Thread: Another mySQL to PostgreSQL move question

    Does PostgreSQL support something like mySQL's auto_increment tag? For
example, my entering "create table test (userid int default 0 not null
auto_increment);" in mySQL creates a table with one field that automatically
increments its value if none is specified. I have not been able to duplicate
this in PostgreSQL yet (still new...) - any help is appreciated...

I've never used MySQL, and I'm new to PostgreSQL, can you explain me
what does the following mean?

[ From the PHPBuilder MySQl/PostgreSQL report:
http://www.phpbuilder.com/columns/tim20000705.php3 ]

".. MySQL is "smart" enough to increment its auto_increment value when
you import data, whereas Postgres' sequence does not get reset when you
import data, causing all new inserts to fail..."

Does it refer to when you import data with COPY (MySQL's LOAD DATA)?
What actually happens to the sequence when you use COPY?

Thanks.
