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 .
Yes
Left Inner Join will be faaster

Use the Describe Command

The oracle 10g and oracle 8i there is a minor difference that is oracle 8i doesn't support flash back command once we drop the table in database the message is table dropped but we can use flashback command we can retrieve the drop table once in database
Inner join is from the inside while left out join is from the outside
inner join
Some of the functions for the alter table command in Oracle include renaming columns or rows, adding columns or rows and marking items as being read only.
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
SELECT, overall, I would view as most important.
