How do I get information about an index and table owner in Oracle?

The following may help give you want you need:

SELECT
    index_owner, index_name, table_name, column_name, column_position
FROM DBA_IND_COLUMNS
ORDER BY
    index_owner, 
    table_name,
    index_name,
    column_position
    ;

For my use case, I wanted the column_names and order that they are in the indices (so that I could recreate them in a different database engine after migrating to AWS). The following was what I used, in case it is of use to anyone else:

SELECT
    index_name, table_name, column_name, column_position
FROM DBA_IND_COLUMNS
WHERE
    INDEX_OWNER = 'FOO'
    AND TABLE_NAME NOT LIKE '%$%'
ORDER BY
    table_name,
    index_name,
    column_position
    ;

 select index_name, column_name
 from user_ind_columns
 where table_name = 'NAME';

OR use this:

select TABLE_NAME, OWNER 
from SYS.ALL_TABLES 
order by OWNER, TABLE_NAME 

And for Indexes:

select INDEX_NAME, TABLE_NAME, TABLE_OWNER 
from SYS.ALL_INDEXES 
order by TABLE_OWNER, TABLE_NAME, INDEX_NAME

According to the docs, you can just do:

select INDEX_NAME, TABLE_OWNER, TABLE_NAME, UNIQUENESS from USER_INDEXES

or

select INDEX_NAME, TABLE_OWNER, TABLE_NAME, UNIQUENESS from ALL_INDEXES

if you want all indexes...

The following helped me as I didn't have DBA access and also wanted the column names.

See: https://dataedo.com/kb/query/oracle/list-table-indexes

select ind.table_owner || '.' || ind.table_name as "TABLE",
       ind.index_name,
       LISTAGG(ind_col.column_name, ',')
            WITHIN GROUP(order by ind_col.column_position) as columns,
       ind.index_type,
       ind.uniqueness
from sys.all_indexes ind
join sys.all_ind_columns ind_col
           on ind.owner = ind_col.index_owner
           and ind.index_name = ind_col.index_name
where ind.table_owner not in ('ANONYMOUS','CTXSYS','DBSNMP','EXFSYS',
       'MDSYS', 'MGMT_VIEW','OLAPSYS','OWBSYS','ORDPLUGINS', 'ORDSYS',
       'SI_INFORMTN_SCHEMA','SYS','SYSMAN','SYSTEM', 'TSMSYS','WK_TEST',
       'WKPROXY','WMSYS','XDB','APEX_040000','APEX_040200',
       'DIP', 'FLOWS_30000','FLOWS_FILES','MDDATA', 'ORACLE_OCM', 'XS$NULL',
       'SPATIAL_CSW_ADMIN_USR', 'SPATIAL_WFS_ADMIN_USR', 'PUBLIC',
       'LBACSYS', 'OUTLN', 'WKSYS', 'APEX_PUBLIC_USER')
    -- AND ind.table_name='TableNameGoesHereIfYouWantASpecificTable'
group by ind.table_owner,
         ind.table_name,
         ind.index_name,
         ind.index_type,
         ind.uniqueness 
order by ind.table_owner,
         ind.table_name;
