class Predicate extends GeneralScalarExpression

The general representation of predicate expressions, which contains the upper-cased expression name and all the children expressions. You can also use these concrete subclasses for better type safety: And, Or, Not, AlwaysTrue, AlwaysFalse.

The currently supported predicate expressions:

  • Name: IS_NULL
  • SQL semantic: expr IS NULL
  • Since version: 3.3.0
  • Name: IS_NOT_NULL
  • SQL semantic: expr IS NOT NULL
  • Since version: 3.3.0
