OK, thats cool... I have found an example in "sql-createsequence.html"
CREATE SEQUENCE serial START 1;
INSERT INTO distributors VALUES (nextval('serial'), 'nothing');
But there is one thing not clear:
Du I need to create a SEQUENCE for each table or do I need only ONE of

Thanks, Greetings and nice Day/Evening
