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
- Name:
STARTS_WITH - SQL semantic:
expr1 LIKE 'expr2%' - Since version: 3.3.0
- Name:
ENDS_WITH - SQL semantic:
expr1 LIKE '%expr2' - Since version: 3.3.0
- Name:
CONTAINS - SQL semantic:
expr1 LIKE '%expr2%' - Since version: 3.3.0
- Name:
IN - SQL semantic:
expr IN (expr1, expr2, ...) - Since version: 3.3.0
- Name:
= - SQL semantic:
expr1 = expr2 - Since version: 3.3.0
- Name:
<> - SQL semantic:
expr1 <> expr2 - Since version: 3.3.0
- Name:
<=> - SQL semantic: null-safe version of
expr1 = expr2 - Since version: 3.3.0
- Name:
< - SQL semantic:
expr1 < expr2 - Since version: 3.3.0

NOT expr - Since version: 3.3.0
- Name:
ALWAYS_TRUE - SQL semantic:
TRUE - Since version: 3.3.0
