Final answer:

The statement 'No two records can have the same value in the primary key field' is True.

Step-by-step explanation:

The statement 'No two records can have the same value in the primary key field' is True. In database management, a primary key is a unique identifier for each record in a table. It ensures that no two records have the same value in the primary key field. Primary keys are essential for data integrity and to maintain the uniqueness of records within a table.

For example, let's consider a table of students with a primary key field called 'student_id'. Each student_id should have a unique value assigned to it. This ensures that each student in the table can be uniquely identified and no duplicate records exist.
