Differerence between hibernate types: boolean, yes_no, true_false

Question

When to use each? To what do they map in the database?

Answer 1

from Hibernate: http://docs.jboss.org/hibernate/stable/core.old/reference/en/html_single/#mapping-types-basictypes

boolean , yes_no and true_false are all alternative encodings for a Java boolean or java.lang.Boolean.

Answer 2

Follow true_false , if you like T / F at database level. Otherwise, use yes_no , it will give you Y / N in the database.

By the way, got to know that there are some issues with these, which result in unexpected value. For example here and here , Few seems fixed already in successive updates, though.
