Can be omitted entirely; a :class:`_expression.Insert` construct will also dynamically render the VALUES clause at execution time based on the parameters passed to :meth:`_engine.Connection.execute`. :param inline: if True, no attempt will be made to retrieve the SQL-generated default values to be provided within the statement; in particular, this allows SQL expressions to be rendered 'inline' within the statement without the need to pre-execute them beforehand; for backends that support "returning", this turns off the "implicit returning" feature for the statement. If both :paramref:`_expression.insert.values` and compile-time bind parameters are present, the compile-time bind parameters override the information specified within :paramref:`_expression.insert.values` on a per-key basis. The keys within :paramref:`_expression.Insert.values` can be either :class:`~sqlalchemy.schema.Column` objects or their string identifiers. Each key may reference one of: * a literal data value (i.e. string, number, etc.); * a Column object; * a SELECT statement. If a ``SELECT`` statement is specified which references this ``INSERT`` statement's table, the statement will be correlated against the ``INSERT`` statement. .. seealso:: :ref:`tutorial_core_insert` - in the :ref:`unified_tutorial` r©r ©rúZ/var/www/html/api-tag/env/lib/python3.10/site-packages/sqlalchemy/sql/_dml_constructors.pyÚinserts;rr cCr)a%Construct an :class:`_expression.Update` object.
