## Description

https://leetcode.com/problems/calculate-special-bonus/

SQL Schema

Table: `Employees`

```+-------------+---------+
| Column Name | Type    |
+-------------+---------+
| employee_id | int     |
| name        | varchar |
| salary      | int     |
+-------------+---------+
employee_id is the primary key for this table.
Each row of this table indicates the employee ID, employee name, and salary.
```

Write an SQL query to calculate the bonus of each employee. The bonus of an employee is `100%` of their salary if the ID of the employee is an odd number and the employee name does not start with the character `'M'`. The bonus of an employee is `0` otherwise.

Return the result table ordered by `employee_id`.

The query result format is in the following example:

```Employees table:
+-------------+---------+--------+
| employee_id | name    | salary |
+-------------+---------+--------+
| 2           | Meir    | 3000   |
| 3           | Michael | 3800   |
| 7           | Addilyn | 7400   |
| 8           | Juan    | 6100   |
| 9           | Kannon  | 7700   |
+-------------+---------+--------+

Result table:
+-------------+-------+
| employee_id | bonus |
+-------------+-------+
| 2           | 0     |
| 3           | 0     |
| 7           | 7400  |
| 8           | 0     |
| 9           | 7700  |
+-------------+-------+

The employees with IDs 2 and 8 get 0 bonus because they have an even employee_id.
The employee with ID 3 gets 0 bonus because their name starts with 'M'.
The rest of the employees get a 100% bonus.```

## Explanation

using if() and substring() functions.

## SQL Solution

``````# Write your MySQL query statement below
SELECT employee_id, IF(employee_id % 2 != 0 and SUBSTRING(name, 1, 1) != 'M', salary, 0) AS bonus from Employees``````
