Register for the Party (SQL for Beginners #3)

by daco2020 2022. 6. 5.

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
