Description:
In MATCH clause you cannot use "WHERE boolean" Syntax. aka :
select * from GRAPH_TABLE (trajet MATCH ( a IS quai where
a.nom_station='Place des Fêtes' )-[t IS dessert where t.correspondance ]->(b
IS quai) columns (a.nom_station as station1, a.num_ligne as ligne1,
b.nom_station as station2, b.num_ligne as ligne2, T.correspondance as
correspondance));
ERROR: unrecognized node type: 63
You have to add " = true" (ugly) :
select * from GRAPH_TABLE (trajet MATCH ( a IS quai where
a.nom_station='Place des Fêtes' )-[t IS dessert where t.correspondance=true
]->(b IS quai) columns (a.nom_station as station1, a.num_ligne as ligne1,
b.nom_station as station2, b.num_ligne as ligne2, T.correspondance as
correspondance));
station1 | ligne1 | station2 | ligne2 | correspondance
-----------------+--------+-----------------+--------+----------------
Place des Fêtes | 7bis | Place des Fêtes | 11 | t
Place des Fêtes | 11 | Place des Fêtes | 7bis | t
