        There are at least four separate strategies used here, selected
        depending on the type of SQL construct used to start with.

        The most common case is that of the compiled SQL expression construct,
        which generated the column names present in the raw SQL string and
        which has the identical number of columns as were reported by
        cursor.description.  In this case, we assume a 1-1 positional mapping
        between the entries in cursor.description and the compiled object.
        This is also the most performant case as we disregard extracting /
        decoding the column names present in cursor.description since we
        already have the desired name we generated in the compiled SQL
        construct.

        The next common case is that of the completely raw string SQL,
        such as passed to connection.execute().  In this case we have no
        compiled construct to work with, so we extract and decode the
        names from cursor.description and index those as the primary
        result row target keys.

        The remaining fairly common case is that of the textual SQL
        that includes at least partial column information; this is when
        we use a :class:`_expression.TextualSelect` construct.
        This construct may have
        unordered or ordered column information.  In the ordered case, we
        merge the cursor.description and the compiled construct's information
        positionally, and warn if there are additional description names
        present, however we still decode the names in cursor.description
        as we don't have a guarantee that the names in the columns match
        on these.   In the unordered case, we match names in cursor.description
        to that of the compiled construct based on name matching.
        In both of these cases, the cursor.description names and the column
        expression objects and names are indexed as result row target keys.

        The final case is much less common, where we have a compiled
        non-textual SQL expression construct, but the number of columns
        in cursor.description doesn't match what's in the compiled
        construct.  We make the guess here that there might be textual
        column expressions in the compiled construct that themselves include
        a comma in them causing them to split.  We do the same name-matching
        as with textual non-ordered columns.

        The name-matched system of merging is the same as that used by
        SQLAlchemy for all cases up through te 0.9 series.   Positional
        matching for compiled SQL expressions was introduced in 1.0 as a
        major performance feature, and positional matching for textual
        :class:`_expression.TextualSelect` objects in 1.1.
        As name matching is no longer
        a common case, it was acceptable to factor it into smaller generator-
        oriented methods that are easier to understand, but incur slightly
        more performance overhead.

�Zd�ZRS(s�A cursor fetch strategy with row buffering behavior.

    This strategy buffers the contents of a selection of rows
    before ``fetchone()`` is called.  This is to allow the results of
    ``cursor.description`` to be available immediately, when
    interfacing with a DB-API that requires rows to be consumed before
    this information is available (currently psycopg2, when used with
    server-side cursors).

    The pre-fetching behavior fetches only one row initially, and then
    grows its buffer size by a fixed amount with each successive need
    for additional rows up the ``max_row_buffer`` size, which defaults
    to 1000::

        with psycopg2_engine.connect() as conn:

            result = conn.execution_options(
                stream_results=True, max_row_buffer=50
                ).execute(text("select * from table"))

    .. versionadded:: 1.4 ``max_row_buffer`` may now exceed 1000 rows.

        This releases all DBAPI cursor resources, but leaves the
        CursorResult "open" from a semantic perspective, meaning the
        fetchXXX() methods will continue to return empty results.

        This method is called automatically when:

        * all result rows are exhausted using the fetchXXX() methods.
        * cursor.description is None.

        This method is **not public**, but is documented in order to clarify
        the "autoclose" process used.

        :attr:`_engine.CursorResult.inserted_primary_key`
        as a row contained within a list; some dialects may support a
        multiple row form as well.

        .. note:: As indicated below, in current SQLAlchemy versions this
           accessor is only useful beyond what's already supplied by
           :attr:`_engine.CursorResult.inserted_primary_key` when using the
           :ref:`postgresql_psycopg2` dialect.   Future versions hope to
           generalize this feature to more dialects.

        This accessor is added to support dialects that offer the feature
        that is currently implemented by the :ref:`psycopg2_executemany_mode`
        feature, currently **only the psycopg2 dialect**, which provides
        for many rows to be INSERTed at once while still retaining the
        behavior of being able to return server-generated primary key values.

        * **When using the psycopg2 dialect, or other dialects that may support
          "fast executemany" style inserts in upcoming releases** : When
          invoking an INSERT statement while passing a list of rows as the
          second argument to :meth:`_engine.Connection.execute`, this accessor
          will then provide a list of rows, where each row contains the primary
          key value for each row that was INSERTed.

