返回正确的计数,其中使用元数据表的方法仅返回估计值.

    CREATE PROCEDURE ListTableRowCounts 
    AS 
    BEGIN 
        SET NOCOUNT ON 

        CREATE TABLE #TableCounts
        ( 
            TableName VARCHAR(500), 
            CountOf INT 
        ) 

        INSERT #TableCounts
            EXEC sp_msForEachTable 
                'SELECT PARSENAME(''?'', 1), 
                COUNT(*) FROM ? WITH (NOLOCK)' 

        SELECT TableName , CountOf 
            FROM #TableCounts
            ORDER BY TableName 

        DROP TABLE #TableCounts
    END
    GO
