class documentation

class ResultColumnsEntry(NamedTuple): (source)

Tracks a column expression that is expected to be represented in the result rows for this statement. This normally refers to the columns clause of a SELECT statement but may also refer to a RETURNING clause, as well as for dialect-specific emulations.

Class Variable	`keyname`	string name that's expected in cursor.description
Class Variable	`name`	column name, may be labeled
Class Variable	`objects`	sequence of objects that should be able to locate this column in a RowMapping. This is typically string names and aliases as well as Column objects.
Class Variable	`type`	Datatype to be associated with this column. This is where the "result processing" logic directly links the compiled statement to the rows that come back from the cursor.
