Anyone has the standard approach for handling the identity column with replication environment.
Currently i am using following process.
http://www.databasejournal.com/features/mssql/article.php/3483421
I want to know if someone have some generic script to do this or much easier way..
Table 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.

In my simple table in MSDE 2000A, I have an image field. I have enabled 'text in row' using the stored procedure 'sp_tableoption'.
How do I get jpeg images in the table, and how do I read them?
I am using merge replication with automatic identity range management
I want to be able to give a disconnected subscriber a warning message if a certain percentage of the allocated subscriber identity range has been used
- so that they can make sure they reconnect soon to obtain a new identity range
I can get the current identity value OK, but I can't find a good way of finding the current permitted primary and secondary ranges
The information is available in the check constraint, but I don't really want to have to parse this!
CONSTRAINT [repl_identity_range_0DF907AC_40CF_4849_9BD0_2173C90A3805] CHECK NOT FOR REPLICATION (([ContactID]>(10000040000.)
AND [ContactID]<=(10000050000.) OR [ContactID]>(10000050000.) AND [ContactID]<=(10000060000.)))
I can't find any system view which will provide this information
Is there a recommended way of doing this?
Thanks

While 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,

I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?
I have a table with an integer field (contains test values like 2, 7,8,9,12,..) that I want to convert to an Identity field. How can this be done in t-sql?
TIA,

I have a table named PERSON and a field named PERSON_ID. How can I set this field to Autonumber? I know I have to use the IDENTITY command, but when I view this field in "design" view, all the IDENTITY options are grayed out.
How can I set this field with the IDENTITY properties?
Thanks
hi friends,i have an identity column in my table.(e.x : id )and it's identity increment is 1.when i insert a row the id field is 1, and in next record the field is 2.....now , i delete second record(id=2)and now when i insert a record again , the id column is 3.i want to record be 2 instead 3.plz help me.thanks

I created a small SQL Express database/ASP.net/C# application and in the learning process. Before I implement it I would like to re-set autonumber / identity field back to 1. Also, I need to start with the blank database. I am not sure how to approach that?
Can you assist?
Thanks
Hello friends,
I had created a web application and uploaded the application. Now the problem is with the DB. I had created the DB on the server (using script). But the fields that have identity field yes is not been set Now how I can set the fields identity field to yes. Fields are already there. Only I want to set there identity field to yes.Let me know how this can be done.
Thanks & RegardsGirish Nehte
Please, How can I get the value of the identity field of the register that I was including in the data base. I am using a stored procedure in SQLSERVER in a asp .net application and I need to show that for the user, it´s like the number of the reclamation.
View 2 Replies View RelatedIf my table has an IDENTITY field, say, the table schema is:
CREATE TABLE BBB(
id int NOT NULL IDENTITY(1,1),
name varchar(20),
job varchar(40))
My data file, which does not carry the IDENTITY field
and its field terminator. The data file looks like this:
debbie cao,programmer
John Doe,engineer
Mary Smith,consultant
I tried to use a format file to bulk copy data from the
data file to the table. Never had any luck.
On the other hand, if I put a comma before the name field,
say, the data file looks like the following:
,debbie cao,programmer
,John Doe,engineer
,Mary Smith,consultant
then, bcp works fine.
But, my data file is automatically generated. It does not
suppose to have the leading comma. Without the leading comma,
I have no idea how may I make bcp work. The SQLBOL says it
can be done. Does anybody have an example to show me?
Please help, thanks!
Dear Fellow Administrators,
We are experiencing an identity problem on a table with 3.7 millions rows of data in the table. The identity field is not auto numbering any more and are wondering if anyone has a suggestion on how to get the auto number field working again without doing a bcp and restoring the table back to the database from bcp. Any suggestions?
Thanks in Advance,

Greetings !
Having an unusual problem - have created several (20) tables in a database.
All of these tables have an identity field in them (defined as FIELDNAME int IDENTITY(1,1) NOT NULL ). In most of the tables this works as expected, but in 2, so far, when I do the first load (an insert based on a different database) the identity fields are all zero.
Have recreated the tables, changed the field name and location, etc.
Anyone have any clues ?
TIA

