SQL Server 2014 :: Getting Unique Number For Groups Of Records?

Aug 6, 2014

I'm trying to do the following and haven't been able to figure it out.

Say there's a table with these records:

Col1 Col2 Col3
a b c
a b c
a b d
e f g
e f g

I want to generate a number that represents the groups of columns like this:

Col1 Col2 Col3 MyNumber
a b c 1
a b c 1
a b d 2
e f g 3
e f g 3

So that each grouping gets its own identifier. I've tried this:

SELECT Col1, Col2, Col3
row_number() OVER (PARTITION BY Col1, Col2, Col3
ORDER BY Col1, Col2, Col3) AS MyNumber
FROM MyTable

But I get this:

Col1 Col2 Col3 MyNumber
a b c 1
a b c 2
a b d 1
e f g 1
e f g 2

Unique Transaction Number

Oct 13, 2004

As part of the credit card process I have to supply a unique transaction id.

I thought the best way to do this would be to have a file which just holds a number which I grab and increment each time some one registers. Then if everyting is alright I will write the user's details a long with the transaction id to the User file.

My question is, if two people try to register and both try to grab the next number from the file at the same time, what will happen. Will one get a record lock message, or will it wait untill the other one has finished, or could two people end up with the same number under these circumstances?

I am of course open to suggestions on the best way of approaching this, but please bare in mind that I am only using Web Matrix.

Thanks

Mark

Unique Confirmation Number

Jan 23, 2008

Hi to alll of you, i'm working in a project to save cars information, when the user who adds on the new record enter all the data, this will need to be printed with a particulary number, which needs to be unique, (lets take a passport number as an example) this generated number will takes some info from the filling fields, for example:

Cars Brand: BMW (catalog number: 120)
Cars Model: 325 (catalog number: 30)
Year: 2008 (catalog number: 18)

So the unique certification number will takes from the catalog numbers * 20 / 5 for example for cars Brand
for Cars Modelo: catalog number *3 + 15


CERTIFICATE NUMBER: 480-105

I'm not sure if this is possible.

I will realy thanks for your help in this issue.
Best Regards

Gian

New Unique Number In History Table

May 23, 2008

Hello,
I am using SQL Server 2005 and am having trouble with making a history table like mentioned in my earlier thread:

http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=102811

This is the table "People" I have created:

|PersonId (PK)|DateFrom (PK)|DateTo|PersonName|Other Attributes....

Each change to a person's attributes results in a new row formed with the same PersonId as in the row with old attributes and the Date these new attributes are valid (DateFrom). So as shown above the Primary Key is a combination of the PersonId and DateFrom as a change to a person's attributes should never happen at the same time twice.

My problem is when I want to create a new person, how do I get a new unique id? Ideally I want the a new incremented id, so that all peoples' ids are in a sequential order.

As always, thanks for the help!

Generate Random And Unique Number Within Sql ?

Dec 11, 2007

I need to generate a random 10 digit alphanumeric string that is also unique within a table. My application will be calling a stored procedure to insert this number into the table. This number will be associated with a id from another table. Is it better to generate the random number within sql (and perform the lookup at the same time), then just pass the number back to the calling application ?

If the calling application generates the number, it will also need to make a call to check if its unique. So im thinking it would be best to simply have sql generate this random number, check the number against the table and then insert the new record.

thoughts ?

Transact SQL :: Set Unique Random Number

Dec 1, 2015

Lets say we have a table (tblProducts)

ID   Item             RandomNumber
-------------------------------------------
1    JEANS                      1234567
2    SHIRT                    72813550
3    HOOD                             Null
4    TROUSER               72191839
5    BLAZER                              0

I want to perform a query so that SQL should look for RandomNumber Values and set a Unique Random Number Where RandomNumber Value is Null or 0.So I have got a solution as one of the MSDN Member shared the below query

select id,item,RandomNumber=Case when RandomNumber=0 then (select floor(rand()*100000000-1))
when RandomNumber is null then (select floor(rand()*100000000-1))
else RandomNumber end from tblProducts

So, can you all confirm me, that performing this query ensures that if a Value is assigned to one of the Item in RandomNumber Column, that value will not be assignend to any other Item in RandoNumberColumn.

