Hi, I am getting "Commit or rollback is not allowed within a trigger" under H2 1.3.176 but I am not actually rolling anything back. As far as I understand the following sequence of events occurs:
1. Java code invokes: delete from PARTICIPANT where PARTICIPANT.LAST_SEEN_TIME < ? 2. A "after delete" trigger runs, invoking: delete from PERMISSION where ID = ? (at CascadeToPermission.java:80) 3. This triggers a rollback (looking at the H2 source code, caused by a deadlock) 4. H2 throws the following exception: com.mysema.query.QueryException: Caught JdbcSQLException for delete from PARTICIPANT where PARTICIPANT.LAST_SEEN_TIME < ? at com.mysema.query.sql.DefaultSQLExceptionTranslator.translate(DefaultSQLExceptionTranslator.java:38) ~[querydsl-sql-3.4.0.jar:na] at com.mysema.query.sql.Configuration.translate(Configuration.java:434) ~[querydsl-sql-3.4.0.jar:na] at com.mysema.query.sql.dml.SQLDeleteClause.execute(SQLDeleteClause.java:165) ~[querydsl-sql-3.4.0.jar:na] at com.vtlr.backend.row.Participant.removeOlderThan(Participant.java:262) ~[classes/:na] at com.vtlr.backend.jersey.LifecycleListener$RemoveIdleParticipants.run(LifecycleListener.java:299) ~[classes/:na] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) [na:1.8.0_05] at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) [na:1.8.0_05] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) [na:1.8.0_05] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) [na:1.8.0_05] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [na:1.8.0_05] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [na:1.8.0_05] at java.lang.Thread.run(Thread.java:745) [na:1.8.0_05] Caused by: org.h2.jdbc.JdbcSQLException: Commit or rollback is not allowed within a trigger; SQL statement: delete from PARTICIPANT where PARTICIPANT.LAST_SEEN_TIME < ?

Is this a bug? If not, what am I supposed to do? Thanks, Gili -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
