Answer 1

In Oracle 12c it is now easier to rearrange columns logically. It can be achived by making column invisible/visible.If you change a invisible column to visible , the column will appear last in the odering.

Consider Using Invisible Columns

Create wxyz table:

CREATE TABLE t ( w INT,
y VARCHAR2, z VARCHAR2, x VARCHAR2

);

rearrange the x column to the middle:

ALTER TABLE wxyz MODIFY (y INVISIBLE, z INVISIBLE); ALTER TABLE wxyz MODIFY (y VISIBLE, z VISIBLE);

DESCRIBE wxyz;

Name

w

x

y

z
