Alter a nonunique index to a unique index

Question

I have a few non-unique constraints that I want to alter into unique constraints ( business rules have changed since the data model was made ). Is there any way to do it wi

Answer 1

In my case, just do drop and re-create the index:

DROP INDEX index_name;
CREATE UNIQUE INDEX index_name ON table_name (col01,col02) TABLESPACE indx;
