6.1.1 Loading a SQL Property Graph from a Different Schema
You can specify the schema name when using the
readGraphByName API for loading a SQL property graph.
If you only provide the graph name when calling the
readGraphByName API, it is assumed that the graph is owned by current
user. But if you want to load a graph owned by another user, then you must provide the
schema name as well. Also, ensure that you have SELECT permission on the
SQL graph and all its underlying data tables.
The following example loads a SQL property graph
from the GRAPHUSER schema:
opg4j> var graph = session.readGraphByName("GRAPHUSER", "STUDENT_NETWORK", GraphSource.PG_SQL)
graph ==> PgxGraph[name=STUDENT_NETWORK,N=4,E=4,created=1680769031393]
PgxGraph graph = session.readGraphByName("GRAPHUSER", "STUDENT_NETWORK", GraphSource.PG_SQL);>>> graph = session.read_graph_by_name("STUDENT_NETWORK", "pg_sql", "GRAPHUSER")
>>> graph
PgxGraph(name: STUDENT_NETWORK_2, v: 4, e: 4, directed: True, memory(Mb): 0)
