index columns

[elaine3839]

Which data dictionary views should I query against to find out which columns are used in certain index? I tried to look it up from user_indexes, but didn't find this kind of info over there.

Thanks!

see user_ind_columns

Try user_ind_columns or dba_ind_columns or all_ind_columns. These can show you the index_name, table_name and column_names used for the indexes.
