Howdy:
I am coming from the Windows world, and Microsoft SQL variants in
particular. Both Access and SQL Server have autoincrement data types --
I understand that Postgresql has "sequences" which do the same thing,
but I can't find any documentation on them. I have browsed all the
online documentation that comes with Postgresql, and can't find anything
about it. Could someone point me to some docs that would explain how to
use sequences?
I have a similar question about oid's. I am not sure what they are --
from their name, I would guess that they are autoassigned, unique
identifiers for each row in a table. Is that correct? If so (or even
if not), how do I create and use them. Any documentation that addresses
oid usage specifically? I am confused because oid's seem to be to
substitute for the BLOB data type which is available in other RDBMS's.
If you post a reply to this, could you also cc: to
