between operator

Hi,

I'm having problems using the between operator in a query statement.

Select *
from <mytable>
where date between @.date1 and @.date2

The date values with a hour specified, aren't returned. What is the approach you would recommend here?

Thx

EDIT: by playing with this problem I've figured out I can append the hour to the date like this: <date> between @.fromDate + '00:00:00' and @.toDate + '23:59:59'

this seem to work, but I'm not sure if this is correct

Select *
from <mytable>
where date >= @.date1 and date < dateadd(d,1,@.date2)

or

Select *
from <mytable>
where date >= @.date1 and date < @.date2 +1

i had a similar problem which i did through the application side:

string weekdate =txtFrom.Text;

string daydate = System.Convert.ToDateTime(txtTo.Text).Add(System.TimeSpan.FromDays(1)).ToString();

and later...

TechnicianViewInboxDataAdapter.SelectCommand.CommandText = tempselecttechnician + " where status = 1 and TechnicianID = " + Session["UserID"].ToString() + "and CallLoggedDT Between '" + weekdate + "' and '" + daydate + "' or TechnicianID = 1 and DepartmentID = 1 and status = 1 and CallLoggedDT Between '" + weekdate + "' and '" + daydate + "' or TechnicianID = 1 and status = 1 and CallLoggedDT Between '" + weekdate + "' and '" + daydate + "' and DepartmentID = " + Session["DepartmentID"].ToString();

this works as well.

the code ends up like this:

SELECT FirstName, LastName, Email, CallNumber, DepartmentName, UserName, Status, TechnicianID, CallLoggedDT, DepartmentID, CallOpenedDT, CallActionedDT, CallClosedDT FROM dbo.TechnicianInboxView where status = 1 and TechnicianID = 2and CallLoggedDT Between '2006/05/30' and '2006/06/07 12:00:00 AM' or TechnicianID = 1 and DepartmentID = 1 and status = 1 and CallLoggedDT Between '2006/05/30' and '2006/06/07 12:00:00 AM' or TechnicianID = 1 and status = 1 and CallLoggedDT Between '2006/05/30' and '2006/06/07 12:00:00 AM' and DepartmentID = 2

You can also use the datediff function and the statement would look like this.

Select * from <mytable> where

datediff(dd,@.date1,<Datefield in the table>)>=0 and datediff(dd,@.date2,<Datefield in the table>)<=0

@.Date can be varchar too and it can be in the format of "mm/dd/yy" also. Need not have the time factor.

where datediff(dd,@.date1,<Datefield in the table>)>=0 and datediff(dd,@.date2,<Datefield in the table>)<=0

Would not recommend doing so in the terms of performace. You will never get index seek over the index for datefield column: it will always index scan at the best.
