Incase someone have doubts regarding joins she answered, her answers are right. All will have 6 records as output.

@apoorvgupta1993 3 ай бұрын

Ideally it should be 6 records as you will get a matching record every single time😬

@@apoorvgupta1993 thanks Sir , so duplicate combinations also included

Yes, in sql we can definitely get duplicate records.. that’s why we have the DISTINCT keyword to get only the distinct records if we want
