I want to use join instead subquery to find the trade id not exist on trade_log filtered by ip and current date for mysql syntax below.
SELECT plug.id as a,
plug.url as b,
trade.id as c
FROM plug, trade
WHERE trade.id = plug.trade_id
AND trade.id NOT IN (SELECT trade_log.trade_id
FROM trade_log
WHERE trade_log.ip = '".$ip."'
AND trade_log.log_date = CURDATE())
AND trade.status = 1
AND plug.status = 1
ORDER BY plug.weight DESC
LIMIT 1
Please help me...
Use:
SELECT p.id as a,
p.url as b,
t.id as c
FROM PLUG p
JOIN TRADE t ON t.id = p.trade_id
AND t.status = 1
LEFT JOIN TRADE_LOG tl ON tl.trade_id = t.id
AND tl.ip = mysql_real_escape_string($ip)
AND tl.log_date = CURDATE()
WHERE p.status = 1
AND tl.ip IS NULL
ORDER BY p.weight DESC
LIMIT 1
Same as OMG Ponies:
SELECT p.id as a,
p.url as b,
t.id as c
FROM plug p
INNER JOIN trade t ON (t.id = p.trade_id AND t.status = 1)
LEFT JOIN trade_log l ON (l.trade_id = t.id AND l.ip = '".$ip."' AND l.log_date = CURDATE())
WHERE p.status = 1 AND l.trade_id IS NULL
ORDER BY p.weight DESC
LIMIT 1

I'm making a query to get the stages of a case. So Now I have three cases with 3 stages (the last stage inserted in the table user_case_stage).
SELECT DISTINCT ON (c.id)
c.id,
f.name
FROM schema.user a
JOIN schema.intern_user b ON a.id = b."userId"
JOIN schema.user_case c ON b.id = c."internUserId"
JOIN schema.user_case_stage d ON c.id = d."userCaseId"
JOIN schema.stage f ON d."stageId" = f.id
WHERE b.id = 1
ORDER BY c.id,d."createdAt" DESC
Result:
caseId stageName
1 "Pasive"
6 "Closed"
7 "Closed"
But I want something to count by stageName like this:
total stageName
1 "Pasive"
2 "Closed"
assumed your logic is correct , since you didn't provide any information, here is how you can do it:
SELECT
f.name
, count(distinct c.id) total
FROM schema.user a
JOIN schema.intern_user b ON a.id = b."userId"
JOIN schema.user_case c ON b.id = c."internUserId"
JOIN schema.user_case_stage d ON c.id = d."userCaseId"
JOIN schema.stage f ON d."stageId" = f.id
WHERE b.id = 1
group by f.name
Is there a way to multiply an aggregate function? I need to multiply SUM(ma.gewight) for every article (an article is, for example, H114972 which is iron and is 32,1 meters) so the GROUP BY groups all same articles and for every different article I need to multiply a different number (the column that I am using to multiply is e.best_wert which is the meters, mentioned above). So basically I need to multiply the SUM(ma.gewicht) with e.best_wert - but it doesn't work.
PS. Gewicht = weight
PSS. e.best_wert = weight value/meters
SELECT m.artikel, COUNT(ei.bestell_po) bestell_po_menge, SUM(ma.gewicht) AS summe_gewicht--, SUM(e.best_wert*ma.gewicht) AS summe_kg
FROM MATV030 m
INNER JOIN EINV030 e ON e.BESTELL_NR = m.BESTELL_NR
INNER JOIN EINV035 ei ON e.bestell_nr = ei.bestell_nr
INNER JOIN MATV010 ma ON m.ARTIKEL = ma.ARTIKEL
WHERE e.lieferant = '6000176' AND m.menge_buch <> 0
--AND m.artikel = 'H114972'
AND m.bs = 'WE' AND m.budatum >= '20190101' AND m.budatum < '20190201'
GROUP BY m.artikel, ma.gewicht
ORDER BY m.artikel ASC
Try like this
SELECT m.artikel, COUNT(ei.bestell_po) bestell_po_menge, SUM(ma.gewicht) AS summe_gewicht, (e.best_wert * SUM(ma.gewicht)) AS summe_kg
FROM MATV030 m
INNER JOIN EINV030 e ON e.BESTELL_NR = m.BESTELL_NR
INNER JOIN EINV035 ei ON e.bestell_nr = ei.bestell_nr
INNER JOIN MATV010 ma ON m.ARTIKEL = ma.ARTIKEL
WHERE e.lieferant = '6000176' AND m.menge_buch <> 0
--AND m.artikel = 'H114972'
AND m.bs = 'WE' AND m.budatum >= '20190101' AND m.budatum < '20190201'
GROUP BY m.artikel, e.best_wert
ORDER BY m.artikel ASC
Try this,
;With CTE as
(
SELECT ma.ARTIKEL, SUM(ma.gewicht) AS summe_gewicht--, SUM(e.best_wert*ma.gewicht) AS summe_kg
FROM MATV030 m
INNER JOIN MATV010 ma ON m.ARTIKEL = ma.ARTIKEL
WHERE m.menge_buch > 0
--AND m.artikel = 'H114972'
AND m.bs = 'WE' AND m.budatum >= '20190101' AND m.budatum < '20190201'
GROUP BY m.ARTIKEL
--ORDER BY m.artikel ASC
)
SELECT m.artikel, COUNT(ei.bestell_po) bestell_po_menge,summe_gewicht, summe_gewicht*e.best_wert AS summe_kg
FROM CTE C
inner join MATV030 m on m.artikel=c.artikel
INNER JOIN EINV030 e ON e.BESTELL_NR = m.BESTELL_NR
INNER JOIN EINV035 ei ON e.bestell_nr = ei.bestell_nr
WHERE e.lieferant = '6000176'
GROUP BY m.artikel
ORDER BY m.artikel ASC
You can create A CTE (Common Table Expression) table with your aggregate values and then multiply both the tables using CTE.
