Jun 29, 2006hi.i am using ms sql server 2000. can somebody tell me what the code would be to remove all the values in a given column and replace them with the associated number of the row with each execution. so, if i have a column:nums|1||2||3||4|and somebody deletes record |2|i would like the nums colum to update to|1||2||3|not:|1||3||4|it seems simple but i am having a hard time with this. how is it done?thanks.
View 14 Replies View RelatedDeterming The Identity Number After An INSERT INTO
Jan 5, 2006All of my tables in my database have keys that are autonumbered (datatype int with identity set to 1).
Whenever I go to insert a new entry into the table I execute an INSERT INTO command and leave off the key field, so that it is automatically inserted with the new row.
However, I need to that number, so that I may insert it as foreign key into another table. How would I go about retrieving this number? I thought about doing a Max() on that field, but I am not confident that SQL server would always use a higher number than everything previous. Is there a better way of accomplishing this? Is my design flawed from the start? Any feedback would helpful. Thank you.
Two Column Auto-number/identity
Oct 8, 2007Hi,
I have the following two tables:
Code:
create table RECORD
(
ID int not null,
Issue_descr varchar(256) not null,
Priority varchar(5) not null,
Status varchar(12) not null,
Date_add varchar(10) not null,
Date_due varchar(10) not null,
Date_complete varchar(10),
PName varchar(32),
primary key(ID),
foreign key(PName) references PROJECT(PName)
);
and
Code:
create table STEPS
(
ID int not null,
Num int not null,
Descr varchar(256),
Date_due varchar(10) not null,
Date_complete varchar(10),
Status varchar(12),
primary key(ID, Num),
foreign key(ID) references RECORD(ID)
);
I have set PK "ID" in table RECORD to auto identity(1,1). I have done the same for PK "num" in table STEPS.
However I am seeking this behavior in STEPS:
ID num
-- ----
19 1
19 2
19 3
20 1
20 2
21 1
but what I'm getting is PK num doesn't "reseed" or reset to 1 as "ID" changes. PK num just auto-increments regardless of ID. Is there a workaround?
Thanks.
Calculate/create Row Number Without Identity
Jul 23, 2005How do I output a row number for a table solely for the purpose ofquerying for a unique row?In my problem, the table from a legacy system does not have a primarykey, so it limits various querying I'd like to do that identifiesuniqueness in the table.The problem is that since I'm using DTS to simply copy the table toSQL, I don't want to create identity rows.

Jul 20, 2005I am migrating a web application I wrote from ASP to ASP.Net, and fromAccess to MS SQL server.In the Access version, I did not use the auto number for creatinginvoices and other documents, because I heard somewhere (perhapsincorrectly) that if the db was ever compacted or otherwise changed,it could change the values of the auto-numbers. Not a good thing.So I wrote a routine that, just before creating a new record, wouldlook for the highest value in the table and create the new record withthe next number.So my question is, am I safe in assuming that in MS SQL that I can seta starting number for the next, let's say, invoice and that newnumbers will be issued in sequence, and that these numbers will neverchange? What happens if an invoice is deleted? is the number goneforever? Just wondering how others deal with these issues...thanks.Larry- - - - - - - - - - - - - - - - - -"Forget it, Jake. It's Chinatown."

View 4 Replies View RelatedHow To Manage IDENTITY In Tables With Large Number Of Rows?
May 23, 2002Table structure: col1 IDENTITY (seed=1 increment=1) + few other columns (col2...col7) + one text column (col 8)
I have around 50,000,000 rows per day inserted in the table T1. At the end of the day 40,000,000 rows are deleted. I have to keep the records for 12 months and then archive it. Database is 24/7 web serving and there is no down time allowed. IDENTITY column will go out of range (overflow) after less than two years, unless the identity seed is reset to the start value (seed=1, increment=1).
At the end of 12th month data is archived in another table and only last month is kept in the table T1. So table T1 enters new year with data from last month of the previous year. There are few other tables that refer to this table by using there own field with values from T1.IDENTITY column (referential integrity is not enforced). Identity column in T1 is needed as a unique id for some search actions. Performance is an issue therefore bigint data type is used for this identity column rather than decimal.
Another problem I have is how to do table update on one column (1 mil rows to be updated out of 2 mil of rows) with the minimum impact on the users who are querying this table heavily. Not need to mention that it is web app 24/7 no down time.
Thank you in advance.

