匿名通过本文主要向大家介绍了数据库,记录数等相关知识,希望本文的分享对您有所帮助
说到如何得到表的行数,大家首先想到的应该是select count(*) from table1....
但是如何得到某个数据库所有的表的记录数,你要是用上面的方法估计得累死了。呵呵下面提供如何借用sysindexes和sysobjects表来得到某个数据库每个表记录数的方法:
先给出SQL Server 2000版本的:
代码如下:
SELECT o.NAME,
i.rowcnt
FROM sysindexes AS i
INNER JOIN sysobjects AS o ON i.id = o.id
WHERE i.indid < 2
AND OBJECTPROPERTY(o.id, 'IsMSShipped') = 0
ORDER BY o.NAME
SQL Server2005/8版本的SQL 语句:
代码如下:
SELECT o.name,
ddps.row_count
FROM sys.indexes AS i
INNER JOIN sys.objects AS o ON i.OBJECT_ID = o.OBJECT_ID
INNER JOIN sys.dm_db_partition_stats AS ddps ON i.OBJECT_ID = ddps.OBJECT_ID
AND i.index_id = ddps.index_id
WHERE i.index_id < 2
AND o.is_ms_shipped = 0
ORDER BY o.NAME
赶快试试吧,肯定和你count(*)得到的结果相同。
