Help - Finding The Newest Date Without Using Max()
Sep 18, 2006
Hi,
Can anyone help please?
select notefield, modifiedon
FROM Table1
WHERE id = '100426' and
(statusfield like '%criteria1%' OR
statusfield like '%criteria2%')
Produces a list of records based upon the criteria. I would like to be
able to only show the newest dated record, from the modifiedon field.
I've tried max(modified) on, but as I am using an aggregate function in
the query I have to use GROUP BY, which notefield does not like as this
is a ntext field.
(I get:
Server: Msg 306, Level 16, State 2, Line 1
The text, ntext, and image data types cannot be compared or sorted,
except when using IS NULL or LIKE operator.
)
Any ideas please?

Hey all,
I just discovered this cool forum. I am fairly new to T-SQL, so please bear with me.
Here is my problem. I am trying to return 1 record for each distinct MachineName, based on the most current CreateTime.
I have tried a bunch of different things, but the follwing query seems to get me close, except for all of the records, per MachineName, that aren't the newest CreateTime. Can anyone offer a suggestion I may be missing?
Here is my query:
SELECT
rcv.Name AS MachineName, r.CreateTime, rpv.Path + rpv.Name AS ResourcePool
FROM
dbo.Result_View AS r WITH (NOLOCK) INNER JOIN
dbo.ResourceConfiguration_View AS rcv WITH (NOLOCK) ON r.ResourceConfigurationId = rcv.Id INNER JOIN
dbo.Resource_View AS rv WITH (NOLOCK) ON rcv.ResourceId = rv.Id INNER JOIN
dbo.ResourcePool_View AS rpv WITH (NOLOCK) ON rv.ResourcePoolId = rpv.Id
WHERE
(rpv.Name NOT LIKE 'Archive')
AND
(r.CreateTime > '2/1/2008')
AND
(r.CreateTime = (SELECT TOP (1) r.CreateTime FROM dbo.Result_View))
ORDER BY MachineName
I have added the '2/1/2008' filter, so as not to hammer the DB too hard. It goes back for some time.
Thanks in advance,
Allen

I am trying to find a beginning date from multiple date ranges, for example:
RowNumberidBegin dtEnd Dt
107933192014-09-022015-06-30
207933192013-09-032014-09-01
307933192012-09-042013-09-02
407933192011-09-062012-09-03
For this id: 0793319, my beginning date is 2011-09-06
108203492014-09-022015-06-30
208203492013-09-032014-09-01
308203492012-09-042013-09-02
408203492011-12-122012-07-03--not a continuous date range
For this id: 0793319, my beginning date is 2012-09-04
108203492014-09-022015-06-30
For this id: 0820349, my beginning date is 2014-09-02
To find continuous date, you look at the beginning date in row 1 and end date in row 2, then if no break in dates, row 2 beginning date to row 3 end date, if no break continue until last date There could multiple dates up to 12 which I have to check for "no break" in dates, if break, display beginning date of last continuous date.

the requirements are to return person ID with the most recent leaving date from a scheduled dept, who has previously arrived at an unscheduled dept within 7 days, but just now my query shows all the previous leaving dates within 7 days of that unscheduled dept arrival, I only want the last leaving date before the arrival at the unscheduled dept:
So for instance looking at a copy of one person's date below I have:
PersonID Last Dept Arrival Date To Last Dept Leaving Date From Last Dept Next Arrival Date to Unscheduled Dept
======== ================= ========================= =========================== =====================================
0106573268Dept 5 2013-03-01 2013-03-03 2013-03-05
0106573268Dept 6 2013-02-27 2013-02-27 2013-03-05
0106573268dept 2 2013-02-26 2013-02-26 2013-03-05
In the data above I only want to return the first row, which is the most recent leaving date before arrival at an unscheduled dept.
My query is much the same as before except my inline view is looking at the data for last scheduled leaves from depts in my inline view and also the outer query returning all arrivals to the unscheduled dept:
SELECT b.personID
,b.dept AS "Last leaving dept"
,b.arrival_Date as "arrival Date To Last dept"
,b.leaving_Date AS "leaving Date From Last dept",
a.[arrival Date] as "Next arrival Date to AREA_GH"
FROM Unscheduled_Arrival a INNER JOIN (SELECT *
FROM scheduled_Leaves
where [leaving date] is not null) b
ON a.Person_ID = b.Person_ID
[code]....

