Q5. Suppose you have a database table named orders that contains information about customer orders, including the customer name, product name, and order date. Write a MySQL query to create a view named monthly_orders that displays the total number of orders for each month and year.

The orders table has the following columns:

order_id (int)

customer_name (varchar)

product_name (varchar)

order_date (date)

Your view should have the following columns:

year (int)

month (int)

total_orders (int)

Your query should group the orders by month and year, and calculate the total number of orders for each group. The year and month columns should be extracted from the order_date column.

Hereâ€™s an example output of the monthly_orders view:

year | month | total_orders |
---|---|---|

2022 | 1 | 10 |

2022 | 2 | 12 |

2022 | 3 | 15 |

2022 | 4 | 8 |

2022 | 5 | 9 |
