T-SQL query help

Posted By:      Posted Date: October 20, 2010    Points: 0   Category :ASP.Net


I have a table that is used to log the hours a person works.  Amongst other fields, it contains a datetime field and an hours (tinyint) field.

I am trying to ascertain the hours a person works between two given dates which is (should be) simple.  My problem is when the hours worked overlap days. 

For instance; Jim starts work on the 1st August at 23:00 for 5 hours.  This means that Jim worked for 1 hour on the 1st and 4 hours on the second.  If I run the report

Select hoursWorked from timeLog where startDate = 2010/08/01, I get 5 returned.  
If I run 
Select hoursWorked from timeLog where startDate = 2010/08/02, I get nothing, as expected.


I have struggled with this for days now and cannot workout how I can get a query that returns 4 when run using the date parameter as 2010/08/02.  Can anyone please advise or point me in the right direction?

How to send an email with information in query string


First I will say I googled (Binged to make Bill happy) for this but could not find anything, perhaps I am not stating what I need correctly;

I have a website that a customer creates orders (for a printing company) and after the order, I would like to email the customer a link to view the status of their order;

I need to send the CustomerID in the link so on the returning page if a CustomerID is detected in the querystring, I "auto login" the client and open the "Dashboard" for the order page for that customer.

Can anyone point me in the right direction as to how to send the link and how to parse the querystring to get the values from the link;

Thank you if you can point me in the right direction.