Hi;
We received a Payment from a customer on '10/10/2007 10:30:00'. i am trying to calculate the commission we would receive from that payment. the commission rate can be edited. so i have to find what the commission rate was when that payment was received.
I have a CommisionAudit table that tracks changes in commission rate with the following values.
ID | Commission Change | UpdatedOn
----------------------------------------------
1 | Change from 20->25 | 03/07/2007 09:00:00
----------------------------------------------
2 | Change from 25->35 | 10/09/2007 17:00:00
----------------------------------------------
3 | Change from 35->20 | 01/10/2007 16:00:00
----------------------------------------------
4 | Change from 20->26 | 11/10/2007 10:00:00
----------------------------------------------
with this payment, as the commission rate had been changed on 01/10/2007 it would obviously be 20%(ID 3). But I need to write sql to cover all eventualities i.e. Before the first and after the last. any help would be most welcome.

I have a table containing several date fields in which certain events happened, and I need to be able to find the expiration date for renewal. The expiration dates are at the end of the 6th, 12th, or 24th month after the event occurred, depending on the event.
Is there a way to return in a query the last day of month x following a date field? For instance, if the date '3/12/2006' is stored in the field for a 12-month expiration, I need to return '3/31/2007'.
Any ideas?

I wanted to determine the date of the last Saturday with respect to the current date so that I could create a temp table with date ranges numbered 1-4 e.g. up to that date, post link below: URL....I now want to make this function that any time I pass it a day name (mon-sun) it will calculate the date of the previous (mon-sun) with respect to the current day. This date will then be the last date in my range.
So for example I run the function and pass it 'Friday' then I want last date in my range to be the 25th of July (today being Friday so need last Friday), I pass it Thursday I want it to give me the 31st of July etc. I need last date of that date but if I call Friday and today is Friday then need last friday; I think this is the trickier part of it.
This calculation I would image would need to use a combination of datediff dateadd etc. but really don't know how to do this dynamically.Currently I have a function that I pass the last date for the date range I want for my weeks range, I also give it the numbere of weeks I want in my range and also pass the date from the query that I want to know what week range it is in.
ALTER FUNCTION [dbo].[daterangeweeknumber]
(
-- Add the parameters for the function here
@refDate datetime,
@Weeks INT,
@lastdate datetime
]code]....
But now I want just to be able to pass it the day name - in this instance would be 'Wednesday' and want it to return date ranges with last date as Wed the 30th of July. Reason I want to use day name is that people will be running these reports on a certain day - for instance on Wednesday and last day to be Monday - and this will mean they do not have to keep changing the date in the call to function.

Is there a way to find out when the last modification or change to data in a table occured ? How about the last change of a view ?
We'd like to be able to extract data to another table based on a view. Then, at a later date, check to see if the first table or view has changed since the last extract. If not, then we don't need to re-extract the data, we know it hasn't changed.

I know I am missing something basic, here.
I have a date field in a table. The field is 'allowed Nulls'. When a certain thing happens in the program, the date is filled in.
At various times, I need to do a query to find all the rows that have no dates entered.
What do I use in my where clause? SQL server does not like 'where date = null.'
Thanks,

I have a group of date ranges and wanted to identify all of the date gaps within the ranges, outputting the dates as another date range dataset.
Example dataset SQL below:
CREATE TABLE #test (daterow int identity, obj_id int, datestart DATETIME, dateend DATETIME)
INSERT INTO #test
SELECT 1, '20130428', '20130523'
UNION
SELECT 1, '20130526', '20130823'
[Code] ....
I would expect a dataset to be returned consisting of:
1, 24/05/2013, 25/05/2013
1, 24/08/2013, 25/08/2013
2, 16/05/2013, 24/05/2013
I have found a lot of examples of problems where I have just a single date column, and then I find the gaps in between that, but I'm having difficulty finding examples where it works with start and end date columns...

