That's normal for a DESCending index, as Oracle creates a function-based index for this.
Check all|user|dba_ind_expressions for the column name in column_expression.

I create a table as follows:

create table a ( a number(1));

Then I create index as :

create index ia on a(a desc);

If i see the index columns as :

select index_name, table_name, column_name, column_position from all_ind_columns where table_name = 'A';

index_name	table_name	column_name		column_position
IA		A		SYS_NC00002$	1

What is the reason for the change in the column name of the index. How to avoid this?

TIA
