Indexed Fields

When you're querying ActivityFieldHistory with SOQL, you must specify indexed fields in the WHERE clause filter starting from the first field defined in the index. If you specify a partial list of indexed fields, don't leave any gaps between indexed fields after the first field. Here are the indexed fields for ActivityFieldHistory, listed from first to last in the index order.

1. ActivityId

2. ChangedDate

3. ChangedById

4. FieldName

5. ActivityFieldChange

For example, this SOQL query succeeds because the first three indexed fields are in the WHERE clause.

SELECT ActivityId, OldValueText, NewValueText, FieldName, ChangedDate
FROM ActivityFieldHistory
WHERE ActivityId = 'SomeId' AND ChangedDate >= :startDate AND ChangedDate <= :endDate
ORDER BY ChangedDate

If you remove the ActivityId field from the WHERE clause, the query fails.

SELECT ActivityId, OldValueText, NewValueText, FieldName, ChangedDate
FROM ActivityFieldHistory
WHERE ChangedDate >= :startDate AND ChangedDate <= :endDate
ORDER BY ChangedDate
