get @@identity from several records

Hi,

I was wondering if you can help.

I am running an sql query that creates several new records based on a select query. In other words duplicating some existing records in a table.

What I need to do is after I have created these new records update a field in each of them.

Any ideas how I can retrieve all of their ids at insertion and then use them to update a field in each of them?

Ideally I would like to use @.@.identity and datareaders with vb.net.

Cheers

You need to put all the TSQL into a stored procedure. After each insert use SCOPE_IDENTITY() to get the id of the record just inserted.

|||Decorate your table with a new column, let's call it "batchid". It could be a uniqueidentifier.

DECLARE @.batchid uniqueidentifier

SELECT @.batchid=newid()

--The insert

INSERT INTO table (column1,column2 ..... , batchid)
SELECT column1,column2......, @.batchid FROM table WHERE...

--Retrieve the new id:s

SELECT id FROM table WHERE batchid=@.batchid

But it's quite likely that you can insert the correct data directly, instead of having to update it afterwards.

INSERT INTO table (column1,column2 ..... , column15)
SELECT column1,column2......, @.thenewvalueforcolumn15 FROM table WHERE...|||

Although I like the solution of gunteman, I'm just wondering why you can't update the field in the INSERT statement?

Hi,

Thanks for your help. But i would really like to update the field in the insert statement.

Any suggestions?

I described it above. If you want to set the new value directly, just include it in your insert statement.

INSERT INTO table (column1,column2 ..... , column15)
SELECT column1,column2......, @.thenewvalueforcolumn15 FROM table WHERE...

If you show us your INSERT and UPDATE statement, we could help you combine them.
