Excepting the above points, a virtual column, exists just like any other column of a normal table and the following points apply to it: Here we have defined a virtual column “total_sal” whose value would be dynamically calculated using the expression provided after the “generated always as” clause.
Please note that this declaration is different than using “default” clause for a normal column as you can’t refer column names with “default” clause.
Let's create a quick partitioned table example and see how moving a row works.You could split the default partition and add the new location name.How would you move records from the old partitioned into the new one?Why would a row move and who or what controls that movement? With newer releases of the Oracle RDBMS, where else does row movement come into play, and are there any gotcha's with respect to row movement operations? Does a row move to another table, or is row movement constrained to the row's container (i.e., a table)?
