                                               KeyIs

A trigger firing when the value of key in row is equal to the value given.

Missing keys are always accepted. You can define an SQL type; value will then be interpreted as a literal for this type, and this literal's value will be compared against the key's value. This is only needed for grammars like fitsProductGrammar that actually yield typed values.
