Synopsis
DROP INDEX
[schema
.]index_name
Removes an index (index_name) from the database.
Note
The index to be dropped must be in your schema, or you must have the
DROP ANY INDEX privilege to remove an object from another schema.
Example
The following example removes the index empno_ndx from scott’s
schema in the database. When an index is dropped, all of the space it
previously occupied is returned to the free space pool:
DROP INDEX scott.empno_ndx
