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
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)
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')

I need to select a spesific record using the recordkey and then select the previous and the next record as well. (which leaves me with a recordset containing three records)
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]
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?
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?
My current code returns account_number with multiple start_date regardless of the value is same or not. However, I would like to get only the account number when the value on start_date is different within same account_number.
select acct_number count(start_date) from table_A group by acct_number, start_date having(count(start_date) > 1)
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.
file_target_ID is identity column which will repeat per files_ID
Now, i just shown Target log for file_ID 77796 see the last Target Date i want another column which returns a previous log Target date for each files beside Target date column
Like this ..
Target Date New Column 2015-09-09 00:00:00.000 2015-09-16 00:00:00.000 2015-09-16 00:00:00.000 2015-09-25 00:00:00.000 2015-09-25 00:00:00.000 New Target date after 25-9-2015
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".
Hello...i have a table that record all the reading meter....so when i change one of the reader meter data...in logical it will automatically change the normalized fields...
Reading teble ------------------- -id[PK] -meter -normalized -date when i insert new record..i just insert data about date and meter...an normalized is automated calculate using my function..the problem is..when i have data more than one...when i try insert or update or delete data...it nee to be automatically calculate back the normalized..i know this is needed the temperory table and then reinsert back..how can i solve this problem???
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.
Data from as400 imports into SQL with blank fields which is the way as400 outputs records. How can you insert previous record of data null or blank field. ex:
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.
My goal is to update the "PriorInsert" field with the "DateInserted" from the previously inserted record where the WorkOrder, MachineNo, and Operator are all in the same group.
While trying to get to the correct previous record, I wrote the query below.
P.S. The attached .txt file includes a create and insert tbl_tmp sampling.
select top 1 a.ID, a.WorkOrder, a.MachineNo, a.Operator, a.PriorInsert,
I have a table with the following structure in sql server 2005

I want to retrive previous 5 records, next 5 records and the record that meet the where condition of a select query.
When I run
select sno,add,name,city,state from app where sno=7
I want the following result
------------------------------------------ sno name add city state ------------------------------------------ 2 mark street no1 newcity newstate | 3 mark street no1 newcity newstate | 4 mark street no1 newcity newstate | -- previous 5 records 5 mark street no1 newcity newstate | 6 mark street no1 newcity newstate | 7 mark street no1 newcity newstate --- searched record 8 mark street no1 newcity newstate | 9 mark street no1 newcity newstate | 10 mark street no1 newcity newstate |--- next 5 records 11 mark street no1 newcity newstate | 12 mark street no1 newcity newstate | ----------------------------------------
if there is a method to get the above result set, kindly post the query.
I use select @@identity to return @@identity from my store procedure,but I could not retrive it from my Visual basic code, like variable=oRS.fields.item(0).value, it always says item can not be found....
