Thanks for the replies,
I have one question regarding this comment...
"You also need to add a DEFAULT expression and optionally
make the sequence owned by the column:"
What difference does it make if a table "owns" a sequence of not?...does this contraint the use of the sequence to ONLY that one table?
The sequence will only be used to auto-increment the id column in order to have an automatic primary key. Could I then somehow use the sequence for all tables which need this?
yours,
Rob
please, don't use top-posting. It messes up the order of the messages.
The sequenced that is OWNED BY a column can of course be used
by other columns in other tables. You can specify nextval('same sequence')
for any number of columns' default value.
