T-SQL (SS2K8) :: Programmatically Generate A Number Sequence?
Sep 3, 2014
I'm trying to do a simple insert into a table, something like this:
insert into sometable (ID, somecolumn)
select 'Task-ID', somevalue from SomeOtherTable
where something = 'someothervalue'
(or something to that effect)
So, the SELECT would generate something that looks like this:
What I don't know is, how do I programatically generate the number sequence? Note: I do not have admin rights to the table, i.e. I cannot just change a column to IDENTITY.
Also the 'Task-ID' must remain part of the ID; in other words, I can't just generate a GUID, and it needs to be easily identifiable.
What I'm hoping to do is rewrite my SQL like this:
insert into sometable (ID, somecolumn)
select 'Task-ID.' + (generated seq #), somevalue from SomeOtherTable
where something = 'someothervalue'
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..
Hi all anbody can help me writing sql code for this. All i need is to generate sequence basing on id_no Ex: if ID=ABC(twice) in seq_col as abc --1 abc ---2 Tables which I have Uniques_No ID_NO SEQ --------------------------------------------- 1 ABC 2 ABC 3 ABC 4 BBC 5 BBC
Expected results as below : ------------------
Uniques_No ID_NO SEQ --------------------------------------------- 1 ABC 1 2 ABC 2 3 ABC 3 4 BBC 1 5 BBC 2

I have a report that I'd like to involve in delivering tons of PDFs for each of our customers for a billing cycle. There is a table that the report reads from that gives it all its data necessary for the report (which is a customer bill) and the table also has a column that has the file name for the PDF for that particular customers bill for the report. Basically each table row represents one output report (bill) and each table row has its name nicely formated for me. Writing the report is not a problem. Figuring out how to run through thousands of rows generating a PDF for each with the file name from the table is my challenge.
I would like to create either a SP or a SSIS package (that is scheduled) that can run a report for each line of data in my table and spit out a PDF file to a UNC path. It might have to generate thousands of PDFs to a UNC path that has plenty of space. There will be another SSIS package that moves the PDFs later to their proper directory.
So, is there someone who has done this before? Any suggestions? Is there a quick path to doing this, would it take a ton of time? Any tutorials out there?
Thanks, Keith
p.s. My preference is to do this in SP's or SSIS and if I need a .NET language to do that in VB.NET, but I'd rather avoid that if I can.

Hi, I've a question, if I've the LSN (Log Sequence Number) of a transaction, keep with the program "Log Explorer", can I know which is the IP of the user that have do the transaction (perhaps serching in a log file of the Win 2000 Server) ? 10x, Clara

is it possible to generate a number sequence in a query (without using loop). I want the output to look as ------- ID ------- 1 2 3 4 5 6 7 8 9 .... upto the last number I give in the query
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
We have an application which has had a big design floor and is now causing an issue which needs to be rectified. It inserted data in batches of 2000 rows which should have always been in sequence. A column was used which recorded an ever increasing numerical value for each row that was inserted. So batch 1 would have a start value of 1 and an end value of 2001. Batch 2 would have a start value of 2002 and an end value of 4002 etc.
The problem is the application which inserted these records in order, missed some records. So in actual fact we have:
Now the missing data has been found, it will be inserted at the end of the table, as we cannot insert it where its should be as the sequence value has been used by the next batch already. Lets say the table is 10,000 rows so far, so the seq for batch 2, for example, will be 2002-3998, then after the missing data is inserted, 10,001 - 10,005. The application uses these sequences to show the range of data so where it should be 2000 rows being returned, it would now show 8003 rows - all the other batches between the first and last sequences for the batch!
I need to change the sequence values across the whole table so they are in order. I can select the data in the correct sort order as there is another unique key on the table, but unsure how best to use this to change the sequence column to be in order for all rows. Adding an identity column would work and then remove and rename the seq column, but I obviously cannot add this based on another columns sort order. The identity column would use the clustered key which is in the incorrect order!!
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.
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.
Hi, I got stuck with a trivial issue. I have a table named T1 having column as Col1 (INT). I have another table named T2 having columns Col1(Int), COl2(Int). Following are the reacords in my table T1.
Col1 ---- 1 1 1 1 2 2 3 3 3 3 3 4 5 6 6 7
And I want to migrate the data from T1 to T2 where the Col1 data of T1 will get migrated to Col1 of T1 and after the migration is done the T2 should have the data like this.........
Hello folks, I have a table where the records are like followings.
ID Value --------------- 1 aa 1 aa 1 aa 1 bb 1 bb 1 bb 1 bb 1 cc 2 pp 2 dd 2 dd 3 qq 4 aa
I need to include one column "SeqId" which will be having value based on the 1st 2 columns (ID + Value). I am struglling with this since last few days. Can I request you guys to help me out in this reagard.
ID Value SeqId ----------------------------- 1 aa 1 1 aa 2 1 aa 3 1 bb 1 1 bb 2 1 bb 3 1 bb 4 1 cc 1 2 pp 1 2 dd 1 2 dd 2 3 qq 1 4 aa 1
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
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?
Hallo,Hot to get unique, sequential number during executionof stored procedure ?I can create table with autoincrement column,add record, get ident_current and delete recordeach time i need the number.However its not elegant i guess.best regardspluton
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++)
SELECT row_number() over (ORDER by a.employeeID) as rec_num, a.* FROM EmployeeA a UNION SELECT row_number() over (ORDER by a.employeeID) as rec_num, a.* FROM EmployeeB a
1 777 Mike HR 2 888 Susy HR 1 111 Smith TECH 2 222 John TECH 3 333 Lenny TECH
How do i get sequence number for all of this records. The rec_num reset for every statement. I want the records numbering for second statement continue from first statement so that it can be like this :
Hi all,Ive been trying to figure this out and has proven to be quite difficult for me. Lets say i do a select on all client numbers from a clients table i would want the first available number returned.Given the client table below my query would return 4 because its the lowest number availeble. Thanks. client tableclnum12367
Database in:SqlServer builtin interface with VS05 Using:ASP.NET VISUAL STUDIO 2005 I want to create a unique ID that identifies a row. Id:STU+(SeqNumber) for Student and Id:EMP+(SeqNumber) for Employee [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
