I m facing an issues in sql query
It worked with previous version - 5.6
But now its not working with version 5.7
So anyone can help me to convert this query to sql 5.7
SELECT to_startdate, to_enddate
FROM tour
WHERE to_name !=''
AND to_startdate !='0000-00-00'
AND to_deactivated !=1
GROUP BY MONTH(to_startdate), YEAR(to_startdate)
ORDER BY to_startdate
Your query doesn't make sense in general -- the select references columns and these are not aggregated. You can use aggregation functions. I don't know what values you want, but something like this:
SELECT MIN(to_startdate), MIN(to_enddate)
FROM tour
WHERE to_name <> '' AND
to_startdate <> '0000-00-00' AND
to_deactivated <> 1
GROUP BY MONTH(to_startdate), YEAR(to_startdate)
ORDER BY MIN(to_startdate)

I have Student_Table with following structure.
Student_Note Table
student_id seq_num note
11212 1 firstnote
11212 2 secondNote
11212 3 thirdNote
21232 1 secondstudentnote1
21232 2 secondstudentnote2
so on
I want to get latest note (which has largest seq_num) for a particilar student.
I have tried following query
select tn.note from Student_Note tn JOIN Student_Note tn1
ON (tn.student_id =tn1.student_id AND tn.seq_num < tn1.seq_num)
where tn.student_id=11212
it is giving more than one row. How to achieve aforementioned scenario ?
I forgot mention that I am using above query as subquery . As per sybase TOP clause will not work in subquery.
P.S. I am using sybase.
OK - changed as apparently cannot use TOP.........
select tn.note from Student_Note tn
where tn.student_id=11212
and tn.seq_num = (SELECT MAX(seq_num) from Student_Note WHERE Student_Note.Student_Id = tn.Student_Id)
Please try this
select substring(max(str(seq_num,10,'0') + note),11,len(note))
from Student_Note
where student_id=11212
I have the following query that works fine in firebird 2.1, however I cannot get it to work on a db with the exact same structure in 1.5
select c.printchecknumber, v.voidamount
from checks c
join (select checknumber, sum(voidamount) as voidamount
from checkitem
where voidtype =1
group by checknumber) v on c.checknumber = v.checknumber
order by c.printchecknumber
Any ideas?
The error message is
Invalid token
Dynamic SQL Error
SQL error code = -104
Token unknown - line 1, char 61
the error is at the start of the second select
I'm guessing that Firebird 1.5 doesn't support subqueries in the from clause. In any case, you can write this as a simpler query. The following should do what you want:
select c.printchecknumber, sum(voidamount) as voidamount
from checkitem ci join
checks c
on ci.checknumber = c.checknumber
where ci.voidtype =1
group by c.printchecknumber;
EDIT:
If you want to include checkid, then this might work:
select c.printchecknumber, c.checkid, sum(voidamount) as voidamount
from checkitem ci join
checks c
on ci.checknumber = c.checknumber
where ci.voidtype =1
group by c.printchecknumber, c.checkid;
I don't know why it does not work on an earlier system and I'd need to know the error message to help, but the following would work on any sql which supports the over() clause which I believe firebird does with 3.0
select c.printchecknumber,
sum(v.voidamount) over (partition by printchecknumber)
from checks c
join checkitem v on c.checknumber = v.checknumber and v.voidtype = 1
In the query
cr is customers,
chh? ise customer_pays,
cari_kod is customer code,
cari_unvan1 is customer name
cha_tarihi is date of pay,
cha_meblag is pay amount
The purpose of query, the get the specisified list of customers and their last date for pay and amount of money...
Actually my manager needs more details but the query is very slow and that is why im using only 3 subquery.
The question is how to combine them ?
I have researched about Cte and "with clause" and "subquery in "where " but without luck.
Can anybody have a proposal.
Operating system is win2003 and sql server version is mssql 2005.
