Execute Custom function in H2 Console

[Lucky]

Hi:

    As some reason,I must utilize custom function in query sql .

    Just like this: select myId('myRule'),sname from tableA 

    I have define the custom function 'myid' with java code .

    And it  work running on client node.  

    But when I run the sql  in H2 Console, it got the wrong message: function 
'myId' not found.
    Do it support in H2 console ?
