I am trying to run below query;

SELECT
    tbl.id,
    tbl.day,
    tbl.week,
    tbl.appfailure,
    tbl.appname,
    tbl.deviceid,
    ext6.DIM_NAME,
    ext7.DIM_NAME,
    ext8.DIM_NAME,
    ext9.DIM_NAME,
    tbl.starttime
FROM
    APPSTARTEVT tbl
    left outer join DIM_deviceMakeModel ext6 on
(ext6.DIM_ID=3Dtbl.devicemakemodel)
    left outer join DIM_devicePlatformType ext7 on
(ext7.DIM_ID=3Dtbl.deviceplatformtype)
    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;

Is there anything i am missing.

Query;

SELECT
    tbl.id,
    tbl.day,
    tbl.week,
    tbl.appfailure,
    tbl.appname,
    tbl.deviceid,
    ext6.DIM_NAME,
    ext7.DIM_NAME,
    ext8.DIM_NAME,
    ext9.DIM_NAME,
    tbl.starttime
FROM
    APPSTARTEVT tbl,    =

    DIM_deviceMakeModel ext6,
    DIM_devicePlatformType ext7,
    DIM_deviceVersion ext8,
    DIM_operator ext9
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
    tbl.id ASC

works btw...
Thanks.