Regards
select cr.cari_kod,cr.cari_unvan1, cr.cari_temsilci_kodu,
(select top 1
chh1.cha_tarihi
from dbo.CARI_HESAP_HAREKETLERI chh1 where chh1.cha_kod=cr.cari_kod order by chh1.cha_RECno) as sontar,
(select top 1
chh2.cha_meblag
from dbo.CARI_HESAP_HAREKETLERI chh2 where chh2.cha_kod=cr.cari_kod order by chh2.cha_RECno) as sontutar
from dbo.CARI_HESAPLAR cr
where (select top 1
chh3.cha_tarihi
from dbo.CARI_HESAP_HAREKETLERI chh3 where chh3.cha_kod=cr.cari_kod order by chh3.cha_RECno) >'20130314'
and
cr.cari_bolge_kodu='322'
or
cr.cari_bolge_kodu='324'
order by cr.cari_kod
You will probably speed up the query by changing your last where clause to:
where (select top 1 chh3.cha_tarihi
from dbo.CARI_HESAP_HAREKETLERI chh3 where chh3.cha_kod=cr.cari_kod
order by chh3.cha_RECno
) >'20130314' and
cr.cari_bolge_kodu in ('322', '324')
order by cr.cari_kod
Assuming that you want both the date condition met and one of the two codes. Your original logic is the (date and code = 322) OR (code = 324).
The overall query can be improved by finding the record in the chh table and then just using that. For this, you want to use the window function row_number(). I think this is the query that you want:
select cari_kod, cari_unvan1, cari_temsilci_kodu,
cha_tarihi, cha_meblag
from (select cr.*, chh.*,
ROW_NUMBER() over (partition by chh.cha_kod order by chh.cha_recno) as seqnum
from dbo.CARI_HESAPLAR cr join
dbo.CARI_HESAP_HAREKETLERI chh
on chh.cha_kod=cr.cari_kod
where cr.cari_bolge_kodu in ('322', '324')
) t
where chh3.cha_tarihi > '20130314' and seqnum = 1
order by cr.cari_kod;
This version assumes the revised logic date/code logic.
The inner subquery select might generate an error if there are two columns with the same name in both tables. If so, then just list the columns instead of using *.
I have a query which should work, but it seems I am a victim of a poor database technology. I need to run the query below on a Pervasive SQL database. The manufacturer of the product using Pervasive tells me the version they are using is 10 which should support subqueries, but I have yet to be able to run even a simple subquery. So, I am wondering if the following query can be rewritten to eliminate the subquery:
SELECT
OuterTime.Employee,
OuterTime.Date,
OuterTime.Pay_ID,
OuterTime.Description,
OuterTime.Equipment,
OuterTime.JC_Cost_Code,
OuterTime.JC_Category,
OuterTime.Units,
(
SELECT
SUM(SubQueryTime.Units)
FROM
PRT_NEW__TIME AS SubQueryTime
WHERE
SubQueryTime.Employee = OuterTime.Employee
GROUP BY
SubQueryTime.Employee
) AS TotalHoursForEmp
FROM
PRT_NEW__TIME AS OuterTime
In standard SQL you can do this, though I have no idea about PervasiveSQL specifically...
SELECT
OuterTime.Employee,
OuterTime.Date,
OuterTime.Pay_ID,
OuterTime.Description,
OuterTime.Equipment,
OuterTime.JC_Cost_Code,
OuterTime.JC_Category,
OuterTime.Units,
COALESCE(TotalHoursForEmp.TotalUnits, 0) AS TotalUnits
FROM
PRT_NEW__TIME AS OuterTime
LEFT JOIN
(
SELECT
Employee,
SUM(Units) AS TotalUnits
FROM
PRT_NEW__TIME
GROUP BY
Employee
)
AS TotalHoursForEmp
ON TotalHoursForEmp.Employee = OuterTime.Employee
Not a Pervasive SQL guy, but would this work? Not sure it accomplishes your query goals:
SELECT
OuterTime.Employee,
OuterTime.Date,
OuterTime.Pay_ID,
OuterTime.Description,
OuterTime.Equipment,
OuterTime.JC_Cost_Code,
OuterTime.JC_Category,
SUM(OuterTime.Units) AS TotalHoursForEmp
GROUP BY OuterTime.Employee, OuterTime.Date, OuterTime.Pay_ID,
OuterTime.Description, OuterTime.Equipment, OuterTime.JC_Cost_Code,
OuterTime.JC_Category
FROM
PRT_NEW__TIME AS OuterTime
So I decided to try out PostgreSQL instead of MySQL but I am having some slight conversion problems. This was a query of mine that samples data from four tables and spit them out all in on result.
