deprecated persistent class %iKnow.Objects.VirtualCrcUnique extends %Library.Persistent

SQL Table Name: %iKnow_Objects.VirtualCrcUnique

This is a read-only object representation wrapping the internal iKnow data structures for unique CRCs in a Virtual Source.

This class can be used from ObjectScript or SQL to access a single or small number of entries, but the storage mappings are not meant to support elaborate or complex queries targeting this SQL table.

Please use the predefined queries in %iKnow.Queries.CrcAPI and other query classes to consult CRC data as the internal global structures are designed to optimize performance for these queries rather than general-purpose access.

Property Inventory


parameter READONLY = 1;
Inherited description: READONLY = 1 means that objects can be created, opened but not saved or deleted. Tables are projected to SQL as READONLY.
