My problem is, when I run the following query in MySQL, it looks like this
Query;
SELECT
CONCAT(b.tarih, '#', CONCAT(b.enlem, ',', b.boylam), '#', b.aldigi_yol) AS IlkMesaiEnlemBoylamImei,
CONCAT(tson.max_tarih, '#', CONCAT(tson.max_enlem, ',', tson.max_boylam), '#', tson.max_aldigi_yol) AS SonMesaiEnlemBoylamImei,
Max(CAST(b.hiz AS UNSIGNED)) As EnYuksekHiz,
TIME_FORMAT(Sec_TO_TIME(TIMESTAMPDIFF(SECOND, (b.tarih), (tson.max_tarih))), '%H:%i') AS DurmaSuresi
FROM
(Select id as max_id, tarih as max_tarih, enlem as max_enlem, boylam as max_boylam, aldigi_yol as max_aldigi_yol from _213gl2015016424 where id in(
SELECT MAX(id)
FROM _213gl2015016424 where (tarih between DATE('2016-11-30 05:45:00') AND Date('2017-01-13 14:19:06')) AND CAST(hiz AS UNSIGNED) > 0
GROUP BY DATE(tarih))
) tson
LEFT JOIN _213gl2015016424 a ON a.id = tson.max_id
LEFT JOIN _213gl2015016424 b ON DATE(b.tarih) = DATE(a.tarih)
WHERE b.tarih is not null And (b.tarih between DATE('2016-11-30 05:45:00') AND Date('2017-01-13 14:19:06')) AND b.hiz > 0
GROUP BY tson.max_tarih
Output is order by date;

GROUP BY tson.max_tarih
Group by error is : To use the aggregate function, you must add the column "b.tarih" to the GROUP BY list.
When I add it I get the same error for another column.I'm waiting for your help.
You are using a feature of MySQL that is not standard SQL and you can also deactivate.
You are grouping by tson.max_tarih in your query. That means that for all rows that share the same value in that field, you will get only one row as a result of that group.
If you have several different values in the rest of the fields (enlem, boylam, etc...) which one are you trying to get in as the result of the query? That's the question that PostgreSQL is asking you.
MySQL is just returning any value for those fields among the rows in the group. PostgreSQL requires you to actually specify it.
Two typical solutions would be grouping by the rest of the fields (b.tarih, b.enlem) or specifying the value those fields to something like MAX(b.tarih), etc.

I need to insert createdate column twice with two different datatypes one with the datatype defined in the table itself and another in char datatype.
I can insert it by changing the alias name of createdate column but can't insert with same alias name which i need.
so help me out to get correct way of doing it.
My query:
SELECT DISTINCT TE.id, T.debatchqueuelink, TE.transactionlink,
EC.errorclassification, TE.errorvalue,
EC.errorparameter, TE.classificationlink, TE.description,
TE.createdate AS createdate, TO_CHAR(TE.createdate, 'MM/dd/yyyy') AS createdate,
TE.status, TE.rebutt, TE.rebuttedstatus, BQ.appbatchnumber,
BQ.scanbatchnumber, BQ.clientlink, BQ.locationlink, T.patientid,
(DEUD.firstname|| ' ' ||DEUD.lastname) AS deusername, DEUD.email AS deuseremail,

