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.
I have got a table with GUID (PK), COMPANY, CONTACT. There are going to be instances where the company name is the same on multiple records.
What i am trying to do is work out what is the next and previous record
The data is going to be sorted, by COMPANY then GUID.
I am think a stored procedure would be the best to combact this, but very usure how to go about writing it, so i passed the present company and GUID values to it.
Any help would be appreciated, and thanks in advance.
just wondering, if I can get help with a table (Table A) , where there are few dates and numbers, I have to relate this table to another table (Table B) , where I have whole year working dates
I want to write an expression while making dataset, that if date in table B matches table A, it just get the number from the next column from table A, if it does not matches - it should go back to the date (in table A) - where there is a number.
Like table B has working dates for march, but there are only two dates in table A , for 3/2 (and number is 300) and 3/20 (number 200). So In dataset I want all dates from table B and from 3/2 to 3/19 300 in number column and 200 on 3/20.
I'm creating a report in SSRS where we want to do a week-over-week or month-over-month analysis. We have each month and the metrics in a table. By sorting the table ascending, I can grab the previous record using the Previous function in a cell. However, when I order the table descending the previous record is not the correct record to get. In that case I want to grab the next record rather than the previous record. How can I invert the previous function? Or how can i grab the next record in the table rather than the previous?
I want to find previous date from selected date. below is the sample data.
DECLARE @StartDate SMALLDATETIME = '1/11/2016'
declare @tempdat table(repdate smalldatetime) insert into @tempdat values ('10/26/2015') insert into @tempdat values ('10/29/2015') insert into @tempdat values ('11/1/2015') insert into @tempdat values ('11/27/2015') insert into @tempdat values ('11/25/2015') insert into @tempdat values ('11/20/2015') insert into @tempdat values ('11/10/2015') insert into @tempdat values ('11/10/2015') insert into @tempdat values ('11/11/2015') insert into @tempdat values ('11/11/2015')
Now if i pass the date '10/26/2015' then i want select prev date of passed date. in this example no prev date is available, so result set would be nothing.
if i pass the date '11/10/2015' then result should be '11/1/2015' which is prev small date available in table.

I am pulling down out of range values from a single table on one database to a different table on a different database on a different server (one i have full access to). Basically, it looks something like this:
id1 value1 prev_value1 value2 prev_value2 date prev_date id2 value1 prev_value1 value2 prev_value2 date prev_date id3 value1 prev_value1 value2 prev_value2 date prev_date
all the "prev"'s are null. I want to do one do one query that will get me the previous values and dates for each id from the original database. how to do this.

How do I tranfer a previous table and its data to the ASPNETDB.MDF in the Web Site Administration tool. I've tried right, but I can't locate the database in the SQL server on my server. help please.
I have a table with score info for each group, and the table also contains historical data, I need to get the ranking for the current week and previous week, here is what I did and the result is apparently wrong:
select CurRank = row_number() OVER (ORDER BY cr.CurScore desc) , cr.group_name,cr.CurScore , lastWeek.PreRank, lastWeek.group_name,lastWeek.PreScore from (select group_name, Avg(case when datediff(day, asAtDate, getdate()) <= 7 then sumscore else 0 end) as CurScore
[Code] ....
The query consists two parts: from current week and previous week respectively. Each part returns correct result, the final merged result is wrong.
Hi. 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)
I'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:
I'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.
I 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
Ok so someone answered my last quesiton about finding what tables are in a Stored procedure. Is there an opposite of that. If I wanted to type in a table and it shows all the stored procedures that use that table.
Please see DDL and INSERT statements below.Let's say that some process throws out the second row, where theClocktime = '02/01/2005 12:34'Without the use of a cursor, how can I retrieve the PREVIOUS value forthat employee? Pseudo SQL might be something like:SELECT*FROMtblTestWHEREfldCLocktime = THE-ONE-IMMEDIATELY-BEFORE '02/01/2005 12:34'ANDfldEmployeeID = 1TIAEdwardif exists (select * from dbo.sysobjects where id =object_id(N'[dbo].[tblTest]') and OBJECTPROPERTY(id, N'IsUserTable') =1)drop table [dbo].[tblTest]GOCREATE TABLE [dbo].[tblTest] ([fldTestID] [int] IDENTITY (1, 1) NOT NULL ,[fldEmployeeID] [int] NULL ,[fldClocktime] [datetime] NULL ,) ON [PRIMARY]GOINSERT INTO tblTest(fldEmployeeID,fldClocktime)VALUES(1,'01/01/2005 12:34')INSERT INTO tblTest(fldEmployeeID,fldClocktime)VALUES(1,'02/01/2005 12:34')INSERT INTO tblTest(fldEmployeeID,fldClocktime)VALUES(1,'03/01/2005 12:34')
Has 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.
Newbie question. I am using a query that pulls month-to-date data that has the following where clause:
WHERE (MONTH(datefield) = MONTH(GETDATE())) AND (YEAR(datefield) = YEAR(GETDATE()))
this works just fine but what I would like for it to do is give me the previous month of data if the if it's the first day of the month and then any other day give me month to date. Is this possible?
Let me explain. When retrieving a row, an extra column should be added.It's value should be the sum of previous rows whose type is the same with the encountered one. I made it with a function but it's performance was terible with large tables. I have tables larger then fifty housands rows.

currently 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...
I use the following sql in a view to return the last payment date and amount made by clients. What I need is a way to return the payment date and amount for the payment prior to the last one.

I'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"?
