Hi, Stuart,
The error message "Cannot perform an update or delete operation on select
query" suggests that openjpa thinks your query is a select operation, and
therefore when executeUpdate is called on this query, openjpa does not know how
to update/delete on the select statement.
There are a couple of reason why openjpa will think a query is a select
statement. The following is one example:
Query query = em.createNativeQuery("update BasicA set name = ? where id =?",
BasicA.class);
Note that the result class (BasicA.class) is provided as an extra input
parameter to the createNativeQuery api. For this query object, if you call
executeUpdate on it, you will get "Cannot perform an update or delete operation
on select query" error. You might want to check your code to see exactly how
the native query is created.
Regards,
Fay

Re: Native Query: Update fails with InvalidStateException
Hi,
I could not reproduce this problem against DB2. Which database are you
using? also,can you post your persistence.xml to see if there is any special
setting?
