access2007数据库用SQL语句查询时间段内的数据

用VB6中ADO控件链接access2007数据库，通过“时间”字段查询下列数据。
时间 数值
2010-1-1 00:01:00 1
2010-1-1 00:02:00 2
2010-1-1 00:03:00 3
2010-1-1 00:04:00 4
2010-1-1 00:05:00 5
2010-1-1 00:06:00 6
2010-1-1 00:07:00 7
2010-1-1 00:08:00 8
2010-1-1 00:09:00 9
2010-1-1 00:10:00 10
需要的查询结果是
2010-1-1 00:03:00 3
2010-1-1 00:04:00 4
2010-1-1 00:05:00 5
2010-1-1 00:06:00 6
2010-1-1 00:07:00 7
2010-1-1 00:08:00 8
代码如下：
dim Cnn As New ADODB.Connection
dim RS1 As New ADODB.Recordset
Cnn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;" + "Data Source=" + App.Path +"\data\data.accdb" + ";Persist Security Info=False;"
Cnn.Mode = adModeReadWrite
Cnn.Open

If Cnn.State = adStateOpen Then
Dim D1 As Date, D2 As Date
D1 = CDate("2010-1-1 00:03:00")
D2 = CDate("2010-1-1 00:08:00")
sql = "SELECT 数值 FROM opt WHERE 时间 between " & D1 & " AND " & D2 & " ORDER BY 时间"
RS1.Open sql, Cnn, 1, 3
end if

但是执行的时候总是报错“语法错误（操作符丢失）在查询表达式 ‘时间 between 2010-1-1 00:03:00 AND 2010-1-1 00:08:00’中”

尝试过更改D1,D2为String类型，报错类型不符，把数据库中时间字段改成文本用文本查询，查不到记录。各位帮帮忙，看看这段SQL语句怎么写才能查到数据，多谢!

Answer 1

sql = "SELECT 数值 FROM opt WHERE 时间 between '" & D1 & "' AND '" & D2 & "' ORDER BY 时间"

Answer 2

sql = "SELECT 数值 FROM opt WHERE 时间 between #" & D1 & "# AND #" & D2 & "# ORDER BY 时间" 时间类型要加#号

Answer 3

用#代替&试下
