What is the auxiliary constructs in sql

Question

I need some help to know what's the auxiliary constructs, and examples in the auxiliary constructs

Answer 1

Like everyone else, I am a bit puzzelled by "auxiliary constructs", but since, as michaels and Dave demonstrated, the update can be done in a single statement, I would guess that perhaps the:
UPDATE Is_member
SET Organization= 'EU11'
WHERE Organization= 'NATO';query is an auxiliary construct, and perhaps even the query:
UPDATE Is_member
SET Organization= 'EU'
WHERE Organization= 'EU11'; On the other hand, another method with a real construct (not sure if it is auxiliary or not) would be something like:
CREATE TABLE member_temp AS
SELECT * FROM is_member WHERE 1=2;
INSERT INTO member_temp
SELECT 'NATO' FROM is_member
WHERE organization = 'EU';
INSERT INTO member_temp
SELECT 'EU' FROM is_member
WHERE organization = 'NATO';
TRUNCATE TABLE is_member;
INSERT INTO is_member
SELECT * FROM member_temp;but that is a really bad way to do it.
