Longtext

Don’t start Longtext with jargon. Start with a Longtext dry-run. That is the whole point.

Longtext order — meaning → one Longtext step Neha can write from memory → one limit. Dumping ten features helps nobody.

Longtext exists so Neha can keep a Longtext dry-run correct in lab hour.

Longtext shows up in lab hour. Name a Longtext dry-run, not “a real-world scenario”.

Longtext miss — only reciting the name of Longtext. Fix it before you talk about advanced SQL.

Longtext is not a lonely heading. Neha ties it to a Longtext dry-run.

Viva for Longtext: what it is → one Longtext step Neha can write from memory → the mistake (only reciting the name of Longtext).

Exam tip

For Longtext: definition + lab hour + one failure.

Longtext — sample query

-- Longtext
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;

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