Hi,

Where startdate >= yesterday 4:30 am and startdate <=today 4:29 am
There is also a report I need to generate for Monday 4:30a.m to Saturday 4:30 am every week.
Thanks for all the help in advance!

It 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.

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

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 YourTable

Where YourDate >= dateadd(minute, 990, dateadd(day, datediff(day, 0, getdate()), 0))

And YourDate < dateadd(minute, 990, dateadd(day, datediff(day, 0, getdate()) - 1, 0))

select

*

from

MyTable

where

-- 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')

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 @start_date and @end_date 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 @start_date and @end_date 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

I usually create two datasets:

1. StartDate

SELECT CAST((CONVERT(varchar(10), GETDATE()-9, 101)) AS DATETIME) AS StartDate

2. EndDate

SELECT CAST((CONVERT(varchar(10), GETDATE()-2, 101) + ' 23:59:59') AS DATETIME) AS EndDate

Then set the parameters @StartDate and @EndDate equal to the values of these two datasets.

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.

Queries for a date range should normally be in this form:

where MyDatetimeColumn >= @StartDatetime and MyDatetimeColumn < @EndDatetime

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'.
