When working with databases, one of the most important skills is knowing how to view and arrange data to gain useful information. MySQL provides several ways to query databases in order to accomplish this. In this lab, we will run several queries in order to produce specific output.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- List All of the Rows in the `orders` and `products` Tables (run a single query for each)
Login to the MySQL server and change to the prod database:
[cloud_user@host]$ mysql -u root -p mysql> USE prod;
Run the following query to list the rows in the orders table:
mysql> SELECT * FROM orders;
Run the following query to list the rows in the products table:
mysql> SELECT * FROM products;
- Run a Query on the `orders` Table to Order the Rows by the `purchaseDate` Column in Ascending Order
Run the following query on the orders table:
mysql> SELECT * FROM orders ORDER BY purchaseDate;
- Run a Query on the Orders Table That Shows All the Names Beginning with the Letter “m”
Run the following query to show all the orders where the
name
begins with “m”:mysql> SELECT * FROM orders WHERE name LIKE 'm%';
- Run a Query on the `orders` Table That Shows All Purchases in 2018 Where the `productID` Is Less Than 4
Run the following query to show all purchases from 2018 where the
productID
is less than 4:mysql> SELECT * FROM orders WHERE purchaseDate LIKE '2018%' AND productID < 4;
- Run a Query on the `products` Table so That the Output Is in Alphabetical Order Based on the `type` Column
Run the following query on the products table so that the output is in alphabetical order:
mysql> SELECT * FROM products ORDER BY type;
- Run a Query on the `products` Table Where the Cost Is More Than or Equal to 1000
Run the following query to show where the cost is greater or equal to 1000:
mysql> SELECT * FROM products WHERE cost >= 1000;
- Run a Query on the `products` Table That Shows Output Where the Cost Is Greater Than 2000 or Less Than 500
Run the following query to show the items where cost is greater than 2000 or less than 500:
mysql> SELECT * FROM products WHERE cost > 2000 OR cost < 500;
- Show `orders.name`, `products.type`, and `products.cost` By Performing an Inner Join between `orders` and `products` Using `orders.productID` and `products.id`
Run the following command to perform an INNER JOIN on the orders and products table:
mysql> SELECT orders.name, products.type, products.cost FROM orders INNER JOIN products WHERE orders.productID = products.id;
