I have a demo database in SqlCE that I am getting ready to deploy. I deleted a bunch of test records and now want to reset the identity columns. The compact method runs fine, but the identity columns are not being reset? So when I add a new record, the returned identity value is over 1,000 even though the highest value is only 50.
Any help is greatly appreciated!
Kind Regards,
Mat
I have a table where I delete all the records, then reload. can I reset the identity to (1,1) Is there a SQL command for that?

In my application , DB has a large table. I write a small program to clear the table whenever the size of table is over 50 MB. At that time , I want to reset identity as 1. How can I do that?
Currently , my program delete old table and generate a new one with the same schema when the table is too large.But this is kind of ugly.
Can a column of Identity type reset after it reaches its maximum value?
Thanks,

How can I reset an identity Int column back to start with 1 if I remove all rows from the table?

Hello,
Can I reset the IDENTITY seed of a Table column without delete/drop the table?
I want to delete all the table rows, restore de seed, and restore a
backup made on a XML (using SET IDENTITY_INSERT Table ON)
I cant drop the table due to acount restricctions.
regards,
Edu
Obviously to delete all records from DB table is simple, however, I would like to make my whole Live DB pretty much empty. I've copied all my data from my test DB over to my live DB (didn't mean to but I did). I would like to remove all the data and the identity values, resetting them back at their original values. Is there a simple way or do I have to do it the hard way. That being going in and removing Identity, saving and then placing identity back on the DB Table.

i have a table with the following fiels ,
Column NameDataType
Sno intIdentity = Yes , Identity Speed =1 , Identity Increament =1
namechar
Now i entered data and coneected to database, worked.Now after cheking all the data entered with the form , now i have to send the table to client place.
The problem is , the sno column has the value which i entered last. now if i delete all records , then also the record no doesnot become 0.
what i have to do, to set the sno column to 1 again.
Reset the Identity IncrementHello:I have a table with a bigint type column (field) that has an identity seedof 1 and an identity increment of 1. The column is the primary key for thetable.After I backup and clean out the database (delete all of the data in the DB)I need to have the column with the identiy seed/increment value reset to 1automatically. (start counting at 1 again). How does one do that, becauseas it is now, the DB keeps increasing the value of the column from where itleft off, regardless of the fact that I deleted all of the data in thetable.The DB is MS SQL Server 2000.Thanks and appreciate any help.Ryan Kennedy

I have a table with Identity column starting from value 1 and autoincrementing 1 for every new value. I inserted (5) rows and then deleted these rows. But, when i insert a new row, it was taking the last identity value(5)and inserting the rows with next identity value i.e., 6 for this column. I dont want that. Everytime, I delete and insert rows in to this table.I wanted the rows to start with 1 for this column.
Any help on this is highly appreciated.
Thanks!
Hello friends,
I have a table in SQL server 2005. it contains one identity column named EmpID
it's datatype is int isidentity and auto increment by 1.
I deleted all the records from this table.
Now I want that EmpID should start again from 1 how can I do it ?
Thanks & Rgds,

Changing the seed and increment values on the identity column
- CREATE TABLE MyCustomers (CustID INTEGER IDENTITY (100,1) PRIMARY KEY, CompanyName NvarChar (50))
- INSERT INTO MyCustomers (CompanyName) VALUES ('A. Datum Corporation')
- ALTER TABLE MyCustomers ALTER COLUMN CustId IDENTITY (200, 2)
When i excute the Alter command, following error comes:"Incorrect syntax near the keyword 'IDENTITY'."I've picked the example from SQL SERVER 2005 books online.Please let me know if we can change the seed value on the identity column from a sql command.
I have a test database that is being moved to the production server. Currently in one of the tables I have an identity seed for each record. Is there a way to reset it back to zero. I have deleted all my records but it still doesnt work, and I dont want to create a new table.
Thanks
Is there a way to delete all items from a table that has an identity column and to reset the counter for all new insertions so that they begin at '1' again?
View 5 Replies View RelatedI have a remote DB I am wokring with at present. The DBA has provided me with a non owner LOGIN so I can't copy tables from the live to the staged DB as objects I can only copy tables and data.
The PKEY and IDENTITY COLUMNS get reset to just regular columns on each table. I can restore the PKEY constraint and have come across the DBCC CHECKIDENT to get the new ident value. I just can't figure out how to set a column to be an identity. The ALTER TABLE command isn't having any of it.
I am obviously missing the right bit on Books online
any suggestions?
many thanks

I know that TRUNCATE TABLE can be used to reset the identity counter, but it can't be used on a table referenced by a foreign key. Anybody knows how to do that? Thanks.

View 1 Replies View RelatedIs there a way to reseed the Identity column in SQL Server Compact Edition? The following command does not appear to work DBCC CHECKIDENT (Table_Name, RESEED, 0) and I cannot seem to TRUNCATE the table either. Not sure if table truncation is even supported.
Hi,
we are using a custom persistence framework on an SQL Server Compact Edition (3.5) database. It might occur, that a class gets persisted into a table having only a single IDENTITY column. Even worse, there may be additional columns in the database the persistence layer is not aware of.
I'm now looking for a way to insert rows into that kind of table without specifying any column values. In SQL-Server 2005 (also Express edition), there is a form
INSERT INTO table DEFAULT VALUES;
which does the job. Unfortunately, this construct doesn't seem to be supported by the Compact Edition.
Any suggestions? Many thanks in advance!

