Show Users

If you can teach Show Users using a Show Users dry-run, you know it. If you only know the heading, you don’t.

Keep Show Users small. Meera should finish a Show Users dry-run in a few lines, not a 40-line dump.

Skip Show Users and copy-pasting Show Users without a dry-run shows up in a small live site.

Use Show Users when a Show Users dry-run must stay clear. If a simpler SQL step works, use that instead.

Show Users trap — copy-pasting Show Users without a dry-run. Meera loses marks for that every viva.

After Show Users, Meera should still remember copy-pasting Show Users without a dry-run.

Close Show Users with: “If I skip it, a Show Users dry-run goes wrong like this: copy-pasting Show Users without a dry-run.”

Exam tip

Say Show Users in one breath, then one Show Users step Meera can write from memory, then copy-pasting Show Users without a dry-run.

Show Users — sample query

-- Show Users
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;

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