is bad form. Always use a new and unique alias, like m1. How does this work:
SELECT '2', substr(m,2) AS m1

Tnx. I think everybody agrees that "substr(m,2) as m" is bad form. And all the database engines get the same consistent answer when you avoid the bad form and use "substr(m,2) as m1" instead. The question is, what should the database engine do when the programmer disregards sounds advice and uses the bad form anyhow?
