GUI

GUI sits in a first job task. Farhan’s job is GUI on Farhan's board. Write that first.

For GUI, InnoDB is in play. Don’t blame it until you have traced GUI on Farhan's board.

GUI exists so Farhan can keep GUI on Farhan's board correct in a first job task.

GUI shows up in a first job task. Name GUI on Farhan's board, not “a real-world scenario”.

Don’t do this with GUI — copy-pasting GUI without a dry-run. Interviewers spot it in ten seconds.

After GUI, Farhan should still remember copy-pasting GUI without a dry-run.

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

Exam tip

Board: GUI on Farhan's board. Dry-run GUI. Name the trap: copy-pasting GUI without a dry-run.

GUI — sample query

-- GUI
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;

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

Short notes

DefGUI — Farhan uses it for GUI on Farhan's board in a first job task.
RuleGUI → one GUI step Farhan can write from memory.
RememberGUI + InnoDB (a first job task).
UseGUI in a first job task (GUI on Farhan's board).
TrapGUI — copy-pasting GUI without a dry-run.
ExGUI → GUI on Farhan's board.
