Re: Creating Primary Key after CREATE TABLE: Is Sequence created?

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.
