How To Recover a Dropped Index?

by **Micheal** Tue Jan 19, 2010 7:34 am

If you have the recycle bin feature turned on, dropped indexes are stored in the recycle bin. But it
seems to be command to restore a dropped index out of the recycle bin. FLASHBACK INDEX is
not a valid statement. See the following script:
ALTER SESSION SET recyclebin = on;
Statement processed.
CREATE TABLE student (id NUMBER(5) PRIMARY KEY,
first_name VARCHAR(80) NOT NULL,
last_name VARCHAR(80) NOT NULL,
birth_date DATE NOT NULL,
social_number VARCHAR(80) UNIQUE NOT NULL);
Table created.
CREATE INDEX student_birth_date ON student(birth_date);
Index created.
DROP INDEX STUDENT_BIRTH_DATE;
Index dropped.
SELECT object_name, original_name, type, droptime FROM recyclebin;
OBJECT_NAME ORIGINAL_NAME TYPE DROPTIME
------------------------------ ------------------ ----- ----------

FLASHBACK INDEX student_birth_date TO BEFORE DROP;
