Hi,
I have such a scenario:
- two tables with record containing car vehicle number, datetime of message and other data like weight ect.
- first table contains only two messages for one car per one day
- second has many messages for one car for one day
I would like to get a list of messages from first table but joined with the nearest (previous) record for the same car from second table.
Thanks,

How would I match datetimes in records structured as follows:
Code:
Record1 AccountNo StartDateTime EndDateTime
1 1234 4/30/2012 8:00 AM NULL
2 1234 NULL 5/15/2012 8:00 AM
Desired Result:
Code:
AccountNo StartDateTime EndDateTime
1234 4/30/2012 8:00 AM 5/15/2012 8:00 AM
Of course there are multiple accounts, about 2100 in this case but they very by time periods, and multiple start and stop dates for an account. I need to get the start times and match them w/ the nearest end times but AFTER the value of the start time. Nearest end times must be forced to correspond to the nearest start time but there are some start times w/o end times and end times w/o start times due to user data entry errors. I need a solution that handles this. It is ok w/ the customer to make the assumption of nearest times supposedly going together so they can show the users the errors. I am on SQL Server 2008 R2.
Is there a way that I can do this at the table level to automatically handle the rounding of seconds, etc. down to the minute automatically without having to use a trigger?
Here is a very basic example of what I am trying to do:
--example: '09-22-2007 15:07:18.850' this is the value inserted into the table by the code
select getdate()
--example: '2007-09-22 15:07:00.000' this is the value I want to store in the table
select dateadd(mi, datediff(mi, 0, getdate()), 0)
I am trying to join two tables and the datetime fields need to be part of the join. They contain times in the fields too. I just need them to join on the date part though. Is there maybe a way to just return the mm/dd/yyyy format and join on that? Any and all help is appreciated.
Thanks,
Chris
Table A Table BBOL# B_BOL#Chargeback#Hi All,I have been struggling with this for the past few months. I have twotables that I'm inner joining on BOL#=B_BOL#. This works fine. Now forthe problem....When there are chargeback# fields associated with B_BOL#they aren't being captured as additional records. None of my tableshave primary keys because at any given time any field can contain a"null" value, so I am unable to assign a foreign key, I think. How canI attach the subsequent records to the main record to bring back theadditonal data? Please help!!!

I've got a table of categories. I also have a table of items each assigned to one of those categories. Each item has many image urls associated with it. I'd like to get a list of all of the categories and one image (I don't care which) for each category. Here's the tables:

Can I do this in one query? Thanks
Hey :)I'm facing a lot of troubles trying to create a new pause/break-system. Right now i'm building up the query that counts how many records that is inside 2 fields. Let me first show you my table:
ID (int) | stamp_start (Type: DateTime) | stamp_end (Type: DateTime) | Username (varchar)0 | 17-03-07 12:00:00 | 17-03-07 12:30:00 | Hovgaard
The client will enter a start time and a end time and this query should then count how many records that are inside this periode of time.
Example: The client enter starttime: 12:05 and endtime: 12:35.The query shall then return 1 record found. The same thing if the user enters 12:20 and 12:50.My current query looks like this:SELECT COUNT(ID) AS Expr1 FROM table WHERE (start_stamp <= @pausetime_start) AND (end_stamp >= @pausetime_end)But this will only count if I enter the exact same times as the one inside the table.Any ideas how I can figure this out?Thanks for your time so far :)/Jonas Hovgaard - Denmark
I would like to know if it's possible to return a single record by joining the tables below. [Persons]

4 12
[PersonNames] - PersonID JOINS Persons.PersonID

=============== ============== ======================= ===================
1 1 Samantha Brown 5
1 2 Samantha Green 10
2 3 Richard T 10
3 4 Riko T 0
4 5 Sammie H 0

[PersonAllNames] - JOINS [PersonNames.NameID] ON [AltNames.AltNameID]
NameID [int] | AltNameID [int]
============= ================
1 1
4 1
3 2
This is ideally what I'd like to have returned: PersonID | PageViewed | MostPopularName | NameSearch
========= ============ ================= =================
1 10 Samantha Green Samantha Brown, Samantha Green, Sam, Samantha, Sammie, Sammy
2 5 Richard T Richard T
3 2 Riko T Riko T, Riko, Rico
4 12 Sammie H Sammie H, Sam, Samantha, Sammie, Sammy
[MostPopularName] is [PersonNames.PopularVotes DESC].[NameSearch] combines all records from [PersonNames.PersonName] and [AltNames.AltNames].
The purpose for this is that I'd like to cache the results table so that all searches can just perform a lookup against the NameSearch field.
Any help would be greatly appreciated.
Thanks, Pete.
I have tried joining several tables and the result displays duplicate rows of virtually every line/row. I have tried using distinct but this didn't work. I know it could because there's several columns from some of the tables named the same.
select purchaseorders.traderid,
suppliers.name
stockbatches.partid,
allpartmaster.partdesc,
allpartmaster.prodgroup,

