Is there a function I can use to retrieve the unique id (talking about primary key) of the last insertion into a table?

The issue is that I need to insert the ID of the last insertion as a reference ID in another table immediately.As it appears to me I may have to execute a select query to fetch this needed ID but that appears a waste of valuable time to me.

Pardon me.I am new to ADO.Could you show me how to do this with ado, particularly how to retrieve it from the record set (I suppose).

I mean will the result be the first item in a field collection or what?

it returns single value from you table ,lets say your table has 5 record with latest identity 5 , then it return latest Identity value.

Solution 2

Hello ,

You can use SCOPE_IDENTITY() to get the latest Primary Key or Identity value.
try like this way

declare @id int
insert into tblname values(val1, val2)
select @id=SCOPE_IDENTITY()

thanks

it does not return any field collection , it only returns the last inserted primary key (a single value) .
