below code
$getQueList = mysql_query("SELECT * FROM questions_master order by questions_master.question_id desc LEFT JOIN users_master ON questions_master.userId = users_master.userId ");
I want to get result as per questions_master.question_id in descending order
Here is the query you have to use for getting result questions_master.question_id in descending order
SELECT *
FROM questions_master
LEFT JOIN users_master
ON questions_master.userId = users_master.userId
ORDER BY questions_master.question_id desc
Order by clause comes at the end.

Anyone please help me, how to uniqe each row
SELECT T3.ID_JS,T5.DIVISI_AREA,T4.NAME_METHODE_REPAIR, T1.URUTAN AS SORT, TO_DATE(T1.TIME_FINISHED_WORK,'DD/MM/YYYY') AS DATE_FINISHED
FROM TB_WORK T1
JOIN TB_INSPECTION T2 ON T1.ID_INSPECTION=T2.ID_INSPECTION
JOIN TB_JOBSHEET T3 ON T2.ID_JS = T3.ID_JS
JOIN TB_METHODE_REPAIR T4 ON T1.ID_METHODE_REPAIR=T4.ID_METHODE_REPAIR
JOIN TB_DIVISI T5 ON T1.ID_DIVISI=T5.ID_DIVISI
where t3.id_js=142414
GROUP BY T3.ID_JS,T5.DIVISI_AREA,T4.NAME_METHODE_REPAIR, T1.URUTAN,TO_DATE(T1.TIME_FINISHED_WORK,'DD/MM/YYYY')
ORDER BY T3.ID_JS, TO_DATE(T1.TIME_FINISHED_WORK,'DD/MM/YYYY') desc
[Result] (http://prntscr.com/sfpuuq)
Those rows are unique, so I'll guess: there are two rows with sort = 3 and you'd want to have only one. If that's so, regarding the fact that date value is the only thing that makes difference, a simple way is to use aggregate function (such as min or max). I used max, but you can change it if you want:
SELECT t3.id_js,
t5.divisi_area,
t4.name_methode_repair,
t1.urutan AS sort,
MAX (TO_DATE (t1.time_finished_work, 'DD/MM/YYYY')) AS date_finished
FROM tb_work t1
JOIN tb_inspection t2 ON t1.id_inspection = t2.id_inspection
JOIN tb_jobsheet t3 ON t2.id_js = t3.id_js
JOIN tb_methode_repair t4
ON t1.id_methode_repair = t4.id_methode_repair
JOIN tb_divisi t5 ON t1.id_divisi = t5.id_divisi
WHERE t3.id_js = 142414
GROUP BY t3.id_js,
t5.divisi_area,
t4.name_methode_repair,
t1.urutan
ORDER BY t3.id_js, date_finished DESC
You'd remove date column from GROUP BY; besides, if you wanted to select distinct rows, why didn't you apply select distinct instead of using group by? Result is the same, but - group by is generally used with aggregates, not to return distinct result.
I have a sql that is selecting many things from the database however I would like that data to only comeback which is matched to a personal table I have.
I would like to join a column [vin_code] from my table [population] however there are nulls in here and were there are nulls I would like to join another column from my table to another table in the database.
I will give an example sql below:
Select distinct v.kegal_rntity_id
From vin v
Inner join ops$dami.population pop
On v.vin_code = pop.vin_code
Then were pop.vin_code is null I would like to join pop.vis_code on a table in the database called zegal_rentity z column z.vis_code
So something like
join zegal_rentity z
On pop.vis_code = z.vis_code
But I only want to do this were pop.vin_code is null
As sample data is not available, I am unable to test the solution but try the following query with condition based outer join.
Select distinct v.kegal_rntity_id
From ops$dami.population pop
Left join vin v
On v.vin_code = pop.vin_code
Left join zegal_rentity z
On (case when pop.vin_code is null and
pop.vis_code = z.vis_code then 1 end = 1);
Cheers!!
I have only been using Toad/Oracle for a few weeks so am still learning coding etc I have knowledge of SQL Code in Access and trying to now learn Oracle.
I need to return the max date from UCMRBILDAT from tbl BIC/AZUCDMO0100 but only from contracts which are contained in linked tbl LH_DAT
I have also tried a having MAX UCMRBILDAT but this didnt work.
UCMRBILDAT (/BIC/AZUCDMO0100)
UC_MRESULT (/BIC/AZUCDMO0100)
UC_MRSTAT (/BIC/AZUCDMO0100
UC_MRCAT (/BIC/AZUCDMO0100)
CONTRACT_NUMBER (LH_DAT)
UC_MR_NUMB (/BIC/AZUCDMO0100) + (/BIC/AZUCDMO0200)
SELECT UCMRBILDAT,
UC_MRESULT,
UC_MRSTAT,
UC_MRCAT
FROM LH_DAT
( SELECT CONTRACT_NUMBER, MAX (UCMRBILDAT) MXBD
FROM SAPSR3."/BIC/AZUCDMO0100"
GROUP BY CONTRACT_NUMBER) GMR
LEFT OUTER JOIN SAPSR3."/BIC/AZUCDMO0200"
ON (CONTRACT_NUMBER = UCCONTRACT)
INNER JOIN SAPSR3."/BIC/AZUCDMO0100"
ON ("/BIC/AZUCDMO0200".UC_MR_NUMB = "/BIC/AZUCDMO0100".UC_MR_NUMB)
WHERE CONTRACT_NUMBER = '2000014420'
AND UCMRBILDAT = MXBD
AND MR.CONTRACT_NUMBER = GMR.CONTRACT_NUMBER
Max bill date from BIC/AZUCDMO0100 but only for contracts contained in table LH_DAT
EDIT NEED MAX DATE FOR UCMRBILDAT ON BELOW SCRIPT
SELECT CONTRACT_NUMBER,
UCMRBILDAT,
UC_MRESULT,
UC_MRCAT
FROM LH_DAT
LEFT OUTER JOIN SAPSR3."/BIC/AZUCDMO0200"
ON (CONTRACT_NUMBER = UCCONTRACT)
INNER JOIN SAPSR3."/BIC/AZUCDMO0100"
ON ("/BIC/AZUCDMO0200".UC_MR_NUMB = "/BIC/AZUCDMO0100".UC_MR_NUMB)
WHERE CONTRACT_NUMBER = '2000014420'
AND "/BIC/AZUCDMO0200".SOURSYSTEM = 'SP'
AND "/BIC/AZUCDMO0200".UCDELE_IND <> 'X'
To get the max value of "BIC/AZUCDMO0100".UCMRBILDAT where there's a linked value from LH_DAT you'd want to use:
SELECT MAX(ba.UCMRBILDAT)
FROM SAPSR3."BIC/AZUCDMO0100" ba
INNER JOIN LH_DAT ld
ON ld.some_field = ba.some_field
There must be fields which link "BIC/AZUCDMO0100" and LH_DAT together, but in your query they're not specified. Find those fields, plug them in to the query above, and you should get the result you're looking for.
I have expression with db_link to MS SQL:
select b."Str" as "State" ,a."_Fld9059" as "Date" from
"_InfoRg9050"#SQLSERVER.UISLAB.COM a INNER JOIN
"EnumTexts"#SQLSERVER.UISLAB.COM b
on a."_Fld9052RRef" = b."_IDRRef"
where a."_Fld10998" = '1104000009' and
a."_Fld10998" = to_date(max(a."_Fld9059"),'dd.mm.yyyy')
order by a."_Fld9059" desc;
I want to upload value with maximum date. Can anybody help me ?
When I run this query I get ORA-00934 error.
The immediate cause of the error you are getting is that MAX() appears in the WHERE clause. One possible workaround, which might be what you intended, would be to use a subquery in the WHERE clause to identify the maximum date:
SELECT b.Str AS State,
a._Fld9059 AS Date
FROM _InfoRg9050 a
INNER JOIN EnumTexts b
ON a._Fld9052RRef = b._IDRRef
WHERE a._Fld10998 = '1104000009' AND
a._Fld10998 = (SELECT MAX(TO_DATE(_Fld9059, 'dd.mm.yyyy')) FROM _InfoRg9050)
ORDER BY a._Fld9059 DESC
However, it is not clear why you are comparing _InfoRg9050._Fld10998 to both the string '1104000009' and a date. You will need to resolve this on your own I believe to get a meaningful result.
Thank you for your help. I got it.
SELECT b."Str" AS "State"

