Show Tables

Show Tables is simple if you keep it on paper. Sara uses it for a Show Tables dry-run in a viva board.

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

Skip Show Tables and copy-pasting Show Tables without a dry-run shows up in a viva board.

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

If a Show Tables dry-run breaks under Show Tables, check copy-pasting Show Tables without a dry-run first.

Show Tables is not a lonely heading. Sara ties it to a Show Tables dry-run.

Viva for Show Tables: what it is → one Show Tables step Sara can write from memory → the mistake (copy-pasting Show Tables without a dry-run).

Exam tip

For Show Tables: definition + a viva board + one failure.

Show Tables — sample query

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