Value Of A Record Based On A Previous Record

Jul 20, 2005

I hope you can help me. I posted this in the microsoft sql server newsgroupa few days ago and got no response so I thought I'd try here. If I canprovide any clarification I'll be glad to do so.I'm trying to calculate a column based on the value of the previous record.I'm not very experienced with SQL-Server.I'm using the following table:CREATE TABLE tblPayment([PaymentID] [int] IDENTITY (1, 1) NOT NULL ,[LoanID] [int] NULL ,[PaymentPeriod] [int] NULL ,[PaymentRecDate] [datetime] NULL ,[PaymentAMT] [money] NULL)I have a view based on this table. That view has the following calculatedcolumnsBeginningBalance: For the first record, this is equal to the loan amountfrom the loan table. For each additional record this is equal to the endingbalance from the previous payment record.Interest: BeginningBalance * the monthly interest rate from the loantablePrincipal: PaymentAMT - InterestEndingBalance: BeginningBalance - PrincipalIt might seem I could use a subquery to calculate the Beginning Balance asin:SELECT LoanID, PaymentPeriod, PaymentAMT,(SELECT SUM(PaymentAMT) FROM tblPayment AS tbl1WHERE tbl1.LoanID = tblPayment.LoanID AND tbl1.PaymentPeriod <tblPayment.PaymentPeriod) AS BeginBalanceFROM tblPaymentWHERE (LoanID = @LoanID)But this will not work, because the interest is calculated on the previousmonth's balance. I need to find a way to loop through the recordset. Isthis possible?Thank you,--Derek CooperDatabase9www.database9.com

Selecting Next And Previous Record

Jun 25, 2004

I'm trying to add a next and previous button to a popup window I have on a photo gallery -

Having trouble with the sql

I know I would have 2 select statements that would each return 1 result set.

I know how to get the top ( and bottom by ordering descending and doing Select Top 1)

But how would I get the next one up!

I would hate returning the entire image section and perform the calcuation in the business tier :(

RANK Get Previous Record But Not Always

Apr 16, 2014

I need to get the previous price for all my PROMOTION records but not when the previous record is a type PROMOTION also it needs to keep going back to get the price.

I have created a table with RANK in which works OK to get previous price for all but how can I say if previous price is type PROMOTION go to next previous prices...

Bets way to show an example is with a jpeg image I have but having trouble inserting into this message...

SELECT a.[StartPrice]
,a.[ProductID]
,a.[Colour]
,ISNULL(b.[Price],a.[Price]) AS [Price Before]
,a.[Price] AS [Promotion Price]

[Code] ...

Table

[Code] ....

Want I'm trying to do select PriceCode PROMOTION and get previous price:

Get previous price
PROMOTION29-Nov-1301-Dec-13Wheel1BLACK31.2039.00

But in this example it picks up the PROMOTION before and I need to ignore this and get rank 1 price for both

How To Reference A Previous Record

Mar 31, 2015

I have a query that shows me a list of what employees that are on site assuming that employee badged in correctly. My problem is I need to know when an employee has two entries in a row that are "In" without have an "Out" entry.

For example, if John badges in at 8:00 Am and leaves without badging out, when he arrives the next day at 8:00 AM and badges in the system simply would show him as in with no record of him ever leaving correctly.

I am not sure how to return the correct result. Can I formulate a query that would display a Who's In list where the previous entry was NOT and Out?

Getting Previous Record From Another Table

Apr 9, 2008

Hello

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.

Thanks in advance for your help

Get Next Record In A Table Rather Than Previous

May 19, 2008

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?

Thanks!

