A primary key is a field or combination of fields that can uniquely identify each record in a table

Primary key

  • In a database table, a primary key is a field that uniquely identifies each row/record.
  • The value of a primary key must be distinct. NULL values cannot exist in a primary key column.
  • Only one primary key can exist in a table, and it can be made up of one or more fields. A composite key is what happens when numerous fields are combined as a primary key.
