I'm using the latest stable - and recommended - release of MySQL, the 3.23 version. What bugs me is that the UNION operation is only implemented in MySQL 4.0 (as per http://www.mysql.com/doc/U/N/UNION.html
), while this one is still alpha. I'm not too sure about using it, especially just to accomodate ONE query. Are there any alternatives? Anything that might give the same result as UNION? Bascially, what I need is a query that merges two columns into one.
