SelectCommand problem (code) how do I code this

Question

I have a code on a code behind page in asp.net like the one below. 
  foreach (T_activities k in dc.T_activitiess.Where(p => p.date <= e.Day.Date && p.dateontill >= e.Day.Date && p.show == "yes").OrderBy(o=>o.starttime))
This codes shows the items in a calendar and if the dateontill has a date it shows this item untill that date written in dateontill together with the items in date. 
But now the calendar has moved on my website and this select date in now on my .aspx page. 
SelectCommand="SELECT [show], [date], [starttime], [dateontill] [art], [subject, [place] FROM [T_activities ] WHERE (([date] = ?) AND ([show] = ?)) order by starttime">
I cannot figure out how to make the select command where I show allt the items for date and also show the items on other days if the dateontill is filled. 
pls help
regards
Fili

The alias e has no object assigned to it. Apart from it if you need records which lies under a specific date range then.
SELECT <COLUMNS>
FROM <TABLE_NAME> JOIN <TABLE_NAME> ON <CONDITION>
WHERE
<DATE COLUMN 1> >= [DATE START PARAMETER] AND
<DATE COLUMN 2> <= [DATE END PARAMETER]
[AND OTHER FILTERS.....]
Chaos isn’t a pit. Chaos is a ladder. Many who try to climb it fail and never get to try again. The fall breaks them. And some are given a chance to climb, but they refuse. They cling to the realm, or the gods, or love. Illusions. Only the ladder is real.
The climb is all there is.
