SQL 2012 :: Group By On Consecutive Records?
Apr 4, 2015
Problem 1: I have the following table which shows the location of a person at 1 hour intervals
IdEntityIDEntityNameLocationIDTimexdelta
11MickeyClub house03001
21MickeyClub house04001
31MickeyPark05002
41MickeyMinnies Boutique06003
51MickeyMinnies Boutique07003
61MickeyClub house08004
71MickeyClub house09004
81MickeyPark10005
91MickeyClub house11006
The delta increments by +1 every time the location changes.
I would like to return an aggregate grouped by delta as per example below.
EntityNameLocationIDStartTimeEndTime
MickeyClub house03000500
MickeyPark05000600
MickeyMinnies Boutique06000800
MickeyClub house08001000
MickeyPark10001100
MickeyClub house11001200
I am using the following query (which works fine):
select
min(timex) as start_date
,end_date
,entityid
,entityname
,locationid
[code]....
However I would like to not use the delta (it takes effort to calculate and populate it); instead I am wondering if there is any way to calculate it as part / whilst running the query.
Problem 2:I have the following table which shows the location of different people at 1 hour intervals
IdEntityIDEntityNameLocationIDTimexDelta
11MickeyClub house09001
21MickeyClub house10001
31MickeyPark11002
42DonaldClub house09001
52DonaldPark10002
62DonaldPark11002
73GoofyPark09001
83GoofyClub house10002
93GoofyPark11003
I would like to return an aggregate grouped by person and location.
For example
EntityIDEntityNameLocationIDStartTimeEndTime
1MickeyClub house09001100
1MickeyPark11001200
2DonaldClub house09001000
2DonaldPark10001200
3GoofyPark09001000
3GoofyClub house10001100
3GoofyPark11001200
What modifications do I need to the above query (Problem 1)?

I have a data set that looks something like like this:
Row# Data
1 A
2 B
3 B
4 A
5 B
6 B
7 A
8 A
9 A
I need wanting to assign a group ID to the data based on consecutive values. Here's what I need my data to look like:
Row# Data GroupID
1 A 1
2 B 2
3 B 2
4 A 3
5 B 4
6 B 4
7 A 5
8 A 5
9 A 5
You'll notice that there are only two values in DATA but whenever there is a flip between them, the GroupID increments.

I've inherited a table of members that has the following structure:
CREATE TABLE [dbo].[dimMember](
[dimMemberId] [int] IDENTITY(1,1) NOT NULL,
[dimSourceSystemId] [int] NOT NULL CONSTRAINT [DF_dimMember_dimSourceSystemId] DEFAULT ((-1)),
[MemberCode] [nvarchar](50) NOT NULL,
[FirstName] [nvarchar](250) NOT NULL,
[LastName] [nvarchar](250) NOT NULL,
[Code] ....
Based on the way the data loads into the table there's a possibility of some records being near duplicates of each other. For example, we can have a member that has records that have the same first name, last name, SSN, but different addresses, membercodes, subscribercode etc... This can happen in pretty much any variation thereof.
What I want to do, is add a new column and use that to group the similar records under based on comparing on several columns. By this I mean, if a member matches 4 of the 7 values below with another member, we would group these:
First Name (1st 3 characters)
Last Name
DOB
CurrentAddress1
MemberCode
SSN
SubscriberCode
I'm at a loss of how to structure the SQL to update the new column in the table.

This is peculiar.
I need to delete one of duplicate records only if they occurs consecutively.
eg.
1. 232
2. 232

4. 567
5. 232
Here only the first record has to be delete. Kindly help me out.

I am fairly new to SQl and PHP and have a question. I have a database that we enter in when a person buys a season ticket for our baseball team. I want to check and see who bought in 2013 but has not yet bought in 2014. How do I do that?
THID is the ticket holder ID and there is a year. I can do the select * from Passes where Year = '2014' and get everyone who has bought in 2014. How do I compare that with the 2013 and show people who have not bought yet in 2014?
Example entry:
THID PassType Year
15 2 2013
21 1 2013
10 1 2013
21 1 2014
With this - Ticket holder 21 has bought in both years so I wouldn't want his name to come up. I would want to see that ticket holders 15 and 10 haven't yet bought in 2014.

We have customer accounts that we measure usage. We want to run a report for all customers whose current usage is 0 and a count of how many months it has been zero consecutively. Here is an example.
declare @YourTable table (
CustomerID int,
ReadDate datetime,
usage int
)
insert into @YourTable select 1,' 1 mar 2014',0
insert into @YourTable select 1,' 1 feb 2014',0

This should return

How to create a row number for a consecutive action. Example: I have a listing of people who have either completed a goal or not. I need to count by person the number of consecutively missed goals.
My sql table is this:
PersonId, GoalDate, GoalStatus (holds completed or missed)
My first thought was to use the rownumber function however that doesn’t work because someone could complete a goal, miss a goal, then complete one and when they complete a goal after a missed goal the count has to start over.

