Progress OpenEdge 11.5.1 contains a new SQL feature called Authorized Data Truncation.* 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. Authorized Data Truncation can prevent queries from failing when the large column values are read. By default, if the width of the column data being operated on in a query exceeds the defined width of the column, SQL returns an error, and as a result the query fails. If Authorized Data Truncation is enabled, SQL will instead truncate the large value down to the defined size. This truncation is acceptable as a temporary workaround to help applications succeed. Truncation changes data values significantly. Users will be able to see that the values were truncated, as Data Truncation optionally logs the truncation.
