PREVIOUS FUNCTION
Mar 27, 2008Has anyone used the 'previous' function to return the previous row of data? I have tried this
=previous(Fields!SomeColumn.value) - when I run the report, no data returns.

SQL 2012 :: Using LEAD Function To Show Previous Month Difference?
Mar 25, 2014I have 12 month report and I need show volume and difference between current and prev month volume, what is the smart way to do this, do I need to put prev month value onto same row horizontally? I think should be some other smart way, I heard about LEAD function?
This what I think for now, It should be listed per ClientID also, in my example I have single ClientID for simplicity.
I tried to do LEAD but with not success..

IF OBJECT_ID('tempdb..#t') is not null drop table #T;

SELECT N as Rn,

Transact SQL :: Window Function To Count Number Of Rows In The Previous 24 Hours?
Nov 16, 2015is it possible to use the window functions to count the number of rows in the previous 24hours from the current row.
I have a table of events like:
User, TimeStamp, etc...
I want to identify the row which is the event number 50 in the past 24 hours.
does the window functions can do this? and how?
the ROW PRECEDING etc... appear to not have enough feature to support time related function.
Stream-insight is able to create this type of query, but I have to do it directly in SQL.
Compare The Value Of A Variable With Previous Variable From A Function ,reset The Counter When Val Changes
Oct 15, 2007I am in the middle of taking course 2073B €“ Programming a Microsoft SQL Server 2000 Database. I noticed that in Module9: Implementing User-Defined Functions exercise 2, page 25; step 2 is not returning the correct answer.
Select employeeid,name,title,mgremployeeid from dbo.fn_findreports(2)
It returns manager id for both 2 and 5 and I think it should just return the results only for manager id 2. The query results for step 1 is correct but not for step 2.
Somewhere in the code I think it should compare the inemployeeid with the previous inemployeeid, and then add a counter. If the two inemployeeid are not the same then reset the counter. Then maybe add an if statement or a case statement. Can you help with the logic? Thanks!
Here is the code of the function in the book:
/*
** fn_FindReports.sql

** This multi-statement table-valued user-defined
** function takes an EmplyeeID number as its parameter
** and provides information about all employees who

Next/previous Record
May 2, 2007Hi. Is it possible in SQL query to find record previous or next in comparison with record found with clause WHERE (example of query below)? I need to find record with ProblemID less than or greater than 10. Regards Pawelek.
SELECT ProblemIDFROM dbo.tblProblemsWHERE (ProblemID = 10)
Last And Previous Query
Mar 20, 2004I'm kindof at a lose for how to ask my database to show me the last payment amount and payment date for clients and also show me the previous payment amount and payment date for clients based on a date range.
Could anyone offer any pointers or examples?
Thank you very much.
We could use a very simple table and field setup like this just so you could show an example:
tblClient
Client_ID
tblOrder
Order_ID
Client_ID
tblOrderPayments
Payment_ID
Order_ID
Client_ID
PaymentDate
PaymentAmount

Previous Value Best Method
Jan 25, 2006I'm not really strong in SQL. My goal is to compare the beginning mileage of a vehicle record with it's previous ending mileage reading. I have something that works, but it feels clunky. I wonder if there is a better method, ie a join. Here's what I have:
SELECT A.Trolley_num, A.Date, A.Speedo_start, A.Speedo_end,
(SELECT B.Speedo_end FROM Daily_Trolley AS B
WHERE B.Trolley_num = A.Trolley_num
AND B.Date =
(SELECT Max(Date) FROM Daily_Trolley AS C WHERE C.Trolley_num = A.Trolley_num
And C.Date < '1/23/2005')) AS PrevSpeedoEnd
FROM Daily_Trolley AS A
WHERE A.Date='1/23/2005'
ps: I inherited this db; I'm aware that "Date" should not have been used as a field name.
Previous Value Retrieval
Jul 10, 2006I have a table of vehicle usage records with fields including vehicle number, driver, date/time, starting odo, ending odo. I'm looking to compare the starting odo of a given record to the ending odo of the last time that vehicle was used. I also need to return other fields from that previous record, like the date/time and driver.My users basically run a report for any given day, and the vehicles used on that day need to be compared to their most recent usage (most recent relative to the record at hand). This is to ensure that the vehicle hasn't been used in the interim and not recorded (which may indicate theft).I've got a very convoluted process in place, but I'd like to see if it can be streamlined. The current process is done in Access and has a number of queries built on other queries. It is very slow. The data is in SQL Server. Any thoughts on the best ways to accomplish this?TIA

