App

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

For App, an index is in play. Don’t blame it until you have traced a App dry-run.

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

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

If a App dry-run breaks under App, check skipping the failure case for App first.

After App, Farhan should still remember skipping the failure case for App.

One breath for App, then a App dry-run, then skipping the failure case for App. Sit down.

Exam tip

For App: definition + a campus project + one failure.

App — sample query

-- App
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;

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

Short notes

DefApp — Farhan uses it for a App dry-run in a campus project.
RuleApp → one App step Farhan can write from memory.
RememberApp + an index (a campus project).
UseApp in a campus project (a App dry-run).
TrapApp — skipping the failure case for App.
ExApp → a App dry-run.

-- App 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;
