Question

I have the following table in mysql:

A B C D
1 2 3 4

And I want to transorm it into

<title1> <title2>
A        1
B        2
C        3
D        4

I only found complicated stuff, does anyone know of a simple staright forward function that does this?

Answer 1

select 'A' as title1, a as title2 from table union all
select 'B' as title1, b as title2 from table union all
select 'C' as title1, c as title2 from table union all
select 'D' as title1, d as title2 from table
