Subject Re: Fw: Hive update operation
Date Fri, 26 Aug 2016 06:17:53 GMT
Ok this is what you have in MSSQL (COLLATE) does not come into it in Hive)

UPDATE table1
SET

address=regexp_replace(t2.cout_event_description,'''''''','''')
            , latitude=t2.latitude
            , longitude=t2.longitude
            , speed =t2.speed
            , dtimestamp =mv.dtimestamp
            , reg_no=t2.registration
            , gpsstate = t2.bgps
FROM
              default.maxvalues  mv
            , table2 t2
INNER JOIN table2 t2 on  mv.dtimestamp=t2.dtimestamp AND
mv.acqnum=t2.acqnum INNER JOIN table1 t1 on mv.acqnum=t1.deal_number
where t1.deal_number=mv.acqnum;

Simplify this in Hive and test

CREATE TEMPORARY TABLE tmp1
AS
SELECT <all columns needed including JOIN columns with table1)
FROM
 table2 t2, default.maxvalues mv
WHERE mv.dtimestamp=t2.dtimestamp AND mv.acqnum=t2.acqnum

UPDATE table1
SET

address=regexp_replace(t2.cout_event_description,'''''''','''')
            , latitude=tmp1.latitude
            , longitude=tmp1.longitude
            , speed =tmp1.speed
            , dtimestamp =tmp1.dtimestamp
            , reg_no=tmp1.registration
            , gpsstate = tmp1.bgps
FROM
            tmp1, table1 t1
WHERE       tmp1.acqnum = tmp1.deal_number