I need help to return a result if value exists or no.
UPDATED: The image show where I need help:
You can do it using CASE EXPRESSION with a LEFT JOIN .
I didn't fully understand the output you expect, but just add the columns you want:
#in_myvar = 11
select bt.username,at.postid,
CASE WHEN ct.userid is null the 0 else 1 end as c_ind
from A at
INNER JOIN B bt
ON (at.userid = bt.userid and bt.userid = #in_myvar)
LEFT JOIN C ct
ON(ct.userid = at.userid)
Use this query:
declare #in_myvar int = 11
select B.username,A.postid,(Case when C.postid = A.postid then 1 Else 0 end) as UserExists
from A inner join B on A.userID = B.UserID
Left Join C
On C.userID = A.userID
where B.userID = #in_myvar
You want a result row for each record in A. So select from A. The data from the other tables can be got with subqueries:
select
(select username from b where b.userid = a.userid) as username,
a.postid,
case when exists (select * from c where c.userid = a.userid) then 1 else 0 end as has_c
from a;
As B:A = 1:n, you can also join B, if you like that better:
select
b.username,
a.postid,
case when exists (select * from c where c.userid = a.userid) then 1 else 0 end as has_c
from a
join b on b.userid = a.userid;
I have a query get_product:
select A.product_id,
A.name, A.description, A.type_id,
B.series_name
product_data A
inner join
series B
on A.series_raw_id = B.series_raw_id
where A.product_id = 503061
and A.registration_type_id = 4
order by B.series_name
and second query
select B.series_name,
A.TEMPACC_STATUS
FROM
ACCESS_FACT A
inner join
**get_product** B
on A.TEMPACC_PRODUCT_ID = B.product_id
where A.TEMPACC_DATE_ID between 6717 and 6808
and A.reason_id_total = 0
group by Series_name,
STATUS
In the second query we use data from first query (get_product is the first query). How do I get that table here?
You could use the WITH clause.
For example,
WITH get_product AS
(SELECT A.product_id,
A.name,
A.description,
A.type_id,
B.series_name product_data A
INNER JOIN series B
ON A.series_raw_id = B.series_raw_id
WHERE A.product_id = 503061
AND A.registration_type_id = 4
ORDER BY B.series_name
)
SELECT B.series_name,
A.TEMPACC_STATUS
FROM ACCESS_FACT A
INNER JOIN get_product B
ON A.TEMPACC_PRODUCT_ID = B.product_id
WHERE A.TEMPACC_DATE_ID BETWEEN 6717 AND 6808
AND A.reason_id_total = 0
GROUP BY Series_name,
STATUS;
Or, you could use an INLINE VIEW
SELECT B.series_name,
A.TEMPACC_STATUS
FROM ACCESS_FACT A
INNER JOIN
(SELECT A.product_id,
A.name,
A.description,
A.type_id,
B.series_name product_data A
INNER JOIN series B
ON A.series_raw_id = B.series_raw_id
WHERE A.product_id = 503061
AND A.registration_type_id = 4
ORDER BY B.series_name
) B ON A.TEMPACC_PRODUCT_ID = B.product_id
WHERE A.TEMPACC_DATE_ID BETWEEN 6717 AND 6808
AND A.reason_id_total = 0
GROUP BY Series_name,
STATUS;
I have to convert the correlated sub-query to non-correlated sub-query cuz of performance issues .
