Which is not a type of join in T-SQL?(a) Equi-join(b) Natural join(c) Outer join(d) Cartesian joinThe question was posed to me in an online quiz.My question is taken from Joins in section Laying the Foundation of SQL Server

Answer» RIGHT answer is (b) Natural join

The explanation is: A NATURAL JOIN is an INNER join where the RDBMS AUTOMATICALLY selects the join columns based on common columns names. Some RDBMS vendors, LIKE Oracle but not SQL Server, implement a NATURAL JOIN operator.
