Is this something we can put in 0.9.7 or has that been cut already?

+1 to remove the restriction. As long as no parameters are missing,
the query should be considered sufficient.

Seem fair enough to get rid of the description. I've opened
https://issues.apache.org/jira/browse/OPENJPA-196 describing the
+1 from me to remove the restriction that there be exactly as many
positional parameters declared as were assigned.

Actually, I think there is a bigger problem... Say I have a
query like this:
SELECT x FROM foo AS x WHERE foo.name = ?2
code assumes that if I have 1 parameter it is numbered ?1, but in
EJB 2.1 this was not a requirement and there are certification
tests that verify you are allowed to have "unused" parameters
(e.g, in my example about ?1 and ?N where N>2 are all not used).
I couldn't find any text in the specification that says that all
all positional parameters must be used in the query, but I did
find text that say the EJB-QL 3.0 language is an extension of the
EJB-QL 2.1 language:
"The Java Persistence query language is an extension of the
Enterprise Java Beans query language, EJB QL, definedin."
So I think we must remove the "extra-params" check, but I would
be happy with a "don't check for extra-params flag".

I'm working on a CMP 2 implementation that delegates to OpenJPA

org.apache.openjpa.persistence.ArgumentException : More

parameters were specified for query execution, but only 2
parameters were declared in the query.
In CMP you declare finder and select methods that have
parameters which are passed into the query engine. You can have
as many parameters as you like but are not required to use them
all, but it appears that OpenJPA is enforcing a restriction
where if the EJB-QL text only lists say 2 parameters and I set 4
I get the above exception. In order of perference:
Is this spec required? If not, can we remove the check?
Is there a way to disable the check? If so, how?
Is there a way to determine the number of paramters a query
takes? If so, I can change my code.
Is there a way to get the ejbql text from a Query object? If so,
I'll write a quick parser to determine number of queries myself.
BTW, I'm currently using 0.9.6.
