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
?
