Dear SQLiters,

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   prefix_2
....

That is when I insert a row into the table, id is already auto generated by 
SQLite. I want the filename to be auto generated too. This idea looks strange 
to me because then I do not have to insert anything, everything will be auto 
filled:

INSERT INTO A;
INSERT INTO A;

 will insert first two rows.

Roman
