The QUERY_NAME field attribute clause provides VAX DATATRIEVE with an
  alternate  reference  name for a field.  VAX DATATRIEVE allows you to
  refer to a field either by its field name or  by  a  specified  query
  name.

1  –  Parameter

  dtrqn_quoted_string

       The VAX DATATRIEVE query name.

2  –  Syntax Rule

  The quoted string must be a valid VAX  DATATRIEVE  query  name.   The
  CDDL compiler does not check the quoted string for correct syntax.

3  –  Usage Notes

   o  Only  VAX  DATATRIEVE  supports  the  QUERY_NAME  clause.   Other
      processors ignore it.

   o  You can specify a query  name  for  a  field  only  if  you  have
      specified a field name for it in the field description statement.
      You can not specify a query name for unnamed fields.

   o  QUERY_NAME  is  different  from  NAME  because   VAX   DATATRIEVE
      recognizes both the query name and the original field name.  With
      NAME, the facility-specific name is the only name  recognized  by
      the specified language or language processor.

   o  Choose a query name that is shorter and easier to  remember  than
      the  actual field name.  You can then choose a field name that is
      descriptive of the field's contents and purpose.

   o  You can use 8-bit characters in CDDL quoted strings.

4  –  Example

  In the following example, the QUERY_NAME clause specifies  TP  as  an
  alternate DATATRIEVE name for the field TOTAL_PRICE.

  TOTAL_PRICE            DATATYPE IS VIRTUAL FIELD
                         COMPUTED BY DTR AS
                            "UNIT_PRICE * QUANTITY"
                         QUERY_NAME FOR DTR IS "TP".
