1. List the item ID, description, and on-hand value (units on hand * unit price) of each item in category CAT. (On-hand value is technically units on hand * cost, but there is no COST column in the ITEM table). Assign the name ON_HAND_VALUE to the computed column.

The query is calculating the total on-hand value of items by category. The query will need to use the SUM function to add the total on-hand value of items in each category.

2. List the order number for each order placed by customer number 125 on 2021-11-15. This is what the results supposed to look like, what's the SQL code to use to get this result?

3. List the item ID, description, and on-hand value for each item where on-hand value is at least $1,500. Assign the name ON_HAND_VALUE to the computed column. This is what the results are supposed to look like. What's the SQL code to use to get this result?

4. List the item ID, description, and on-hand value of each item whose number of units on hand is more than the average number of units on hand for all items.

Use a subquery.

The output table should have the following column headers: ITEM_ID, DESCRIPTION, and ON_HAND_VALUE.

Make sure to create a sub-query to get the average on hand value of all items in the ITEM table in order to determine which items have more than the current average on hand.
