數據庫表名及行數統計

SQLServer：

USE 數據庫名　　　　
SELECT a.name, b.rows

FROM sysobjects AS a INNER JOIN sysindexes AS b ON a.id = b.id

WHERE (a.type = 'u') AND (b.indid IN (0, 1))

ORDER BY b.rows DESC

Oracle：
DBA權限下可以查詢dba_tables，裏面有個num_rows列

select table_name,num_rows from dba_tables;

條件可以根據自己需要來加
不過，num_rows列並不是事實更新的，好像是1小時更新一次，查新之前最好先ANALYZE下

analyze table xxx compute statistics;
