Whenever we load data into oracle table from staging table using exchange partition...then I read somewhere that data actually doesn't move in this and this command only reset the pointer in the data dictionary...so if data doesn't move then how data is loaded into the main table ? I mean wat is the point of pointer update in data dictionary?
