Grouping By The Date Portion Of A Datetime Datatype
Jul 13, 2000
Hi,
I have a requirement to be able to select and group records by the date portion of a datetime field. ie ignore the time when grouping so that all records lodged on a particular day are seen together.
I have been able to do this by
- converting the datetime data to the number of days since a given date
- inserting this into a temporary table
- retrieving the the data from the temporary table
- convert the data back to a date using DATEPART to display dd/mm/yy
This then gives me the data grouped as required but seems to be a very difficult solution - Is there an easier way??
Thanks in advance

I have a SQL DB with a column called time_occurred that is formatted like ( 7/28/2004 7:10:30 AM ).
What I need to do is run a report based on just the month day and year portion. I am using the calendar control so mins, sec and milliseconds are not available nor do I really need them.
I am running the Query with this Stored Procedure
ALTER PROCEDURE dbo.Prodecure1
(
@WhereClause varchar(8000)
)
AS
-- Create a variable @SQLStatement
DECLARE @SQLStatement varchar(8000)
-- Enter the dynamic SQL statement into the variable @SQLStatement
SELECT @SQLStatement = 'SELECT column1, column2, etc...' +
@WhereClause
-- Execute the SQL statement
EXEC(@SQLStatement)
RETURN

I have below SQL, which should be order by posteddate ASC
SELECT AnnouncementID,[Subject],[Description],
CONVERT(nvarchar(10),PostedDate,101) AS PostedDate,
CONVERT(nvarchar(10),ExpiredDate,101) AS ExpiredDate,
CountryID,CreatedBy, CreatedDate, ModifiedBy, ModifiedDate
FROM Announcements a
WHERE isActive = 1
AND CountryID = 2
AND (GETDATE()>= PostedDate)
AND (GETDATE()<= ExpiredDate)
ORDER BY PostedDate ASC
But result is displaying as below, PostedDate datatype is datetime
01/01/2015
01/02/2015
12/28/2014
12/31/2014
Expected result is

For some reason, I recall having read that SQL Server 2005 would supporta datatype that represented date, but not time. (This would be usefulfor storing things like birthday, where you usually don't care about thetime of day). But I've got SQL Server 2005 installed, and there's nosuch datatype to be found.Is this something that might be released in a Service Pack, or is itjust not going to happen?

Hi,
We are migrating our database from DB2 8 to SQL Server 2005. We have date and time saperate columns in DB2. For example, Date_of_birth, Store_sun_open_time, Store_sun_close_time etc. For date we are using datetime. For time what datatype should we use in SQL Server?
Thanks

Need some quick help here.. The data I got from the text file use the "04/11/2007" date format and the StockDate in MS-SQL use the datetime datatype.
My understanding is that the "04/11/2007" will default to the 04/11/2007 12:00 am" format in MS-SQL.
So, when I use the sql query, how do search only for the date part of the data in MS-SQL and match it to the data from text file? I tried this SQL Query below.
--snip--
SELECT RawID FROM tblPurchaseRaw WHERE VIN = '" & sVin.ToString.Trim & "' AND StockDate = '" & dStockDate.ToString.Trim & "'
--snip--
That way, if I get a row then I know the data is there. If I don't get a row then I know the data is not there.
Bold: I get it now. It is all automatic as MS-SQL does it automatically...

I have a database which is centered around two date tables (approx. 5.5 million records each). We are finally making the big leap from SQL Server 2005 to 2012. The data is currently stored as datetime, and we are hoping to take advantage of the new date datatype, since the time component is not needed.
The first table has 13 different date columns. In testing on the 2012 server I have changed 3 columns so far, and have seen that changing the datatype to date is actually increasing the Index size and not affecting the data size. Only 3 of the columns are associated with indexes, and modifying a non-indexed column still increased the index size. I am running the Disk Usage by Table report to view the sizes.

Is there a way to strip off the time portion of a datetime datatype without changing the datatype?
I know I can convert it using CONVERT (NVARCHAR(10), dbo.tblPayments.PaymentDate, 101) but I need to keep it as a datetime datatype?

I have a PHP page where the user enters a date that represents the last day of a timesheet (ts_end) and the hours worked on that timesheet. That is then written into a table where the date is a datetime type. Because the user just enters a date, the time portion of the field is set to 00:00:00. In another place, I need to sum the columns for reports submitted between the beginning of a timesheet (ts_end -6 days) and the ts_end date.
The problem is that chartreviewed values entered on the ts_end date are getting lost because the time part of the ts_end field is 00:00:00 and the time part of the dateentered for the chartreviewed value is not. For instance using 2/4/2004 as the ts_end date looses the 192 charts.
Reporter activity chartsdateentered
2001576 20672 563 2004-01-29 13:55:51.000
2001576 20665 202 2004-02-02 19:54:57.000
2001576 20666 160 2004-02-03 22:48:11.000
2001576 20667 192 2004-02-04 19:41:51.000
I know I can revise the query to look for charts where the dateentered is less than dateadd(d,1,ts_end) and get the right values. It seems like there has to be a way though to tell sqlserver to ignore the time part of a datetime field when querying.
Anybody know what it is?
Thanks,
Ursus

