Question

I am trying to grab orders between certain dates using the BETWEEN operator in SQL.

My date formats are in dd/mm/yyyy format.

ord_fdate is the from date: Currently 01/03/2012
ord_tdate is the to date: Currently 07/03/2012

I thought this would return all orders from 01/03/2012 (including 01/03/2012) to 07/03/2012 (including 07/03/2012).

However, it does not get orders with dates 07/03/2012

My query below; i have also included the debug output of the query;

<cfset ord_fdate = DateFormat(ord_fdate, "dd/mm/yyyy")>
<cfset ord_tdate = DateFormat(ord_tdate, "dd/mm/yyyy")>
<cfquery name="getOrders" datasource="#application.dsn#">
SELECT 
  dbo.tbl_orders.uid_orders,
  dbo.tbl_orders.dte_order_stamp

FROM
  dbo.tbl_orders
  WHERE dbo.tbl_orders.uid_order_webid=<cfqueryparam cfsqltype="cf_sql_integer" value="#session.webid#">
  AND bit_order_archive=<cfqueryparam cfsqltype="cf_sql_bit" value="no">
  AND txt_order_status=<cfqueryparam cfsqltype="cf_sql_varchar" value="Awaiting Dispatch">
  AND dte_order_stamp BETWEEN <cfqueryparam cfsqltype="cf_sql_date" value="#createODBCDate(ord_fdate)#"> AND <cfqueryparam cfsqltype="cf_sql_date" value="#createODBCDate(ord_tdate)#">
  ORDER BY dte_order_stamp DESC
</cfquery>

Debug;

WHERE (dbo.tbl_orders.uid_order_webid=?
  AND bit_order_archive=?
  AND txt_order_status=?
  AND dte_order_stamp BETWEEN ? AND ?)


  ORDER BY dte_order_stamp DESC
Query Parameter Value(s) -
Parameter #1(cf_sql_integer) = 1
Parameter #2(cf_sql_bit) = NO
Parameter #3(cf_sql_varchar) = Awaiting Dispatch
Parameter #4(cf_sql_date) = {ts '2012-03-01 00:00:00'}
Parameter #5(cf_sql_date) = {ts '2012-03-07 00:00:00'}

Not sure why it is not working.

Database is SQL 2008

Any ideas?

Answer 1

Does your date field include time? If so, between will only give you values >= the first date, and <= the second date at midnight. Any date that includes a time past midnight will be ignored.

I usually do something like this when dealing with dates:

If I want everything from 1/1/2012 I set up the start date as 1/1/2012, and the end date as one day later (at midnight)…

declare @StartDate datetime = '01/01/2012'
declare @EndDate datetime = '01/02/2012'

Then select the values like this:

select * from your_table where date >= @StartDate and date < @EndDate

When checking against the end date I want anything with a value less than the end date. This will include values such as 1/1/2012 12:30, 1/1/2012 23:20, etc.
