Projection: add/remove columns
This query only returns one column. This one column contains the colors of Pokémon (bindings for variable ?color
).
The ?pokemon
variable is used in the graph pattern, but its bindings are not returned in the projection. Variables like ?pokemon
that are internal to the pattern component and are not exposed in the projection are called hidden variables.
Result sets must contain of at least one column. The same column may be included more than once.
