RE: Getting datepart to work for query

Queries for a date range should normally be in this form:[code]where MyDatetimeColumn >= @StartDatetime and MyDatetimeColumn < @EndDatetime[/code]In other words greater than or equal to the first point in time that we know that we want, and less than the first point in time that we don't want.There is never any guarantee that the precision of time intervals will stay the same in future releases, so it is unrealistic to code end time as "2009-06-29 23:59:59.997", even if this is the last possible moment that we want to select with the current version of SQL Server. Just code it as less than '2009-06-30'.

[quote][b]Mark Eytcheson (6/29/2009)[/b][hr]I usually create two datasets:1. StartDateSELECT CAST((CONVERT(varchar(10), GETDATE()-9, 101)) AS DATETIME) AS StartDate2. EndDateSELECT CAST((CONVERT(varchar(10), GETDATE()-2, 101) + ' 23:59:59') AS DATETIME) AS EndDateThen set the parameters @StartDate and @EndDate equal to the values of these two datasets.[/quote]SELECT CAST((CONVERT(varchar(10), GETDATE()-2, 101) + ' 23:59:59') AS DATETIME) AS EndDate --> This will miss any records with a datetime value > [Date] 23:59:59.000 and [Date + 1] 00:00:00.000.

Thanks so much for helping out. I will use the syntax posted in the solution.Here is the part that I had needed help with in my where clause...(where (timesheet.wcstart between [b]@start_date and @end_date [/b]and timesheet.wcfinish is null))INSERT INTO #timesheet SELECT emp.firstname + ' ' + emp.surname, mo.monumber, inv.customer_part_num, inv.description, t.opno, routing.description,workcenter.name, Case When timesheet.wcstart < @start_date then @start_date Else timesheet.wcstart End, timesheet.wcfinish, ISNULL(workcenter.machine,'X'), '', TSNo FROM mfg_timesheet t Left outer join cubs..mfg_mo_routing routing On routing.companyid = timesheet.companyid and routing.mo_key = timesheet.mo_key and routing.opno = timesheet.opno Left outer join cubs..mfg_workcenter workcenter On workcenter.wcno = timesheet.wcno and workcenter.companyid = timesheet.companyid, mfg_mo mo, inv_item inv,mfg_employee emp,slsord sls where (timesheet.wcstart between [b]@start_date and @end_date [/b]and timesheet.wcfinish is null) and mo.mo_key = timesheet.mo_key and emp.employeeid = timesheet.employeeid and mo.companyid = inv.company_id and mo.stocknumber = inv.stock_number and timesheet.companyid = 1 and workcenter.machine IN ('W') And TSNo NOT IN (SELECT TsNo FROM mfg_timesheetAdj) and sls.company_id = mo.companyid and sls.slsord_number = mo.slsord_number

[code]select *from MyTablewhere -- Greater than or equal to yesterday at 04:30 MyDate >= dateadd(day,datediff(day,0,getdate())-1,'04:30') and -- Less than today at 04:30 MyDate < dateadd(day,datediff(day,0,getdate()) ,'04:30')[/code]

Here are a few things for you to look at:Select dateadd(minute, 990, dateadd(day, datediff(day, 0, getdate()), 0)) ,dateadd(minute, 990, dateadd(day, datediff(day, 0, getdate()) - 1, 0))Now, with the above you could do something like:Select {columns}From YourTableWhere YourDate >= dateadd(minute, 990, dateadd(day, datediff(day, 0, getdate()), 0))And YourDate < dateadd(minute, 990, dateadd(day, datediff(day, 0, getdate()) - 1, 0))

shree dhavaleIt would help those who will be attempting to help you if you provided the table structure, sample data and the T-SQL statement that you have attempted to utilize. All this per the article whose link is in my signature block.