TE.decomment

INNER JOIN userdetail DEUD ON BQ.assignedto = DEUD.id
WHERE TE.inactive='t'
AND TE.status IN ('ERROR','QCCORRECTED')
LIMIT 0
The actual error message I am getting is:
Duplicate column:column "createdate" specified more than once
I get the error "select list expression Opportunity.id references which is neither grouped nor aggregated" when running the following query in BigQuery:
SELECT
Opportunity.id AS `Opportunity_Id`,
Opportunity.testing_only__c AS `Opportunity_Testing_only`,
MAX(DatedConversionRate.startdate) AS `DatedConversionRate_Start_date`,
FROM
`dataset.Opportunity` Opportunity
LEFT JOIN
`dataset.DatedConversionRate` DatedConversionRate
ON DatedConversionRate.isocode = Opportunity.currencyisocode
WHERE
DatedConversionRate.startdate < CURRENT_TIMESTAMP()
What is the problem and how can I fix it?
Remove Opportunity.id from select or group by it:
SELECT
Opportunity.id AS `Opportunity_Id`,
MAX(DatedConversionRate.startdate) AS `DatedConversionRate_Start_date`,
FROM
`dataset.Opportunity` Opportunity
LEFT JOIN
`dataset.DatedConversionRate` DatedConversionRate
ON DatedConversionRate.isocode = Opportunity.currencyisocode
WHERE
DatedConversionRate.startdate < CURRENT_TIMESTAMP()
GROUP BY Opportunity.id
I have just switched from mysql to postgresql and my working dql queries stopped working.
Here is my dql
SELECT p
FROM AppBundle:Photo p
JOIN AppBundle:Like l WITH p = l.photo
WHERE p.isModerated = :isModerated
AND p.isActive = :isActive
AND p.category IN(:categories)
AND p.creationDate <= :begin
AND p.creationDate >= :end
GROUP BY p.id
ORDER BY l.creationDate DESC
Getting the next error
SQLSTATE[42803]: Grouping error: 7 ERROR: column "l1_.creation_date" must appear in the GROUP BY clause or be used in an aggregate function
LINE 1: ... p0_.creation_date >= $4 GROUP BY p0_.id ORDER BY l1_.creati...
As i can understand, it says that group by column should be in SELECT. I dont it to be there. I need to select just p (AppBundle:Photo) and nothing more. What should be edited in dql to get it working properly?
Thank you.
I just replaced ORDER BY l.creationDate DESC to ORDER BY p.creationDate DESC
It will work for me. As i understood, ORDER BY column should be SELECTed

