hi guys, iam here to share one question in recent interview, the question is why need to check primary key, as giving primary key constraint it will not allow duplicates and null values as well, so what make us necessary to check primary key ? plz help me with explanation.....

[@WhizdomTrainings]

In a complex multi tier app .. thats imp. Atleast you need to check if duplicate records are not going in

[@vigneshb5180]

In some scenario there maybe combination of pk and not a single pk, so in that case it is important to check for duplicates it also that pk may be the fk for its parent table to check the referential integrity with its parent, so it is important to have 2 main scenarios using pk, one is duplicate check and other one is referential integrity check
