NoCheck (Foreign Key Keyword)

Specifies whether InterSystems IRIS should check this foreign key constraint.


To prevent InterSystems IRIS 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.


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


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