Class Variable kind Undocumented

Inherited from TruncBase:

Method	`__init__`	Undocumented
Method	`as_sql`	Responsible for returning a (sql, [params]) tuple to be included in the current query.
Method	`convert_value`	Expressions provide their own converters because users have the option of manually specifying the output_field which may be a different type from the one the database returns.
Method	`resolve_expression`	Provide the chance to do any preprocessing or validation before being added to the query.
Instance Variable	`is_dst`	Undocumented
Instance Variable	`tzinfo`	Undocumented

Inherited from TimezoneMixin (via TruncBase):

Method get_tzname Undocumented

Inherited from Transform (via TruncBase):

Class Method	`get_lookups`	Undocumented
Class Method	`register_lookup`	Undocumented
Static Method	`merge_dicts`	Merge dicts in reverse to preference the order of the original list. e.g., merge_dicts([a, b]) will preference the keys in 'a' over those in 'b'.
Class Method	`_clear_cached_lookups`	Undocumented
Class Method	`_get_lookup`	Undocumented
Class Method	`_unregister_lookup`	Remove given lookup from cls lookups. For use in tests only as it's not thread-safe.
Method	`get_lookup`	Undocumented
Method	`get_transform`	Undocumented

Inherited from Func (via TruncBase, Transform):

Method	`__repr__`	Undocumented
Method	`_get_repr_options`	Return a dict of extra __init__() options to include in the repr.
Method	`copy`	Undocumented
Method	`get_source_expressions`	Undocumented
Method	`set_source_expressions`	Undocumented
Class Variable	`arg_joiner`	Undocumented
Class Variable	`function`	Undocumented
Class Variable	`template`	Undocumented
Instance Variable	`extra`	Undocumented
Instance Variable	`source_expressions`	Undocumented

Method as_sqlite Undocumented

Inherited from Expression (via TruncBase, Transform, Func):

Static Method	`_convert_value_noop`	Undocumented
Method	`__getstate__`	Undocumented
Method	`_parse_expressions`	Undocumented
Method	`_resolve_output_field`	Attempt to infer the output type of the expression. If the output fields of all source fields match then, simply infer the same type here. This isn't always correct, but it makes sense most of the time.
Method	`asc`	Undocumented
Method	`desc`	Undocumented
Method	`flatten`	Recursively yield this expression and all subexpressions, in depth-first order.
Method	`get_db_converters`	Undocumented

Method	`get_lookup`	Undocumented
Method	`get_source_fields`	Return the underlying field types used by this aggregate.
Method	`get_transform`	Undocumented
Method	`relabeled_clone`	Undocumented
Method	`reverse_ordering`	Undocumented
Method	`select_format`	Custom format for select clauses. For example, EXISTS expressions need to be wrapped in CASE WHEN on Oracle.
Class Variable	`_output_field_resolved_to_none`	Undocumented
Class Variable	`filterable`	Undocumented
Class Variable	`is_summary`	Undocumented
Class Variable	`window_compatible`	Undocumented
Property	`_output_field_or_none`	Return the output field of this expression, or None if _resolve_output_field() didn't return an output type.
Property	`conditional`	Undocumented
Property	`contains_aggregate`	Undocumented
Property	`contains_column_references`	Undocumented
Property	`contains_over_clause`	Undocumented
Property	`field`	Undocumented
Property	`output_field`	Return the output type of this expressions.
