should generate AA, AB, AC, AD,...BA. Your help in this regard is highly appreciated.
First of all, these aren't going to be "auto"-incremented. If you're hoping to have the database generate these codes automatically, it's not going to happen. The best you can do is generate these codes yourself. Start by creating a LETTERS table:
create table letters ( letter char(1) not null primary key ); insert into letters values ('A'),('B'),('C'),('D'),('E'),('F'),('G') ,('H'),('I'),('J'),('K'),('L'),('M'),('N') ,('O'),('P'),('Q'),('R'),('S'),('T'),('U') ,('V'),('W'),('X'),('Y'),('Z');
Now you can easily generate any range of codes like this:
select t1.letter||t2.letter from letters as t1 cross join letters as t2 where t1.letter||t2.letter between 'AA' and 'BA'
