A logical predicate tests an operand against one or more other operands to evaluate to a logical (Boolean TRUE, FALSE, or UNKNOWN) result.

The tested operand can be one of the following:

  • A column name
  • A literal
  • An arithmetic expression
  • A Period expression, including a derived period
  • The DEFAULT function
  • A built-in function such as CURRENT_DATE or USER that evaluates to a system variable
