Database key identifiers are in Record Selection Expressions.

  If a database exception condition occurs during the execution of a
  FETCH or FIND statement, the Database Control System (DBCS) places a
  database exception condition code in the special register
  DB-CONDITION.  This code identifies the condition.  The DBCS also
  places the record name of database-record in the special register
  DB-CURRENT-RECORD-NAME and its UID in DB-CURRENT-RECORD-ID.
