INSERT Record

If you can teach INSERT Record using INSERT Record on Sara's board, you know it. If you only know the heading, you don’t.

For INSERT Record, the query planner is in play. Don’t blame it until you have traced INSERT Record on Sara's board.

Without INSERT Record, lab hour gets messy and INSERT Record on Sara's board is hard to trust.

Sara ships INSERT Record in lab hour. That is the use case worth saying.

Don’t do this with INSERT Record — only reciting the name of INSERT Record. Interviewers spot it in ten seconds.

After INSERT Record, Sara should still remember only reciting the name of INSERT Record.

Close INSERT Record with: “If I skip it, INSERT Record on Sara's board goes wrong like this: only reciting the name of INSERT Record.”

Exam tip

Board: INSERT Record on Sara's board. Dry-run INSERT Record. Name the trap: only reciting the name of INSERT Record.

CREATE TABLE products (id INTEGER PRIMARY KEY, name TEXT, price REAL);
INSERT INTO products (id, name, price) VALUES
  (1, 'Mouse', 499),
  (2, 'Keyboard', 999);
SELECT * FROM products;
