One to Many search using AND condition

Question

I have the following product which contain many colors.

I wish to find the product which contain at least RED and GREEN.

Product class

    String id;

          


        

Answer 1

the idea is we select all products with the colors and count each product, then products with both colors should have a count of 2 as the number of colors

DetachedCriteria colorCrit = DetachedCriteria.For(Product.class)
    .createAlias("colors","color")
    .add(Restriction.eq("color.color", "RED")
    .add(Restriction.eq("color.color", "GREEN")
    .SetProjection(Projections.Group("id"))
    .add(Restriction.eq(Projections.rowCount(), 2));

Criteria criteria = createCriteria()
    .add(Subqueries.in("id", colorCrit)
    .list();

Update:

there is an issue for hibernate for exactly this. the last comment describes how to use.
