How to call a stored procedure? I have read some questions in this forum and I got this:

From my java code I could do:

Query query = sesion.getNamedQuery("procedure_SP");

And in the hbm file:

<sql-query name="procedure_SP" callable="true">
<return alias="InfoUser" class="mx.uam.hibernate.InfoUser"/>
{call selectTestInfoUser_sp(?)}
</sql-query>

1. is this right?
2.If my store procedure has 1 one parameter out and three parameters in in this order, this line
{call selectTestInfoUser_sp(?)} should turn into ?

Thanks
