Seema,
Deletions use lots of rollback space and generate lots of redo. And if there are indexes and constraints its going to prolong the transaction. Depend on the number of records being deleted and availability of space. It is better to recreate the table without the records that are to be deleted. Then drop the original table, rename old table to the new 1, and recreating the indexes, triggers and constraints that were present b4. ** Just be careful with this approach though cause u need to know what u really doing. Regards Suhen Hi I want to delete milliuns of row from one table.that table have 2 constraints and some indexes.What to do for fast deletion.When ever I run deletion it takes time too.