In my query I have a date field and using that date field I want to pass the date to a function, or whatever is most appropriate, then compare that date with a range of the last 4 weeks, which will be numbered 1-4, 1 being earliest and 4 being latest, and then return the week number.
I've determined I need some sort of look up but will need to be dynamic - thinking maybe a temp table, first using the date the report is run on and counting 28 days back from the most recent last saturday then setting number to 1 for first 7 days then 2 for next 7 days etc.

I have a table of employee assignments that I'm narrowing down to a specific group. Employees have multiple assignments (job positions essentially) and each has start and end dates. I need to identify the date range(s) that are covered by the assignments in my data set. Here's an example of data for one person ID. NULL in the end_date just means it is an active assignment. The pos_id column isn't necessary, but it define the data I'm looking at. The end result won't use it.
IDCOMPANYPOS_IDSTART_DATEEND_DATE
999119/2/20119/9/2012
999119/10/20129/10/2012
999119/11/20129/11/2012
999119/12/20126/2/2013
999116/3/20136/30/2013
[Code] ....
In this case I want results to say that ID 999 has a range from 9/2/2011 to NULL. There are no gaps in the date range. Or to say it differently, there's always an assignment starting the next day after an end_date. Or an assignment that overlaps the end and beginning of another assignment.
Here's another example where there is a gap in the ranges.
IDCOMPANYPOS_IDSTART_DATEEND_DATE
333112011-09-022012-08-31
333112012-09-012012-09-10
333112012-09-112012-09-11
333112012-09-122013-01-06
333112013-09-01NULL
There would be 2 result rows for this with a range from 2011-09-02 to 2013-01-06 and a second for 2013-09-01 to NULL.
The end result would be to have a row per date range for every ID. I've written a script that will find the ranges but it is a painful RBAR solution that takes forever to run. Every different path I've gone down trying to solve it ends in evaluating row by row grouped by the Person ID. The assignments are not always continuous, so I can't use a MAX and MIN and there may be 1 or more gaps in the dates to account for.

I'm trying to find if any part of a date range in my table between orig_start_rent and stop_rent falls within a period I specify in two variables: startPeriod and endPeriod
For example if I specify 2013-11-01 as startPeriod and 2013-11-30 as endPeriod, then if any part of the date range between orig_start_rent and stop_rent(stop-rent can be null if hire is open) falls within that period, I want that to be picked up and assigned the value of 1 in my case statement for OnHire. My code is not picking everything up however - using the example above, a record with orig_start_rent of 2013-05-23 and stop_rent of 2013-11-18 is being assigned 0 when it should be 1. My code here:
declare @startPeriod as smalldatetime
declare @endPeriod as smalldatetime
set @startPeriod = '2013-11-01'
set @endPeriod = '2013-11-30';
select dticket, orig_start_rent, stop_rent, case when orig_start_rent >= @startPeriod and orig_start_rent <= @endPeriod then 1 when orig_start_rent < @endPeriod and stop_rent is null then 1 else 0 end [OnHire] from deltickitem

