SQL Interview

Interview (sql) is a SQL idea you prove with a fail-list view, not with a slogan.

For Interview (sql), InnoDB is in play. Don’t blame it until you have traced a fail-list view.

Interview (sql) exists so Vikram can keep a fail-list view correct in teachers’ report.

Interview (sql) shows up in teachers’ report. Name a fail-list view, not “a real-world scenario”.

If a fail-list view breaks under Interview (sql), check trying to UPDATE a non-updatable view first.

Place Interview (sql) next to nearby SQL work — CREATE VIEW fail_list AS … is the link.

Close Interview (sql) with: “If I skip it, a fail-list view goes wrong like this: trying to UPDATE a non-updatable view.”

Exam tip

Say Interview (sql) in one breath, then CREATE VIEW fail_list AS …, then trying to UPDATE a non-updatable view.

SQL Interview — sample query

-- SQL Interview
CREATE TABLE demo (
  id INTEGER PRIMARY KEY,
  label TEXT NOT NULL,
  qty INTEGER DEFAULT 0
);
INSERT INTO demo (id, label, qty) VALUES
  (1, 'alpha', 2),
  (2, 'beta', 5);
SELECT label, qty FROM demo WHERE qty >= 2 ORDER BY qty DESC;

SQL Interview: create two demo rows, then SELECT qty >= 2 ordered. Say which labels come back.
