DROP TABLE removes the specified table.
DROP TABLE table-Name
Triggers, constraints (primary, unique, check and references from the table being dropped) and indexes on the table are silently dropped. The existence of an open cursor that references table being dropped cause the DROP TABLE statement to generate an error, and the table is not dropped.
Dropping a table invalidates statements that depend on the table. (Invalidating a statement causes it to be recompiled upon the next execution. See Interaction with the dependency system.)
