Description

help(Executable.options)

Apply options to this statement.

In the general sense, options are any kind of Python object
that can be interpreted by the SQL compiler for the statement.
These options can be consumed by specific dialects or specific kinds
of compilers.

The most commonly known kind of option are the ORM level options
that apply "eager load" and other loading behaviors to an ORM
query.   However, options can theoretically be used for many other
purposes.

For background on specific kinds of options for specific kinds of
statements, refer to the documentation for those option objects.
