You can use GROUP_CONCAT

SELECT GROUP_CONCAT(Serial_number ) FROM data;

Note: GROUP_CONCAT has a maximum length.

---

select concat(col1, ',' , col2, .....) from tbl;

---

i think you can use something like phpmyadmin and save a select statement to file, then select csv as the file type..

what you want is GROUP_CONCAT()

SELECT GROUP_CONCAT(Serial_number) FROM data

yields:

0001,0002,0003,...
