Question

Hi guys i have a table expenses with multiple records.

expenseID       ratename         description            workcompleted

51699           Base Rate        SNL Financial inquiry  08/09/2011
51699           Base Rate        SNL Financial inquiry  08/19/2011
51699           Base Rate        SNL Financial inquiry  08/09/2012
51699           Base Rate        SNL Financial inquiry  08/19/2012

But when i search record only for year 2012 but it return record for both the year(2011, 2012). But I need my record comes by year only i.e.

expected results:

51699   Base Rate   SNL Financial inquiry   08/09/2012
51699   Base Rate   SNL Financial inquiry   08/19/2012

Please see my query :

select expenseid,ratename,description,workcompleted from EXPENSES 
where workcompleted >= '08/08/2012' and workcompleted <= '08/19/2012'

I also try this by using between query but it doesn’t work. If any body have an idea kindly share to me.

Answer 1

You’re almost certainly using the wrong data type. Your column “work_completed” should be of type date. It’s almost certainly char or varchar. Your best bet is to change the data type.

If you can’t do that, you can create a view that mirrors the table, but casts the “work_completed” column to a date type. Querying a date range against such a view should work correctly.

If you can’t create views, you can change your WHERE clause to do the cast. In standard SQL, it would look like

WHERE CAST(workcompleted AS DATE) >= '2012-08-08' 
  AND CAST(workcompleted AS DATE) <= '2012-08-19'

I know SQL Server supports CAST(), but you’ll probably have to go with your original format for the dates (like ’08/08/2012′).

Expect a performance hit if you do that. SQL Server will have to do two type casts on every row.
