executeHQL

public JsonRpcMessage<Object> executeHQL(String persistenceUnit,
 String hql,
 Integer pageNumber,
 Integer pageSize)

Execute an arbitrary hql query in the given persistence unit. The query might be both a selection or a mutation statement. For selection queries, the result count is retrieved though a count query and the results, paginated based on pageNumber and pageSize are returned. For mutation statements, a custom message including the number of affected records is returned.

This method handles result serialization (to JSON) internally, and returns a JsonRpcMessage<String> to avoid further processing by the JsonRpcRouter.

Parameters:

persistenceUnit - The name of the persistence unit within which the query will be executed

hql - The Hibernate Query Language (HQL) statement to execute

pageNumber - The page number, used for selection query results pagination

pageSize - The page size, used for selection query results pagination

Returns:

a JsonRpcMessage<String> containing the resulting HibernateOrmDevJsonRpcService.DataSet serialized to JSON.
