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 RepliesAm working on sql database table shifting to new database tables. Am getting the following error while truncating the tables:-
Cannot truncate table 'orderItem' because it is being referenced by a FOREIGN KEY constraint.How can i remove all the items in the table if i found this error.
Here is my issue I am new to 2005 sql server, and am trying to take my old data which is exported to a txt file and import it to tables in sql. The older database is non relational, and I had made several exports for the way I want to build my tables. I built my packages fine and everything is working until I start building relationships. I remove my foreign key and the table with the primary key will get updated for the package again. I need to update the data daily into sql, and once in it will only be update from the package until the database is moved over.
It will run and update with a primary key until I add a foreign key to another database.
Here is my error when running the package when table 2 has a foreign key.
[Execute SQL Task] Error: Executing the query "TRUNCATE TABLE [consumer].[dbo].[Client] " failed with the following error: "Cannot truncate table 'consumer.dbo.Client' because it is being referenced by a FOREIGN KEY constraint.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
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 RelatedThe parent table has the column OrderID which is the primary key. There is a unique non-clustered index in the same table with the same column and some included ones. A child table references the parent table on the OrderID column. Unfortunatelly, in the sys.foreign_keys table the index that has been used to acomplish the referential integrity is the unique non-clustered one instead of the primary key (which is the clustered index as well).
This is causing issues in some maintenance tasks where we need to disable all the indexes of the table apart from the clustered index. Disabling these indexes leeds to disabling the not properly configured foreign key as well. Maybe dropping the index create the constraint again and then recreate the index is a workarround but I wish to have something more elegant and future proof.

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
I 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

Hi
I am trying to update tables "Table A" & " TableB" with a new value for a particular column1. Now "TableA" contains a foreign key "FK1" defined on it and is referencing another table "Table B" containing the similar column "Column1"
Because of this constraint I was not able to update TableA and TableB. My question is
1) If i wanted to go ahead with this update, what are the possible ways?
2) If only solution is to drop the constraint. Then How do i know the definition for this particular Foreign key, i mean it may refer some columns in Table B. I wanted to know the complete definition of it so that i can rebuild the constraint after the update. Right now i can see only the constraint name when i use sp_help TableA. But how do i know the complete reference made by this foreign key.
Early reply is much appreciated
Thanks!

I am in the middle of taking course 2073B €“ Programming a Microsoft SQL Server 2000 Database. I noticed that in Module9: Implementing User-Defined Functions exercise 2, page 25; step 2 is not returning the correct answer.
Select employeeid,name,title,mgremployeeid from dbo.fn_findreports(2)
It returns manager id for both 2 and 5 and I think it should just return the results only for manager id 2. The query results for step 1 is correct but not for step 2.
Somewhere in the code I think it should compare the inemployeeid with the previous inemployeeid, and then add a counter. If the two inemployeeid are not the same then reset the counter. Then maybe add an if statement or a case statement. Can you help with the logic? Thanks!

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?
-smcirish
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,

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.

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.

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,
Kiran Suthar.
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 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!

I have a created a database with nearly 20 tables in it, so I cannot post all of my statements. I am having an issue though with two tables' referential integrity when it comes to foreign key constraints.

I have tried making an update trigger but it does not work.
i have a publication that is composed of
many articles. The publication is composed of many

lets say. article 1 synchonizes first, then article 3, then article 2
Hi
I am attempting to write a DTS package that copies the data across from one instance of a db on a test server to a second instance on to the live server. It has to replace all the exisiting date so I can't append. Unfortunately, the package keeps giving me errors all of the type "unable to truncate tbl due to foreign key constraints". Is there a way round this?
