Has anyone come across the following problem in JPA/Hibernate/Spring:

I have a persisted instance of a class MyClass which contains a Float instance variable, f, mapped to a database FLOAT type (either Oracle or H2). The value of f is 123.456.

I execute the following code:


Which prints "1" when run with an Oracle database (which is what I would expect), but "0" with H2.

What's more, on H2, when I remove the ROUND function and just query on "myClass.f = ?1" I get one result as expected, which suggests ROUND is the problem. But also when I leave ROUND there, and hardcode the parameter ?1 as "123.456" I also get one result, which suggests it's the setting of the parameter that's the problem!!!

Can anyone enlighten me as to what's going wrong here?
