Hive equivalent of sql update - hive

I am trying to convert below query equivalent to hive.
updating tier_cd in rpt table but hive 0.13 doesn't support update so using the changing to hive equivalent and output is not correct.
UPDATE test_report A
SET TIER_CD = (SELECT B.TIER_CD FROM lk B
WHERE B.CLASS_CD = A.CLASS_CD AND B.RC_TYPE_CD = 'OATS'
AND A.ACPTD_ROE_CT >= B.BEGIN_QT
AND A.ACPTD_ROE_CT <= B.END_QT
AND EFCTV_DT = (SELECT MAX(C.EFCTV_DT) FROM LK C WHERE
C.CLASS_CD = B.CLASS_CD AND C.RC_TYPE_CD = 'OATS' AND
C.TIER_CD = B.TIER_CD AND
C.EFCTV_DT <= ?
AND B.TIER_CD <> 'I')
WHERE A.YEAR_CD = ?
AND A.MONTH_CD = ?;
HIve equivalent is below
select z.*,x.tier_Cd from
(
select * from test_report
where year_Cd=?
and month_Cd=?')z
left outer join
(SELECT B.TIER_CD TIER_cD, A.MKT_CLASS_CD,A.year_cd FROM LK B, test_report A
WHERE B.CLASS_CD = A.CLASS_CD AND B.RC_TYPE_CD = 'OATS'
AND A.ACPTD_ROE_CT >= B.BEGIN_QT
AND A.ACPTD_ROE_CT <= B.END_QT
AND EFCTV_DT = (SELECT MAX(C.EFCTV_DT) FROM LK C WHERE
C.CLASS_CD = B.CLASS_CD AND C.RC_TYPE_CD = 'OATS' AND
C.TIER_CD = B.TIER_CD AND
C.EFCTV_DT <= ?)
AND B.TIER_CD <> 'I')x
on(z.class_Cd=x.Class_Cd)
please assist what's wrong in it.


Hive doesn't support multiple subqueries instead you can connect three tables with only joins. My guess is you're getting an error near select (max

ORA-00920: invalid relational operator for Merge

I am getting the
ORA-00920: invalid relational operator
message for below query. Please help on this.
MERGE INTO PS_CT_IQN_ACC_STG STG USING PS_CTS_IQN_BU_RATE RT ON (STG.BUSINESS_UNIT = RT.BUSINESS_UNIT)
WHEN MATCHED THEN
UPDATE
SET STG.STANDARD_RATE = RT.STANDARD_RATE,
STG.STANDARD_HOURS = RT.HOURS_PER_DAY,
STG.CURRENCY_CD = RT.CURRENCY_CD
WHERE STG.PROCESS_INSTANCE = 22195604
AND RT.EFFDT =
(SELECT MAX(EFFDT)
FROM PS_CTS_IQN_BU_RATE RT1
WHERE RT.BUSIN ESS_UNIT = RT1.BUSINESS_UNIT
AND RT1.EFFDT <= sysdate
)
AND STG.STANDARD_RATE = 0
AND STG.STANDARD_HOURS = 0
AND STG.BUSINESS_UNIT IN
( SELECT DISTINCT BUSINESS_UNIT FROM PS_CTS_IQN_BU_RATE
);

Try to run this query seperate first
SELECT MAX(EFFDT)
FROM PS_CTS_IQN_BU_RATE RT1
WHERE RT.BUSIN ESS_UNIT =
RT1.BUSINESS_UNIT
AND RT1.EFFDT <= sysdate
Use IN here, I guess max are multiples by the above query
..... AND RT.EFFDT = (select max...)

SQL Server Update from group by

I need to update the column of a temp table from the count of a field from another table. I was trying to do this with the following query, but I get a syntax error.
How should I write this query?
Thanks!
UPDATE #ResultadosTest
SET PalletsReservados = COUNT(pe.paen_numero)
FROM #ResultadosTest RT, dba.spro_palletencab pe
WHERE pe.pate_tempor = RT.pate_tempor
AND pe.expo_codigo = RT.expo_codigo
AND pe.WeekLinId = RT.WeekLinId
AND pe.plde_codigo = RT.plde_codigo
AND pe.paen_estado = 1
AND ISNULL(pe.LoteCargaId, 0) <> 0
AND ISNULL(pe.PREMOPID, 0) <> 0
GROUP BY
pe.pate_tempor, pe.expo_codigo, pe.WeekLinId, pe.plde_codigo
The error is:
Line 10, Incorrect syntax near the keyword 'GROUP' (42000,156)

You can't directly use an aggregate function at update statement. Instead you can you a derived table
Update #ResultadosTest
SET PalletsReservados = ppp.countpaen_numero
From (Select Count(pe.paen_numero) as countpaen_numero ,pe.pate_tempor,spro_palletencab,........
FROM #ResultadosTest RT,dba.spro_palletencab pe
Where pe.pate_tempor=RT.pate_tempor
AND pe.expo_codigo=RT.expo_codigo
AND pe.WeekLinId=RT.WeekLinId
AND pe.plde_codigo=RT.plde_codigo
AND pe.paen_estado=1 AND IsNull(pe.LoteCargaId,0)<>0 AND IsNull(pe.PREMOPID,0)<>0
GROUP BY pe.pate_tempor,pe.expo_codigo,pe.WeekLinId,pe.plde_codigo ) ppp
Where ppp.pate_tempor = Field..

