SQL语句以前在学校的时候都学过,时间久了就有点记不清了。

今天用time Like '2008-06-01%'语句来查询该天的所有数据,被提示语句错误。查了一下才发现该模糊查询只能用于String类型的字段。
自己也查阅了一些资料。关于时间的模糊查询有以下三种方法:
1.Convert转成String,在用Like查询。
select * from table1 where convert(varchar,date,120) like '2006-04-01%'
2.Between
select * from table1 where time between '2006-4-1 0:00:00' and '2006-4-1 24:59:59'";
3 datediff()函数
select * from table1 where datediff(day,time,'2006-4-1')=0
第一种方法应该适用与任何数据类型;
第二种方法适用String外的类型;
第三种方法则是为date类型定制的比较实用快捷的方法。
