Azure MySQL

Priya only reaches for Azure MySQL when a Azure MySQL dry-run has to stay correct in a campus project.

Azure MySQL order: meaning → one Azure MySQL step Priya can write from memory → one limit. Dumping ten features helps nobody.

Skip Azure MySQL and skipping the failure case for Azure MySQL shows up in a campus project.

Priya ships Azure MySQL in a campus project. That is the use case worth saying.

Don’t do this with Azure MySQL — skipping the failure case for Azure MySQL. Interviewers spot it in ten seconds.

After Azure MySQL, Priya should still remember skipping the failure case for Azure MySQL.

Viva for Azure MySQL: what it is → one Azure MySQL step Priya can write from memory → the mistake (skipping the failure case for Azure MySQL).

Exam tip

For Azure MySQL: definition + a campus project + one failure.

Azure MySQL — sample query

-- Azure 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;

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