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.
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?

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.

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.

Column NameDataType
Sno intIdentity = Yes , Identity Speed =1 , Identity Increament =1

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!

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 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,

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 4 Replies View RelatedWhile 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 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?
Ok,I just need to know how to get the last record inserted by the highestIDENTITY number. Even if the computer was rebooted and it was twoweeks ago. (Does not have to do with the session).Any help is appreciated.Thanks,Trint
View 2 Replies View RelatedI have a table in my db that has an identity column as the primary key. I have deleted all the data and have tried to use truncate table on it to reset the identity column. The table has a number of foreign key constraints so it will not truncate.
Is there any way to reset the indentity column without removing the constraints?
My UDF
FUNCTION [dbo].[fn_concat_boxes](@item varchar(10), @week int, @type char(1))
RETURNS VARCHAR(100)
AS
BEGIN
DECLARE @Output varchar(100)
SELECT @Output = COALESCE(@Output + '/', '') +
CAST(quantity AS varchar(5))
FROM flexing_stock_transactions
WHERE item = @item AND week = @week AND firm_or_commission = @type
GROUP BY quantity
ORDER BY quantity
RETURN @Output
END
gives the same output every time it is called, despite different parameters passed. @Output does not change as expected.
Any ideas guys?
Hi,
consider my table,
s.no priority status
1 2 pending
2 3 pending
3 0 completed
4 1 pending
5 0 completed
Now, if I insert a record as,
6 1 pending
the priority must be reset as follows,
s.no priority status
1 3 pending
2 4 pending
3 0 completed
4 2 pending
5 0 completed
6 1 pending

I have a few SQL tables that use an auto incrementing integer key field, ie it has 'is identify' set to yes
The tables have been used for testing while the application was developed.
I plan to delete all data from these tables when the application goes live. Is there a way to start SQL counting from 1 again without deleting and re-creating thr tables?

How do reset identity seed on table, for example I have table that has gap in the identity such as (1,2,3,5,6, etc..) and I want reset the entire table.
Thank You,

This morning I made a change to two tables in my live system. All I did was add a new column in each called 'suspense' with a data type of bit and a default value of '0'.
When the users started using the system they noticed that the record ID numbers had reset and were starting from 1 and going up 2, 3, 4 etc. The last good id number was about 20500. The id columns are set as primary key with identity and increment of 1.
This shouldn't happen should it? Is it a bug? I never touched the ID column, just added the new one.
I have a DTS package that deletes all the records in a table and repopulates from an ACCESS table. All's well except the primary key of the target table doesn't go back to 1.
What's the syntax in T-SQL to accomplish that?
I imagine it's dropping the column and adding it back - but since it's a primary key field, regular drop/add syntax isn't working for me.
Any help here is appreciated.
Thanks,
Peter

I'm trying to create a trigger that will clear the "checked" field when all items with the same classification have been checked.
The purpose of this is to do cycle counting of inventory, which is when you count the stock levels of a proportion of stock that have the same classification.
The checked field will be used to record the date it was lasted checked and will cleared once all stock have counted, putting back into the pool of stock to be counted.
Therefore, the trigger is suppose to count the number of rows that share the same classification as the amended row, and compare that with the number of rows in that classification, that have a date in the checked date field. When the two values are the same, reset all the checked dates to blank.
But when I tested it, nothing happened ...
ALTER TRIGGER [dbo].[UDEF_Last_Checked_Reset] ON [dbo].[ASC_PMA_TBL]
AFTER INSERT
AS
BEGIN
DECLARE @PartOnly varchar(16) -- Part Number
DECLARE @Rev varchar(4) -- Part Revision
DECLARE @PartCode as varchar(2) -- Part Classification
DECLARE @Last_Checked as datetime -- Checked Date
[Code]...
