You are in the Marketing Department and are reviewing sales of coffee and espresso products. You are developing a new marketing campaign and need to know where the customers who purchase these products live. Develop a query to include these attributes in this order: the product name, the sales ship-to country, and the number of cities that each product has been shipped to. Use the AS keyword to temporarily rename the ship-to country attribute as "Country," the product name as "Product," and name the aggregate column as “Number of Cities." You want to include only coffee and espresso products. Add restrictions to the query output in this order: product names that include the pattern "coffee" and product names that end with the pattern "espresso." Sort the query

**Title: Understanding SQL Queries for Marketing Analysis**
**Introduction**
In the Marketing Department, analyzing sales data for coffee and espresso products is essential for developing effective campaigns. This guide will demonstrate how to structure an SQL query to gather insights on where customers are located and how many cities the products reach.
**Objective**
Create a query to retrieve:
- Product name
- Sales ship-to country
- Number of unique cities shipped to
The query should focus exclusively on products containing "coffee" or ending with "espresso" in their names. Additionally, the results should be sorted first by product name, then by the number of cities.
**SQL Statement Explanation**
To achieve this, we use SQL with specific clauses and statements, as follows:
```sql
SELECT Product.ProdName AS "Product",
Sale.ShipToCountry AS "Country",
COUNT(Sale.ShipToCity) AS "Number of Cities"
FROM (Sale
JOIN SaleProduct ON Sale.SaleID = SaleProduct.SaleID)
JOIN Product ON SaleProduct.ProdID = Product.ProdID
WHERE “Product” LIKE "%coffee%"
AND “Product” LIKE "%espresso"
GROUP BY "Product", "Country"
ORDER BY "Product", "Number of Cities";
```
**Explanation**
- **SELECT Statement**: Chooses the product names, the country to which products are shipped, and counts the number of different cities.
- **JOIN Clauses**:
- `Sale` and `SaleProduct` are joined using `SaleID` to connect sales with specific products.
- `Product` is joined using `ProdID` to link product details.
- **COUNT Function**: Calculates the number of unique cities where each product is shipped.
- **AS Clause**: Renames attributes for clearer output:
- `Product.ProdName` as "Product"
- `Sale.ShipToCountry` as "Country"
- Count of `ShipToCity` as "Number of Cities"
- **WHERE Clause**: Filters to include only products with "coffee" and those ending with "espresso" in their names.
- **GROUP BY**: Groups results by product and country.
- **ORDER BY**: Sorts the output first by product name, then by the number of cities.

**Outcome**
This query will generate a report titled "Coffee Products," providing insight into the distribution and reach
