Description

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]}
