Description

TCheckConstraint represents a record-level constraint on a dataset component.

cClient dataset components implement a Constraints property that uses check constraints to represent record-level constraints. These constraints can be derived from the server or the data dictionary, and can be customized in applications. Each TCheckConstraint object represents an individual constraint associated with a dataset.