INNER JOIN "EnumTexts"#SQLSERVER.UISLAB.COM b
on a."_Fld9052RRef" = b."_IDRRef"

Trying to retrive the MAX doc in the right table.
SELECT F43.PDDOCO,
F43.PDSFXO,

F431.PRAREC/100,
max(F431.PRDOC)
FROM PRODDTA.F43121 F431
LEFT OUTER JOIN PRODDTA.F4311 F43
ON

AND F43.PDDOCO=F431.PRDOCO
AND F43.PDDCTO=F431.PRDCTO
AND F43.PDSFXO=F431.PRSFXO

Group by

This query is still returning the two rows in the right table. Fairly new to SQL and struggling with the statement. Any help would be appreciated.
Without seeing your data it is difficult to tell where the problem might so I will offer a few suggestions that could help.
First, you are joining with a LEFT JOIN on the PRODDTA.F4311 but you have in the WHERE clause a filter for that table. You should move the F43.PDLNTY = 'DC' to the JOIN condition. This is causing the query to act like an INNER JOIN.
Second, you can try using a subquery to get the MAX(PRDOC) value. Then you can limit the columns that you are grouping on which could eliminate the duplicates. The query would them be similar to the following:
SELECT F43.PDDOCO,
F43.PDSFXO,
F43.PDLNID,
F43.PDAREC/100 As Received,
F431.PRAREC/100,
F431.PRDOC
FROM PRODDTA.F43121 F431
INNER JOIN
(
-- subquery to get the max
-- then group by the distinct columns
SELECT PDKCOO, max(PRDOC) MaxPRDOC
FROM PRODDTA.F43121
WHERE PRDOCO = 401531
and PRMATC = 2
GROUP BY PDKCOO
) f2
-- join the subquery result back to the PRODDTA.F43121 table
on F431.PRDOC = f2.MaxPRDOC
AND F431.PDKCOO = f2.PDKCOO
LEFT OUTER JOIN PRODDTA.F4311 F43
ON F43.PDKCOO=F431.PRKCOO
AND F43.PDDOCO=F431.PRDOCO
AND F43.PDDCTO=F431.PRDCTO
AND F43.PDSFXO=F431.PRSFXO
AND F43.PDLNID=F431.PRLNID
AND F43.PDLNTY = 'DC' -- move this filter to the join instead of the WHERE
WHERE F431.PRDOCO = 401531
and F431.PRMATC = 2
If you provide your table structures and some sample data, it will be easier to determine the issue.