like that :
The correlated sub-query :(So slow ) returns 4000 row
SELECT a.personid,a.name,b.conid,d.condat,e.connam
FROM main_empr a INNER JOIN coninr b
ON a.personid = b.personid AND a.calc_year = b.calc_year
INNER JOIN mainconinr c
ON b.conid = c.conid
INNER JOIN coninr d
ON a.personid = d.personid AND a.calc_year = d.calc_year
INNER JOIN mainconinr e
ON d.conid = e.conid
WHERE c.active_flag = 1 and c.endreward_flag = 1
AND d.condat = (SELECT MIN(bb.condat) FROM coninr bb WHERE bb.personid = b.personid AND bb.calc_year = b.calc_year AND ((bb.conid > 0 AND bb.conid < 4 ) OR (bb.conid IN(16,6) )) )
AND b.condat = (SELECT MAX(bb.condat) FROM coninr bb WHERE bb.personid = b.personid AND bb.calc_year = b.calc_year AND ((bb.conid > 0 AND bb.conid < 4 ) OR (bb.conid IN(16,6) )) )
AND ( 0 = ( SELECT COUNT(*) FROM servmain x WHERE x.personid = a.personid AND x.calc_year = a.calc_year )
OR b.condat > ( SELECT MAX(x.serv_date) FROM servmain x WHERE x.personid = a.personid AND x.calc_year = a.calc_year ) )
AND a.calc_year = 2018
The non-correlated query :returns about 12300 rows!!
SELECT a.personid,a.name,b.conid,d.condat,e.connam
FROM main_empr a INNER JOIN
coninr b
ON a.personid = b.personid AND a.calc_year = b.calc_year
INNER JOIN mainconinr c
ON b.conid = c.conid
INNER JOIN coninr d
ON a.personid = d.personid AND a.calc_year = d.calc_year
INNER JOIN mainconinr e ON d.conid = e.conid
INNER JOIN
(SELECT MAX(bb.condat) AS condat ,bb.personid,bb.calc_year ,bb.conid
FROM coninr bb
GROUP BY bb.personid,bb.calc_year,bb.conid
)Max_cont
ON Max_cont.personid = b.personid AND Max_cont.calc_year = b.calc_year AND Max_cont.condat = b.condat AND ((Max_cont.conid > 0 AND Max_cont.conid < 4 ) OR (Max_cont.conid IN(16,6) ))
INNER JOIN
(SELECT MIN(dd.condat) AS condat ,dd.personid,dd.calc_year,dd.conid
FROM coninr dd GROUP BY dd.personid,dd.calc_year,dd.conid
)Min_cont
ON Min_cont.personid = d.personid AND Min_cont.calc_year = d.calc_year AND Min_cont.condat = d.condat AND ((Min_cont.conid > 0 AND Min_cont.conid < 4 ) OR (Min_cont.conid IN(16,6) ))
WHERE c.active_flag = 1 and c.endreward_flag = 1
AND ( 0 = ( SELECT COUNT(*) FROM servmain x WHERE x.personid = a.personid AND x.calc_year = a.calc_year )
OR b.condat > ( SELECT MAX(x.serv_date) FROM servmain x WHERE x.personid = a.personid AND x.calc_year = a.calc_year ) )
AND a.calc_year = 2018
The problem is :
I use the coninr table twice to get the last and the first contract date in the same row .
It works fine in the first query but it was so slow because of the correlated sub-query,but in the second query it brings more than one row for the same person one of them for the first contract date and the other for the last one !!
How to fix this problem ?
This looks reasonable, but I've no way to know how it'll perform:
SELECT a.personid,a.name,b.conid,d.condat,e.connam
FROM main_empr a INNER JOIN coninr b
ON a.personid = b.personid AND a.calc_year = b.calc_year
INNER JOIN mainconinr c
ON b.conid = c.conid
INNER JOIN coninr d
ON a.personid = d.personid AND a.calc_year = d.calc_year
INNER JOIN mainconinr e
ON d.conid = e.conid
inner join
(
SELECT bb.personid, bb.calc_year, bb.conid, MIN(bb.condat) MinDate, MAX(bb.condat) MaxDate
FROM coninr bb WHERE
where (bb.conid > 0 and bb.conid < 4) or (bb.conid in (6, 16))
group by bb.personid, bb.calc_year, bb.conid
) zz on d.concat = zz.MinDate and b.condat = zz.MaxDate and b.personid = zz.personid and b.calc_year = zz.calc_year
left outer join
(
select s.personid, s.calc_year, max(s.serv_date) MaxServDate
from servmain s
group by s.personid, s.calc_year
) s on a.personid = s.personid and a.calc_year = s.calc_year
WHERE c.active_flag = 1 and c.endreward_flag = 1
and (s.MaxServDate is null or b.condat ? s.MaxServDate
AND a.calc_year = 2018
You don't need two queries for table coninr, you can get min and max in the same query with the group by. Also, for ServMain, doing a left outer join and putting in the where that either it's null (equivalent to count(*) = 0) or is less than b.condat takes care of that.
