Remote MYSQL

Remote MYSQL is simple if you keep it on paper. Sara uses it for Remote MYSQL on Sara's board in a small live site.

Do Remote MYSQL once by hand. one Remote MYSQL step Sara can write from memory. Change one input. Say the new result out loud.

Without Remote MYSQL, a small live site gets messy and Remote MYSQL on Sara's board is hard to trust.

Remote MYSQL shows up in a small live site. Name Remote MYSQL on Sara's board, not “a real-world scenario”.

Remote MYSQL miss — copy-pasting Remote MYSQL without a dry-run. Fix it before you talk about advanced SQL.

After Remote MYSQL, Sara should still remember copy-pasting Remote MYSQL without a dry-run.

Close Remote MYSQL with: “If I skip it, Remote MYSQL on Sara's board goes wrong like this: copy-pasting Remote MYSQL without a dry-run.”

Exam tip

Say Remote MYSQL in one breath, then one Remote MYSQL step Sara can write from memory, then copy-pasting Remote MYSQL without a dry-run.

Remote MYSQL — sample query

-- Remote MYSQL
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;

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