What are the different types of joins in Oracle SQL?

Types of Joins in Oracle SQL

In Oracle SQL, there are several types of joins that can be used to combine data from different tables:

• Inner Join: Retrieves rows that have matching values in both tables being joined.
• Outer Join: Retrieves all rows from one table and only the matching rows from the other table.
• Left Join: Retrieves all rows from the left table and the matched rows from the right table.
• Right Join: Retrieves all rows from the right table and the matched rows from the left table.
• Full Outer Join: Retrieves all rows when there is a match in either the left or right table.
• Cross Join: Produces a Cartesian product of the two tables involved in the join (all possible combinations of rows).

Each type of join serves a specific purpose and can be used based on the requirements of the query being executed.
