initial v1 52 52 }}} 53 53 54 I guess we could also use an hybrid approach where `SQLAggregateCompiler` only sets `supports_empty_result_set = False` if any of `outer_query.annotation_select.items()` is not a literal value prior to proceeding with the compilation/`as_sql` phase. That would keep the optimization for most cases but fallback to the database when it cannot be computed on the Python side.54 I guess we could also use an hybrid approach where `SQLAggregateCompiler` only sets `supports_empty_result_set = False` if any of `outer_query.annotation_select.items()` pass through `.get_empty_result()` is not a literal value prior to proceeding with the compilation/`as_sql` phase.
