Write an SQL statement that will perform a daily sum aggregation on the field cost. It must only use costs that are associated with the follow items: Z001, Z002. The cost must also only come from division 1. Below is the example table that you will be retrieving data from:Costs
* Receipt
* Date
* Item
* Reason
* Division
* Cost
Much like your two other posts. This is obviously homework. What have you tried?
