org.eclipse.persistence.jpa.jpql.parser.UpdateClause
This is the update clause of the update statement.
An UPDATE 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: update_clause ::= UPDATE abstract_schema_name [[AS] identification_variable] SET update_item {, update_item}*
