Write SQL codes for these requirements based off of the five tables below. I have attached five pictures of the five tables there are with what each of them contain.

1.List unique item classes stored in my database.

2.List the warehouse number and the number of different parts stored in each

warehouse, only include those warehouse with more than 2 different parts.

3.List the warehouse number and the maximum number of units on hand for parts stored

in each of the warehouse. Rename the new column Max_UOH.

4.List the part number, total dollar amount for each part stored, and the warehouse

number for the part. Rename the calculated column TOTAL_AMOUNT.

TOTAL_AMOUNT=Units_ON_HAND*UNIT_PRICE

5.List the class and total number of units on hand for each class. Rank your results in

descending order on the total number of units on hand.

6.List stored information for all the orders placed between August 3rd and August 6th of

2013. (not including August 3rd 2013 and August 6th 2013).

7.List all the order date and the number of orders placed on each date. Rank your results

in descending order on the number of orders.
