With the little data you have posted ... use Books on Line and check the use of the BETWEEN statement


From Books on Line:


test_expression BETWEEN begin_expression AND end_expression

If everything seems to be going well, you have obviously overlooked something.

You will need to use DATEADD as well.

Does this mean you have two columns?
What is the data type of the column(s)?

Let me be a little bit more clear on that...
There are two columns

CurrentDate Date,
Time Varchar(10)


If I do , Select * from Data
Order By Date Desc , Time Desc shows the following results
The result is :
2014-03-26 3:01 AM
2014-03-26 2:01 PM
2014-03-26 2:01 AM
2014-03-26 12:01 PM
2014-03-26 12:01 AM
2014-03-26 11:01 AM *********** Shouldn't this be on top of :01 am?

I need to see the latest Date and Time in an order... If I resolve this I will be able to resolve my issue.

You can combine the two thus
SELECT CAST(CurrentDate AS DATETIME) + CAST(Time AS DATETIME) FROM Data


This will be a DATETIME value. So you might use a CTE to combine the values then do the compare
