Definition
Natural join is a special type of equijoin that can be used with inner, outer and full joins. It automatically searches for all columns in both tables with the same name and type and performs an equijoin on those columns. Natural join can simplify the statement but implicit join conditions reduce code readability and understanding of relationships between tables, and are also prone to mistaken joins. PawSQL provides a risk warning for statements using natural join to avoid potential correctness issues caused by it.
