A handle, sometimes known as an internal key, is a permanent representation of an object instance key in an external character string format. A handle uniquely identifies the instance, though in a format that differs from the normal presentation. Internally, the pzInsKey property holds the handle value for the object.
A handle identifies the class, certain key parts, and (for rules and some other classes) the creation date and time of a single instance. So, the pzInsKey property for a new rule has no value until the rule instance is saved.
When a database administrator creates a new table in the PegaRULES database, ensure that the table definition includes a database constraint that identifies the pzInsKey column as the primary key of the table.
