You received an invitation to an amazing party. Now you need to write an insert statement to add yourself to the table of participants.
participants table schema
- name (string)
- age (integer)
- attending (boolean)
NOTES:
- Since alcohol will be served, you can only attend if you are 21 or older
- You can't attend if the attending column returns anything but true
NOTE: Your solution should use pure SQL. Ruby is used within the test cases just to validate your answer.
Solution:
INSERT INTO
participants
VALUES
('Daco', 99, true);
--
SELECT
*
FROM
participants;
Result:
name | age | attending |
Alex | 22 | true |
Sam | 24 | true |
Daco | 99 | true |
