- Casting Date Values
Now let’s create a sample table in PostgreSQL and perform multiple dates operations on them:
Create table.
CREATE TABLE events (
event_id SERIAL PRIMARY KEY,
event_name VARCHAR(100),
event_date DATE
);
Insert data into table.
INSERT INTO events (event_name, event_date) VALUES
('Event 1', '2023-01-15'),
('Event 2', '2023-02-20'),
('Event 3', '2023-03-25'),
('Event 4', '2023-04-10'),
('Event 5', '2023-05-05');
The table is created successfully:
