PROPERTY_GRAPHS view

The INFORMATION_SCHEMA.PROPERTY_GRAPHS view contains one row for each property graph in the dataset or region that you specify.

Required permissions

To query the INFORMATION_SCHEMA.PROPERTY_GRAPHS view, ask your administrator to grant you one of the following predefined IAM roles:

roles/bigquery.metadataViewer
roles/bigquery.dataViewer
roles/bigquery.admin

Schema

When you query the INFORMATION_SCHEMA.PROPERTY_GRAPHS view, the query results contain one row for each property graph in the resource scope that you specify.

The INFORMATION_SCHEMA.PROPERTY_GRAPHS view has the following schema:

Column name	Data type	Value
`property_graph_catalog`	`STRING`	The name of the project that contains the dataset where the property graph is defined.
`property_graph_schema`	`STRING`	The name of the dataset that contains the property graph.
`property_graph_name`	`STRING`	The name of the property graph.
`property_graph_metadata_json`	`STRING`	The JSON representation of the property graph definition. This representation contains information about the graph, such as its nodes, edges, labels, properties, creation timestamp, and modification timestamps.
`ddl`	`STRING`	A DDL statement that can be used to create the property graph.

Scope and syntax

Queries against this view must include a dataset or a region qualifier. For queries with a dataset qualifier, you must have permissions for the dataset. For queries with a region qualifier, you must have permissions for the project. For more information see Syntax. The following table explains the region and resource scopes for this view:

View name	Resource scope	Region scope
[PROJECT_ID.]`region-REGION`.INFORMATION_SCHEMA.PROPERTY_GRAPHS	Project level	`REGION`
`[PROJECT_ID.]DATASET_ID.INFORMATION_SCHEMA.PROPERTY_GRAPHS`	Dataset level	Dataset location

Replace the following:

Optional: PROJECT_ID: the ID of your Cloud de Confiance project. If not specified, the default project is used.
REGION: any dataset region name. For example, `region-us`.
DATASET_ID: the ID of your dataset. For more information, see Dataset qualifier.

Note: You must use a region qualifier to query INFORMATION_SCHEMA views. The location of the query execution must match the region of the INFORMATION_SCHEMA view.

Example

The following example retrieves the property_graph_name, property_graph_metadata_json, and ddl columns from the INFORMATION_SCHEMA.PROPERTY_GRAPHS view:

SELECT
  property_graph_name, property_graph_metadata_json, ddl
FROM
  `region-REGION`.INFORMATION_SCHEMA.PROPERTY_GRAPHS;

The result is similar to the following:

+---------------------+------------------------------------------------+------------------------------------------------------+
| property_graph_name | property_graph_metadata_json                   | ddl                                                  |
