INFORMATION.SCHEMA.REFERENTIALCONSTRAINTS
persistent class INFORMATION.SCHEMA.REFERENTIALCONSTRAINTS extends %Library.Persistent [ Final ]
SQL Table Name: INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS
Returns one row for each FOREIGN KEY table constraint in the current namespace for tables that can be accessed by the current user in the current namespace. The REFERENTIAL_CONSTRAINTS table has one row for each row in the TABLE_CONSTRAINTS table that has a CONSTRAINT_TYPE value of "FOREIGN KEY".Property Inventory
