Constructeur sqlalchemy.Index.__init__

Signature de la constructeur __init__

def __init__(self, name: 'Optional[str]', *expressions: '_DDLColumnArgument', unique: 'bool' = False, quote: 'Optional[bool]' = None, info: 'Optional[_InfoType]' = None, _table: 'Optional[Table]' = None, _column_flag: 'bool' = False, **dialect_kw: 'Any') -> 'None' 

Description

help(Index.__init__)

Construct an index object.

:param name:
  The name of the index

:param \*expressions:
  Column expressions to include in the index.   The expressions
  are normally instances of :class:`_schema.Column`, but may also
  be arbitrary SQL expressions which ultimately refer to a
  :class:`_schema.Column`.

:param unique=False:
    Keyword only argument; if True, create a unique index.

:param quote=None:
    Keyword only argument; whether to apply quoting to the name of
    the index.  Works in the same manner as that of
    :paramref:`_schema.Column.quote`.

:param info=None: Optional data dictionary which will be populated
    into the :attr:`.SchemaItem.info` attribute of this object.

:param \**dialect_kw: Additional keyword arguments not mentioned above
    are dialect specific, and passed in the form
    ``<dialectname>_<argname>``. See the documentation regarding an
    individual dialect at :ref:`dialect_toplevel` for detail on
    documented arguments.
