org.apache.torque.criteria.FromElement
This class describes an Element in the From-part of a SQL clause. It must contain the name of the database table. It might contain an alias for the table name, a join type a join condition and prepared statement replacements. The class is immutable.
org.hibernate.hql.ast.tree.FromElement
Represents a single mapped class mentioned in an HQL FROM clause. Each class reference will have the following symbols:
- A class name - This is the name of the Java class that is mapped by Hibernate.
- [optional] an HQL alias for the mapped class.
- A table name - The name of the table that is mapped to the Java class.
- A table alias - The alias for the table that will be used in the resulting SQL.
