Hi David and John - Thank you for your answers on the SERIAL, SEQUENCE and thus PRIMARY KEY. I did not realize there was a column of type SERIAL that creates a SEQUENCE. However, now I have a different question. Is it possible to create a column of type SQL:2011 types (INTEGER or such) and then connect a SEQUENCE to it and make that column a PRIMARY KEY - without creating a column of type SERIAL? It seems column of type SERIAL is specific to Postgres and will make my script Postgres dependent? Just in case I decide to go to MySQL. Most likely not, but just wanted to manage to SQL:2011. Thank you again. -- View this message in context: http://postgresql.1045698.n5.nabble.com/Creating-Primary-Key-after-CREATE-TABLE-Is-Sequence-created-tp5772633p5772642.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
