ISSUE:       985
TITLE:       ORDER BY on a VIEW turns values in fields into NULL
DESCRIPTION:
NOTES:
[30.10.2019] NB: new datatype in FB 4.0 was introduces: numeric(38,0).
  It can lead to additional ident of values when we show them in form "SET LIST ON",
  so we have to ignore all internal spaces - see added 'substitution' section below.
JIRA:        CORE-623
