Mostly we use the join operator and use the distinct key word to fix the duplicate but using exists operator it is more reliable to use and next time we have to appear distinct records then we can use exists operator because it's show unique output which is exists in another table.

I wouldnt even think of Join even if I hadn't known about Exists. I'd just find out the ID from the Customer table and check if its IN the orders table. Would that be of the same complexity as Exists?

Hi @Shashank, Performance wise which is better. join or exists? consider I have millions of records.

If it is related to lookup then join will be a nightmare for this use case considering million rows
