Need Query For Latest Time Per ID
Jun 11, 2006
I've been baffled over how to do this without using a script... I would like to get the info I need with a single query.
Here's my scenario, the table looks like this (simplified):
ID, TIME
101, 5am
101, 6am
104, 5am
260, 5am
104, 6am
260, 6am
101, 7am
260, 9am
104, 7am
101, 8am
So basically I have a column of identifications and a column of times. They won't necessarily be in order. I would like a query that gives me this:
101, 8am
104, 7am
260, 9am
It would order the IDs ascending, only showing the newest time assigned to that ID in the table.
Thanks in advance for any help :)

select SERIALNO, Max(TIME)
from dbo.TASK A
join dbo.Status B
on A.TID=B.TID
where A.ID in ('1111',2222')
and A.TYPE='Pen'
group by B.SERIAL_NO, B.TIME
order by BM.TIME
For this query I may get serial no duplicates but times are unique
For that serial no, I have to find the recent time. But if I use group by, I am getting the wrong no

I have 2 tables:
TransactionsImport (which is the destination table)
TransactionsImportDelta
I need to do the following:
Get the records with the latest date and time in the destination table TransactionsImport
Get the records with the latest date and time in the destination table TransactionsImportDelta table
Insert the records from the TransactionsImportDelta table into TransactionsImport that have a greater date & time than the current records in TransactionsImport table.
Problem is date & time are in separate columns:
Table structure:
Date Time ID
2011121305154107142201008300100
2011121305154122B1L13ZY0000A07YD

Is the Date/Time of the latest SQL Server 2005 instance restart stored somewhere in the system catalog?
This value is quite relevant when retrieving information on the costliest unused indexes in the instance.
I know of one way of doing this, which is to search the SQL Logs for this info.
This solution is very unwieldy - we recycle the logs daily and we only keep the logs of the last 7 days.

Hi all,I have the following tableName Date Wish ValidName is person's name, date defaults to getdate() and is neverassigned directly (datetime field), Wish is some message, and Valid isbit, 1 indicates if the wish is the latest, and therefore valid. Allprevious wishes are kept in database, and are "invalidated" by settingthe Valid to 0.So, a typical data set looks like:Name Date Wish ValidJoe 02/01/2007 Ice Cream 0Joe 02/04/2007 Bicycle 0Joe 02/06/2007 PS3 0Joe 02/22/2007 XBox 360 1Mary 02/02/2007 Barbie 0Mary 02/04/2007 Cindy 0Mary 02/06/2007 Barbie house 0Mary 02/20/2007 Get married 1My users want to see the initial wish at some point and another onesome time later (they provide dates). So, if someone wanted to seechanges in wishes between 02/03 and till 02/15, they would get thatJoe's initial wish was Bicycle and the latest that he wanted was PS3.As for Mary, she started wanting Cindy and ended up thinking about theBarbie house.I can do UNION, but is there another way to do that?Thank you.

In summary, the requirement is to fetch the latest upated record for each unique NAME.

Hi,
I have this specific problem, that has been causing me alot of headaches for the last couple of days, and I can't seem to fiure it out on my own.
Basically i am working on a many to one currency conversion setup, where I have a fact table with exchange rates for periods and for all input currencies. The reporting currency is USD. Here is a demonstration of the data in it:
Valid Date Source Currency Rate
2008-01-01 GBP 2.0563
2008-01-01 EUR 1.4634
2008-04-01 GBP 1.9968
2008-04-01 EUR 1.5197
Normal period by period conversion is easy enough, but I want to convert the measures at the latest known rate, based on the period selected. Lets say I run an analysis without slicing on time, then it want it to convert at the last entered rate of all time, and if the user wants to run the analysis as of March 08, then it should convert all data to the rate as of January, since this is the latest one known.
I have tried to set the measure to a semi-additive behaviour, with "lastnonempty", but the problem with that is the conversion over time. Here is an example:
I want to show a measure summed "all to date" as of June 08. What I want is it to convert everything at the rates entered in April 08, but what I get is that it convert everything up until Jan 08 and the rates entered in January, and thereafter it starts to use the rated entered in April.
Period Amount LCY Currency Code Exchange Rate
Dec 07 100 GBP 2.0563 (Wrong, should be 1.9968)
Dec 07 100 EUR 1.4634 (Wrong, should be 1.5197)
Jan 08 100 GBP 2.0563 (Wrong, should be 1.9968)
Jan 08 100 EUR 1.4634 (Wrong, should be 1.5197)
Feb 08 100 GBP 1.9968
Feb 08 100 EUR 1.5197
Mar 08 100 GBP 1.9968
Mar 08 100 EUR 1.5197
Apr 08 100 GBP 1.9968
Apr 08 100 EUR 1.5197
May 08 100 GBP 1.9968
May 08 100 EUR 1.5197
Jun 08 100 GBP 1.9968
Jun 08 100 EUR 1.5197
How do I create a measure containing the latest known rates based on time selection?
Thanks in advance

I have a table T (a1, ..., an, time, id). I need to select those rows that have different id (GROUP BY id), and from each "id group" the row that has the latest field 'time'. Something like SELECT a1, ..., an, time, id ORDER BY time DESC GROUP BY id. This is the wrong syntax and I don't know how to handle this.

