I need to store numbers which contain '0' as the first digit like '001', '01' .

A little history.  A DNA clone_id is denoted by '894001A01.x1'.  I 
need to sort  clone_id, and have broken it down into its meaningful 

project:	894
plate:		001
plate row:	A
plate column: 	01
read:		x
ver:		1

CREATE TABLE clone_fasta (
project integer NOT NULL,
plate integer NOT NULL,
p_row char(1) NOT NULL,
p_column integer NOT NULL,
read char(1) NOT NULL,
ver integer NOT NULL,
length integer NOT NULL,
seq text NOT NULL,
PRIMARY KEY (project,plate,p_row,p_column,read,ver)

Unfortunately, storing these numbers as integers converts 001 ->1, 
which I can't use.

How does one store a number like '001'?
