    MSSQL supports JSON-formatted data as of SQL Server 2016.

    The :class:`_mssql.JSON` datatype at the DDL level will represent the
    datatype as ``NVARCHAR(max)``, but provides for JSON-level comparison
    functions as well as Python coercion behavior.

    :class:`_mssql.JSON` is used automatically whenever the base
    :class:`_types.JSON` datatype is used against a SQL Server backend.

    .. seealso::

        :class:`_types.JSON` - main documentation for the generic
        cross-platform JSON datatype.

    The :class:`_mssql.JSON` type supports persistence of JSON values
    as well as the core index operations provided by :class:`_types.JSON`
    datatype, by adapting the operations to render the ``JSON_VALUE``
    or ``JSON_QUERY`` functions at the database level.

    The SQL Server :class:`_mssql.JSON` type necessarily makes use of the
    ``JSON_QUERY`` and ``JSON_VALUE`` functions when querying for elements
    of a JSON object.   These two functions have a major restriction in that
    they are **mutually exclusive** based on the type of object to be returned.
    The ``JSON_QUERY`` function **only** returns a JSON dictionary or list,
    but not an individual string, numeric, or boolean element; the
    ``JSON_VALUE`` function **only** returns an individual string, numeric,
    or boolean element.   **both functions either return NULL or raise
    an error if they are not used against the correct expected value**.

    To handle this awkward requirement, indexed access rules are as follows:

    1. When extracting a sub element from a JSON that is itself a JSON
       dictionary or list, the :meth:`_types.JSON.Comparator.as_json` accessor
       should be used::

            stmt = select(
                data_table.c.data["some key"].as_json()
            ).where(
                data_table.c.data["some key"].as_json() == {"sub": "structure"}
            )

    2. When extracting a sub element from a JSON that is a plain boolean,
       string, integer, or float, use the appropriate method among
       :meth:`_types.JSON.Comparator.as_boolean`,
       :meth:`_types.JSON.Comparator.as_string`,
       :meth:`_types.JSON.Comparator.as_integer`,
       :meth:`_types.JSON.Comparator.as_float`::

            stmt = select(
                data_table.c.data["some key"].as_string()
            ).where(
                data_table.c.data["some key"].as_string() == "some string"
            )
