Hallo,
Hot to get unique, sequential number during execution
of stored procedure ?
I can create table with autoincrement column,
add record, get ident_current and delete record
each time i need the number.
However its not elegant i guess.
best regards

Is 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)
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.
I have created a view based on joining 3 tables, however, it is not possible to have a unique field in the view which I must need it and I must create index on some other fields. Is there any way to create sequence number or uniqie field in mssql view.

I'm currently using Oracle sequence and doingsomething like:select seq.nextval from dual;Then I do my insert into 3 different table all using the same uniqueID.I can't use the @@identity function because my application uses aconnection pool and it's not garanteed that a connection won't be usedby another request so under a lot of load there could be major problemsand this doens't work:insert into <table>;select @@identity;This doesn't work because the select @@identity might give me the valueof an insert from someone else's request.Thanks,Brent
View 4 Replies View RelatedI 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)
as
begin
update mig_sys_sequences
set
@sequence_id = sequence_id = sequence_id + 1
where
seq = 'CSN'
return(@sequence_id)
end
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?
Many thanks,
Fred

I have the following stored procedure:
CREATE PROCEDURE dbo.ABR_HDR_INSERT
@id int output,
@status int,
@mode int,
@sessid varchar(100)
AS
declare @ay char(4)
declare @ddo char(4)
declare @abrid varchar(50)
declare @seq_no int
SELECT @ddo = a.DDO_DSCR_SHORT
FROM dbo.DIM_DDO a
JOIN dbo.Temp_ABR_HDR b
ON a.DDO_ID = b.DDO
WHERE b.SESSIONID = @sessid
SELECT @ay = AY
FROM dbo.Temp_ABR_HDR
WHERE SESSIONID = @sessid
-- set the default seq_no
SELECT @seq_no = 1
-- get the max abrid. if no record return the seq_no will be 1
SELECT @seq_no = convert(integer, max(right(abrid, 4)))
FROM dbo.ABR_HDR
WHERE left(abrid, 7) = @ay + @ddo
-- convert @seq_no to string prefix by 0
SELECT @abrid = @ay + @ddo + right('0000' + rtrim(convert(char(4), @seq_no)), 4)
Insert into dbo.ABR_HDR (ABRID, HDR_MODE, HDR_DDO, HDR_AY, HDR_REQUESTOR, HDR_DT, HDR_SUBJECT, HDR_DESCRIPTION, HDR_STATUS)
SELECT
@abrid,
@mode,
DDO,
AY,
REQUESTOR,
DT,
SUBJECT,
DESCRIPTION,
@status
FROM dbo.Temp_ABR_HDR
SELECT @id = @@identity
return @id
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,
@sessid varchar(100)
AS
declare @ay char(4)
declare @ddo char(4)
declare @abrid varchar(50)
declare @seq_no int
SELECT @ddo = a.DDO_DSCR_SHORT
FROM dbo.DIM_DDO a
JOIN dbo.Temp_ABR_HDR b
ON a.DDO_ID = b.DDO
WHERE b.SESSIONID = @sessid
SELECT @ay = AY
FROM dbo.Temp_ABR_HDR
WHERE SESSIONID = @sessid
-- set the default seq_no
--SELECT @seq_no = 1
-- get the max abrid. if no record return the seq_no will be 1
--SELECT @seq_no = convert(integer, max(right(abrid, 4)))
--FROM dbo.ABR_HDR
--WHERE left(abrid, 7) = @ay + @ddo
-- convert @seq_no to string prefix by 0
--SELECT @abrid = @ay + @ddo + right('0000' + rtrim(convert(char(4),@seq_no)), 4)
SELECT @abrid = @ay + UPPER(@ddo)
Insert into dbo.ABR_HDR (ABRID, HDR_MODE, HDR_DDO, HDR_AY, HDR_REQUESTOR, HDR_DT, HDR_SUBJECT, HDR_DESCRIPTION, HDR_STATUS)
SELECT
@abrid,
@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.

Hello all,I´m currently using a SQL Serve 2K. Would like to do a selectwhich returns the row number - this should not be physically stored inthe database. So for example, I would like to do a query against theCUSTOMER table and receive:* rowID || name1 Evander2 Ron3 Scoth4 JaneI don´t want to store the ID, because if I change the order byclause, the sequence may modifiy, and, for another example, having thesame set of data, I would receive:* rowID || name1 Scoth2 Ron3 Jane4 Evander could someone help me ?best regards,Evandro

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.

Hi,
I have written the following StoredProcedure
Code:
create Procedure spCreateQuestion(
@QuestionName varchar(30)
)
as
declare @newAnswerId int
declare @newQuestionId int
set @QuestionName='New Question'
BEGIN TRANSACTION Q1
--Creates New QuestionId with AnswerId 0
INSERT INTO Questions(QuestionId,Name,AnswerId)
SELECT 1 + COALESCE(MAX(QuestionId), 0),RTRIM(@QuestionName),0
FROM Questions
--QuestionId just now created
SELECT @newQuestionId=QuestionId FROM Questions WHERE Name=@QuestionName
BEGIN TRANSACTION QA1
--Create an AnswerId
INSERT INTO Answers(AnswerId)
SELECT 1 + COALESCE(MAX(AnswerId), 0)
FROM Answers
--AnswerId just now created(I hope not the best way to do like this)
SELECT @newAnswerId=MAX(AnswerId) from Answers --is it the best way to call statement like this or any other way better than this
--update Questions Table with this new Answerid
UPDATE Questions
set
AnswerId=@newAnswerId
where QuestionId=@newQuestionId
COMMIT TRANSACTION QA1
COMMIT TRANSACTION Q1
I think the second Transaction is not locking the table.so some how i should be
able to get the newly create AnswerId
i can't use the identity column in my tables
Can some one please have a look at it and suggest me how do we go about it..
Does 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.

is there a set based function to accomplish this in SQL 2008?
I have a table like this
create table
#invoice (invoice_no varchar(5), invoice_amount int)
INSERT INTO #invoice
SELECT 'A', 100 UNION
SELECT 'A', 200 UNION
SELECT 'A', 300 UNION
SELECT 'B', 400 UNION
SELECT 'B', 500 UNION
SELECT 'B', 600 UNION
SELECT 'B', 700
Now I want a output like this
INVOICE_NO AMOUNT SEQUENCE_NO
A 100 1
A 200 2
A 300 3
B 400 1
B 500 2
B 600 3
B 700 4
The sequence_no should set back to 1 on change of invoice_no
these are items in a an invoice. they just want a sequence_no
I can do this using cursors, but if anyone can help with WHILE LOOP
would be great
THANKS

I am newbie to SQL Server 2005.
Can any experts please give me code for how to generate automatic sequence numbers in sql server 2005?

Hi,
I have an error table that is to be updated by more than one package.
There is a sequence number generated in the error table. It is generated by using the max value of the previous data present in the table.
When more than one package runs parallely, conflict occurs in generating the sequence number.
How can this be handled?
How 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?
Why log sequence number gets broken in SQL server?

Does any one have information about how 'large' the SQL Server Sequence Number generator can go,

I want to create a unique ID that identifies a row.
Id:STU+(SeqNumber) for Student and

[Question]:But how can i create sequence number and store it for use like that of ORACLE
Current Idea:Based on registration info if type is student generate STU+seq num and insert to table along with username and other details and if employee like wise.
So a procedure will receive this from user and append that with seqnumber and stores that in the table

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!
