Name
ST_Reverse — Retorna a geometria com a ordem dos vértices revertida.
Synopsis
geometry ST_Reverse(
geometry g1)
;
Descrição
Pode ser usado em qualquer geometria e reverte a ordem dos vértices.
Enhanced: 2.4.0 support for curves was introduced.
This function supports 3d and will not drop the z-index.
This function supports Polyhedral surfaces.
Exemplos