Re-populate A Unique Number Into Multiple Fields

Oct 14, 2004

What I need to do is re-populate a unique number into multiple fields,

Let me explain, An employee can appear in the first table only once but can be in the second table multiple times with multiple employee numbers .There is a field called TFN that is unique and we are using it to create a unique id called KRid so what I have done is created 2 tables namely TEST_TBL and TEST2_TBL . In TEST_TBL I am populating a KRid with a unique no being produced by the TFN field only once i.e 12345 being the resulting unique id number. If an employee has 2 employee numbers i.e empno 1 and empno 1000,only employee no 1 will have the unique KRid created but nothing for 1000 because the record already exists , so what has me stumped is that the TFN for employee empno 1 and the TFN for empno 1000 are the same. How do I get the KRid (12345 from empno 1) to populate empno 1000 in TEST2_TBL , The second table has all records in so I can group the second table by TFN id but how do I populate employee 1000 in the second table with the KRid 12345.


Please help!!!!! Below are how the tables are set up and an example of the result.

TABLE 1

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[TEST_TBL]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[TEST_TBL]
GO

CREATE TABLE [dbo].[TEST_TBL] (
[Empl_Num] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Surname] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[First_Name] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Mid_Name] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Hours_Day] [numeric](18, 2) NULL ,
[Hours_Wk] [numeric](18, 2) NULL ,
[KR_ID] [bigint] IDENTITY (1, 1) NOT NULL ,
[TFN] [char] (32) COLLATE Latin1_General_CI_AS NULL ,
[Date_Term] [datetime] NULL ,
[Empl_Type] [int] NULL ,
[Cost_Centre] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Empl_Status] [int] NULL
) ON [PRIMARY]
GO

TABLE 2

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[TEST2_TBL]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[TEST2_TBL]
GO

CREATE TABLE [dbo].[TEST2_TBL] (
[EmpNumber] [char] (32) COLLATE Latin1_General_CI_AS NULL ,
[TFN] [char] (32) COLLATE Latin1_General_CI_AS NULL ,
[KR_ID] [char] (10) COLLATE Latin1_General_CI_AS NULL ,
[EmpStatus] [int] NULL ,
[EmpType] [int] NULL ,
[CommonName] [char] (32) COLLATE Latin1_General_CI_AS NULL
) ON [PRIMARY]
GO

Query goes as follows for table 1:

SELECT NPE000.EmpNumber, NPET00.RecordStatus, NPE000.KR_ID, NPE000.Surname, NPE000.FirstName, NPE000.SecondName, NPE000.Class, NPE000.DateEmployed, NPE000.DateOfBirth, NPE000.HoursPerDay, NPE000.HoursPerWeek, NPE000.PassportNo, NPE000.AwardCode, NPE000.EmailPayslipTo, NPE000.Location, NPE000.Grade, NPE000.DateTerminated, NPE000.EmploymentType, NPE000.DistCode, NPE000.EmpStatus, NPET00.TaxRefNo FROM NPE000 NPE000, NPET00 NPET00 WHERE NPET00.RecordStatus = 0 and NPET00.TaxRefNo <> ' 111111111' and NPET00.TaxRefNo <> ' 000000000' AND LENGTH(NPET00.TaxRefNo) >= 9 AND LENGTH(NPE000.KR_ID) >= 0 AND NPE000.EmpNumber = NPET00.EmpNumber


Query goes as follows for table 2:

SELECT NPE000.EmpNumber, NPE000.FirstName, NPE000.Surname, NPE000.Class, NPE000.Location, NPE000.EmploymentType, NPE000.EmpStatus, NPET00.TaxRefNo, NPE000.Paypoint, NPE000.KR_ID, FROM NPE000, NPET00 WHERE Recordstatus = 0 and (EmploymentType = 1 AND EmpStatus = 1 AND NPE000.EmpNumber = NPET00.EmpNumber


From this you can see that in table 1 it will only create 1 KR_ID for only one employee number but in table 2 I am bringing through all employee records. In table 2 I can group by NPET00.TaxRefNo which will bring all NPET00.TaxRefNo's togeather. From that I would like to populate the other employee numbers with the unique KR_ID.

