Hi,
I am trying to pull data from the datetime type field -"Tran_Date" and which contains data like this - "2008-12-18 16:34:26.717"

I am writing the following queries, but none of them are returning any data:

select * from MonthlyExpense.dbo.MonthlyExpense
where Tran_Date=CONVERT(datetime,'2008-12-18 1:55:51 PM',121)

OR

select * from MonthlyExpense.dbo.MonthlyExpense
where Tran_Date =CAST('2008-12-18 16:34:26.717' as datetime)

I also want data to be retrieved based on the Date part of the datetime field. Pls help.

try this

select * from MonthlyExpense.dbo.MonthlyExpense
where dateadd(dd,datediff(dd,0,Tran_Date),0) = '2008-12-18'

The above query will retrieve all records which has tran_date as Dec 18th, 2008 irrespective of time ...

Raky, this is simpler

where datediff(dd, Tran_Date, '2008-12-18') = 0

but still doesn't give you access to good index use.
This below let's you use index (if any present) in a good way.

select	*
from	MonthlyExpense.dbo.MonthlyExpense 
where	Tran_Date >= '2008-12-18'
	and Tran_Date < '2008-12-19'

E 12°55'05.63"
N 56°04'39.26"
