The main difference between Self Join and Equi Join is that In Self Join we join one table to itself rather than joining two tables. Both Self Join and Equi Join are types of INNER Join in SQL, but there is the subtle difference between two. Any INNER Join with equal as join predicate is known as Equi Join. difference between equi join and inner join An equijoin is a join with a join condition containing an equality operator. An equijoin returns only the rows that have equivalent values for the specified columns. An inner join is a join of two or more tables that returns only those rows (compared using a comparison operator) that satisfy the join condition.

If it's not an equijoin, then it's usually called a theta join, although to be precise, an equijoin is just one of the possible theta joins; other theta joins use less than, less than or equal, etc. , as the comparison operator. difference between equi join and inner join What is the differecne between equijoin and innerjoin and natural join. . Is there any difference. . Answer sandy Inner join can have equality () and other operators (like, ) in the join condition. Equi Join means you only use equality () comparator in join condition, regardless of join type. Inner Join allows greater (), lesser () in join condition. If you only use equality () comparator in an Outer Join statement, its also called an Equi Join. Related QuestionsMore Answers Below.
