@rbiswasThank you for your answer. I think with the help of update statement we can update multiple columns of a record for a specific where clause. And we can use where clause for a set of matching values using IN to update column values in multiple records with the same value. But I have a situation where I need to update multiple columns of multiple records with a set of values. Something like a similar kind of Merge operation where I need to retrieve the values from another hive table and update the transaction table. As far as I know update feature will not allow sub queries. Is there any other way which I am missing for this scenario?
