怎么模糊查询日期类型？

[tuzi58]

MatTimer 字段的数据
2009-7-31 12:00:27
2009-7-31 12:00:27
2009-7-31 12:00:27
2009-7-31 12:00:27
2009-7-30 12:00:28
2009-7-30 12:00:28
2009-7-30 12:00:28
2009-7-31 12:00:27
2009-7-31 12:00:27
文本框接收的是 年月日的格式，不带时分秒
用模糊查询 查询出2009-7-31的数据？怎么写Sql语句啊？

--日期转换参数,值得收藏
select CONVERT(varchar, getdate(), 120 )
2004-09-12 11:06:08

select replace(replace(replace(CONVERT(varchar, getdate(), 120 ),'-',''),' ',''),':','')
20040912110608

select CONVERT(varchar(12) , getdate(), 111 )
2004/09/12

select CONVERT(varchar(12) , getdate(), 112 )
20040912

select CONVERT(varchar(12) , getdate(), 102 )
2004.09.12

其它我不常用的日期格式转换方法:

select CONVERT(varchar(12) , getdate(), 101 )
09/12/2004

select CONVERT(varchar(12) , getdate(), 103 )
12/09/2004

select CONVERT(varchar(12) , getdate(), 104 )
12.09.2004

select CONVERT(varchar(12) , getdate(), 105 )
12-09-2004

select CONVERT(varchar(12) , getdate(), 106 )
12 09 2004

select CONVERT(varchar(12) , getdate(), 107 )
09 12, 2004

select CONVERT(varchar(12) , getdate(), 108 )
11:06:08

select CONVERT(varchar(12) , getdate(), 109 )
09 12 2004 1

select CONVERT(varchar(12) , getdate(), 110 )
09-12-2004

select CONVERT(varchar(12) , getdate(), 113 )
12 09 2004 1

select CONVERT(varchar(12) , getdate(), 114 )
11:06:08.177

select *
from tb
where convert(varchar(10),MatTimer,120)='2009-07-31'
不行啊，还是查不出数据，数据带时分秒的，如果用不带时分秒的就查不出来。
select *
from Matter
where convert(varchar(10),MatTimer,120) like '2009-7-31 %'也不行啊？？

--> 测试数据：[TB]
if object_id('[TB]') is not null drop table [TB]
create table [TB]([MatTimer] datetime)
insert [TB]

select '2009-7-31 12:00:27' union all

select '2009-7-31 12:00:27' union all
select '2009-7-31 12:00:27'

select * from TB where replace(convert(varchar(10),[MatTimer],120),'-0','-')='2009-7-31'

drop table TB
