REPEAT()()

Don’t start REPEAT()() (str) with jargon. Start with REPEAT str on Kabir's board. That is the whole point.

For REPEAT()() (str), an index is in play. Don’t blame it until you have traced REPEAT str on Kabir's board.

Skip REPEAT()() (str) and only reciting the name of REPEAT str shows up in a first job task.

Kabir ships REPEAT()() (str) in a first job task. That is the use case worth saying.

REPEAT()() (str) trap — only reciting the name of REPEAT str. Kabir loses marks for that every viva.

REPEAT()() (str) is not a lonely heading. Kabir ties it to REPEAT str on Kabir's board.

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

Exam tip

For REPEAT()() (str): definition + a first job task + one failure.

REPEAT()() — sample query

-- REPEAT()()
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;

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