SQL 2012 :: Accurate Sorting Data Each Time With Millions Of Records Without Time Field?
Apr 25, 2014
Sample Table
USE [Testing]
GO
/****** Object: Table [dbo].[Testing] Script Date: 4/25/2014 11:08:18 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
[Code] ....
It seems to work fine with one million records.
Each primary key is unique, but the begindate is non-unique, and i guess even if i use datetime2 and add nanoseconds, from what i have read, there is a chance that i could have a duplicate datetime since the date is imported via XML from multiple sources.

Hi,There are about 30 millions records on my mssql server and I want to access 2 million of them at one time. However, when I try to access with sql command I get time out error.

May I obtain this?For example;select * from tbl_Customer where name = @name_ ->time out errorSomeone has said that you can solve this problem with < cursors > but I can't find enough article.

I do hourly transaction log backups at 9,10, 11 etc...
When I restore from a 9:00 backup I clearly see changes that I made after 9:00 am!!!
I then noticed when I go to my scheduled backups that a 10 am backup was indeed done
but in the "restore from device" tab it says the last backup was at 9 am.
Apparently it is not showing the actual latest backup that was done. This explains why
when restoring from a 9am backup I am seeing changes after 9, because in reality
I am restoring from a 10 am backup!
Is this a bug? I am running on 6.5 sp 5a.
thanks in advance....Mary

I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.
E.g.
Query 1
Select ID, Person, ProposedEvent, DayField, TimeField
from MyOptions
where person = 'me'
Table
Select Person, ExistingEvent, DayField, TimeField
from MyTimetable
where person ='me'
Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.
I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.

I am developing a form for a mortgage company. There can be any number of borrowers on a given loan, and the business has asked that this form return only 2 borrowers at a time for a loan. For example, if there are 3 borrowers for a loan, they want the first copy of the form to print the first 2 borrowers and then another copy of the form to print the 3rd. No matter how many copies are printed, they want the borrower information to be labeled as 'Borrower1' xyz and 'Borrower2' xyz. Also, there will be a LOT more fields returned on the real form, so the sample information below is very simplified test data.
Sample Data:
CREATE TABLE #t (LoanID VARCHAR(5), BorrowerName VARCHAR(20), BorrowerOrder INT);
GO
INSERT INTO #t VALUES
('::E', 'John Smith', 0)
, ('::E', 'Jane Smith', 1)
, ('::E', 'Rob Jackson', 2)
, ('AF_CF', 'Sloan Burton', 1)
[code]...
I don't want that 2nd record to return. This result is what makes me think of gaps and islands, but I don't know if the 2nd record is really an island since it's (1) not stored this way...it's returning this way because of the query and (2) it's not sequential data..I tried restricting this by putting this into a CTE and then returning only the odd numbered records like I have below. This runs pretty quickly when dealing with one loan. But...I am concerned that the CTE will be slow when we run batches of loans.
Attempt with CTE:
--With CTE
;WITH cte AS
(SELECT
Borrower1 = BorrowerName
, Borrower2 = LEAD(BorrowerName) OVER(ORDER BY BorrowerOrder)
, RowNumber = ROW_NUMBER() OVER(ORDER BY BorrowerOrder)
[code]...
Is there a better, cleaner way to do this? Or is the CTE the best way to go?

I hope to update a DateTime column value with a Time input parameter. Poor attempt below but it looks like the @ApptTime param is coming in as 10:45:00.0000000 and I might have an existing @SendOnDate as: 2015-10-05 07:00:00.000...I hope to end up with 2015-10-05 10:45:00.000
ALTER PROCEDURE [dbo].[SendEditUPDATE]
@QuePoolID int=null
,@ApptTime time(7)
,@SendOnDate datetime

I have a table that contains an employee id and dates signifying time periods that those employees were working. I need to calculate anniversaries, such as 20 year, which are the sum of all periods spend working projected out to 20 years. For example,
emp_idstart_date end_date
1001 1998-01-01 2003-06-21
1002 1999-05-23 2008-03-28
1001 2004-08-19 NULL
1003 2004-10-12 2006-07-25
1004 2005-04-28 NULL
1002 2008-11-02 NULL
1003 2009-05-17 NULL
The periods in which the employees were inactive (the time period between active ranges) would push back their anniversary date, obviously. I'm only concerned with employees that are currently active (ie. the most recent record has a NULL end date). I thought about trying to use datediff to calculate the time between active periods, but I'm not sure how to go about doing it.

I need to take a temporary table that has various times stored in a text field (4:30 pm, 11:00 am, 5:30 pm, etc.), convert it to miltary time then cast it as an integer with an update statement kind of like:
Update myTable set MovieTime = REPLACE(CONVERT(CHAR(5),GETDATE(),108), ':', '')
how this can be done while my temp table is in session?

