LNNVL

The LNNVL function provides a concise way to evaluate 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.

Return Values

TRUE if the condition is false or unknown and FALSE if the condition is true.

Syntax

LNNVL(condition)

Parameters

condition

An expression constructed using any scalar values. Note that you cannot specify an expression that contains AND, OR, or BETWEEN.