Hi all!
I have been doing some testing with transactional replication. I have a table (TEST) with the following columns:
[id] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,
[name] [varchar](50) COLLATE SQL_Latin1_General_CP850_CI_AS NULL,
[stock] [int] NOT NULL CONSTRAINT [DF_Prueba1_stock] DEFAULT ((0)),
I want the table rows to have an independent stock value for each database. So,
I made a transactional publication with updatable subscriptions, to replicate all the table columns, except the stock column.
The problem is when I reset subscriptions: the table is deleted an created again on the subscriber, so all the data stored at the stock column is lost. I tried to solve this changing the "Action if name is in use" option at the publication. I choose to keep the current object without changes, but I began having problems with the generation of the identity values at the subscriber.
Any suggestions will be welcomed
Thanks in advance ;-)
I keep getting a waring:
[Production IDW [1]] Warning: Truncation may occur due to retrieving data from database column "Industry" with a length of 16 to data flow column "Industry" with a length of 8.
When I look at the industry lookup table the column size is 50. But the data flow metatdata is saying the oclumn is 8. How can I change the data flow column? When I try to edit it and click on metadata it is uneditable. The field it is matching to is 50 and the field it is coming from is 16.
Hi,
I am planning to use transacational replication (instead of merge replication) on my SQL server 2000. My application is already live and is being used by real users.
How can I ensure that replicated data on different server would have exact same values of identity columns and date columns (where every I set default date to getdate())?
It is very important for me to have a mirror image of data (without using clustering servers).
Any help would be appreciated.
Thanks,

Hi,
I have a table with the following example data
idcol1col2col3
----------------------------
1abcnullnull
1abcnullnull
1null123null
4alphanullnull
4alphanullgamma
1abc987null
I would want to reduce that somehow to
idcol1col2col3
-----------------------------
1abc123null
1abc987null
4alphabetagamma
First thing in my mind was distinct over multiple columns, but I haven't found any resource mentioning that possibility.
I don't immediatly see a way without (complex) looping.
Can anybody put me on the right track?
btw, I know that Id is not an id.
It's a table var that holds an id of a table combined with fields of other tables.
I have an application with highly compressable strings (gzip encodingusually does somewhere between 20-50X reduction.) My base 350MBdatabase is mostly made up of these slowly (or even static) strings. Iwould like to compress these so that my disk I/O and memory footprintis greatly reduced.Some databases have the ability to provide a compressedtable, compressed column, or provide a user defined function tocompress an indvidual Field with a user defined function[ala. COMPRESS() and DECOMPRESS() ].I could right a UDF with an extended prodcedure if I need to but I'mwondering if there are any other known methods to do this in MS SQLServer 2000 today?--Frederick Staatsfrederick dot w dot staats at intel dot com (I hate junk mail :-)
View 6 Replies View RelatedI am trying to use the ListChildren method to query the SSRS Catalog. I am using this as a dataset in a report. I'd like to see more columns, in particular the Description column, included in the dataset. Is there some way to tell ListChildren what columns should be included or is there some other method to obtain this information.
ListChildren returns ID, Name, Path, Type, CreationDate, ModifiedDate, CreatedBy, ModifiedBy, xmlns.
I'd prefer not to query the Catalog table directly.

Just to confirm, do identity columns and XML columns work OK with database mirroring ? That is, all data types are supported with mirroring, and identities aren't an issue ?
Transactional replication with identity columns was a right pain in the **** in SQL 2000. I'm assuming that mirroring doesn't have these issues, but want to be sure.
Can anyone describe how SQLServer calculates identity
columns? Does it use some internal counter when generating the next identity,
or something a little more mundane such as gets the highest existing identity
value at the point of the insertion and increments it by the IDENT_INCR value
of the identity column?I’m not worrying about reliability or gaps in values, but i
am wondering if it would be less efficient for me to manually manage the
identity/primary key in the form of a counter in another table used to generate
the new identity, or simply let the DB do it for me. I dont mind if there are
gaps in the sequence etc. so would it be less efficient for me to calculate the
field than SQLServer itself? Basically, is the overhead to the DB of me doing
it greater than the overhead of the app doing it...Thanks
First off I am NOT a DBA.
I have a question about IDENTITY columns. I am working for a client that has an entire employee database that uses IDENTITY columns without any Primary keys defined. I have never seen this done. Is it ok or should I recommend that it be changed to use Primary keys?
The DBA that built the database is no longer with the company and the client has no DBA. Where can I get some information on how to use IDENTITY columns? I did not get much from the help file.
TIA
Nate
Where do I find the seed and increment values of the identity column in database.
If possile can u suggest query for that Pl.
Thanx in advance

I have been using the following query to identify the IDENTITY columnsin a given table. (The query is inside an application.)select column_namefrom information_schema.columnswhere table_schema = 'user_a' andtable_name = 'tab_a' andcolumnproperty(object_id(table_name), column_name, 'IsIdentity') = 1This works. When "user_a" performs the query, everything is OK.Now, another user wanted to use the same application. So, "user_b"clicks on a button, and the exact same query as above is run. (Nosubstitutions are made; user_b is trying to see the identity column in[user_a].[tab_a]). However, the query returns null, instead of theidentity column name. User_b can read the table and select from itjust fine.Why am I getting two different results against the same query? Do Ineed to rewrite the query to go against different information schemaviews?
