join of two or more tables that returns only those rows that satisfy the join condition.
Outer Joins : An outer join extends the result of a simple join. An
outer join returns all rows that satisfy the join condition and also returns some or all of those rows from one table for which no rows from the other satisfy the join condition
join of two or more tables that returns only those rows that satisfy the join condition.
Outer Joins : An outer join extends the result of a simple join. An
