Basic predicates

Basic predicates can be of two forms

expression-1  comparison-operator  expression-2
expression-3  comparison-operator ( subselect )

The subselect must not return more than one value and the subselect can not 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)
