When I implemented a DBI interface for pthrlib, I added a "serial"
method. This is an extension to the basic Perl DBI, but very useful.
Example (in pseudocode):
Table: create table employees (empid serial, name text, salary int);
let query = dbh#prepare "insert into employees (name) values ('John Smith')";;
query#execute;;
let empid = query#serial ("employees_empid_seq");; (* returns, eg., 1 *)
The argument to serial is the sequence name, required for PostgreSQL,
but can be ignored on other databases.
Rich.
