UNION ALL INSTEAD OF UNION:

Also known asset operators, because they work as result sets. Both of these are used for combining results and are similar keywords. But they work a little differently. Union All shows all records in result sets, where Union shows all records except the duplicate ones. In short, Union eliminates duplicates where the union does not. In Oracle, they both are used when removing duplicate rows from the result set after combining, for this Union can be used where if you just want to combine the values and don’t care about duplicates then Union All can be used!
