GOAL:

What is the order of records retrieved using a constant value as BY clause?

GOAL:

What sorting is used when the BY clause does not mention a field name?

FACT(s) (Environment):

Progress 9.x
OpenEdge 10.x

FIX:

The BY expression is evaluated when sorting the results of the query. If a constant value is used, then the same value is used to compare each record against another, as if using a field with the same value for all records. In this case the sort order is meaningless.
When the BY clause does not provide a meaningful sorting order, the resulting order of records is unspecified.