I need to identify time spans where members identified as having a condition have NOT had any of 5 specified services in the past 12 months. I have a table (DiabStrata) that identifies time frames for which my data shows a member as having the condition, and I have 5 separate tables with the dates of the relevant services.
I can easily identify when a member hasn't had the service at all, or is lacking it at the start or end of the time frame for which they have the condition, but I'm hitting a wall on how to deal with gaps between the minimum and maximum identification dates.
Code Block
create table dbo.DiabStrata(memberid char(11),Strat tinyint, StratStart datetime, StratEnd datetime)
create table dbo.hba1c(memberid char(11),dos datetime)
insert DiabStrata(
select '1',1,'20060101','20070302'
union
select '1',1,'20070803','20080804'
union
select '2',1,'20020101','20080503')
insert hba1c(
select '1','20060301'
union
select '1','20070301'
union
select '2','20050101')
--Missed Service
Begin
select * into #eval from DiabStrata where strat=1
delete #eval
from #eval left join hba1c on #eval.memberid=hba1c.memberid where hba1c.memberid is null
--repeat for other indicators
update e
set stratstart=min(dos)
from #eval e join hba1c on e.memberid=hba1c.memberid
having min(dos)>stratstart
update e
set stratend=max(dos)+365
from #eval e join hba1c on e.memberid=hba1c.memberid
having max(dos)+365<stratend
delete from #eval where stratstart>stratend
--repeat for other indicators
Desired output is into DiabStrata with a strat of 2 for the time frame for which they have strat 1 but do not have all 5 services within the prior 365 days.
MID Strat StartStrat EndStrat
1 2 1/1/06 - 2/28/06
1 2 3/2/08 - 8/4/08
2 2 1/1/02 - 12/31/04
2 2 1/2/06 - 5/3/08

My goal is to take the btb-date and store it in the same table I loaded the seperate nodes to. Currently I am loading the req-header, req-property-address, and req-borrowers.
This date will be static in that it will remain the same for every record. My goal is to read it in and store it along with each record. Hope someone can give me some help.

I'm trying to translate this portion of VFP code into LINQ query:
select COUNT(ID) as conflicts
from dbo.max4sale where <<thisform.cWhere>>
AND Start_Time >= <<VFP2SQL(m.ltBegin + m.lnStartTime)>>
and Start_time <= <<VFP2SQL(m.ltEnd)>>
AND CONVERT(varchar(5),Start_Time,108) <= <<VFP2SQL(m.lcEndTime)>>
AND CONVERT(varchar(5),End_Time,108) >= <<VFP2SQL(m.lcStartTime)>>
<<m.lcDays>>
Here is my non-working attempt:
var startTime = new DateTime(1900, 1, 1, beginDateTime.Hour, beginDateTime.Minute, 0);
var endTime = new DateTime(1900, 1, 1, endDateTime.Hour, endDateTime.Minute, 0);
var daysOfWeek = dailyLimits.Where(dl => dl.Selected == true).Select(ds => ds.WeekDay).ToList();
if (daysOfWeek.Count() < 7) // not all days of the week selected
[Code] .......
First of all, I see a bug in my logic now as the first part of the query I need to do all the time and only the second part if the count < 7. But that's not my problem - I can not figure out how to make times comparison only using LINQ. Ideally I think I'd like to have cast(start_time as time) >= @p1 as a result to be executed by LINQ.
BTW, I am only getting the error in run-time that Parse can not be interpreted. So, I need to figure out another way of making LINQ recognize my intent of checking time portion of the date only.

Hello,
I am trying to group the date by minutes. The date is in
datetime format. My problem is when grouping the seconds
throws me off.
eg. id date
1 03-02-1999 10:23:12.000
2 03-02-1999 10:23:11.000
what I want is when I run count(date) and group by
date the above example should give me 2. In short it
should group 1 & 2 because I want to ignore the seconds.
How can I do that. Everything else is working except
this is kicking my brains. Any and all help aprreciated.
It is also sorts urgent.
Thanks in advance.

Hi all.
I'm using foxpro and I'm completely new to SQL. I'm trying to create a database into which I need to enter a time field. I've read around on the net that the only way to do this is using a datetime datatype but I can't find anywhere that explains the format I use to INSERT INTO my tables.
Anyone help?
*EDIT* I actually just want to enter the time and not the date and the time, I have read it is possible to do this using a convert but I'm happy enough to have the date and the time as I don't want to overcomplicate anything at this stage.

Are we allowed to do a LIKE datetime in SQL queries?
The records data looks like so:
9/21/2000 10:30:40 AM
But I want to see model requests by an entire day ala:
Select * From ModelRequests Where RequestDateTime Like '9/21/2000%'
But I do know get any records returned.

Hello!
Here's the puzzle I'm trying to solve.
I have 2 columns (CreatedDate and StatusDate) in the table both of datetime datatype.
When I run query
select * from sale
where Statusadate = "11/30/2001" it returns rows back.
When I do the same but for CreatedDate column
select * from sale
where CreatedDate="11/30/2001" it returns zero rows back even if there are CreatedDates = "11/30/2001".
I don't understand why it works for one column and doesn't work for another one.
The example of CreatedDate value is "2001-11-30 10:10:33.000"
Thank you,
Lena

hi everybody,
i'm trying to calculate the 'SUM' of time spent in hrs. n min. How can i do this using SQL Server?
What i mean is, i've a column 'TIME_SPENT' that has 'datetime' datatype. This column saves time spent for an activity in format 'hh:mm'. Suppose a user spends 45min for activity 'A' and say 1hr 25 min for activity 'B' then i want to calculate the 'SUM' of 'TIME_SPENT' for the user which should appear as 'Total time spent =2:10'
Can somebody pls help me with this?
Thnx in advance.
