E.g.:: const = ExcludeConstraint( (Column("period"), "&&"), (Column("group"), "="), where=(Column("group") != "some group"), ops={"group": "my_operator_class"}, ) The constraint is normally embedded into the :class:`_schema.Table` construct directly, or added later using :meth:`.append_constraint`:: some_table = Table( "some_table", metadata, Column("id", Integer, primary_key=True), Column("period", TSRANGE()), Column("group", String), ) some_table.append_constraint( ExcludeConstraint( (some_table.c.period, "&&"), (some_table.c.group, "="), where=some_table.c.group != "some group", name="some_table_excl_const", ops={"group": "my_operator_class"}, ) ) The exclude constraint defined in this example requires the ``btree_gist`` extension, that can be created using the command ``CREATE EXTENSION btree_gist;``. :param \*elements: A sequence of two tuples of the form ``(column, operator)`` where "column" is either a :class:`_schema.Column` object, or a SQL expression element (e.g. ``func.int8range(table.from, table.to)``) or the name of a column as string, and "operator" is a string containing the operator to use (e.g. `"&&"` or `"="`). In order to specify a column name when a :class:`_schema.Column` object is not available, while ensuring that any necessary quoting rules take effect, an ad-hoc :class:`_schema.Column` or :func:`_expression.column` object should be used. The ``column`` may also be a string SQL expression when passed as :func:`_expression.literal_column` or :func:`_expression.text` :param name: Optional, the in-database name of this constraint. :param deferrable: Optional bool. If set, emit DEFERRABLE or NOT DEFERRABLE when issuing DDL for this constraint. :param initially: Optional string. If set, emit INITIALLY when issuing DDL for this constraint. :param using: Optional string. If set, emit USING when issuing DDL for this constraint. Defaults to 'gist'. :param where: Optional SQL expression construct or literal SQL string. If set, emit WHERE when issuing DDL for this constraint. :param ops: Optional dictionary. Used to define operator classes for the elements; works the same way as that of the :ref:`postgresql_ops ` parameter specified to the :class:`_schema.Index` construct. .. versionadded:: 1.3.21 .. seealso:: :ref:`postgresql_operator_classes` - general description of how PostgreSQL operator classes are specified.