I have a date/time field with a sql format of "datetime" The actualdate/time data format is MM/DD/YYYY^hh:mm:ss:pm or "1/25/200712:00:16 AM" Both the date and time are combined on the same fieldwith a space seperating the two.I need to run a query on this date/time field using the criteria oftoday's date so if I want to search all records with todays date, Ineed to query on this field. I don't need the time, but just today'sdate (MM/DD/YYYY) portion of the field.Thanks,Brian

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

We are using SQL Server 2008 as our database and use Access as a GUI. I am looking to create a form in Access where employees can access their time card and request changes from management. I want to use the format from the attached screen shot for the form. I pretty much know how to do it all, the only point of complication is trying to figure out the easiest way to get the transaction punch record data on employee_punch_record into a format where I can easily populate the form in the horizontal format you see in the screen shot.
I am not super strong in SQL, but figure I can do it using a formatting table of some sort. quick and easy way to move transaction records into a more horizontally oriented record?

I've got a table where the date and time fields are all out of sequence and I need them in sequence when I am extracting data from the table, but I'm having trouble writing the SQL.
I've got this line which sorts the date and time for the table:
SELECT * from tblcodegreydiv order by date desc, time desc
Now I'm trying to retrieve the closest record prior to a date,time selected by a user...
SELECT * from tblCodeGreyDiv
WHERE recid=(SELECT MAX(recid) from tblCodeGreyDiv WHERE date + '' + time <= '2007-09-19 05:24')
I need to somehow sort the table before I run the above sql statement. How would I go about doing this?

Hi All,
I've looked around but can't seem to find an answer for this.
I have a cube that has a fairly large time dimension (going back to 1949) as the data demands this.
When a user is browsing the cube and applies a filter or adds the a time heirarchy as a value it's always sorted from oldest to newest. Whilst the need is there to look at data from 1949 most people want to look at the last few years. The problem is they have to scroll right down the list to get to this. Is there a way of having the most recent years of the time dimension appear first in these lists to make them more accessable?
I hope that makes sense!
Any help would be appreciated.
Thanks

Last weekend many of our severs had a failed job "collection_set_3_upload". The error that occured is: "Violation of PRIMARY KEY constraint 'PK_ active_ sessions_ and_requests'. Cannot insert duplicate key in object 'snapshots.active_sessions_and_requests'. The duplicate key value is (2824333, 2015-10-25 02:54:49.7630000 +02:00, 1)."Last weekend we happened to go from summer time to winter time. i.e. the clock passed 02:00 - 3:00 two times during this night.
I.e. there is a bug in the Data Collector component that collects data for the Management Data Warehouse: it uses local time instead of UTC. I've created a Connect item to report it to Microsoft.URL...how do you get your process running again? the job will no longer run because it will every 5 minutes keep on trying to upload the conflicting data for the 2nd 2:00 - 3:00 period. I've only found one solution: get rid of all data collected but not yet uploaded.
You do this by stopping the Collection set (in SSMS go to Object Explorer -> <the server you want to fix> -> Management -> Data Collection -> System Data Collection Sets. Right click "Query Statistics" and select "Stop Data Collection Set").Then you delete the cached results from the sql server machine's harddisk. These cached results are in files located in a Temp folder on the sql machine itself, inside the AppData folder for the service account SQL Server Agent is running under. Usually it will be something like: c:Users<sql agent service account>AppDataLocalTemp.
Inside this folder delete all files that have 'QueryActivity' in their name. You'll loose all data collected since the start of wintertime, but at least your data collection process will work again.After this you can start the Collection set again by right clicking it and select "Start Data Collection Set". Every 5 minutes the data will be summarised and uploaded into your management data warehouse.

Hello,Currently we are in the process of implementing a sql server database where couple tables will have millions of rows ( about 98 millions and will grow) and a web site that will retrieve and sort the data ( read only). How asp.net gridview and sqldatareader act situation like that? Will it be a very slow response? Is there any alternative? Is there any example on the net?
Assuming tables are well tuned and well indexed.
Thank you in advance.

I am currently investigating aa high avg write time ms issue (145ms) which seems to be only occuring on the tempdb data files.I have followed the recommended setup of TEMPDB in that
1. Data files = number of physical cores
2. Data files and logfiles are on separate partitions away from the other databases.
3. Tempdb is presized and no incremental file increases look like they are happening with frequency.
We have sharepoint 2012 setup on other sql servers and with TEMPDB setup following the same guidelines, with far more Sharepoint activity on a similary specified hardware which is why its confusing.FileIO auditing on the partitions themselves shows that the FileIO is very fast on the partitions that the tempdb data file which leads me to beleive that Sharepoint may be the culprit perhaps due to excess use of tempdb with operations taking a long time to resolve.

We have an SSAS instance where when we run the query "select * from $system.discover_traces" the creation time in the resultset shows a different time from when we actually started the trace.
for example if we have create the trace at 3.30pm it shows 7.35 pm in the Sql server management studio resultset when we run the query "select * from $system.discover_traces".