I have a query question.
Consider a table with the following structure:
RecordID (PK - int) - RecordDate (DateTime)
I need to find all records that fall within a 7 day period slot based on the first RecordDate of a specific slot.
Example, consider the following records:
RecordID - RecordDate
1 - 2015-04-01 14:00
2 - 2015-04-03 15:00
3 - 2015-04-03 16:05
4 - 2015-04-03 19:23
5 - 2015-04-06 09:15
6 - 2015-04-06 11:30
7 - 2015-04-07 12:00
8 - 2015-04-09 15:15
The result of the query I'd like should look something like this
1
2
5
7
8
So basically I'd like to leave record 3 and 4 out because they fall within 24 hours of record 2 and I'd like to leave record 6 out because it falls within 24 hours of record 5.I'd tried working with a CTE and set a dateadd(d, 1, recorddate), join it on itself and use a between From / To filter on the join but that didn't work. I don't think NTILE will work with this?

Hi, I'm making a birthdays database where I want to list everyone in it ordered by the firstcoming birthdays according to the current date.
I have all the birthday records stored in a table called bursdager and the person name is stored in the navn column and the persons birthday date is stored in the dato column.
I'm having some problems, currently I have this statement:
Code:
DECLARE @tbl TABLE (navn VARCHAR(60), dato DATETIME)
INSERT INTO @tbl
SELECT navn, dato FROM bursdager
WHERE DATEPART(month, dato) >= DATEPART(month, getdate())
ORDER BY DATEPART(month, dato), DATEPART(day, dato)
INSERT INTO @tbl -- those are the one who allready have had birthday this year
SELECT navn, dato FROM bursdager
WHERE DATEPART(month, dato) < DATEPART(month, getdate())
ORDER BY DATEPART(month, dato), DATEPART(day, dato)
SELECT * FROM @tbl
It works *allmost* as it should-- except, it still lists the last persons who had birthday first, even the days after their birthday if the month is still the same.
I thought about adding an additional check:
Code:
AND DATEPART(day, dato) >= DATEPART(day, getdate())
in the WHERE clause of the SELECT statement but that won't be correct either because it then just lists everyone based on whether the day number the person was born is higher or less than the day number of the current date.
Anyone have any suggestions? Is there an easier way to do it?

OK, this is the scenario. I have a database with many columns ( each a mean value and a standard deviation, and with it a set of coordinates that i want to retrieve ).
Then i have a value that i want to query with the database, by comparing it with the mean and its standard deviation, and it should return a few sets (lets say 2) of coordinates whereby the the value of the mean is closet to the one in the database, in order of nearest value. How should i do it, since i am not using the exact value of the mean in the database?
I know its a bit confusing the way i wrote, but anyone understand wat i am trying to say and can help, i am very grateful. I had googled around for answers but cannot find. Thanks.
I have a date (my birthday). I would like to find the closest birthdays to mine, both before and after my birthday. I would like to list the people in my database who are the closest age to me, but in that order. So sorting my table by age and taking a row below and above my birthday is not going to work. This is because the three people below me may all have their birthday the next day, while those above me may have theirs years before mine.
Birthdays sorted by date:
05/10/1979 jim
12/01/1980 bob

10/05/1983 larry

Given a date, what module was each equipment item in on that date?How do I get the date of the nearest previous event from a list like this? I got a query from one of the post in this Forum only using Cross Apply to find the nearest record from the above table based on Date i.e.
SELECT outerT.*

CROSS APPLY

SELECT TOP 1
equipment_id

AND innerT.equipment_id = outerT.equipment_id
ORDER BY change_date DESC
) AS applicable_records
WHERE applicable_records.change_date = outerT.change_date

The value in the date_t column is 2007-07-09 22:10:11 000.The milliseconds value is always 000 only.I need the millisecond values also in date_t column.
Is there any conversion needed for millisecond values?
