Placeholder for the value within a :class:`.BindParameter`

to :meth:`.Connection.execute`.
This symbol is typically used when a :func:`.expression.insert`
or :func:`.expression.update` statement is compiled without parameter
values present.

possibly a RETURNING clause for it.
If the column has a Python-side default, we will create a bound
parameter for it and "pre-execute" the Python function. If
the column has a SQL expression default, or is a sequence,
we will add it directly into the INSERT statement and add a
RETURNING element to get the new value. If the column has a
server side default or is marked as the "autoincrement" column,
we will add a RETRUNING element to get at the value.
If all the above tests fail, that indicates a primary key column with no
noted default generation capabilities that has no parameter passed;
raise an exception.
