I'm just glad the question didn't ask us to use the MERGE statement to do the hokey pokey. That would have been a real brain-twister!

MERGE? Really? I was thinking CREATE would be the best way to create a new table. Oh wait, this is an update scenario. MERGE it is!

User3: CREATE would be for creating a new table, but in this case, MERGE is the way to go for updating Table1.

The MERGE operation seems like the obvious choice here to update the Type 2 SCD table. It can handle both insert and update scenarios seamlessly.

I'm not sure, but I think MERGE makes sense because it allows you to insert, update, or delete records based on a condition.
