datetime format

Hi.
I have two parameters called StartDate and EndDate.These parameters are from datetime type.
I want to view the records between these dates.I have some questions:

1)In the database, these parameters' values are like 15.11.1984 23:59:14. It has time value near the date value.But I don't want to view the time value.I only want the date part.

2)In the preview tab, I choose a date clicking the calendar image near the parameter textbox.
For example I choose 02.05.2001 and when I click the view report button, it changes to 05.02.2001.So there is a format difference.I want it to show like dd.mm.yyyy

3)By default, if the user doesn't enter a date, I want to view all the records.Any idea about this?

Thanks!

Try doing a convert on your database datetime field similar to this in your query

convert(datetime, "datefield", 104)

This will format the date as dd.mm.yyyy. You can also do this on the parameter value so they are both in the same format. Your query would look something like this:

select * from table where convert(datetime, "datefield", 104) >= convert(datetime, @.StartDate, 104) and convert(datetime, "datefield", 104) <= convert(datetime, @.EndDate,104)

To display all records you can set the default values to the maximum and minimum dates in your database. The issue with this is that everytime the report is opened, it will automatically run for all dates. Not sure how to make it work only if the user doesn't select dates.

|||kmcclung thanks for the reply.
But it didn't work.
I wrote convert(datetime, myDateField, 104) and then tried the third parameter for 103, 4, ...
But it didn't change.
Then I realized that it is not dependent on that number.
It uses only the default datetime format.
The records in my database are like dd.mm.yyyy hh:mm:ss
And after I used the CONVERT function NOTHING changed.
I only want the date part to be visible.(only want this)
And the second problem is that as I said before when I click the calendar button near the date texbox area and select a date like 15.12.2001 then it is written to textbox like 12.15.2001.
And because of not existing a month number like 15 an error occurs.
I mean that I want to change that calendar's format.

How can I correct this?|||What type of database you are using?|||

0) It sounds like your database is NOT storing dates with a DATETIME format. Why not?

1) To take '15.11.1984 23:59:14' and store it as a DATETIME with time stripped off (set to midnite):

CONVERT(DATETIME, CAST(CONVERT(DATETIME, '15.11.1984 23:59:14', 104) AS INT))
