table to populate the columns based on the just created ID. Is this what you
suggested?

Couldn't you have it access a view which adds the columns by calculation
rather than the raw table? (and if you have some tables

One question I have, couldn't you just omit the fileName column from the

I will use this table as a manager. There will be multiple columns holding various file names. The

I would like to use primary key as a way to create unique column entry:
CREATE TABLE A( id INTEGER PRIMARY KEY, fileName TEXT NOT NULL)
such that file name is always prefix followed by the ID for the content to be:
ID fileName
1 prefix_1
2
Solved with trigger, but I can not use NOT NULL for the fileName column:
CREATE TRIGGER AAA AFTER INSERT ON A
BEGIN
UPDATE A SET fileName = 'prefix'||NEW.id WHERE id=NEW.id;
END;
INSERT INTO A (id) VALUES (NULL);
INSERT INTO A (id) VALUES (NULL);
INSERT INTO A (id) VALUES (NULL);
...
