between and 函数

例子：

select * from table_test where creatdate between to_date('2009-11-1 8:47:14','yyyy-mm-dd hh24:mi:ss') and to_date('2009-12-1 8:47:14','yyyy-mm-dd hh24:mi:ss') 

推荐使用：

select * from table_test where creatdate >= to_date('2009-11-01 8:47:14','yyyy-MM-DD') and creatdate <= to_date('2002-03-01' ,'YYYY-MM-DD');

用between...and...的函数可能会慢些 。
