    Regarding this

    ... default candidate key to be used to select particular rows of the table

    Can anyone expand on what is meant by 'default' here?

    When there are multiple candidate keys, the primary key is the one you turn to first. Hence the name primary key.

    Hmm - "the one you turn to first" - what do you mean, practically?
