Why do i see the 'data too long for column' error in sql?

This error occurs when you try to insert data larger than the column's set size. Example:

INSERT INTO users (username) VALUES ('A very long name that exceeds column limit');

Solution:

-- Ensure data length respects the column's limit
INSERT INTO users (username) VALUES ('ShortName');

Verify your data's size before inserting or consider resizing the column.
