Answer 1

In MySQL:

SELECT LAST_INSERT_ID();

In SQL Server:

SELECT SCOPE_IDENTITY();

In Oracle:

SELECT SEQNAME.CURRVAL FROM DUAL;

In PostgreSQL:

SELECT lastval();

(edited: lastval is any, currval requires a named sequence) Note: lastval() returns the latest sequence value assigned by your session, independently of what is happening in other sessions.
