Description

Disables the enforcement of constraints.

Call DisableConstraints to prevent, on a temporary basis, enforcement of constraints that have been assigned to the dataset or its fields. For example, when an application iterates through a client dataset, it may improve performance to disable constraints temporarily.

Note: Calling DisableConstraints increments a reference count. As long as this reference count is greater than zero, constraints are disabled for the dataset. To prevent accidental disabling of constraints, always group a call to DisableConstraints with a call to EnableConstraints.