I usually do this through Access so I'm not too familiar with the string functions in SQL. My question is, how do you remove characters from the middle of a string?
Ex:
String value is 10 characters long.
The string value is X000001250.
The end result should look like, X1250.
I've tried mixing/matching multiple string functions with no success. The only solution I have come up with removes ALL of the zeros, including the tailing zero. The goal is to only remove the consecutive zeroes in the middle of the string.

I have a table like this.
CREATE TABLE Table1
([S_ID] varchar(7), [S_ACTV_CODE] varchar(4), [S_USER] varchar(5), [S_DATETIME] varchar(19), [S_ACT_IND] int)
;
INSERT INTO Table1
([S_ID], [S_ACTV_CODE], [S_USER], [S_DATETIME], [S_ACT_IND])
VALUES
('AAA-111', NULL, 'USER1', '2015-06-15 00:21:06', 0),
('AAA-111', '2', 'USER1', '2015-06-15 00:21:07', 0),
[code]....
Basically I want to calculate the time spent by S_Users on a particular S_ACTV_CODE:
- S_ACTV_CODE_PREV means the previous active records.
- S_START_TIME is the time of S_DATETIME when a S_ACTV_CODE starts
- S_END_TIME is the time before a S_ACTV_CODE changes to another S_ACTV_CODE
- For the first record, S_ACTV_CODE is null, so there is no S_ACTV_CODE_PREV, so S_ACTV_CODE_PREV is NULL
- For the second record S_ACTV_CODE has some value, but S_ACTV_CODE_PREV is NULL for first record. So second record S_ACTV_CODE_PREV is also NULL
- For the last record (means S_ACTV_IND = 1), the user is currently working on it and S_ACTV_CODE is not changed. So S_END_TIME is a open time and we want to keep it as NULL
So the result should be as below:
S_ID S_ACTV_CODE_PREV S_ACTV_CODE_CURR S_USER S_START_TIME
S_END_TIME TIME_SPENT (in Sec)
AAA-111 NULL NULL USER1 2015-06-15 00:21:06
2015-06-15 00:21:07 1
AAA-111 NULL 2 USER1 2015-06-15 00:21:07
2015-06-17 03:20:33 183566
AAA-111 2 4 USER2 2015-06-17 03:20:33
[code]....

I have a table full of service invoice records. Some of the invoices are continuous, meaning that there may be an invoice from 01-16-2015 through the end of that month, but then another invoice that starts on feb 1 and goes for 6 months.
I want to only pull the most recent. Keep in mind that there may be other invoices in the same table for a different period. An example might be:
FromDate ToDate Customer Number Contract Number
02/01/2015 07/31/2015 2555 456
01/15/2015 01/31/2015 2555 456
04/01/2013 09/30/2015 2555 123
03/13/2013 03/31/2013 2555 123
From this table, I would like a query that would give me this result:
01/15/2015 07/31/2015 2555 456
03/13/2013 09/30/2015 2555 123
There will likely be more than just 2 consecutive records per contract number.

I'd like to ask how you would get the OUTPUT below from the TABLE below:
TABLE:
id category
1 A
2 C
3 A
4 A
5 B
6 C
7 B
OUTPUT:
category count id's
A 3 1,3,4
B 2 5,7
C 2 2,6
The code would go something like:
Select category, count(*), .... as id's
from TABLE
group by category
I just need to find that .... part.

I'm having a fight with Reporting Services at the minute when trying to compute an average at the row group level for a value summed in a column group.I have the following column groups:
Year
Month
Date
And the following row groups:
Region
Product
SubType (hidden, data at the date level is summed to Product)
At the moment I'm computing the average for SubType for each Date at the Product level (giving a decimal value), so for each day I end up with a nice average, that works. However I am unable to average that average over the whole Year for a Product. The issue being that I'm trying to combine Row Groups (Product) and Column Groups (Date/Year)

Graeme Brown|2012-02-23 14:05:00|2012-02-23 15:40:00|2052|1111|AK1/4/PI2
They are grouped on the last column [DESC].
I want to get;
NAME| RUN START| RUN END| LK1| LK2| DESC
Graeme Brown| 2012-02-23 07:20:00| 2012-02-23 15:40:00| 2213| 1111| AK1/4/PI2
So what it needs to do is combine the ;
earliest RUN START and corresponding LK1 with
latest RUN END and corresponding LK2.
I've tried creating temp tables with the mins and maxs - but then I can't combine them with the LK1 and Lk2 fields...

