Question

get id of last inserted record, .net one command

Asked by: NewtonianB

I'm inserting a record in my table2 and i'd like the id to be returned to be upon the insert. I am executing this from an asp.net application so if possible I'd like to limit the number of requests.
I was reading I could issue a SELECT LAST_INSERT_ID(); right after the insertion but I am afraid this could cause serious fatalities if I get several requests at once.
Are there any other options to limit number of commands I have to issue from .net?

table2
id int autoincrement
name varchar

You should be able to do multiple command from .net

the SQL command to get the last insert id is
SELECT @@IDENTITY

Select Scope_Identity() is prefered as it selects the last one from the connection doing the calling.

It should avoid the concurrency problem you fear.

create a stored function
function inserts the record and return the value of identity, or 0 in case of any error
and to get the identity, you can use Select Scope_Identity() or SELECT @@IDENTITY as stated in previous posts...

>>create a stored function
function inserts the record <<
I trust you mean a Stored Procedure and not a User Defined Function.
