LNNVL

LNNVL evaluates a condition when one or both operands of the condition may be null. LNNVL can be used anywhere a scalar expression can appear, even in contexts where the IS [NOT] NULL, AND, or OR conditions are not valid but would otherwise be required to account for potential nulls.

NOTE: This function returns 1 (true) if the condition is false or unknown, and 0 (false) if the condition is true.
