SQL

How to run the HANA SQL function where an output table is required? Example function (from this tutorial): CREATE TYPE "TT_RESTAURANTS" AS TABLE ("node_id" INTEGER, "distance" INTEGER, "hops" BIGINT); CREATE OR REPLACE PROCEDURE "NEAREST_RESTAURANT"(IN startV INT, OUT res "TT_RESTAURANTS") LANGUAGE GRAPH READS SQL DATA AS BEGIN GRAPH g = Graph("SKIING"); VERTEX v_s = Vertex(:g, :startV); MULTISET<Vertex> rests = v IN Vertices(:g) WHERE :v."restaurant" == N'TRUE'; ALTER g ADD TEMPORARY VERTEX ATTRIBUTE (INT "distance" = 0); ALTER g ADD TEMPORARY VERTEX ATTRIBUTE (BIGINT "hops" = 0L); FOREACH rest in :rests { VERTEX v_rest = Vertex(:g, :rest."node_id"); WeightedPath<INT> p = Shortest_Path(:g, :v_s, :v_rest, (Edge conn) => INTEGER { return :conn."length"; } ); rest."hops" = Length(:p); rest."distance" = Weight(:p); } res = SELECT :v."node_id", :v."distance", :v."hops" FOREACH v IN :rests; END; ...