I have deleted nearly 30 million rows from a table. But however when I used the sp_spaceused command to calculate the data occupied by the table I don't see any difference in the data size of the table. In fact the data has increased to few MBs after the deletion, but not much.

Hi, all experts here,
Thank you very much for your kind attention.
I encountered a very strange problem again. Why the time series displayed on the chart are so strange? The Key time column I chose for my time series algorithm is cal_month(e.g 199001...), but why the date displayed on the time series chart is like :05/06/2448? (it should be like 199001..?) What is that data? And where exactly did it come from? What is the exact cause of this?
Hope it is clear for your help.
I am really confused on this and thanks a lot for your kind advices and help and I am looking forward to hearing from you shortly.
With best regards,
Yours sincerely,

Hi there.
I'm trying to extract data from my SQL server & everything in the script I've got is working (extracting correct data) except for one field - which is for the most part it's off by +2 days (on a few occasions - I see it off by just +1 day or even +3, but it's usually the +2 days).
I'm told that it's due to the conversion formula - but - since SQL is not my native language, I'm at a bit of a loss.
The DB table has the date field stored as a type: CHAR (as opposed to 'DATE')
Can anyone out there help?
Please advise. Thanks.
Best.

207 01/01/2008 15:00:07 server2 Up
208 01/01/2008 15:00:08 server3 Up
I made a view that brings all the events of an especific server, let say server 1, the view shows:
Event ID Date Server Status
200 01/01/2008 15:00:00 server1 Up
203 01/01/2008 15:00:03 server1 Up
206 01/01/2008 15:00:04 server1 Down
The objective: Calculate the uptime for a server.
The question is:
How do I calculate the time elapsed between one record of the view and the previous one?
I will appreciate any help you could provide me.

I have a report where I am giving the users a parameter so that they can select which field they would like to sort on.The report is also grouping by that field. I have a gruping section, where i have added code to group on the field I want based on this parameter, however I also would like to changing the sorting order but I checked around and I did not find any info.
So here is my example. I am showing sales order info.The user can sort and group by SalesPerson or Customer. Right now, I have code on my dataset to sort by SalesPerson Code and Order No.So far the grouping workds, however the sorting does not.
Any suggestions would help.

Hi,
I get 5000 records on executing a query.
In the form, I would like to display 50 records at a time in the grid from this resulted query, so i create 100 link labels(dynamically created based on the no. of records resulted from the query) within a panel.
When clicked on link1, first 50 records should be displayed,on clicking link2 next 50 records(ie, 51 to 100) should be displayed and so on.
So , i wrote the query as---
select top(50)* from tblindividual where id not in (select top(intValue)id from tblindividual )
where intValue would be 50 for link2,100 for link3,150 for link4 and so on
If i want to fetch last 50 records of the query, intValue would be 4950.Here the "not in" list becomes very big(1,2,3,.......,4949,4950) and hence the query is becoming a bit slow...
Is there any other method(query) to get the same result??.. because i heard that using "not in" keyword would make query execution slow.

Hello All,
I have some difficulties with TSQL where i need to calculate time between two records in seconds.
Records look like this:
ID IP DATE CHANNEL_ID #CALCTIME
1 10.132.184.226 12/06/2007 08:00:00 406 35
2 10.96.121.230 12/06/2007 08:00:10 1 45
3 10.128.242.214 12/06/2007 08:00:20 4 39
4 10.132.184.226 12/06/2007 08:00:30 2
5 10.96.121.230 12/06/2007 08:00:55 3
6 10.96.121.214 12/06/2007 08:00:59 3 21
7 10.96.121.214 12/06/2007 08:01:20 4
.........................................................................................................
Basically i would need to calculate the time between 2 records with the same IP (next one with the same IP) and calculate the time between the DATE which is basically attached to the first record. As you can see the first #CALCTIME is done between the ID #1 and ID#4 which means that the time difference must be done between the current and the next record.
Really appreciate your help!
Thank you!

I looked at this post and it didn't work for me.
Trying to extract the time portion from a datetime field. ex 7:15:12 AM from 1/1/2008 7:15:12 aM
This is what I tried and neither functions give me the results I want....
SELECT DueTime, CONVERT(varchar, DueDate, 108) AS Expr1, SUBSTRING(CAST(DueDate AS varchar), 10, LEN(DueDate)) AS Expr2, CAST(DueDate AS varchar) AS Expr3FROM TODO
Due Time Expr1 Expr2 Expr3
1/1/2008 5:15:00 PM 00:00:00 12:00:00 AM Jan 1 2008 12:00:00 AM
It seems Cast(DueDate as varchar) is the problem it converts the time to the default 12:00:00 AM
In the above example I want 5:15:00 PM
Tx in advance

Hi,
I'm trying to use the Update command to change a field value. I only know the field name at run-time, how do you write this command. This is what I have done which just sets the variable @cFieldName to the value and not the field within the table.
UPDATE [Atable] SET @cFieldName = @aValue WHERE ([Id] = @Id_1)
