Clarifies a conditional expression. FALSE is equivalent to the integer 0.
Example
The following example uses FALSE in a DECODE expression to verify that values are between 25 and 30. This is useful if you want to perform multiple searches based on a single search value:
DECODE (FALSE, Var1 >= 25, 'Var1 not in desired range.', Var1 <= 30, 'Var1 not in desired range.', 'Var1 in desired range.')
