Explanation:

Given

Tables: customer, sale, product

Required

Answer question 1 to 5

(1) All data in the given tables

To do this, we make use of the select clause to retrieve data from each of the table and * to select all data.

So, we have:

select * from customer --> This lists all data from customer table

select * from sale --> This lists all data from sale table

select * from product --> This lists all data from product table

(2) Selected details from customer table

In (1), we have:

select * from customer --> This lists all data from customer table

To retrieve selected details, we replace * with the field names.

So, we have:

select name, sex from customer

(3) Male customers

In (1), we have:

select * from customer --> This lists all data from customer table

To retrieve male customers, we introduce the where clause

So, we have:

select * from customer where sex = 'male'

(4) Name and age of male customers

In (3), we have:

select * from customer where sex = 'male'

To retrieve the name and age, we replace * with name and age. So, we have:

select name, age from customer where sex = 'male'

(5) Name, price and color of products

In (1), we have:

select * from product --> This lists all data from product table

To retrieve selected details, we replace * with the field names.

So, we have:

select name, price, color from product
