I wouldn't go that far. I build updatable views, select * from them,
cycle through the fields getting name / type and build generic forms to
let the user edit / insert new records.
It allows me to reuse the same basic chunk of code over and over.
Of course, it's select * on a view, not a table, so I set the order when I
create the view.
Now, using select * and ASSUMING the order of the variables in your
application code is a punishable offense, but as long as you determine the
name / type of the fields after the select * it's not so bad.
