DRAG DROP
You have a database that contains the following tables:
A delivery person enters an incorrect value for the CustomerID column in the Invoices table and enters the
following text in the ConfirmedReceivedBy column: “Package signed for by the owner Tim.”
You need to find the records in the Invoices table that contain the word Tim in the CustomerName field.
How should you complete the Transact-SQL statement? To answer, drag the appropriate Transact-SQL

all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

this query returns all records where the name is tim, not the records of the Invoices table where the name is tim -> ” You need to find the records in the Invoices table that contain the word Tim in the CustomerName field”

I am able now to understand the question and the options because i have found this question in another place and it is “You need to find the records in the Invoices table that contain the word Tim in the CustomerName field along with the incorrectly entered row from the Sales.Invoice table.”