I need to write a select query that will retrieve any GroupID in which every record has an Enabled value of 1.In the example I've provided, only GroupID 1 and 3 will be returned since GroupID 2 has a record with an Enabled value of 0.What would be the most efficient way to write such a query?

Hi all, I am relatively new to sql and have an issue I am trying to solve. I have a table with several records with the same id:
id amount date
-- ------ ------
1 100 01/01/2006
1 2000 06/01/2005
2 200 01/01/2005
2 500 06/01/2007
how would I get the data for the record with the newest date?
So I would return:
id amount date
-- ------ ----------
1 100 01/01/2006
2 500 06/01/2007
Thanks in advance for the help.

Hi,
I've a problem with the following stored procedure Select . It does compile and run, but doesn't return the sorted result I wanted, which was to have the records from tblPieces (alias Pcs) sorted by (in order) Pcs.fkBatchId, Pcs.fkProfileCode, Pcs.Colour. What happens instead, I think, is that the correct records are selected, but in the record creation order. CREATE PROCEDURE dbo.LoadOneBatch
(
@BatchId int, -- the pkBatchId of the batch required
@OnlyNew bit -- If true, only consider batches that haven't ever been loaded.
)
AS
SET NOCOUNT OFF
SELECT Bat.pkBatchId,
Pcs.*
FROM tblBatches AS Bat
JOIN (
SELECT Bat1.pkBatchId,
Pcs1.fkProfileCode,
Pcs1.Colour
FROM tblBatches AS Bat1
JOIN tblPieces AS Pcs1 ON Pcs1.fkBatchId = Bat1.pkBatchId
WHERE Bat1.pkBatchId = @BatchId
GROUP BY Bat1.pkBatchId, Pcs1.fkProfileCode, Pcs1.Colour
) SubQ ON SubQ.pkBatchId = Bat.pkBatchId
JOIN tblPieces AS Pcs ON Pcs.fkBatchId = Bat.pkBatchId
WHERE (@OnlyNew = 1 And Bat.IsLoaded = 0 And
Bat.IsCompleted = 0 And Bat.pkBatchId = @BatchId) Or
(@OnlyNew = 0 And Bat.pkBatchId = @BatchId)
GO
EXEC LoadOneBatch @BatchId = 1, @OnlyNew = 0
The DDL for the two tables is:CREATE TABLE [tblBatches](
[Stamp] timestamp NOT NULL,
[pkBatchId] int IDENTITY(1,1) NOT NULL,
[BatchNo] varchar(50) NULL,
[SubmitTime] [datetime] NULL,
[FinishTime] [datetime] NULL,
[IsLoaded] bit NULL,
[IsCompleted] bit NULL,
PRIMARY KEY ( [pkBatchId] ASC )
)
CREATE TABLE [tblPieces](
[Stamp] timestamp NOT NULL,
[pkPieceId] int IDENTITY(1,1) NOT NULL,
[fkBarId] int NULL,
[fkBatchId] int NULL,
[PieceNo] varchar(12) NOT NULL,
[Descrip] varchar(48) NULL,
[Position] real NULL,
[LeadPrep] char(1) NOT NULL,
[TailPrep] char(1) NOT NULL,
[Length] real NOT NULL,
[fkProfileCode] varchar(10) NOT NULL,
[Colour] varchar(5) NOT NULL,
PRIMARY KEY ( [pkPieceId] ASC )
)
The data records output are roughly:pkBatchId Stamp pkPieceIdfkBarIdfkBatchIdPieceNo Descrip PositionLeadPrepTailPrepLengthfkProfileCodeColour

I'm bulk loading employees into an etl table, each employee has a unique ID number, but they have multiple records in the data. Sometimes their name or birthdate will change and I want to identify those records and only insert the newest version into production. I can do this with a series of temp tables, but I'm sure there's a better way. The SQL below updates the etl table with the flag I want to mark the inserts, but it seems convoluted. (Jon's birthday changes, Jane's birthday changes, Bill's gender changes, Amy nothing changes(I handle those inserts later))
DECLARE @Records TABLE(
firstname varchar(50), lastname varchar(50), birthdate date, sex char(1), IDNum varchar(15), moddate date, opflag char(1))
INSERT INTO @Records
VALUES
('JON','SMITH','20000101','M','12345','20140101','I'),
('JON','SMITH','20000101','M','12345','20140201','I'),
[code]....