        * **When using all other dialects / backends that don't yet support
          this feature**: This accessor is only useful for **single row INSERT
          statements**, and returns the same information as that of the
          :attr:`_engine.CursorResult.inserted_primary_key` within a
          single-element list. When an INSERT statement is executed in
          conjunction with a list of rows to be INSERTed, the list will contain
          one row per row inserted in the statement, however it will contain
          ``None`` for any server-generated values.

        Future releases of SQLAlchemy will further generalize the
        "fast execution helper" feature of psycopg2 to suit other dialects,
        thus allowing this accessor to be of more general use.

           Notes regarding :attr:`_engine.CursorResult.rowcount`:


           * This attribute returns the number of rows *matched*,
             which is not necessarily the same as the number of rows
             that were actually *modified* - an UPDATE statement, for example,
             may have no net change on a given row if the SET values
             given are the same as those present in the row already.
             Such a row would be matched but not modified.
             On backends that feature both styles, such as MySQL,
             rowcount is configured by default to return the match
             count in all cases.

           * :attr:`_engine.CursorResult.rowcount`
             is *only* useful in conjunction
             with an UPDATE or DELETE statement.  Contrary to what the Python
             DBAPI says, it does *not* return the
             number of rows available from the results of a SELECT statement
             as DBAPIs cannot support this functionality when rows are
             unbuffered.

           * :attr:`_engine.CursorResult.rowcount`
             may not be fully implemented by
             all dialects.  In particular, most DBAPIs do not support an
             aggregate rowcount result from an executemany call.
             The :meth:`_engine.CursorResult.supports_sane_rowcount` and
             :meth:`_engine.CursorResult.supports_sane_multi_rowcount` methods
             will report from the dialect if each usage is known to be
             supported.

           * Statements that use RETURNING may not return a correct
             rowcount.

        This is a DBAPI specific method and is only functional

        consistent across backends.

        Usage of this method is normally unnecessary when
        using insert() expression constructs; the
        :attr:`~CursorResult.inserted_primary_key` attribute provides a

sHA Result that is representing state from a DBAPI cursor.

    .. versionchanged:: 1.4  The :class:`.CursorResult` and
       :class:`.LegacyCursorResult`
       classes replace the previous :class:`.ResultProxy` interface.
       These classes are based on the :class:`.Result` calling API
       which provides an updated usage model and calling facade for
       SQLAlchemy Core and SQLAlchemy ORM.

    Returns database rows via the :class:`.Row` class, which provides
    additional API features and behaviors on top of the raw data returned by
    the DBAPI.   Through the use of filters such as the :meth:`.Result.scalars`
    method, other kinds of objects may also be returned.

    Within the scope of the 1.x series of SQLAlchemy, Core SQL results in
    version 1.4 return an instance of :class:`._engine.LegacyCursorResult`
    which takes the place of the ``CursorResult`` class used for the 1.3 series
    and previously.  This object returns rows as :class:`.LegacyRow` objects,
    which maintains Python mapping (i.e. dictionary) like behaviors upon the
    object itself.  Going forward, the :attr:`.Row._mapping` attribute should
    be used for dictionary behaviors.

        :class:`_engine.CursorResult` and :class:`.Row` objects.

 cCs|jdt�dS(s�Close this :class:`_engine.CursorResult`.

        This closes out the underlying DBAPI cursor corresponding to the
        statement execution, if one is still present.  Note that the DBAPI
        cursor is automatically released when the :class:`_engine.CursorResult`
        exhausts all available rows.  :meth:`_engine.CursorResult.close` is
        generally an optional method except in the case when discarding a
        :class:`_engine.CursorResult` that still has additional rows pending
        for fetch.

        After this method is called, it is no longer valid to call upon
        the fetch methods, which will raise a :class:`.ResourceClosedError`
        on subsequent use.

        This method has the same behavior as that of

        the underlying :class:`.Connection` for the case of "connectionless"
        execution.

           be removed in version 2.0.   Version 2.0 will feature the
           :class:`_future.Result`
           object that will no longer affect the status
           of the originating connection in any case.

        After this method is called, it is no longer valid to call upon
