You are trying to create a function based index. To do so you need the query rewrite privilege
The index will still fail with a divide by 0 error (don't know why you are dividing by zero)

AS USER
create index wrong_logic on john(income/0) *
ERROR at line 1:
ORA-01031: insufficient privileges

AS SYS
SQL> connect internal
Connected.
SQL> grant query rewrite to user;

AS USER
SQL> create index wrong_logic on john(income/0); create index wrong_logic on john(income/0)

                                       *

ERROR at line 1:
ORA-01476: divisor is equal to zero

 1* create index wrong_logic on john(income/4) SQL> / Index created.

Hi guys,

This is my test:

SQL> desc emp

 Name                                      Null?    Type
 ----------------------------------------- -------- ------------------------
----
 EMPNO                                     NOT NULL CHAR(3)
 NAME                                               VARCHAR2(10)
 INCOME                                             NUMBER(5)

SQL> create index no_logic on emp(income);

Index created.

SQL> drop index no_logic;

Index dropped.

SQL> create index wrong_logic on emp(income/0); create index wrong_logic on emp(income/0)

                                       *

ERROR at line 1:
ORA-01031: insufficient privileges

I don't understand why Oracle throw such exception (reply). Do you have any idea what is Oracle doing when Oracle find out number / 0