SPROC Probs Creating A Non-identity Number Column
Jun 26, 2006Hi. I am trying to figure out the code for sorting a manual (non-identity) number column in my table. the purpose is to
show the user's pictures in perfect order (1,2,3,4,5,6...).
The Jist of my problem... When a user first inserts six pictures, he gets:
|1|
|2|
|3|
|4|
|5|
|6|
All is good. But, say he deletes picture |3|. Now the list order looks like this:
|1|
|2|
<- |3| is removed
|4|
|5|
|6|
And, then he inserts two more pictures, now he his this:
|1|
|2|
|4|
|5|
|6|
|7| <- |7| & |8| are added
|8|
What i want to acheive is a "reshuffling" of the number order every time a picture is removed. So, when |3| is removed, |4| becomes |3|, |5| becomes |4| and so on. There should never be a gap in the order.
I am new to stored procedures, and have been trying to figure this out. Below is my guesswork:
Code:
ALTER PROCEDURE dbo.sp_NewPersonalPic
(
@photo_name VARCHAR(50) = NULL,
@photo_location VARCHAR(100) = NULL,
@photo_size VARCHAR(50) = NULL,
@user_name VARCHAR(50) = NULL,
@photo_caption VARCHAR(150) = NULL,
@photo_default BIT = NULL,
@photo_private BIT = NULL,
@photo_number INTEGER = NULL,
@photo_date DATETIME = NULL
)
AS
BEGIN
SELECT @photo_date = CONVERT(DATETIME,convert(char(26), getdate(), 109))
END
BEGIN
SET @photo_number = 1
SELECT
@photo_number = (
SELECT COUNT(*)
FROM dbo.PersonalPhotos b
WHERE
a.photo_date < b.photo_date
)
FROM
dbo.PersonalPhotos a
ORDER BY
a.photo_date
END
BEGIN
My thinking is that it would be a safe bet to use the "photo_date" column as a litmus for my "photo_number" column (ie, the most recent record inserted by the user will always be at a later date than the previously inserted record). So:
photo_number photo_date
|1| 2006-06-26 21:43:36.653
|2| 2006-06-26 21:43:50.000
|3| 2006-06-26 21:45:25.217
|4| 2006-06-26 21:45:33.763
|5| 2006-06-26 22:39:42.670
|6| 2006-06-26 22:39:49.200
If |3| is removed above, the numbers are reordered based on the time of entry sequence.
Any suggestions on how to acheive this in my stored procedure? Currenly, i get the correct order, but it goes crazy when i delete and add.
Thanks and sorry for the verbose post.

Last GASP On Insert Row In Table With Identity Field, And Get New Identity Back ?
Jul 9, 2006While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,

How To Use Identity On Non-identity Column (with Concurrence)
Aug 1, 2014I'm working with a third-party database (SQL Server 2005) and the problem here is the following:
- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).
- The PK of T is an Integer.
Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.
Considering that I can't change the PK, what is the best approach to solve this problem?
To sum up:
* I need to have processes in parallel inserting on T
* I can't change anything on T
* The PK is NOT an Identity

Limitations In Term Of Number Of Tasks And Number Of Columns
Jun 5, 2007Hi,
I am currently designing a SSIS package to integrate data into a data warehouse fact table. This fact table has about 70 columns among which 17 are foreign keys for dimension tables.
To insert data in that table, I have to make several transformations and lookups. Given the fact that the lookups I have to make are a little complicated, I have about 70 tasks in my Data Flow.
I know it's a lot, but I can't find a way to make it simpler. It seems I really need all these tasks.
Now, the problem is that every new action I try to make on the package takes a lot of time. At design time, everything is very slow. My processor is eavily loaded each time I change a single setting in one of the tasks, and executing the package in debug mode takes for ages. If I take a look at the size of my package file on disk, it's more than 3MB.
Hence my question : Are there any limitations in terms of number of columns or number of tasks that can be processed within a Data Flow ?
If not, then do you have any idea why it's so slow ?
Thanks in advance for any answer.
