A developer asks it before adding an index that might already exist. A DBA asks it when a query scans a whole table and the team swears an index is in place. The answer is in the data dictionary, one row per indexed column.</p> <p><code>DBA_IND_COLUMNS</code> describes the columns of all the indexes on all tables and clusters in the database. The query below takes an index name and lists its columns in the order they sit in the index. Two further queries start from a table name instead, and one folds each index into a single line with a column list.</p>
