You can a list of indexes in your schema from the USER_INDEXES view, but it will not give you the columns used in each index in the USER_INDEXES view. If you want to see the columns used in an index, you can use the USER_IND_COLUMNS view. Here is an example script for you:
SELECT index_name, table_name, column_name FROM USER_IND_COLUMNS WHERE table_name = 'EMPLOYEES'; INDEX_NAME TABLE_NAME COLUMN_NAME -------------------- ---------------- ---------------- EMP_EMAIL_UK EMPLOYEES EMAIL EMP_EMP_ID_PK EMPLOYEES EMPLOYEE_ID EMP_DEPARTMENT_IX EMPLOYEES DEPARTMENT_ID EMP_JOB_IX EMPLOYEES JOB_ID EMP_MANAGER_IX EMPLOYEES MANAGER_ID EMP_NAME_IX EMPLOYEES LAST_NAME EMP_NAME_IX EMPLOYEES FIRST_NAME
