How To Solve The Hole Of Identity Column?
Aug 8, 2004
Hi All
I use identity column in a Database.
when I delete some data, it cause the "hole" of identity column.
for example
1 John
2 Mary
3 Sam
4 William
when I delete Mary, the data in table are
1 John
3 Sam
4 William
so the hole of identity column is "2"
I don't want there is any hole of identity column..
I hope the result is
1 John
2 Sam
3 William
IS there any solution for this problem?

Hello All:
I am not sure if I wrote the question's title appropriatly or not.....but anyways I wud try to explain the problem.
I am facing a problem solving the following task in MS Access (I believe it can surely be solved in access or SQL server).I am posting a sample table format here for reference and also postin the expected result table there-after.
The problem goes like this.(Read Carefully)
I have a table which contains a payment history with one row per account (each account number is unique) and related payment history for each account.
Sample Table:
AcctNo Dt1 P1 Dt2 P2 Dt3 P3 Dt4 P4 .........
------------------------------------------------------------------------------------------------------------
101 | 11/07/2002 | 10.00 | 11/07/2002 | 20.00 | 01/17/2003 | 120.00 | 01/25/2003 | 20.00
201 | 10/28/2003 | 30.00 | 10/28/2003 | 25.00 | 03/22/2004 | 130.00 | 03/22/2004 | 75.00
301 | 04/07/2005 | 40.00 | 04/23/2005 | 25.00 | 01/07/2001 | 140.00 | 01/07/2001 | 65.00
401 | 01/13/1999 | 50.00 | 01/13/1999 | 35.00 | 10/29/2002 | 150.00 | 10/17/2002 | 55.00
501 | 05/23/2001 | 60.00 | 05/02/2001 | 45.00 | 02/13/2000 | 160.00 | 02/13/2000 | 25.00
601 | 09/17/1998 | 70.00 | 09/15/1998 | 55.00 | 07/07/1998 | 170.00 | 07/07/1998 | 15.00
701 | 12/11/2000 | 80.00 | 12/29/2000 | 65.00 | 11/27/1999 | 180.00 | 11/28/1999 | 15.00
where Dt is date and P1/2/3/... is payment.There cud be 1 or more than 1 payments in a particular month as shown.
The original file has more than 200 columns for the payment i.e till Dt200,P200
I need to see aggregated monthly payment history for all accounts. i.e. a table for all accounts with related payments for each month (its OK if a day vary in particular month...consolidation shud be monthly) starting from the earliest to the latest possible.
Result:-
Acct Month Pay Month Pay ...........
----------------------------------------------------
101 | 11/2002 | 30.00 | 01/2003 | 140.00 ...........
201 | 10/2003 | 55.00 | 03/2004 | 205.00 ...........
301 | 04/2005 | 65.00 | 01/2001 | 205.00 ...........
401 | 01/1999 | 85.00 | 10/2002 | 205.00 ...........
501 | 05/2001 |105.00 | 02/2000 | 185.00 ...........
601 | 09/1998 |125.00 | 07/1998 | 185.00 ...........
701 | 12/2000 |145.00 | 11/1999 | 195.00 ...........
I hope I have tried to explain the problem in as much detail as possible.

I have table of three column first column is an ID column. However at creation of the table i have not set this column to auto increment. Then i have copied 50 rows in another table to this table then set the ID column values to zero.
Now I have changed the ID column to auto increment seed=1 increment=1 but the problem is i couldn't figure out how to update this ID column with zero value set to each row with this auto increment values so the ID column would have values from 1-50. Is there a away to do this?

I'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

Hi all,
The requirement is to have a table say 'child_table', with an Identity column to refer another column from a table say 'Parent_table'..
i cannot implement this constraint, it throws the error when i execute the below Alter query,
ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id)
REFERENCES parent_table (parent_id) ON DELETE CASCADE
the error thrown is :
Failed to execute alter table query: 'ALTER TABLE child_table ADD CONSTRAINT
fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE
CASCADE '. Message: java.sql.SQLException: Cascading foreign key 'fk_1_ct' cannot be
created where the referencing column 'child_table.child_id' is an identity column.
any workarounds for this ?

