What is the equivalent function in oracle for if function in mysql?

The equivalent function in Oracle for the IF function in MySQL is the CASE statement. The CASE statement allows you to perform conditional logic and return different values based on the specified conditions. Here is an example of how the CASE statement can be used in Oracle:

1
2
3
4
5
6
7

SELECT column1,
       CASE
           WHEN condition1 THEN result1
           WHEN condition2 THEN result2
           ELSE result3
       END AS result
FROM table_name;

In the above statement, you can specify multiple conditions and their corresponding results. If none of the specified conditions are met, the ELSE clause specifies the default result value.
