重新登录后无法访问图形

Question

我在AgensGraph上创建了图形。

visitFieldElement(FieldElement element)

但是，重新登录后无法访问图形。

重新登录后如何访问图形

Answer 1

使用“ ALTER USER ... SET GRAPH_PATH TO ...”语句在登录时设置默认图形。

$ agens
agens (AgensGraph 2.1.0, based on PostgreSQL 10.4)
Type "help" for help.

agens=# create graph g;
CREATE GRAPH
agens=# alter user agens set graph_path to g;
ALTER ROLE
agens=# create (:v{id:1});
GRAPH WRITE (INSERT VERTEX 1, INSERT EDGE 0)
agens=# \quit

更改“ GRAPH_PATH”后，您可以访问图形。

$ agens
agens (AgensGraph 2.1.0, based on PostgreSQL 10.4)
Type "help" for help.

agens=# match (n) return n;
        n        
-----------------
 v[3.1]{"id": 1}
(1 row)
