Explain an outer join?..

Answer / vamsikrishnamraju

An outer join operation returns all the rows returned by an
inner join plus all the rows from one table that do not
match any row from the other table. An outer join can be
left, right, or full, depending on whether rows from the
left, right, or both tables are retained
