NoCheck

Specifies whether Caché should check this foreign key constraint.

Usage

To prevent Caché from checking the constraint defined by this foreign key, use the following syntax:

ForeignKey keyname(key_props) References pkg.class(ref_index) [ NoCheck ];

Otherwise, omit this keyword or place the word Not immediately before the keyword.

Details

The NoCheck keyword suppresses the checking of the foreign key constraint (in other words, it specifies that the foreign key constraint never be checked).

Default

If you omit this keyword, Caché does check the foreign key constraint.
