Write a SQL SELECT query that will return the vendorID, invoiceNumber, and invoiceTotal from the invoices table where the invoiceTotalis less than the averageinvoiceTotal for that vendorID.Order by vendorID and then invoiceTotal.
This is a correlated subquery and a very similar example is found in chapter six.These are like self-joins in that a table aliased in the main query is used in the subquery.Be sure to understand the solution as opposed simply to copying it!There will be one or more of these on test two. (My solution has 36 rows.)
