Literals in JPQL, as in Java, represent constant values. JPQL supports various types of literals , including NULL , boolean literals ( TRUE and FALSE ), numeric literals (for example, 100 ), string literals (for example, 'abc' ), enum literals (for example, mypackage.MyEnum.MY_VALUE ), and entity

Jakarta Persistence (JPA) Method in jakarta.persistence.criteria.CriteriaBuilder Expression literal (    T value ) Create an expression for a literal .

String values can appear in JPQL queries in several forms: As string literals , for example, 'abc ... a path expression), and the right operand is the pattern (usually a parameter or literal ).

Predicate p = cb. notEqual (e. type (), cb. literal ... (which can represent any path, including a root or a join) and the entity type Country , which is a criteria literal .

Date and time expressions can appear in JPQL queries in the following ways: As date and time literals --for example, {d '2011-12-31'} and {t '23:59:59'} . As parameters --when date and time values ... ts = cb. currentTimestamp (); // both Unlike constant date literals , which are built

the primary key is used as a literal , which means that the query has to be compiled every time and the query program cache cannot be used. Maybe ObjectDB should optimize such queries replacing literals ... . So ObjectDB would indeed cache this query the way it is? Please ignore my original post - the literals
