    • Method Detail

      • asField

        @NotNull
        <T> @NotNull Field<T> asField()
        The underlying field representation of this object.

        This method is useful for things like SELECT y.*, (SELECT a FROM x) FROM y

        Returns:
        This result provider as a Field<?> object
      • asField

        @NotNull
        <T> @NotNull Field<T> asField​(String alias)
        The underlying field representation of this object.

        This method is useful for things like SELECT y.*, (SELECT a FROM x) [alias] FROM y

        Note that the case-sensitivity of the returned field depends on Settings.getRenderQuotedNames(). By default, field aliases are quoted, and thus case-sensitive in many SQL dialects!

        Returns:
        This result provider as a Field<?> object

        - 3.14.0 - [#10156] - These methods will be removed without replacement from a future jOOQ. They offer convenience that is unidiomatic for jOOQ's DSL, without offering functionality that would not be possible otherwise - yet they add complexity in jOOQ's internals.

        This works like asField(String), except that field aliases are provided by a function. This is useful, for instance, to prefix all columns with a common prefix (on Table.as(String, Function)):

         MY_TABLE.as("t1", f -> "prefix_" + f.getName());
         

        And then to use the same function also for individual fields:

         MY_TABLE.MY_COLUMN.as(f -> "prefix_" + f.getName());
