Different SQL JOINs
Before we continue with examples, we will list the types of JOIN
you can use, and the differences between them.
JOIN:
Return rows
when there is at least one match in both tables
LEFT JOIN:
Return all
rows from the left table, even if there are no matches in the right table
RIGHT JOIN:
Return all
rows from the right table, even if there are no matches in the left table
FULL JOIN:
Return rows
when there is a match in one of the tables
