Answer 3

I think

For example, I've an Order table with a DateTime field called OrderDate. I want to retrieve all orders where the order date is equals to 01/01/2006. What's the best way?

1. WHERE DateDiff(dd, OrderDate, '01/01/2006') = 0
2. WHERE Convert(varchar(20), OrderDate, 101) = '01/01/2006'
3. WHERE Year(OrderDate) = 2006 AND Month(OrderDate) = 1 and Day(OrderDate)=1
4. WHERE OrderDate LIKE '01/01/2006%'
5. WHERE OrderDate >= '01/01/2006'  AND OrderDate < '01/02/2006'
6. ...

In my opinion the best way in terms of performances is the 5

WHERE OrderDate >= '01/01/2006'  AND OrderDate < '01/02/2006'

Answer 4

hi vishnu,

Use the

DATEDIFF ( datepart , startdate , enddate )

function here the datepart can be days, month or years so you have to mention the days.
and startdate will be date of you have changed your password last time and the end date will be the +30 days of current date.
now you can check it for if 30 days are over or today is last date.

difference the todays date with end date. if the value is +ve then no need to show the link and if its -ve or 0 then show the link for change password.

Hope this make sense to you.


Thanks.
