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?

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.

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

Check Previous Row In The Table

Jul 9, 2004


Is there any way to check previous row in SQL Query?

I have a table with these column :
Audit_Time (datetime)

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.

Data Access :: Select After Check Previous Records

May 5, 2015

I have two tables. Users and records. I need to select only the users that not has lines recorded in the other table. How could I do that?


ID| Name| Access 1|Access 2|
1 | Axel   | True         |False   |
2 | Ivan  | False        |False   |
3 | Bob  | True          |False   |
4 | Sue  | False         |False   |

ID| Points| Month| Year|User_1|User_2|
1 |  2      |    5 | 2015|   2  |   1  |
2 |  5      |    5 | 2015|   2  |   1  |
3 |  1      |    5 | 2015|   3  |   1  |

Then I want to run a select in the users table, only with the users that hasn't records in the second table.

In the example, the second table has User_1 as the user who receives the points and the User_2 is the user who give the points. Then I would know what user didn't receive 'points' yet.

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


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?

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

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.

How To Sum Previous Row Values?

I need your help for my SQL query. I have a table like this

ClmA ClmB ClmType
1 | 10 | 0
2 | 20 | 0
3 | 30 | 1
4 | 40 | 0
5 | 50 | 1

And its the result that i want to get.

ClmA ClmB ClmType ClmResult
1 | 10 | 0 | 10
2 | 20 | 0 | 30
3 | 30 | 1 | 30
4 | 40 | 0 | 70
5 | 50 | 1 | 80

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.

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

[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


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] ....



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

into #t1
FROM #Temp
having SUM(SHAMT)=0

Most Effecient Way To Get Previous Row Values?

Jan 23, 2007

Wow, this board has gotten really busy lately - maybe 2007 is the year that a lot more people start using SSIS :)

Anyway my question is this: If I have an ordered set of data in the data flow and I want to add a column, lets just say "previousID" that basically has the ID value of a column from the row immediately before it - what is the most effecient way of doing that?

I've done much more complicated things with running averages, mean, etc by creating an asynchronous script transformation, pushing the data into a datatable in memory and looping through row by row using variables etc to do the calcs... but I just have this feeling that there is a "lighter, faster, easier" way for just getting previous row's value (with some special rows like first row has a null etc) than looping through a datatable row by row.

Can you push the buffer into an array (if so anyone have an example script) and use simple "n-1" logic? (ie using the array index)

Copy Values From Previous Row

Aug 26, 2006

I'm guessing this is a fairly straight forward need, but want to make sure I am using the correct set of tasks:

In the dataflow, some values I need to carry forward from the previous row, such as a balance that I need to carry forward for the current customer record. This is similar to a running total, only I am not summing anything, but just carrying over from the previous records value (assuming dataset is sorted correctly, first by customer #, then by date).

Do I need the Dervied Column transform, and use a variable to store the previous value, or is there another transform that would be better suited?

T-SQL (SS2K8) :: Set Current Row Using Values In Previous Row

Feb 25, 2015

I've tried all sorts of code i.e. cross apply, running totals, etc. Cannot get this to work. I am trying to add a previous row value but only doing it for each group.

Source records
DECLARE @tbl table (Item int, Sequence int, StartTime datetime, Duration int)
INSERT INTO @tbl (Item,Sequence,StartTime, Duration) VALUES (1,1,'2/25/2015 12:00 am',10),(1,2,null,20),(1,3, null,22),(2,1,'2/25/2015 1:00 am',15),(2,2,null,30),(2,3, null,45),(2,4, null,5)
select * from @tbl

1102/25/15 0:0010
12null 20
13null 22
2102/25/15 1:0015
22null 30
23null 45
2 4 null 5

I would like to set the start time of the next row to be equal to the previous row time + duration. I know the start time of each group of 'Items' when the 'Sequence' number = 1. The last 'duration' value in the group would be ignored.

My expected output would be:

1102/25/15 0:0010
1202/25/15 0:1020
1302/25/15 0:3022
2102/25/15 1:0015
2202/25/15 1:1530
2302/25/15 1:4545
2402/25/15 2:305

Lookup To Check Values In 13 Columns With Same Values

Mar 22, 2006


it is my first post on this forum, please be patient if i miss any important bit of information.

i am transporting data from a legacy system into mssql 2k5 using SSIS.
among those column of a dataset there are 13 columns, all necessary for operational reasons, that i need to ensure data consistance.

i believe i could do this check using the lookup data flow item, but surely there must be a way to do it in a more streamlined fashion.

since column names contain numbers to distinguish the version, eg; col01, col02, col03 .. col13.

i thought i could include the lookup within a loop and use a couple of variables to do this trick, but since i have not done it before i am asking for some sort of guidance from a guru among you folks.

please let me know if further clarification is necessary.
