FETCH_2D is the "core" of my proposal. It's like the

the second level:
$result[tablename][columname]
Not sure how real world useful this is. What I have seen more is a
need to build tree style structures. This would require knowing the
FK's or allowing the user to specify the tree structure they want.
This sort of thing is supported by C#'s LINQ.
Columns that don't result from a table are added to a "null
base" (work
title). The default "null base" is the first level array:
$result[computedcolumn]
The connection attribute ATTR_2D_NULLBASE (work title) defines an
alternative "null base":
$result[nullbase][computedcolumn]
Why not use an empty string aka null casted to a string. That way you
will never run into a situation where someone has called their table
"nullbase". It will also make it immediatly clear to anyone that this
array key is special.
