------解决方案--------------------
一般都是因为连接条件没设置齐全导致记录几何增长
------解决方案--------------------
a innert join b 的a表与b表的连接条件没设置
------解决方案--------------------
数据量太大、、、、
------解决方案--------------------
太多数据了吧 你要加上 top 10 速度才更快呢
------解决方案--------------------
SELECT count(*)
FROM dbo.stat_session AS a
INNER JOIN dbo.stat_engine AS b ON CHARINDEX(b.url, a.frmurl, 8)> 0
WHERE a.keyid IS NOT NULL AND b.ID IN (1, 2, 8)
AND ISNULL(dbo.convertvalue(a.sid), 0)> 0 AND a.cid IN (SELECT ID FROM dt_company)
--看看数据量有多大
------解决方案--------------------
就是用count(*)看看有多少条数据先
------解决方案--------------------
海量数据啊.呵呵.
实际表中有没有这么多数据呢?
如果没有的话,那么就是语句连接条件设置不全,
或者是语句连接条件未进行优化.