Hi all,
hopefully someone can suggest the best way of implementing the problem i am trying to resolve. We have a table which contains rows relating to tests run on our product. This table is populated from an SSIS job which parses CSV files.
There are multiple rows per serial number relating to multiple tests. The only tests i am interested in are the ones with an ID of T120. Here is the query i have so far which should make it a little easier to explain:
SELECT [SerialNumber]
,Param1
,[TimeStamp]
FROM [Build Efficiency System].[dbo].[SSIS_SCANNERDATA_TBL]
WHERE Test = 'T120'
GROUP BY SerialNumber, Param1, [TimeStamp]
ORDER BY SerialNumber
What i have above is fine to a point. The problem i am encountering is that in test T120 it specifies a part which can be be one of about 6 in field Param1. If during testing there is a problem with the part then it is replaced and the test run a second time up until the whole product passes the test. The query above returns all instances of replacements so i may have the out put as follows:
SerialNumber Param1 TimeStamp
0 Part1 15/03/07
0 Part2 15/03/07
0 Part2 16/03/07
0 Part3 15/03/03
What i really need is to only list the last part that is installed, hence the one with the latest timestamp:
SerialNumber Param1 TimeStamp
0 Part1 15/03/07
0 Part2 16/03/07
0 Part3 15/03/03
Can someone please help me to alter the above query so that it will show only those Param1 fields that have the latest date for each part.
Many thanks in advance,
Grant

I have a scenario as below for one ID -
+------+--------+----------------------------+-------+
| id | amount | date | descr|
+------+--------+-----------------------------+------+
| 5689 | 10.00 | 2015-08-25 12:10:57.107 | 4 |

| 5689 | 130.00 | 2015-08-25 12:07:57.107 | 3 |
+------+--------+-----------------------------+-----+
I want to fetch below 3 records from the above scenario i.e. latest record of each amount (Latest is determined using "descr" column i.e. 4 is greater then 3 -
+------+--------+----------------------------+-------+
| id | amount | date | descr|

| 5689 | 130.00 | 2015-08-24 12:07:57.107 | 4 |
+------+--------+-----------------------------+-----+
But in case of same amounts I am unable to fetch the latest status as even using partitioning will treat them as one.
CREATE TABLE #TMP
(

AMOUNT DECIMAL,
[DATE] DATETIME,

I have a SQL query I need to design to select name and email addressesfor policies that are due and not renewed in a given time period. Theproblem is, the database keeps the information for every renewal inthe history of the policyholder.The information is in 2 tables, policy and customer, which share thecustid data. The polno changes with every renewal Renewals in 2004would be D, 2005 S, and 2006 L. polexpdates for a given customer couldbe 2007-03-21, 2006-03-21, 2005-03-21, and 2004-09-21, with polno of1234 (original policy), 1234D (renewal in 2004), 1234S (renewal in2005), and 1235L (renewed in 2006).The policy is identified in trantype as either 'rwl' for renewal, or'nbs' for new business.The policies would have poleffdates of 2004-03-21 (original 6 monthpolicy) 2004-09-21 (first 6 month renewal) , 2005-03-21 (2nd renewal,1 year), 2006-03-21(3rd renewal, 1 yr).I want ONLY THE LATEST information, and keep getting earlyinformation.My current query structure is:select c.lastname, c.email, p.polno, p.polexpdatefrom policy p, customer cwhere p.polid = c.polidand p.polexpdate between '2006-03-01 and 2006-03-31and p.polno like '1234%s'and p.trantype like 'rwl'and c.email is not nullunionselect c.lastname, c.email, p.polno, p.polexpdatefrom policy p, customer cwhere p.polid = c.polidand p.polexpdate between '2006-03-01 and 2006-03-31and p.polno like '1234%'and p.trantype like 'nbs'and c.email is not nullHow do I make this query give me ONLY the polno 123%, or 123%Sinformation, and not give me the information on policies that ALSOhave 123%L policies, and/ or renewal dates after 2006-03-31?Adding a 'and not polexpdate > 2006-03-31' does not work.I am working with SQL SERVER 2003. Was using SQL Server 7, but foundit was too restrictive, and I had a valid 2003 licence, so I upgraded,and still could not do it (after updating the syntax - things likeusing single quotes instead of double, etc)I keep getting those policies that were due in the stated range andHAVE been renewed as well as those which have not. I need to get onlythose which have NOT been renewed, and I cannot modify the database inany way.*** Free account sponsored by SecureIX.com ****** Encrypt your Internet usage with a free VPN account from http://www.SecureIX.com ***

