Basic predicates
A basic predicate compares two values.
Basic predicates can be of two forms, for example:
expression-1 comparison-operator expression-2expression-3 comparison-operator ( subselect )The subselect must not return more than one value and the subselect cannot return a type of an EJB reference. Boolean types and reference types only support = and <> comparisons.
Example: Basic predicates
d.name='Java Development' e.salary > 20000 e.salary > ( select avg(e.salary) from EmpBean e)
