Can't get database update applied after code update

Problem/Motivation

Did 'drush up' and drush dutifully updated draggableviews from 7.x-1.x-dev to 7.x-2.0. However the database update failed - see message below:

Update #7001
Failed: PDOException: SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes: ALTER TABLE {draggableviews_structure} CHANGE `view_name` `view_name` VARCHAR(128) NOT NULL DEFAULT '' COMMENT 'Makes the order unique for each view.'; Array ( ) in db_change_field() (line 2988 of /home/kayak/public_html/includes/database/database.inc).

Proposed resolution
