Answer 1

It's pretty hard to write a query to perform this when you haven't given your table schema, but something like the following:

SELECT TOP 1 Id FROM [TABLENAME] ORDER BY Id DESC

Answer 2

the last inserted value into an identity column for a connection is available using the function IDENTITY(), for example (where Id is the identity column):

INSERT INTO Test (Id, Name) VALUES (NULL,'Test');
CALL IDENTITY();