Hi everyone -
I am building from the Time Tracker Start Kit, trying to get a better feel for how MS thinks we should do things.
In my editing, I have built a new Stored Procedure, trying to pull the newest entries for a specified person.
I have the following that will return all entries for a specific person, sorted by date, newest first:
SELECT
EntryLogID, TT_EntryLog.Description, Duration, EntryDate, TT_EntryLog.ProjectID AS ProjectID,
TT_EntryLog.CategoryID AS CategoryID, TT_Categories.Abbreviation AS CategoryName, TT_Projects.Name AS ProjectName,
ManagerUserID, TT_Categories.Abbreviation AS CatShortName
FROM
TT_EntryLog
INNER JOIN
TT_Categories
ON
TT_EntryLog.CategoryID = TT_Categories.CategoryID
INNER JOIN
TT_Projects
ON
TT_EntryLog.ProjectID = TT_Projects.ProjectID
WHERE
UserID = @UserID
ORDER BY
EntryDate Desc
This will return something like:
EntryLogId Description Duration EntryDate ProjectID CategoryID CategoryName ProjectName ManagerUserID CatShortName

The query Ihave set up isSELECT TOP 100 PERCENT dbo.vwEvents.EventName,dbo.luSessionAll.SessionName, dbo.luOuting.OutingNumber,dbo.luVehicle.VehicleName, dbo.luOuting.OutingID,dbo.tblOutings.OutingStartTime,dbo.tblSessions.Ses sionDate,dbo.tblSessions.SessionStartTimeFROM dbo.vwSessions INNER JOIN dbo.vwEvents ONdbo.vwSessions.Event = dbo.vwEvents.EventIDINNER JOINdbo.luSessionAll ON dbo.vwEvents.EventID =dbo.luSessionAll.Event INNER JOINdbo.luOuting ON dbo.luSessionAll.SessionID =dbo.luOuting.SessionID INNER JOINdbo.luVehicle ON dbo.luSessionAll.Vehicle =dbo.luVehicle.VehicleID INNER JOINdbo.tblOutings ON dbo.luOuting.OutingID =dbo.tblOutings.OutingID INNER JOINdbo.tblSessions ON dbo.tblOutings.[Session] =dbo.tblSessions.SessionIDGROUP BY dbo.vwEvents.EventName, dbo.luSessionAll.SessionName,dbo.luOuting.OutingNumber, dbo.luVehicle.VehicleName,dbo.luOuting.OutingID, dbo.tblOutings.OutingStartTime,dbo.tblSessions.SessionStartTime, dbo.tblSessions.SessionDateORDER BY dbo.luVehicle.VehicleName, dbo.tblSessions.SessionDate,dbo.tblSessions.SessionStartTime, dbo.tblOutings.OutingStartTimethis returns all the outings. I would like the outing that has, inorder of importance, the latest session date, latest session time andlatest outing start time. Outing start time can sometimes be <<Null>>but the other two always have values. How would I go about doing this?thanks in advance for any help

I have just started to use Integration Services Catalog with SQL Server Agent. After I deploy a new version of the project the any Server Agent job that uses any of dstx still uses the old one. How do I fix this?

I dont know how to get the newest input for each user from one single table.
Should be a very simple task but i cant work it out.
The table looks like this:
ID (A_I), userID, ip, date(timestamp)
Here is a SQL Fiddle Link with some data also: [URL] ....
I have tried a lot querys like this one:
SELECT userID, ip FROM userips GROUP BY userID ORDER BY ID DESC
But this one does not give me the latest ip which was entered by a user.