I have a purchased product that has a DB with several thousand tables in dbo. I can't change anything with the default dbo schema other than security. I have a table called dbo.ACCOUNT. It has information from multiple sites on it. I have a reporting team that need only access the information for SITE 1 on the ACCOUNT table and anything in the other 1000+ tables in the dbo schema.
I created a role (Analytics) and granted select access to dbo. I created a schema (Analytics) and assigned it the role. I created a view in the new schema called Analytics.ACCOUNT with a WHERE SITE = 1 clause on it. If they use the view, they see only the things they should. My problem is they can still do a select * from dbo.ACCOUNT and see everything they shouldn't see. How can I close that hole? I am not seeing a solution. If there is no way to fix this with roles/schemas/views, what else can I do?
Some of my pain points. I have this issue with about 30 tables. Creating custom table(s) to isolate data for each site will cost me another 2T of storage. Loading those custom tables every day would be cumbersome. Keeping the DDL in sync with the source table would be cumbersome. With the way I have it set up now, if I deny access to the source tables the view breaks because it needs access to the source tables to dynamically build the view. Here is the code I ran to create everything.
USE[DB]
--create test user login
CREATE LOGIN [Analytics_ETL] WITH PASSWORD=N'XXXXXXXXXXX'
GO
--create user in test database
CREATE USER [Analytics_ETL] FOR LOGIN [Analytics_ETL] WITH DEFAULT_SCHEMA=[Analytics]
[code]....

Hi guys,
If I have a temporary table called #CTE
With the columns
[Account]
[Name]
[RowID Table Level]
[RowID Data Level]
and I need to change the column type for the columns:
[RowID Table Level]
[RowID Data Level]
to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time.
What will be the right syntax using SQL SERVER 2000?
I am trying to solve the question in the link below:
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance,

ALTER COLUMN
[RowID Table Level] INT IDENTITY(1,1),
[RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE
MODIFY
[RowID Table Level] INT IDENTITY(1,1),
[RowID Data Level] INT;

Having an identity column in target table, how do I use SQL 7 DTS ?
In Import wizard, I chose 'ignore' in source, checked Enable Indenity Insert - DTS failed with a msg like - a column cannot have NULL...
In DTS package, had Fast load and Enable Indenity checked - no luck !
Unchecked Enable identity, do luck.
What would be the standard procs for this since this sounds like a very common
senario.
What I am expecting is to insert from source and SQL would take care identity column automatically.
Appreciate your help very much !

I have a table that has a field that will not accept null values. I was trying to create a new table with a new field that would accept null values. I would then drop the original table and rename the new table. The problem is my key field has the Identity column (Autonumber) turned on. This allows the recordID to be automatically generated. Is there anyway to bypass the Identity Column feature and still keep it there future records? I already tried the "with Nocheck Clause" but does not work.

Kudos to y'all! On most of my tables, I'm using a column of data type numeric and properties set as Identity with no replication. Now I know that it can handle only a length of 9 and obviously not nullable. Now by length of 9, does it mean in bytes or literal digits. If it is, then that would mean that it would reach only up to 999,999,999. What happens then if it reaches that digit?

Hi Everyone:
I am new to Mobile programming. I am now working on a mobile project. I encounter an issue when I sync the data:
cause I can't modify the schema, so I have to use RDA instead of Merge replication on sql server 2005.
However, There is an identiy column on each table I will pull them down to local mobile database. And I will use those identity columns to connect tables. Even worse, the photo's new name will combine the photoID which is an identity column. There would an issue, if i sync data, the photoID would be same on different local mobile databases. And there would be generate same identity value when users sync data.
How can I avoid those issues? If you have any good ideas, please help me out so that I can meet the project deadline.
Thanks
James
