Hi Terence,
I think your problem lies in your SELECT *
If you look at the columnheaders below you get category_id twice.
I guess you have to specify your columns with aliases.

Hi Johan,
Nope, if I change the column name to category_id1 then it's okay. See
this: (apologies for the previous typo in the reproducible script)
create table `ticket_master` (
`ticket_id` int (5) NOT NULL AUTO_INCREMENT ,
`category_id` int (5) NULL,
PRIMARY KEY ( `ticket_id` ));
Query OK, 0 rows affected
create table `category_master` (
`category_id` int (5) NOT NULL AUTO_INCREMENT ,
`category_name` varchar (20) NULL,
PRIMARY KEY ( `category_id` ));
Query OK, 0 rows affected
CREATE VIEW `v_tickets` AS
(
SELECT * FROM ticket_master tm, category_master cm
WHERE tm.category_id = cm.category_id
);
ERROR 1060 : Duplicate column name 'category_id'
alter table `category_master` ,change `category_id` `category_id1` int
(5) NOT NULL AUTO_INCREMENT ;
CREATE VIEW `v_tickets` AS
(
SELECT * FROM ticket_master tm, category_master cm
WHERE tm.category_id = cm.category_id1
);
Query OK, 0 rows affected
