[Dbix-class] single field in resultset?

Michael,

See the 'columns' attribute or the 'select / as' attribute combo.  For
example:

$schema->resultset('Foo')->search(
  {  id =3D> { -in =3D> [ 1, 2, 3 ] }  },
  {  columns =3D> [ 'id', 'title' ] }
);

It's covered in more detail in the ATTRIBUTES section of the
DBIx::Class::ResultSet perldocs.  There are also some examples in
DBIx::Class::Manual::Cookbook under 'Using specific columns'.

Good luck,
Mark
