I have a namedquerie :

@NamedQuery(name=JuntaPreEnsamble.QUERY_ESTRUTURA_JUNTA_PREENSAMBLE, query=" from CorteBiselado as cb left join cb.estruturaPlano as ep where "+
" ep.fabrica= :fabrica " +
" and ep.posicaoMargem= :posicaoMargem " +
" and ep.modulo= :modulo " +
" and ep.subModulo= :subModulo " +
" and ep.tramo= :tramo " +
" and ep.componente= :componente " +
" and ep.elemento = :elemento " +
" and ep.posicaoElemento = :posicaoElemento")

This sentence is returning entities "CorteBiselado" and "EstruturaPlano" ...

I wish the sentence returns only the entity "CorteBiselado"

How could I make a sentence?

You should try:

query="select ep from CorteBiselado as cb left join cb.estruturaPlano as ep

att,

thanks ,,,, work well
