INSERT INTO SELECT Oracle PL/SQL faux pas

I’ve recently stumbled upon a bug that came down to the following piece of code:

INSERT INTO TABLE_A (
   SELECT ALPHA,
          GAMMA,
          BETA
   FROM TABLE_B
)
;

This is an INSERT query with respect to the column order of the table. In general the order of the columns in the table shouldn’t be important on our queries therefore the following more robust version of INSERT is guarding against ambiguity relying on the column order:

INSERT INTO TABLE_A (
   ALPHA,
   BETA,
   GAMMA
) VALUES
(  SELECT ALPHA,
          BETA,
          GAMMA
   FROM TABLE_B
)
;