Hello everybody,-------------------------------------------------CREATE TABLE [T1] ([IDX] [numeric](18, 0) IDENTITY (1, 1) NOT NULL ,[DateEvt] [datetime] NOT NULL,[Value] [varchar] (10) NOT NULL ,[DataX] [varchar] (10) NULL ,CONSTRAINT [PK_T1] PRIMARY KEY CLUSTERED([IDX]) WITH FILLFACTOR = 90 ON [PRIMARY]) ON [PRIMARY]GOinsert into T1 (DateEvt,Value, DataX) values('2004.10.10 10:00:00','0000000001', 'AAAAAAAAAA')insert into T1 (DateEvt,Value, DataX) values('2004.10.10 10:00:01','0000000002', 'AAAAAAAAAA')insert into T1 (DateEvt,Value, DataX) values('2004.10.10 10:00:02','0000000003', 'AAAAAAAAAA')insert into T1 (DateEvt,Value, DataX) values('2004.10.10 10:01:00','0000000001', 'BBBBBBBBBB')insert into T1 (DateEvt,Value, DataX) values('2004.10.10 10:02:00','0000000001', 'CCCCCCCCCC')insert into T1 (DateEvt,Value, DataX) values('2004.10.10 10:03:00','0000000001', 'DDDDDDDDDD')GO-------------------------------------------------and the question is:In which fastes and best for the preformance way, get the last IDX ofspecified Value.I could do this like this:-------------------------------------------------declare @nIDX numericdeclare @sValue varchar(10)select top 1 @nIDX = IDX from T1where Value = @sValueorder by DateEVT desc-------------------------------------------------But I know, this is not fast (even if I have index on DateEVT field),and I'm quite sure, that there is better way to get this IDX.Anyway, this table can be big (like 20 milions records).I could take the max of IDX, but is it a sure way?Any help? Thanks in advanceMatik

I have the following Table:DataIDuserIDTimeStampI need to create a query that selects the "newest" records for all distinct users. I'm hoping to get this done in one query. I know I could write multiple queries to find all distinct users, and then the newest records based on that... and so on... but I'm not sure that's the most efficient. I have the following so far, but is it the most efficient (I have indexing on most of my columns)? SELECT DATA.DataID, DATA.UserID, UN.vchName, UN.vchImage, U.vchFirstName + ' ' + U.vchLastName AS 'FullName' FROM [tblData] DATA INNER JOIN [tblUnits] UN ON DATA.UserID = Un.UserID INNER JOIN [tblusers] U ON U.UserID = UN.UserID WHERE GPS.intGPSDataID IN (SELECT MAX([tbLData].DataID) FROM [tbLData] GROUP BY [tbLData].UserID)

Ok here's a big one.
First I'm a big NEWBIE, so it'd be great if you can provide a little explanation as to how this should be done...
Here's what I want to do, but have no idea how to approach it.
I have a table with Quotes (table Quote) in them (for a Sale's Team). Each has a quote number (qtQN) and this number is sequencial but sometimes revised where a letter is added at the end. Like so:
qtQN__________Date
---------------------------
111q0001--------02/01/04
111q0002--------02/02/04
111q0002A------02/03/04
111q0002B -----02/04/04
222q0005--------01/15/04
etc... ------------- etc...
The first 3 digit are company codes and pretty unimportant to this problem. As you can see, 111q0002 has three versions. A, B, and no letter. The most up to date is B. So in this list I want to list only the most up to date quotes. So the resulting list would be:
111q0001
111q0002B
222q0005
Get it? Good, cuz I have no idea how to query that... any help at all is appreciated!
I'm using MS SQL Server 2k and scripting with ASP 3.0

Hi,I'm working on a simple performance-program, where I need to extractinformation from the 2 newest periods for every performance-indicator- And from there calculate a trend between these results.The problem is, that I can't find a simple way to extract the 2 latestresults.The Table (Table1) looks like this:kpiIDperiodIDActualAcceleration23Acceleration54Speed1100Speed4200Speed7220Speed9180Weight122Weight332Weight721Weight1033If I want to extract the newest I use something like this (made it inMS Access, so the syntax might differ slightly from SQLServer):SELECT table1.kpiID, table1.periodID, table1.ActualFROM table1 WHERE table1.periodID = (SELECT max(t.periodID) fromtable1 as t WHERE t.kpiID=table1.kpiID);BUT - how how do I get the second-newest period as well?Preferably I would like the final result to be a View with thefollowing fields:kpiID, periodID_newest, Actual_newest, periodID_sec_newest,Actual_sec_newestAlternatively a View with 2 posts for each performace-indicator.Thanks in advanceRyan