Images :: Next, Previous, First, Last Functionality
Jul 3, 2007currently have my website that is functional...but would like to add some navigation to my photos which are displayed using a repeater tied to a SQL database. (live example can be viewed here)
the above link shows a gallery page that displays all the photos within a given shoot (using a querystring to display the unique ID of the photo shoot). When you click on one of the images within the shoot a page called is called displaying the selected photo by passing the shoot ID and the unique ID of the photo itself through a querystring.
I would like to add navigation to the page displaying the photo that would allow the user to go to the next photo, previous photo, first and last phot within the specific SHOOT ID.
FirstNextPreviousLast
I am using a repeater to display the photo with the following sqlDataSource:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:Connection %>"SelectCommand="SELECT usr_Photos.*, usr_PhotoShoot.* FROM usr_Photos INNER JOIN usr_PhotoShoot ON usr_Photos.Shoot_ID = usr_PhotoShoot.Shoot_ID WHERE usr_Photos.Photo_ID = @ID AND usr_Photos.Shoot_ID = @Shoot"><SelectParameters><asp:QueryStringParameter DefaultValue="" Name="ID" QueryStringField="ID" /><asp:QueryStringParameter DefaultValue="" Name="Shoot" QueryStringField="Shoot" /></SelectParameters>
</asp:SqlDataSource>
I am having trouble figuring out a way to add the functionality i would need to change photos within the specific photo shoot without having to go back to the gallery page. any help or ideas you could point me in would be great...thanks in advance...

Combine Tables From Previous Db To New Db (uhh...?)
Nov 2, 2003I'm wanting to migrate an existing customer's database into a new products db. The previous contractor used seperate tables for each product type, where I chose to use one "products" table.
My challenge has been that the previous db uses attributes that aren't common across all products. Would it be best to do a products_attribute table? If so, how would I query the previous products db and seperate the information during an insert between "product A" and "product A attributes"?
Sample existing table:
ID, Name, Price, Weight, Attr1, Attr2, Attr3, Attr4, Attr5, Attr6
New table: Products
ID (auto), ProductName, Price, Weight
- Products_Attribute table
- ... ?

Check Previous Row In The Table
Jul 9, 2004Hi...
Is there any way to check previous row in SQL Query?
I have a table with these column :
Name1
Name2
Audit_Time (datetime)
Changes
I want to delete record from database in which the Audit_time is <'01/05/2004'.
However before deletion, I want to check, if the Changes value is 'OLD' And the previous value is 'NEW', I will check the Audit_time of the NEW instead of OLD.
Table :
Row Name1 Name2 Audit_Time(mm/dd/yyyy) Changes
1 ABCD EFGH '01/01/2004' ADD
2 ABCD EFGHIJ '01/04/2004' NEW
3 ABCD EFGH '01/04/2004' OLD
4 Klarinda Rahmat '02/08/2004' NEW
5 Klarinda Rahmat '01/04/2004' OLD
In this case, I want to delete row 1,2,3 Where the audit_time are < '01/05/2004'.
Row 5 the audit_time also < '01/05/2004', however the changes='OLD' and the previous value changes='NEW', so I will check the Audit_Time of row 4 which is not < '01/05/2004'.
So I can't delete row5.
Is there any way to check previous row or the row before a specific row in SQL.
Any suggestion is welcomed.
Thank you in advanced.

T-SQL (SS2K8) :: Set Value Based On Previous Row
Apr 11, 2014I am trying to code a rule at the moment which sets a value based on the value of the previous row. This is as far as I have got so far. I am trying to run it as a set based command and I believe I may need to make use of a numbers table.
Anyway the code is....
declare @data table
(ID int identity(1,1),
DeviceID int,
EventTypeID int,
EventID int)
[Code] ....
So the output is currently incorrect. Each DeviceID needs to have a ID assigned to the MIN(ID) which isn't yet in the code above. This ID has to be sequential across the full table and not dependent on ID.
Next the rule is coded in the case statement above.
So for each DeviceID, when the EventType goes from 1, 2 or 4, to 0 or 3, the following record after the 0 or 3 will have a new EventID. And conversely when the EventType goes from 0 or 3 to 1,2, or 4, the record that is the 1, 2 or 4 will have a new EventID.
