Generating Unique Sequence Number
Jul 19, 2000Is there wa way to generate unique sequence numbers in SQL server?
(just like the way it is in Oracle i.e. seqeuence and then use nextval)

Generating Sequence Number
Aug 29, 2001Hello,
I need to know how to generating a sequence number, for example, from 300,000 to 900,000 without skipping any number due to failure. For example, if user 1 request a number then he/she will get 300000 in a transaction. User 2 will get 300001. How ever user 1's transaction fails, then the next request should get 300000. Is it possible to do this in SQL2K? If so, how do I create a table that and stored procedure that can do this.
Thank you so much.

Sequence Number Generating With A Twist
Apr 9, 2008:eek:
I'm having a brain not functioning day - well who am I kidding - more like a year :rolleyes:
I need some help with some sequence numbering and cannot even get my head around the logic I want to use, let alone the actual code.
I have a dataset with 3 fields:
Area
ID
RefNo
This table contains a list of employee ID's by Area and each employee has a RefNo (counter) in each area.
The data comes from 2 different sources and is combined in this table. Some employees had no RefNo already assigned to them so I have entered their RefNo as 10000 in order to ensure they are sorted at the bottom of the list.
The ID's that have RefNo's have to keep the one they have. Therefore, I need to create RefNo's for the ones that currently have RefNo 10000.
These numbers I create have to follow on from the highest RefNo for the Area.
For example:
Area ID RefNo
A Z 1
A Y 2
A X 3
A W 10000
A V 10000
B N 1
B O 10000
B P 10000
So, for Area A, ID's W and V would have to be assigned RefNo 4 and 5, and for Area B, ID's O and P would have to be assigned RefNo 2 and 3.
Hope this makes sense to all.
BTW, am using SQL 2000 at the moment.
Thanks in advance for any help!

Generating Unique Id Strings
May 25, 2004Hi
I want to generate a unique record number in the following format
Company initials/year/Counter/RecordType (e.g. SDS/04/00123/WB)
Could someone recommend how I go about generating this number?
Should I create a separate table with columns for each section of the number and concantenate the columns in ID field of the actual table?
... or should I just create a stored procedure to generate the number each time?
... or should I do something completely different?

Generating Unique No Based On Certain Data
Oct 3, 2007Hi,
I have the following tables :
Code Block
Create Table #Request ( [requestid] int , [customername] Varchar(30) , [stateno] nvarchar(5) , [cityno] int , Callid int, UniqueNo int);
Create Table #Call(Callid int,Calltype int,callDetailid int ) // CallType 1=New 2=Change 3=Delete
Create Table #CallDetail(callDetailId int,empid int)
The tables are populated in the following order: One row for CallDetail, One for Call and one for Request and so on
I have to generate a UniqueNo - Per empid, Per StateNo, Per CityNo, Per CallType and insert into #Request table along with the other data. How do I do this?

Oct 11, 2007I have a procedure which updates a sequence number in a table such as the one below.
Seq Sequence_Id

NextNum 1
This is the procedure ...
create procedure DBO.MIG_SYS_NEXTVAL(@sequence varchar(10), @sequence_id int)

@sequence_id = sequence_id = sequence_id + 1

The purpose of this is to generate a sequential number each time the procedure is called. This number would then be used in a number of different tables to allocate a unique id so that the id is unique across the different tables.
1). What is the most efficient way of allocating these unique ids? The tables that I plan to update will already be populated with data.
2). How would I call the above procedure from an UPDATE statement?

SELECT @abrid = @ay + @ddo + right('0000' + rtrim(convert(char(4), @seq_no)), 4)

AY,
REQUESTOR,

DESCRIPTION,
@status
FROM dbo.Temp_ABR_HDR
SELECT @id = @@identity

GO
ABRID gets inserted as a <NULL> value. I can't figure out why? If I comment out the following then ABRID will insert without the sequence number:
CREATE PROCEDURE dbo.ABR_HDR_INSERT
@id int output,
@status int,
@mode int,

@mode,
DDO,
AY,
REQUESTOR,
DT,
SUBJECT,
DESCRIPTION,
@status
FROM dbo.Temp_ABR_HDR
SELECT @id = @@identity
return @id
GO
So, the code that sets the sequence number is what is causing the <NULL> value.
Any help is appreciated.

View 3 Replies View RelatedGenerating Membership Number
Jan 20, 2005Hi all,
I have a question about generating membership numbers on the fly when someone registers to my website.
Rather than using the auto increment field as a membership number, I would rather keep it as just as the ID for the record and I would like to have a seperate membership number that looks something similar to this...
SR357324J
This will then stay with them for the lifetime of their membership and be on their printed loyalty card.
My questions are...
1) Is there a 'good practice' for membership number format and generation?
2) If this was used as a unique field, is there a degradation in performance when looking up records due to it being alphanumeric.
I may be well off base here, however these are my thoughts so far and your opinion/help is greatly appreciated.
Thanks for your contribution.

Sequence Number Generation
Feb 3, 2005Does anyone know an efficient method for generating a sequence number in the following form?
Starting with 2 columns
1 2
----
A X
A Y
B X
B Y
B Z
C X
I want to then generate a third column as follows:
1 2 3
-------
A X 1
A Y 2
B X 1
B Y 2
B Z 3
C X 1
The purpose being so that I can easily identify the previous row within a Column1 group. So given column1=A and column2=Y I know that the previous row is Column3 - 1 where column1 = A. Therefore I will be able to join to the previous result of any row within any group quickly for future calculations.
Any ideas? Thanks.

Auto Number Sequence
Oct 6, 2006How can I create a number sequence starting at a certain number and continue on for the number of records I have.
For example I have 3000 records in my table and a field named I created called RecordId which I'd like to start at number 1 and goto 3000 (or maybe even start at 9000 and goto 12000 or however many records there are).
In my pseudo SQL code Im guessing it would be something like...
select * from Incident
update Incident
set RecordId( i=9000; i<=Number of Records in Table; i++)
Whats the easiest way to do this?
