To perform a join in Oracle SQL, you can use the JOIN keyword in your SELECT statement to combine rows from two or more tables based on a related column between them. Here is a basic example of how to do a join in Oracle SQL:

SELECT t1.column1, t2.column2
FROM table1 t1
JOIN table2 t2 ON t1.related_column = t2.related_column;

In this example, table1 and table2 are the names of the tables you want to join, t1 and t2 are aliases for those tables, and related_column is the column that the two tables have in common. You can specify the columns you want to display in the SELECT statement, and use the ON keyword to specify the join condition between the tables.

There are different types of joins in SQL, such as INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN. You can use these different join types based on your needs and the relationship between the tables.
