> As reported at openjpa-dev [1], the following query generates invalid SQL:
>     UPDATE Email e SET e.totalDeliveries = e.totalDeliveries + 1
>     WHERE e.email IN (
>         SELECT m.email FROM MailingList l JOIN l.subscribers m)
> OpenJPA (0.9.6) parses this correctly, but can't seems to be missing the JOIN clause
or some table names from the generated SQL:
>  org.apache.openjpa.lib.jdbc.ReportingSQLException: ERROR: syntax error at or near "WHERE"
{prepstmnt 27475707 UPDATE FB_EMAILS SET totalDeliveries = (totalDeliveries + ?) WHERE email
IN (SELECT DISTINCT t2.email FROM WHERE (t2.email IN (SELECT t3.email FROM FB_EMAILS t3 WHERE
t0.id = t1.id AND t1.subscribers_email = t3.email))) [params=(long) 1]} [code=0, state=42601]
