I am trying to run below query;

    left outer join DIM_deviceVersion ext8 on
(ext8.DIM_ID=3Dtbl.deviceversion)
    left outer join DIM_operator ext9 on (ext9.DIM_ID=3Dtbl.operator)    =

ORDER BY
    tbl.id ASC

throws;

WHERE
    tbl.devicemakemodel=3Dext6.DIM_ID AND tbl.deviceplatformtype=3Dext7.DIM=
_ID
AND tbl.deviceversion=3D
    ext8.DIM_ID AND tbl.operator=3Dext9.DIM_ID
ORDER BY

works btw...
Thanks.

Hello

this is not a bug report.

please, send your query to pg_general mailing list

probably better - ask on gridsql mailing list

Why the query is different in Exception?
Can you try with=20
SELECT
     tbl.id,
     tbl.day,
     tbl.week,
     tbl.appfailure,
     tbl.appname,
     tbl.deviceid,
     ext6.DIM_NAME,
     tbl.starttime
 FROM
     APPSTARTEVT tbl
     left outer join DIM_deviceMakeModel ext6 on
    (ext6.DIM_ID=3Dtbl.devicemakemodel)
    ORDER BY   tbl.id ASC

Also as Pavel has pointed, send this to General mailing list.=20

Does this query work if you copy it from the exception message and execute
it in psql?

If so, then the problem is somewhere in the Java domain, between gridsql
and jdbc.

If not, you'll probably get a more informative error out of it ;)
