Progress OpenEdge 11.6 contains a new SQL feature called Autonomous Schema Update (ASU). This feature helps
overcome the SQL width problem that is encountered when database column values are larger than the column’s
size as defined in SQL. It solves this problem by automatically updating the SQL column width in schema wherever
there is a data truncation event for the column. Autonomous Schema Update is based on truncation events
generated by Authorized Data Truncation (ADT). (For more information on Authorized Data Truncation, please
refer to this recently updated whitepaper.)