I have a table with 5 columns, let say ID,PersionID, Date, Type,Qty and source data looks like this
ID PersonID Date Type Qty
1 1 01/01/2011 Accept 5
2 1 01/01/2011 Accept 5
3 2 02/01/2010 Accept 10
4 2 02/01/2010 Deny 20
5 3 02/01/2012 Accept 15
[Code] .....
Output should look like this..look for only Type=Accept until deny is reached. After Deny,if there is a Accept ignore it.
ID PersonID Date Type Qty
1 1 01/01/2011 Accept 5 (show only one Accept row=1 becoz Type is Accept and date is same,Qtyis
same)
3 2 02/01/2010 Accept 10 (show Accept row=3,ignore deny row)
5 3 02/01/2012 Accept 15 (show Accept row=5)
6 4 05/05/2012 Accept 25 (show Accept rows=6,7 and ignore Deny & Accept rows = 8,9)
7 4 07/08/2012 Accept 20
11 6 01/01/2011 Accept 5 (show Accept rows=11,12 because Qty is different)
12 6 01/01/2011 Accept 15
Create Sample Table (ID int null, PersonID Int null, Date Datetime null , Type varchar(10) null, Qty int null)
Insert into sample values (1 ,1,'01/01/2011','Accept',5),
(2,1,'01/01/2011','Accept',5),
(3,2,'02/01/2010','Accept',10),
(4,2,'02/01/2010','Deny',20),
(5,3,'02/01/2012','Accept',15),
(6,4,'05/05/2012','Accept',25),
(7,4,'07/08/2012','Accept',20),
(8,4,'07/08/2012','Deny',5),
(9,4,'09/23/2012','Accept',23),
(10,5,'09/08/2012','Deny',12),
(11,6,'01/01/2011','Accept',5),
(12,6,'01/01/2011','Accept',15)

Hi all,
I have a report which is grouped by a field called R_ID, which gives me a list of records for each R_ID. So here is the thing, I want to get only top 3 records for each R_ID. Is there any way to do this thing in the report level. I tried it from the query level, but the result is not like what I wanted.
Please let me know if some body has any idea.
Thx.

I am fairly new to transact SQL and I am having difficulty retrieving the set of records I require given the data shown below. I want to be able to filter the records just to return the records that have the minimum securityorder for each unique secsyscode. I suspect I need to use min or group by to achieve the desired affect but cannot seem to get it right
any help would be appreciated
eg in the following
secsyscode, securitytypecode and securityorder are integers and securityCode is a char(16).

I have a pretty complex query that returns three records. For simplicity sake, the results can be simulated with this query:
Select 5 AS InternalAuditTeamEmployeeID, 1 as InternalAuditTeamID
UNION ALL
Select 11, 2
UNION ALL
Select 14, 3;
I want to take this result and update the Flag field to true in my table tblInternalAuditTeamEmployee (CREATE statement below) for any InternalAuditTeamEmployeeID that is less than or equal to the ones in the results above, but by group. My results would look something like this using the data below and the results above.
InternalAuditTeamEmployeeIDInternalAuditTeamIDEmployeeIDFlag
1 1 619 1
218581
316041
425181
517161
639661
711910

1012340
1129541
1228910
1329500
143321
1539450
I was thinking I could somehow use ROW_NUMBER(PARTITION BY InternalAuditTeamID ORDER BY InternalAuditTeamEmployeeID DESC), but not sure how to get the results of "WHERE <= InternalAuditTeamEmployeeID For each particular group".
CREATE TABLE STATEMENT:
CREATE TABLE [tblInternalAuditTeamEmployee](
[InternalAuditTeamEmployeeID] [int] IDENTITY(1,1) NOT NULL,
[InternalAuditTeamID] [int] NOT NULL,
[EmployeeID] [int] NOT NULL,
[Code] ......

I have a table T (a1, ..., an, time, id). I need to select those rows that have different id (GROUP BY id), and from each "id group" the row that has the latest field 'time'. Something like SELECT a1, ..., an, time, id ORDER BY time DESC GROUP BY id. This is the wrong syntax and I don't know how to handle this.

Looking to see if thier is a better way to find the last record entered in a group of records.
What I'm doing now is finding the max for the secound column and then doing a sub query to find the max of the third column having the second columns equal.
Table example using simplied data.
PolId
CoveragId
EffDate
Status
Limit1

The parent program addes a row every time the data is changed. To make things worst; the records arn't always in sqenal order like the above table and some time edits the row instead.
The current query returns a single value. from a single table.
Current code used in the select protion on a larger query. bpi = basicpolicyInformation.
( Select c1.limit1
From AFW_Coverage as c1
Where c1.PolId=bpi.PolId
and c1.CoverageId = (select max(CoverageId) as CoverageId
From AFW_Coverage as c
where c.PolId = c1.PolId
and c.CoverageCode = 'Dwelling'
and status <> 'D'
)
and c1.effDate = (select max(Effdate) as Effdate
From AFW_Coverage as c
where c.PolId = c1.PolId
and c.CoverageID = c1.CoverageId
)
Explain the current code. It uses the two sub queries to find the correct record ID that has the data needed.
