I recently came across a query that implements a join using just the "JOIN" keyword. On researching I saw that when using a join in SQL without specifying INNER or OUTER, the default is an INNER JOIN. I've never come across this syntax before; all the SQL I've written/read/worked with specifies INNER or some sort of OUTER (LEFT, RIGHT, FULL...). Is there any reason not to rely on the default? Is the plain JOIN widely used? What are the coding standards regarding JOIN vs. INNER JOIN?
