SQL Server查詢錶行數

方式一：（表大時較慢）

select count(*) as rows
from table_name

方式二：(數據庫裏本身存的信息，速度較快）

SELECT a.name, b.rows,b.indid
FROM sysobjects AS a
INNER JOIN sysindexes AS b
ON a.id = b.id
WHERE b.indid in (0,1)
and a.name = 'table_name'
ORDER BY a.name,b.rows DESC

如查詢表DM_FACT_SALES的數據行數

SELECT a.name, b.rows,b.indid
FROM sysobjects AS a
INNER JOIN sysindexes AS b
ON a.id = b.id
WHERE b.indid in (0,1)
and a.name = 'DM_FACT_SALES'
ORDER BY a.name,b.rows DESC
