Subject [jira] Created: (OPENJPA-173) JOIN in subselect generates bad SQL
Date Wed, 14 Mar 2007 00:40:09 GMT
JOIN in subselect generates bad SQL
-----------------------------------

                 Key: OPENJPA-173
                 URL: https://issues.apache.org/jira/browse/OPENJPA-173
             Project: OpenJPA
          Issue Type: Bug
          Components: sql
    Affects Versions: 0.9.6
            Reporter: Roger Keays


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]