Fast Way To Get Values From Previous Record

Jul 20, 2005

Hello,I know that I've seen this question asked on here before, but I can'tfind an answer that gives me the performance that I need.I have a table that stores events for users:CREATE TABLE Lead_Action_History (lead_action_seq INT IDENTITY NOT NULL,lead_action_date DATETIME NOT NULL,lead_seq INT NULL,operator_id VARCHAR(20) NOT NULL,call_time INT NOT NULL,CONSTRAINT PK_Lead_Action_History PRIMARY KEY (lead_action_seq) )GOThe table has a foreign key to another table through the lead_seqcolumn:CREATE TABLE Lead_Master (lead_seq INT IDENTITY NOT NULL,state CHAR(2) NOT NULL,CONSTRAINT PK_Lead_Master PRIMARY KEY (lead_seq) )GOI need to write a query that will give me a sum of call_time brokendown by a column that is in the table joined through the lead_seq.However, if the lead_seq for a row is NULL then I need to use thelead_seq for the previous row (based on lead_action_date) for the sameoperator.This is what I came up with:SELECT LM.state, SUM(call_time)FROM Lead_Action_History LAHINNER JOIN Lead_Master LM ON (LM.lead_seq = LAH.lead_seq)OR (LAH.lead_seq IS NULLAND LM.lead_seq = (SELECT TOP 1LAH2.lead_seqFROMLead_Action_History LAH2WHERELAH2.operator_id = LAH.operator_idAND LAH2.lead_seqIS NOT NULLORDER BYLAH2.lead_action_date DESC))GROUP BY LM.stateThe problem is that Lead_Action_History has millions of records andany solution that I've found involves one or more subqueries on itwhich kills performance. I am going to look at using a covering indexwith the solution above, but I thought that someone here might haveanother way of doing this.I can't really change the structure, but I can play with the indexing.I would still be curious though how other people model this type oftemporal data in a way that makes it easy to work with.Thanks!-Tom.

How To Check Previous And Next Record Values

May 22, 2008

Hi all,

I wanted to check the previous and next record values.

For example:

sKey NextKey PreviousKey

1 2 Null
2 8 1
8 5 2
5 null 8


Ex : In the first record of the table, the NextKey is pointing to 2.
So the next record of Skey will be 2. The Next Key for this record is 8. Like wise the next record of this should have the Skey as 8.

Now I need to check whether the NextKey and SKey are correct for all rows.

For that I need to check the previous record of "Next key" and next record of "Skey".

Any idea?

Regards
Helen

How To Automatically Populate A Field With A Value From A Previous Record?

Mar 16, 2008



Was wondering if there is easy anyway to autopopulate a field by pulling a value from a field in the previous record?

For example, I have a table with fields name "Dist_From" and "Dist_To". When I add a new record I would like it to populate the "Dist_From" field with the "Dist_to" value from the previous record.

TIA

SQL Server 2012 :: Trigger For Updates On A Row Using Previous Record Value?

Mar 9, 2015

I am looking to update a record from a previous row. So if there is a value of total goods in week 1, i want that value to carry forward to the value of goods in week 2. Is there any SQL as an example of the best way to accomplish this? I can query it using lag() which works great but i need the source data itself to update as the end-users are accessing the data via lightswitch, so when they save a change, i want the trigger (or whatever you recommend) to update the source table.

SQL Server 2012 :: How To Remove Next And Previous Record Amount Equal To 0

Jun 2, 2014

Having below data. SHCOMP (Customer ID), CBLNAM ( Customer name), SHDESC (service description), SHAMT (service charge), SHTYPE (F-> From T-> To)

CREATE TABLE #Temp(
[SHCOMP] [numeric](7, 0) NOT NULL,
[SHDESC] [char](35) NOT NULL,
[SHTYPE] [char](1) NOT NULL,
[SHAMT] [numeric](9, 2) NOT NULL,

[Code] ....

I need to remove records that have the same ID, Name, Description and Amount summary = 0, For example

SHCOMP CBLNAM SHDESC SHAMT SHTYPE

123 cust1 desc1 45 F remove
123 cust1 desc1 -45 T remove
123 cust1 desc1 45 F remove
123 cust1 desc1 -45 T remove
123 cust1 desc1 45 F

[Code] ....

Results

SHCOMP CBLNAM SHDESC SHAMT SHTYPE

123 cust1 desc1 45 F

123 cust1 desc1 -35 T

234 cust3 desc2 30 F

here is what I did but didn't work because sum is <> from 0 so is leaving all records

select SHCUST, SHDESC, ABS(SHAMT) SHAMT
into #t1
FROM #Temp
group by SHCUST, SHDESC, ABS(SHAMT)
having SUM(SHAMT)=0
order by SHCUST

delete S from #Temp S
join #t1 T on T.SHCUST = S.SHCUST and T.SHDESC = S.SHDESC