I am joining multiple files/tables together.
I have written the code in both DDS and SQL.
The DDS Logical File is working exactly as expected, but I can not use it for embedded sql in rpgle as it then defaults to the SQE engine resulting in horrendous performance.
The SQL view, on the other hand had NULLs until I used IFNULL( MBRDESCR, ''). But now MBRDECSR is a VARCHAR. Which is unacceptable.
So how do I create a SQL join without NULLs and VARCHARs?
Requested Sample Code:
DDS:
JDFTVAL
R TRANSR JFILE(TRANSPF MBRPF)
J JOIN(1 2)
JFLD(MBRID MBRID)
*
TRANSID JREF(1)
MBRID JREF(1)
MBRNAME JREF(2)
MBRSURNME JREF(2)
*
K TRANSID
K MBRID
SQL:
CREATE VIEW TRANSV01 AS (
SELECT TRANSID ,
MBRID ,
CAST(IFNULL(MBRNAME , '') as Char(20)) ,
CAST(IFNULL(MBRSURNME, '') as Char(25))
FROM TRANSPF
--Member Name
LEFT OUTER JOIN MBRPF on MBRID = MBRID
) RCDFMT TRANSR;
Please note the following:
Example above is simplified
Not every MBRID in the TRANSPF has a corresponding entry in the MBRPF (ie. no referential constraint). Thus when MBRPF is joined to the TRANSPF, there will be NULL values in MBRNAME, MBRSURNME. Unless JDFTVAL or IFNULL() is used.
I prefer not to have a VARCHAR, because of performance and extname() in rpgle.
I prefer not to have NULL values, I do not want the pgm to have to handle them.
Assuming it's the 'Allows the null value' that you find undesirable, use a UNION. The first SELECT chooses all the rows that match, which will set the NOT NULL property for you. The second SELECT chooses all the rows that don't have a match - you provide filler fields for those.
CREATE VIEW TRANSV01 AS (
SELECT TRANSID ,
MBRID ,
MBRNAME ,
MBRSURNME
FROM TRANSPF
--Member Name
JOIN MBRPF on MBRID = MBRID
UNION
SELECT TRANSID ,
MBRID ,
CAST('') as Char(20)) ,
CAST('') as Char(25))
FROM TRANSPF
--Member Name
EXCEPTION JOIN MBRPF on MBRID = MBRID
) RCDFMT TRANSR;
I am developing a TSQL stored proc using SSMS 2008 and am receiving the above error while generating a CTE. I want to add logic to this SP to return every day, not just the days with data. How do I do this? Here is my SP so far:
ALTER Proc [dbo].[rpt_rd_CensusWithChart]
#program uniqueidentifier = NULL,
#office uniqueidentifier = NULL
AS
DECLARE #a_date datetime
SET #a_date = case when MONTH(GETDATE()) >= 7 THEN '7/1/' + CAST(YEAR(GETDATE()) AS VARCHAR(30))
ELSE '7/1/' + CAST(YEAR(GETDATE())-1 AS VARCHAR(30)) END
if exists (
select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o.id = object_id(N'tempdb..#ENROLLEES')
) DROP TABLE #ENROLLEES;
if exists (
select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o.id = object_id(N'tempdb..#DISCHARGES')
) DROP TABLE #DISCHARGES;
declare #sum_enrollment int
set #sum_enrollment =
(select sum(1)
from enrollment_view A
join enrollment_info_expanded_view C on A.enrollment_id = C.enroll_el_id
where
(#office is NULL OR A.group_profile_id = #office)
AND (#program is NULL OR A.program_info_id = #program)
and (C.pe_end_date IS NULL OR C.pe_end_date > #a_date)
AND C.pe_start_date IS NOT NULL and C.pe_start_date < #a_date)
select
A.program_info_id as [Program code],
A.[program_name],
A.profile_name as Facility,
A.group_profile_id as Facility_code,
A.people_id,
1 as enrollment_id,
C.pe_start_date,
C.pe_end_date,
LEFT(datename(month,(C.pe_start_date)),3) as a_month,
day(C.pe_start_date) as a_day,
#sum_enrollment as sum_enrollment
into #ENROLLEES
from enrollment_view A
join enrollment_info_expanded_view C on A.enrollment_id = C.enroll_el_id
where
(#office is NULL OR A.group_profile_id = #office)
AND (#program is NULL OR A.program_info_id = #program)
and (C.pe_end_date IS NULL OR C.pe_end_date > #a_date)
AND C.pe_start_date IS NOT NULL and C.pe_start_date >= #a_date
;WITH #ENROLLEES AS (
SELECT '7/1/11' AS dt
UNION ALL
SELECT DATEADD(d, 1, pe_start_date) as dt
FROM #ENROLLEES s
WHERE DATEADD(d, 1, pe_start_date) <= '12/1/11')
The most obvious issue (and probably the one that causes the error message too) is the absence of the actual statement to which the last CTE is supposed to pertain. I presume it should be a SELECT statement, one that would combine the result set of the CTE with the data from the #ENROLLEES table.
And that's where another issue emerges.
You see, apart from the fact that a name that starts with a single # is hardly advisable for anything that is not a local temporary table (a CTE is not a table indeed), you've also chosen for your CTE a particular name that already belongs to an existing table (more precisely, to the already mentioned #ENROLLEES temporary table), and the one you are going to pull data from too. You should definitely not use an existing table's name for a CTE, or you will not be able to join it with the CTE due to the name conflict.
It also appears that, based on its code, the last CTE represents an unfinished implementation of the logic you say you want to add to the SP. I can suggest some idea, but before I go on I'd like you to realise that there are actually two different requests in your post. One is about finding the cause of the error message, the other is about code for a new logic. Generally you are probably better off separating such requests into distinct questions, and so you might be in this case as well.
Anyway, here's my suggestion:
build a complete list of dates you want to be accounted for in the result set (that's what the CTE will be used for);
left-join that list with the #ENROLLEES table to pick data for the existing dates and some defaults or NULLs for the non-existing ones.
It might be implemented like this:
… /* all your code up until the last WITH */
;
WITH cte AS (
SELECT CAST('7/1/11' AS date) AS dt
UNION ALL
SELECT DATEADD(d, 1, dt) as dt
FROM cte
WHERE dt < '12/1/11'
)
SELECT
cte.dt,
tmp.[Program code],
tmp.[program_name],
… /* other columns as necessary; you might also consider
enveloping some or all of the "tmp" columns in ISNULLs,
like in
ISNULL(tmp.[Program code], '(none)') AS [Program code]
to provide default values for absent data */
FROM cte
LEFT JOIN #ENROLLEES tmp ON cte.dt = tmp.pe_start_date
;
