Looks nice.
Stupid question again from me - any reason why you use ?1 syntax and not just ? or :name here ?
(Just to keep the syntaxes for placeholders down at a minimum ,)
/max
This is committed now. To define a new function template you create an instance of SQLFunctionTemplate which implements SQLFunction and register it in a dialect as any other SQLFunction, e.g.
registerFunction("locate", new SQLFunctionTemplate(Hibernate.INTEGER, "locate(?1, ?2, ?3)"));
By the spec, this locate function might have 2 or 3 parameters. So, you define 3 in the template but can pass just 2.
If the template is not found for a specific dialect when generating SQL, the function will appear in the generated SQL as it appears in the EJB/H-QL statement. I.e. it is how it worked before.

Yes, sorry, of course, it is parsed like this. I had a bug in creating an argument list. It works now.
Thanks.
