You need to change the value of the Email column for an existing customer row in the Customers table. Which type of Transact-SQL statement should you use to perform this data modification?
DELETE
ALTER
UPDATE
INSERT
An UPDATE statement changes the values of one or more columns in rows that already exist, so it is the correct choice for modifying the Email field of an existing customer. INSERT adds brand-new rows, DELETE removes rows, and ALTER changes the structure of the table rather than the data it stores.
