What is the method for performing a join query in Oracle?

In Oracle, joining tables can be achieved by using the JOIN keyword in SQL statements. Common ways of joining tables include:

  1. Join that only includes rows that have matching values in both tables.
SELECT columns
FROM table1
INNER JOIN table2
ON table1.column = table2.column;
  1. Merge two tables based on a common column and include all rows from the left table.
SELECT columns
FROM table1
LEFT JOIN table2
ON table1.column = table2.column;
  1. – Right outer join
SELECT columns
FROM table1
RIGHT JOIN table2
ON table1.column = table2.column;
  1. Full outer join
  2. No suitable response
SELECT columns
FROM table1
FULL JOIN table2
ON table1.column = table2.column;

The above are common methods for performing join queries in Oracle, and the appropriate join type can be selected based on the specific situation to meet the query needs.
