Left Inner Join will be faaster
One is inner the other is not... Plum
Inner join is from the inside while left out join is from the outside
yes, we do have inner join command in oracle. Inner Join is used to combine related tuples from two relations.It allows to evaluate a join condition between attributes of the relations on which join is undertaken .
inner join
In SQL you just keep adding JOINs; select * from Table1 inner join Table2 on (Table2.key = Table1.Key) inner join Table3 on (Table3.key = Table1.Key) inner join Table4 on (Table4.key = Table1.Key) inner join Table5 on (Table5.key = Table1.Key) inner join Table6 on (Table6.key = Table1.Key) and so on.
Inner Join
Inner join refers to the join where records that match the where condition in both tables are only fetched. Ex: SELECT A.field1, A.field2, B.field3, B.field4 FROM Table1 A, Table2 B WHERE A.field1 = B.field3 This is an inner join.
If you do not explicitly state the type of join (inner, outer, left, right) then the database will handle the query as an inner join query even though you did not specify it as such. All multi-table queries are inner joins unless specified otherwise.
Joins refer to the combination of related records to form a relation . There are six types of joins in database . Types of joins are cross join, natural join , right join , left join ,Inner join, Outer join.INNER JOINOUTER JOINLEFT JOINRIGHT JOINNATURAL JOINCROSS JOINIn special cases a table can join to itself (SELF JOIN)

Assuming you're joining on columns with no duplicates, which is by far the most common case; An inner join of A and B gives the result of A intersect B, i.e. the inner part of a venn diagram intersection. Wheres as an outer join of A and B gives the results of A union B, i.e. the outer parts of a venn diagram union.
