4.2 Revalidating a SQL Property Graph
Using the ALTER PROPERTY GRAPH COMPILE
DDL statement, you
can revalidate an existing property graph object in the database.
A SQL property graph schema may become invalid due to the alteration of
the underlying database objects. For instance, adding or dropping a column from the
underlying database tables, used in the graph definition, can cause the graph to become
invalid. Any invalidation of the graph will also invalidate cursors depending on the
graph object. In such a case, you can recover your property graph from an invalid
state as shown in the following example. Also, refer to Granting System and Object Privileges for SQL Property Graphs to ensure you have the required privilege to perform the
ALTER PROPERTY GRAPH
operation.
