@ComponentSpecification public interface JpqlStatementFactory extends StatementFactory
StatementFactory for Jpql.
There is no INSERT support as JPQL does not have insert statements.| Modifier and Type | Method and Description |

selectFrom(EntityAlias<?> alias,
Class<E> toClass,

Creates
SelectStatement for a projection to a transfer-object having an according constructor. |
JpqlSelectStatement<Object[]> |
selectFrom(EntityAlias<?> alias,

FeatureSelectSelectStatement for a projection to a transfer-object having an according constructor. In JPA this
is called a constructor query (
SELECT NEW package.Classname(arg1, arg2, ...) FROM alias.source [AS alias.name] ...). If not natively
supported this is implemented as a projection based on a tuple

matching to the value types of the constructorArgs.constructorArgs - the selection paths (or aggregate expressions).SelectStatement.<E> JpqlDeleteStatement<E> deleteFrom(EntityAlias<E> alias)
