How to enable the MySQL BINARY operator in Hibernate queries and Session.get()

Question

Is it possible to fetch the record using HQL against MySQL with a query like this?

 select * from students where binary sid='s001' 

I am using hibernate 4.3 and this BINARY operator is not recognized by Hibernate. If I want to achieve the same with Session.get() , what do I have to do?

Answer 1

Both MySQL and HQL support the CAST() function so you can rewrite your query as:

select * 
from students 
where CAST(sid as binary) = CAST('s001' as binary) 

For Session.get() you need to use the @Loader Hibernate custom annotation. You can find more on the @Loader usage here.
