LOAD_FILE()()

Don’t start LOAD_FILE()() (str) with jargon. Start with a LOAD_FILE str dry-run. That is the whole point.

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

LOAD_FILE()() (str) exists so Kabir can keep a LOAD_FILE str dry-run correct in a first job task.

LOAD_FILE()() (str) shows up in a first job task. Name a LOAD_FILE str dry-run, not “a real-world scenario”.

Don’t do this with LOAD_FILE()() (str): skipping the failure case for LOAD_FILE str. Interviewers spot it in ten seconds.

LOAD_FILE()() (str) is not a lonely heading. Kabir ties it to a LOAD_FILE str dry-run.

Viva for LOAD_FILE()() (str): what it is → one LOAD_FILE str step Kabir can write from memory → the mistake (skipping the failure case for LOAD_FILE str).

Exam tip

Say LOAD_FILE()() (str) in one breath, then one LOAD_FILE str step Kabir can write from memory, then skipping the failure case for LOAD_FILE str.

LOAD_FILE()() — sample query

-- LOAD_FILE()()
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;

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