You execute this SQL statement:

Which three statements are true? (Choose three.)

The statement will execute successfully and a new row will be inserted into the SALES table.

A product can have a different unit price at different times.

The statement will fail if a row already exists in the SALES table for product 23.

The statement will fail because a subquery may not be contained in a VALUES clause.

A customer can exist in many countries.

The SALES table has five foreign keys.

Correct Answer: A, B, F

The statement will execute successfully and a new row will be inserted into the SALES table, as there is nothing syntactically incorrect with the SQL statement. A product can have a different unit price at different times as it might be updated or changed in the PRODUCT table. The SALES table has five foreign keys, which can be inferred from the structure and relationships generally present in such tables.
