Inserting data

Write the query to add a new record with INSERT.

Inserting data

With INSERT we add a new record to the table. Columns and values go in parentheses, separated by commas.

INSERT INTO notes (id, title, body)
VALUES (3, 'Market', 'Süt, ekmek');

This adds one row to the notes table.

The values given with VALUES are inserted into notes as new rows.

Inserting data — details

Create is the C in CRUD. After INSERT INTO comes the table name, columns in parentheses, then VALUES and the values. Text values go in single quotes.

Practice Inserting data

Insert into notes the row id=3, title='Market', body='Milk, bread'.

Starter code

query.sql
-- add a new note
INSERT INTO notes (id, title, body)
VALUES

Sample solution

query.sql
INSERT INTO notes (id, title, body)
VALUES (3, 'Market', 'Süt, ekmek')