I am at a loss of how to convey this in PostgreSQL and specifically in Django but I am leaving that for another quesiton so bonus points if you can Django-fy it but no worries if you just pure SQL it.
SELECT links.id, links.created, links.url, links.title, user.username, category.title, SUM(votes.karma_delta) AS karma, SUM(IF(votes.user_id = 1, votes.karma_delta, 0)) AS user_vote
FROM links
LEFT OUTER JOIN `users` `user` ON (`links`.`user_id`=`user`.`id`)
LEFT OUTER JOIN `categories` `category` ON (`links`.`category_id`=`category`.`id`)
LEFT OUTER JOIN `votes` `votes` ON (`votes`.`link_id`=`links`.`id`)
WHERE (links.id = votes.link_id)
GROUP BY votes.link_id
ORDER BY (SUM(votes.karma_delta) - 1) / POW((TIMESTAMPDIFF(HOUR, links.created, NOW()) + 2), 1.5) DESC
LIMIT 20
The IF in the select was where my first troubles began. Seems it's an IF true/false THEN stuff ELSE other stuff END IF yet I can't get the syntax right. I tried to use Navicat's SQL builder but it constantly wanted me to place everything I had selected into the GROUP BY and that I think it all kinds of wrong.
What I am looking for in summary is to make this MySQL query work in PostreSQL. Thank you.
Current Progress
Just want to thank everybody for their help. This is what I have so far:
SELECT links_link.id, links_link.created, links_link.url, links_link.title, links_category.title, SUM(links_vote.karma_delta) AS karma, SUM(CASE WHEN links_vote.user_id = 1 THEN links_vote.karma_delta ELSE 0 END) AS user_vote
FROM links_link
LEFT OUTER JOIN auth_user ON (links_link.user_id = auth_user.id)
LEFT OUTER JOIN links_category ON (links_link.category_id = links_category.id)
LEFT OUTER JOIN links_vote ON (links_vote.link_id = links_link.id)
WHERE (links_link.id = links_vote.link_id)
GROUP BY links_link.id, links_link.created, links_link.url, links_link.title, links_category.title
ORDER BY links_link.created DESC
LIMIT 20
I had to make some table name changes and I am still working on my ORDER BY so till then we're just gonna cop out. Thanks again!
Have a look at this link GROUP BY
When GROUP BY is present, it is not
valid for the SELECT list expressions
to refer to ungrouped columns except
within aggregate functions, since
there would be more than one possible
value to return for an ungrouped
column.
You need to include all the select columns in the group by that are not part of the aggregate functions.
A few things:
Drop the backticks
Use a CASE statement instead of IF() CASE WHEN votes.use_id = 1 THEN votes.karma_delta ELSE 0 END
Change your timestampdiff to DATE_TRUNC('hour', now()) - DATE_TRUNC('hour', links.created) (you will need to then count the number of hours in the resulting interval. It would be much easier to compare timestamps)
Fix your GROUP BY and ORDER BY
Try to replace the IF with a case;
SUM(CASE WHEN votes.user_id = 1 THEN votes.karma_delta ELSE 0 END)
You also have to explicitly name every column or calculated column you use in the GROUP BY clause.