Let's say I have a table of data as per the below..
I'm trying to extract only the green highlighted items..
The rules applied are: Only the latest data concerning all cases, and only 1 line (the latest) per case.
As you can see in the image, I don't want the 2nd,3rd, and 4th record extracted cause they are all superseded by more recent records (identified as they are further in the table).
I've considered using either Distinct or Having? but can't get that to work.. If I could use Distinct but then ensure it's the latest record in the table that would be perfect.

Hi,
I have a table which has a few fields, one being "datetime_traded". I need to write a query which returns the row which has the closest time (down to second) given a date/time. I'm using MS SQL.
Here's what I have so far:
Code:
select * from TICK_D
where datetime_traded = (select min( abs(datediff(second,datetime_traded , Convert(datetime,'2005-05-30:09:31:09')) ) ) from TICK_D)
But I get an error - "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.".
Does anyone know how i could do this? Thanks a lot for any help!

Hi all,
I have created a report in SSRS 2005 which is being viewed by users from different Time Zones.
I have a dataset which has a field of type datetime (UTC). Now I would like to display this Date according to the User Time Zone.
For example if the date is August 07, 2007 10:00 AM UTC,
then I would like to display it as August 07, 2007 03:30 PM IST if the user Time Zone is IST.
Similarly for other Time Zones it should display the time accordingly.
Is this possible in SSRS 2005?
Any pointers will be usefull...
Thanks in advance
sudheer racha.

I need to time a query down to hundredths of a second. I can see from the runtime clock in SQL Studio that my query ran for 00:00:00. However, I need to know exactly how long it took.
Thanks for your help!

Hello,I have a table that lists a number of available time slots for a party venue. I want a user to select a particular time slot and have the query show results for that time slot plus two time slots before and two time slots after the user's selection. If the user selects a time slot that is the first of the day, I still want that user to be shown 5 results including the one he selected. The same goes for the last time slot of the day. Can anyone help me with the SQL statement?
Thank you very much in advance!

I am using SQL Server and ASP.NET. I am executing a couple of stored procedures and displaying the results in a datagrid. Since these Stored procedures takes around 2-4 minutes each, I want to display a status bar on the web by displaying the approximate time the user needs to wait before seeing the results.
My question is: Is there a way to find out the approximate EXECUTION TIME of the stored procedure before hand. Also, if that is possible, how do i access the same from the ASP.NET code..
Thanks

I have a server with two test instances of a data base. I have a query which creates a temp table, inserts 29 rows, perform 4 update queries to add counts and then dumpps out the results. This entire query script runs 1.33 minutes on one instance and 2.5 minutes on the other. On the production server this query now runs in 9 seconds. If I run any one of the test updates individually they execute under 2 seconds, just like the production server.
THe results are repeatable.
All are SQL 7 with all service packs on NT4 sp6. Both test data bases are backups of production from last week. I suspect some kind of caching/buffer problem, but I do not know what to look for. I am not a DBA so I have no idea what role TEMPDB plays may play in this.
Can anyone give us ideas on where to look for the performance difference? Will our impending upgrade to SQL2K solve this problem or make it worse? Any ideas would be appreciated.

Why is the response time to run a query faster when the output is displayed in grid format as compared to text format?

Hi, We have a SQL 7 / Win2K cluster and yesterday afternoon the users were complaining about poor performance. Their queries were timing out.. (Not all of them, just some on some large tables)
I ran just an ad-hoc query against the table from my machine and I also timed out. THen I went right to the box that had control of the cluster and did the same thing there and also timed out. Because of time constraints (and we are in testing mode) we tested a failover and everything was back to normal after that.
So now we want to try to figure out what could have been the problem. At the time I checked out the Memory and CPU usage and they were very low (0-5%) and using only 1/3 of the memory. It couldn't be a bad query or index because after the failover it worked fine.
Could there be something wrong with the specific box that had control at the time? I dont' know where to look?
Any ideas would be appreciated!

Hi,
I am running this query and it is taking over 3 minutes.
"select * from table1 where CONVERT(varchar(10),dated,5) = '13-09-01' "
Table1 has a column called dated which is datetime datatype.
Any suggestions how can i optimize this query?I tried Non-clustered index on Dated column and time came down to less than 3 but still more than 2min.
TIA.
