org.eclipse.persistence.jpa.jpql.parser.DeleteClause
This is the delete clause of the delete statement.
A DELETE statement provides bulk operations over sets of entities of a single entity class (together with its subclasses, if any). Only one entity abstract schema type may be specified in the UPDATE clause.

BNF: delete_clause ::= DELETE FROM abstract_schema_name [[AS] identification_variable]
Example: DELETE FROM Employee e @version 2.4.2 @since 2.3 @author Pascal Filion
