Answer:
4
Step-by-step explanation:
From the given query, four columns are been called when we study the query closely.
Select VendorName, InvoiceNumber, InvoiceDate, InvoiceTotal From Vendors Inner Join Invoices On Vendors.VendorID = Invoices.VendorID Where InvoiceTotal >= 500 Order By VendorName Desc
The column are VendorName, InvoiceNumber, InvoiceDate, InvoiceTotal.
And the table name is Vendors.
With inner join on another table called Invoices
On Vendors.VendorID = Invoices.VendorID
Where InvoiceTotal >= 500
Order By VendorName in descending order
So, from the above the resultset will have four (4) columns.
