minute()

minute() is simple if you keep it on paper. Sara uses it for minute on Sara's board in a campus project.

minute() on the board: one minute step Sara can write from memory. Then say what minute on Sara's board looks like after.

Skip minute() and copy-pasting minute without a dry-run shows up in a campus project.

Sara ships minute() in a campus project. That is the use case worth saying.

minute() trap — copy-pasting minute without a dry-run. Sara loses marks for that every viva.

Place minute() next to nearby SQL work — one minute step Sara can write from memory is the link.

One breath for minute(), then minute on Sara's board, then copy-pasting minute without a dry-run. Sit down.

Exam tip

For minute(): definition + a campus project + one failure.

minute() — sample query

-- minute()
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;

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