Re: Return serial from insert

You misunderstand.  I wrote "...get the nextval() from the sequence and use
that for the NEW INSERT..."

If you table definition is like:

create "myTable"
(
    id serial primary key,
    foo char(5),
    bar numeric(10,2)
)

The sequence created would be "myTable_id_seq".  To do what you want:

1) get the nextval -- (select nextval("myTable_id_seq"::text);)
2) name the image file using the value from nextval
3) insert the record using the value from nextval: (insert into "myTable"
(id,foo,bar) values (valueFromNextVal,'foob',5.4);)

2 & 3 are interchangeable