I need to update an identity field that I have on a table. How can

Folks
I am inserting some values into a table with the following stmt
Insert into table(number,name) values ('12','name')
In the table I have one more identity column ID. I know that I cannot insert a value in that column and the value is automatically increased once I insert a record. After this insert statment, I need to get the value
of the ID (the most recent one) in the next select statement.
ie Select @@identity from table (any condition????)
How do I get the most recent ID value? Actually I m inserting the records in a loop and the ID is increased for every insert.
Thanks for the help,
Hello...
New to SQL and have the following situation....
Example of table (currently)
PayID (Primary Key) PaymentNumber (Identity Field)
John 1
Tim 2
Chris 3
John (same as John above) 4
Jack 5
Steve 6
Would like to see it work this way
PayID (Primary Key) PaymentNumber (Identity Field)
John 1
John (same as John above) 2
Tim 1
Chris 1
Jack 1
Steve 1
Can the identity column be setup to start the counter over depending on value of PayeeID...If another Jack was added then the Payment Number would be 2 for Jack since there is already a record with value 1....
Hope this makes sense...
Thanks
I inherited a system with a SQL 2000 DB. We discovered an identity field named barcode with some values that are incorrect. About 1000 of the records contain a barcode field with 13 digits, not forteen as required. This field is a standalone field only used on an ID card. I would like to select those 1000 records and update the barcode field to 14 digits. Is there an easy way to do this? Thx

1. Can someone tell me how to replicate the identity field.
2. When I use the 'NOT FOR REPLICATION' option, I keeps getting synx error. Here is the command:
alter table tusers alter column {userid INT} IDENTITY (1, 1) [NOT FOR REPLICATION]. Do you know why?
3. When I use the transaction replication wizard, why some of the table do not allow me to replicate(There is a key and cross symbol on the articles selection)?
Thanks
I have a table which has a single column ,which is an IDENTITY colum.How do you insert values in it by using an insert statement.Thanks in advance

ok, so i get this error,
Exception Details: System.Data.SqlClient.SqlException: Cannot insert explicit value for identity column in table 'TBL_LAPTOP_BOOKINGS' when IDENTITY_INSERT is set to OFF.
i ran SET INDENTITY_INSERT TBL_LAPTOP_BOOKINGS ON before i ran my script... and i also checked, we are running SQL 2000 with service pack four, because of the cursor error....
so im just wondering, is there anyway to make identity_insert to always be on, or any other way to have a unique id in my booking_id field??
Thanks Guys, Justin
I want to kown if a field is an identity (counter) using a query or a stored procedure ?
Thanks
Hello,
I have a field in my table called "MyNewCounter",
where the data type is int.
Unfortunately I set the identity field to "No" instead
of "Yes" on this field.
Since this time a few thousand records were imported
in and this field is now set to a value of null for all records.
When I tried to change the identity to "Yes" and save
the table, I get an error indicating that the field can not
contain a null value.
If I populated this field with numeric values, would this
correct my issue? and if so, what SQL command would
I use to set the field value starting at 1 to increment
for each existing record?
I want to use the Identity field (increment 1,1) as a primary key andhave a unique constraint on my other field which is of type char.I am worried that related data in other tables may lose referntialintegrity if records in the ID table get messed up and need to bere-entered.Can you please advice on best way to do this. I definitely need anumeric id field because it makes the joins and queries so muchfaster.
View 9 Replies View RelatedI have an identity field on a table in SQL Server. The identity seedis 1 and the identity increment is 1. If I remove a record from thistable, the identity sequence is broken.

Server: Msg 4869, Level 16, State 1, Line 1
Bulk Insert failed. Unexpected NULL value in data file row 2, column 2. Destination column (taxon_author_id) is defined NOT NULL.
Since I have defined column 2 as an identity column, I don't understand why SQL Query analyzer is upset when I do not have a value in that field. To me, I would think it would auto-insert an integer (starting at seed 1 and incrementing by 1), but it doesn't. Could someone tell me what I'm doing wrong?
Hello,
Is it possible to generate a identityfield dynamically upon select, like this:
SELECT tempID AS identity(1,1), username FROM table1 ORDER BY username ASC
I want the output to be:
1 - Name12 - Name23 - Name3
The reason for this, is that i want to change the sort order in many diffrent ways, but i need to get the IDs from 1-?? even when the sort order changes.
Like:
SELECT tempID AS identity(1,1), username FROM table1 ORDER BY username DESC
I want the output to be:
1 - Name32 - Name23 - Name1
Patrick
To All,
I have a table [multiple entries over the web] where the identity field values do not appear in order using a simple SELECT [no ORDER BY]. Why?
Can anyone tell me of a way to reset the value of an Identity field back to its seed value after all the rows in a given table have been deleted and I try to re-populate it? There are foreign key relationships so I cannot just drop and recreate the table, and I really need to address this issue from within sql, rather than from the application.
Thanks, any and all guidance would be great :)
Hi!
I have a question that might sound obvious to some of you but (obviously) not to me.
I have a stored procedure that adds a new record to a table that has an [Identity] field (TableID).
I want to return the value of the TableID of the newly created record. Sound simple ?
Thanks.
