DATE DIFF

PlaidCloud Lakehouse does not provide a date_diff function yet, but it supports direct arithmetic operations on dates and times. For example, you can use the expression TO_DATE(NOW())-2 to obtain the date from two days ago.

This flexibility of directly manipulating dates and times in PlaidCloud Lakehouse makes it convenient and versatile for handling date and time computations. See an example below:

CREATE TABLE tasks (
  task_name VARCHAR(50),
  start_date DATE,
  end_date DATE
);

INSERT INTO tasks (task_name, start_date, end_date)
VALUES
  ('Task 1', '2023-06-15', '2023-06-20'),
  ('Task 2', '2023-06-18', '2023-06-25'),
  ('Task 3', '2023-06-20', '2023-06-23');

SELECT task_name, end_date - start_date AS duration
FROM tasks;

task_name|duration|
---------+--------+
Task 1   |       5|
Task 2   |       7|
Task 3   |       3|
