不同的机器上,iVR_haoduan的数据和索引都是一样的.
在执行
select * from iVR_haoduan where a<='13722222222' and b>='13711111111'
的时候
为什么1台机器上能用索引(扫描非聚集索引中特定范围的行 用了 idx_a_b),
另外一台机器却不能利用索引(表扫描87% ,)

看来没有高手了,我才是高手
原因应该是 sqlserver sp3 对varchar 的> and < 是不能利用索引的,对int的可以利用.
而sp4的 > and <是可以利用索引的
大家都打sp4吧.

1.重建某个表的所有索引
下例重建 pubs 数据库中 authors 表上所有索引。
DBCC DBREINDEX ('pubs.dbo.authors')
2.更新单个表的所有统计
本示例更新表 authors 上的所有索引分发统计。
UPDATE STATISTICS authors
