In How many ways we can use Inner join ?
as well as Left Join ?
In a LEFT join, all the records from the first table are kept, and only those records from the second table that match a record in the first table are kept.
In an INNER join, only records with a match across both tables will be kept.

yes it is possible to join with column name i mean you just have Key column in both tables on which you make your join.