First group, then join
Update #ResultadosTest
SET PalletsReservados = pe.Cnt
FROM #ResultadosTest RT
JOIN (
SELECT pate_tempor, expo_codigo, WeekLinId, plde_codigo, Count(pe.paen_numero) cnt
FROM dba.spro_palletencab pe
WHERE paen_estado=1 AND IsNull(LoteCargaId,0)<>0 AND IsNull(PREMOPID,0)<>0
GROUP BY pate_tempor,expo_codigo,WeekLinId,plde_codigo
) pe ON pe.pate_tempor=RT.pate_tempor
AND pe.expo_codigo=RT.expo_codigo
AND pe.WeekLinId=RT.WeekLinId
AND pe.plde_codigo=RT.plde_codigo;

should work like:
UPDATE RT
SET PalletsReservados = pe.ctr
FROM #ResultadosTest RT
INNER JOIN
(
SELECT pate_tempor
,expo_codigo
,WeekLinId
,plde_codigo
,Count(pe.paen_numero) as ctr
FROM dba.spro_palletencab
WHERE paen_estado = 1
AND ISNULL(LoteCargaId,0) <> 0
AND ISNULL(PREMOPID,0) <> 0
GROUP BY pe.pate_tempor
,pe.expo_codigo
,pe.WeekLinId
,pe.plde_codigo
) pe
ON pe.pate_tempor = RT.pate_tempor
AND pe.expo_codigo = RT.expo_codigo
AND pe.WeekLinId = RT.WeekLinId
AND pe.plde_codigo = RT.plde_codigo

issue in converting oracle join query to ansi syntax

I am trying to convert the below mentioned query to ansi format
oracle query :
SELECT *
FROM table_1 a,
table_2 b,
table_2 c
WHERE c.dt(+) = a.dt
AND c.ap_no(+) = a.ap_no
AND c.jy_no(+) = a.jy_no
AND c.tn(+) = a.tn
AND b.dt(+) = a.dt
AND b.ap_no(+) = a.ap_no
AND b.jy_no(+) = a.jy_no
AND ( b.t_no(+) + 1 ) = a.t_no --> unable to understand this part
AND ( b.type_cd(+) = 100
AND c.type_cd(+) = 200);
ansi format :
select * from
table2 c right outer join table1 a on
c.dt = a.dt
and c.ap_no = a.ap_no
and c.jy_no = a.jy_no
and c.tn = a.tn
left outer join table2 b on
a.dt = b.dt
and a.ap_no = b.ap_no
and a.jy_no = b.jy_no
and a.t_no = b.t_no ------------------> wrongly implemented it
where b.type_cd = 100 and c.type_cd = 200;
I am not understanding, how to convert the +1 found in the "unable to understand this part" of the Oracle query to the ansi format. Please advise.
Edit : this is not fully similar to the problem explained here . I am just trying to understand the +1 part of the query.

Teradata 3706, expected something between DISTINCT and LEFT keyword

I am here trying to use UPDATE query with JOIN and SELECT, But I am facing 3706 error.
here is the error line -
UPDATE A0619IL3549_D_RPT.RPT_IS_ELIGIBILITY A2
FROM
(SELECT A.REP_CD, A.GEO_CD,A.MONTH_ID, B.IC_PRD AS IC_PAYOUT_FLAG,
COALESCE(CASE
WHEN UPPER(B.IC_PRD) = 'SEMESTERLY' THEN A.CURR_SEMESTER_FLAG
WHEN UPPER(B.IC_PRD) = 'QUARTERLY' THEN A. CURR_QUARTER_FLAG
ELSE '0'
END,'0') IC_PAYOUT_FLAG
FROM
A0619IL3549_D_RPT.RPT_IS_ELIGIBILITY A,
(
SELECT DISTINCT LEFT(B. REP_CD, POSITION('-' IN B.REP_CD)-1) AS REP_CD,C.GEO_CD,IC_PRD FROM

WHERE
A.REP_SK=B.REP_SK
AND A.GEO_SK=C.GEO_SK
AND A.RUN_ID = (SELECT MAX(RUN_ID) FROM A0619IL3549_D00_IC_MAIN.ICDM_GEO_REP_PROD)
) B
WHERE
A.REP_CD = B.REP_CD
AND
A.GEO_CD = B.GEO_CD)A1
SET A2.IC_PAYOUT_FALG = A1.IC_PAYOUT_FLAG
WHERE
A1.REP_CD = A2.REP_CD
AND
A1.MONTH_ID = A2.MONTH_ID
AND
A.GEO_CD = A2.GEO_CD

LEFT is not a valid Teradata function before TD15.10, it's ODBC SQL, which is automatically translated, but only for SELECT.
Use valid syntax instead:
SUBSTRING(B. REP_CD FROM 1 FOR POSITION('-' IN B.REP_CD)-1)

The format for a merge statement is:
merge into <target_table> tgt
using <table_name or subquery> src
on (<join conditions between the target and source datasets>)
when matched then
update set ...
when not matched then
insert (...)
values (...);
Quite apart from the fact that your source subquery is incorrect (there are errors around where the t1 and t2 are; too many brackets, inappropriately trying to alias something etc), whilst you have join conditions inside your subquery, you're completely missing the ON clause for the merge itself.
You need to define the join conditions that match the data returned by your source subquery to your target table.

Now the error is : src.ga - Invalid Identifier
