How to make a good JPA query-CodePudding

I have this problem with JPA Query. DER

Customers make purchases and can purchase products with a limit of 1 unit per purchase per day. This is my JPQL code:

@Query("SELECT p FROM Producto p where p.idProducto not in (SELECT c.detalles FROM Compra c"
      " JOIN c.detalles det"   " where (c.cliente=?1 and (DATE(c.fecha) = CURRENT_DATE()))"
      " GROUP BY det.id_producto"   " HAVING (sum(det.cantidad<=1)))")
List<Producto> getProductosHabilitadosPorCliente(int idCliente);

ERROR: expecting CLOSE, found '<=' near line 1, column 278.

Thanks!!

The solution: @Query("SELECT p FROM Producto p WHERE p.idProducto NOT IN (SELECT d.producto FROM Compra c JOIN c.detalles d WHERE ((c.cliente.idCliente=?1) AND (DATE(c.fecha)=CURRENT_DATE())) GROUP BY d.producto HAVING SUM(d.cantidad)>=3")")
