In a LEFT JOIN, what happens to a row in the left table that has no matching row in the right table?

In a LEFT JOIN, every row from the left table shows up in the result. If there isn’t a matching row in the right table, the query fills the right-side columns with NULLs, so that left row still appears but with NULL values for the right table’s fields. If there were matches, you’d see data from the right side; if there are no matches, you don’t drop the left row or error out—you just get NULLs on the right.