Example:Table 1

000001,Jackson,James,Sam,7.6,38,12345,475431212


Example:Table 2

000001,Jackson,James,Sam,7.6,38,12345,475431212
001000,Jackson,James,Sam,7.6,38,,475431212

I hope this helps

Thanks in advance

To Get An Unique Sequence Number (record Locking)

Aug 27, 2007

can someone pls show me a way to get an unique sequence at below senario:

PC1 & PC2 using their own local client progam to access to Database Server at SERVER1.
In the SERVER1, there is a table SEQUENCE in a database DATABASE1.
And the table's structure of SEQUENCE are SeqType & SeqNo.
Here is the sample data:

SeqType SeqNo
Invoice 100
DeliveryOrder 200

Now, how to prevent PC1 & PC2 to get a same Invoice No. if they request the Invoice No. at the same time?
Is it possible to lock the record Invoice when i perform a SELECT statement, then i update the Invoice to 101, lastly release the lock for Invoice?

pls advise. thanks.

Sequencial, Unique Number Tied To Header, Locking Q?

Sep 23, 2006

I have a situation where for a given customer, their invoices need to be sequentially numbered, without gaps.

Customer A Invoice 1,2,3,4 ...
A-1
A-2
A-3
A-4

Customer B:
B-1
B-2

etc.

The issue is 2 people creating an invoice for the same customer at the same time. Currently I don't assign the Invoice number until the user hits 'Save'. At that time I query for max(invoiceno) against the customer key and simply add 1. it's the last operation prior to saving against the backend.

If 2 users hit Save at the exact time, I'm getting the same (duplicated) Invoice Number.

What suggestions/techniques do you have to resolve this? Would "locking" of the customer record and storing the last highest invoice there play a part?

Thanks,

Peter

Select Unique Phone Number Contacts For Same Ranked Values From The Set

Apr 30, 2015

Below is my sample data. I can't figure out how to select Unique phonenumber contacts for the same Ranked values from the set.

Basically the table is a mix of contactIDs. Some of them have duplicate phone numbers and through a separate mechanism we have ranked them.

It's easier then to pull out max(ranked) CLI_Numbers and their counterpart contactID(s). But I am also getting 2 or more records where the rank happens to be the same. I don't want that. Any one of the contactID will do for me.

The table has also same cliNumbers with different rank values, which are then correctly being picked up in the query below.

Note: ContactId is a unique value for each person in the table.
RecordID is simply RowID.

( I have attempted to populate a sample data suited for this forum - not sure how it comes out on the browser)

if object_id('tempdb..#MyData') is not null
drop table #MyData
create table #MyData
(
RecordID int,
contactID int,
forename varchar(25),
surname varchar(25),

[Code] ....

This is my query attempt

With RankedmobileDuplicateSet
as(
select cliNumber, max(ranked_value) as ranked_max_value
from #temp_UK_mobiledata
group by cliNumber)

[Code] .....

What Is The Difference Between A UNIQUE INDEX And A UNIQUE CONSTRAINT?

A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.

Hi everyone,
I need urgent help to resolve this issue...
As far as the performance goes which one is better..
Unique Index(col1, col2) OR Unique constraint(col1, col2) ?
Unique constraint automatically adds a unique index
and unique index takes care of uniqueness then whats the use of unique constraint ?

Which one do one use ?

How To Select Unique Row When Entire Row Not Unique?

Mar 12, 2008

I am having a problem trying to figure out the best way to get the results I need. I have a table of part numbers that is joined with a table of notes. The table of notes is specific to the part number and user. A row in the notes table is only created if the user has entered notes on that part number. I need to create a search that grabs all matches on a keyword and returns the records. The problem is that it currently returns a row from the parts table with no notes and a separate row with the notes included if they had created an entry. It seems like this should be easy but it eludes me today.
Here is the code



Code Snippet
create procedure SearchPartKeyword
(
@Keyword varchar(250) = null,
@Universal_Id varchar(10) = null
)
as
select p.PartNumber, p.Description, p.ServiceOrderable, n.MyNotes, p.LargestAssembly, p.DMM,
p.Legacy, p.Folder, p.Printer
from Parts p inner join notes n on p.PartNumber = n.Identifier
where n.Universal_ID = @Universal_ID and p.Description like @Keyword
union
select p.PartNumber, p.Description, p.ServiceOrderable, '' as MyNotes, p.LargestAssembly,
p.DMM, p.Legacy, p.Folder, p.Printer
from Parts p
where p.Description like @Keyword





and the results:
PartNo Description SO Notes LA DMM Legacy Folder Printer
de90008 MAIN BOARD 1 DGF1 114688 0 0 0
de90008 MAIN BOARD 1 I love this part Really I do DGF1 114688 0 0 0

This could return multiple part numbers and If they have entered notes I want the row with the notes

Thank You
