Maven

Don’t start Maven with jargon. Start with a Maven dry-run. That is the whole point.

Maven on the board — one Maven step Arun can write from memory. Then say what a Maven dry-run looks like after.

Maven exists so Arun can keep a Maven dry-run correct in a campus project.

Maven shows up in a campus project. Name a Maven dry-run, not “a real-world scenario”.

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

After Maven, Arun should still remember copy-pasting Maven without a dry-run.

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

Exam tip

Say Maven in one breath, then one Maven step Arun can write from memory, then copy-pasting Maven without a dry-run.

Maven — sample query

-- Maven
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;

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

Short notes

DefMaven — Arun uses it for a Maven dry-run in a campus project.
RuleMaven → one Maven step Arun can write from memory.
RememberMaven + InnoDB (a campus project).
UseMaven in a campus project (a Maven dry-run).
TrapMaven — copy-pasting Maven without a dry-run.
ExMaven → a Maven dry-run.

-- Maven 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;
