Using the MySQL workbench 8.0 CE
Modifying Tables
Using the My Guitar Shop database , develop the following queries.
To test whether a table has been modified correctly as you do these exercises, you can write and run an appropriate SELECT statement.
- Write an INSERT statement that adds this row to the Categories table:
category_name: Brass
Code the INSERT statement so MySQL automatically generates the category_id column. Execute the query and take a screenshot of the query and the results.
- Write an UPDATE statement that modifies the row you just added to the Categories table. This statement should change the category_name column to “Woodwinds,” and it should use the category_id column to identify the row. Execute the query and take a screenshot of the query and the results.
- Write a DELETE statement that deletes the row you added to the Categories table in exercise 1. This statement should use the category_id column to identify the row. Execute the query and take a screenshot of the query and the results.
- Write an INSERT statement that adds this row to the Products table:
product_id: The next automatically generated ID
category_id: 4
product_code: dgx_640
category_name: Yamaha DGX 640 88-Key Digital Piano
description: Long description to come.
list_price: 799.99
discount_percent: 0
date_added: Today’s date/time.
Use a column list for this statement. Execute the query and take a screenshot of the query and the results.
