Hibernate: how to call a stored function returning a varchar?

Question

I am trying to call a legacy stored function in an Oracle9i DB from Java using Hibernate. The function is declared like this:

create or replace FUNCTION Tran         


        

Answer 1

callable = true is for calling stored procedures with {? = call ...()} syntax. Oracle's select ... from dual syntax is a normal query, so you don't need callable = true:

 
     
    select Transferlocation_Fix(:mnemonic) as retVal from dual
