How To Drop an Index in Oracle?
✍: FYIcenter.com
If you don't need an existing index any more, you should delete it with the DROP INDEX statement. Here is an example SQL script:
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. SELECT index_name, table_name, uniqueness FROM USER_INDEXES WHERE table_name = 'STUDENT'; INDEX_NAME TABLE_NAME UNIQUENES ----------------------- --------------------- --------- SYS_C004129 STUDENT UNIQUE SYS_C004130 STUDENT UNIQUE STUDENT_BIRTH_DATE STUDENT NONUNIQUE DROP INDEX STUDENT_BIRTH_DATE; Index dropped.
