Result class abstract final Query

A single row in a ResultSet.

The name of a column is determined by the first applicable rule of the following rules:

  1. The alias name of an aliased column.
  2. The last component of a property expression. Functions for example, are not property expressions.
  3. A generated key of the format $1, $2, $3, ... The number after $ corresponds to the position of the column among the rest of the unnamed columns and starts at 1.
