Here's the code:
SELECT RD.INTREQDQUANTITY, I.strItemName, v.strVendName, iu.strItemUnitName,
ip.dblItemPAmount, MAX(ip.dtmItemPasOf) AS EXR
FROM TBLREQUESTDETAILS RD,tblitem I,tblvendor v,tblitemunit iu,tblitemprice ip`
WHERE RD.strReqDItemCode = I.strItemCode
AND RD.strReqDItemUnitCode = iu.strItemUnitCode
AND RD.strReqDVendCode = v.strVendCode
AND i.strItemCode = ip.strItemPItemCode
and RD.strReqDReqHCode = 'RQST121'
GROUP BY RD.INTREQDQUANTITY,I.strItemName,v.strVendName,iu.strItemUnitName, ip.dblItemPAmount
ORDER BY EXR desc ;
AND Here's The result:
What should I do If I want to fetch the current price for each itemname,vendorname and itemunit?? I want to fetch only those rows who's price is the Latest... Help me please those with boxes are the rows that i want to fetch
You can use where in the grouped value (and use explicict join notatio)
SELECT RD.INTREQDQUANTITY, I.strItemName, v.strVendName, iu.strItemUnitName,
ip.dblItemPAmount, ip.dtmItemPasOf AS EXR
FROM TBLREQUESTDETAILS RD
INNER JOIN tblitem I ON RD.strReqDItemCode = I.strItemCode
INNER JOIN tblvendor v ON D.strReqDVendCode = v.strVendCode
INNER JOIN tblitemunit iu ON RD.strReqDItemUnitCode = iu.strItemUnitCode
INNER JOIN tblitemprice ip ON i.strItemCode = ip.strItemPItemCode
WHERE RD.strReqDReqHCode = 'RQST121'
and ( RD.INTREQDQUANTITY, I.strItemName, v.strVendName, iu.strItemUnitName, ip.dtmItemPasOf)
in ( SELECT RD.INTREQDQUANTITY, I.strItemName, v.strVendName, iu.strItemUnitName,
MAX(ip.dtmItemPasOf)
FROM TBLREQUESTDETAILS RD
INNER JOIN tblitem I ON RD.strReqDItemCode = I.strItemCode
INNER JOIN tblvendor v ON D.strReqDVendCode = v.strVendCode
INNER JOIN tblitemunit iu ON RD.strReqDItemUnitCode = iu.strItemUnitCode
INNER JOIN tblitemprice ip ON i.strItemCode = ip.strItemPItemCode
WHERE RD.strReqDReqHCode = 'RQST121'
GROUP BY RD.INTREQDQUANTITY,I.strItemName,v.strVendName,iu.strItemUnitName
)
ORDER BY EXR desc ;
(and use explicict join notation .. i think is more readable)
I have a question.
This is my query:
SELECT
branches.naam as branche_naam,
subbranches.naam as subbranche_naam,
specialiteiten.naam as specialiteiten_naam
FROM bedrijfgegevens
INNER JOIN subbranches on subbranches.id = company.subbranche_id
INNER JOIN branches on branches.id = subbranches.branche_id
INNER JOIN bedrijfgegevens_specialiteiten on bedrijfgegevens_specialiteiten.bedrijfgegevens_id = bedrijfgegevens.id
INNER JOIN specialiteiten on specialiteiten.id = bedrijfgegevens_specialiteiten.specialiteiten_id
WHERE bedrijfgegevens.id in
(SELECT
bedrijfgegevens.id FROM bedrijfgegevens
INNER JOIN subbranches on subbranches.id = bedrijfgegevens.subbranche_id
INNER JOIN branches on branches.id = subbranches.branche_id
INNER JOIN bedrijfgegevens_specialiteiten on bedrijfgegevens_specialiteiten.bedrijfgegevens_id = bedrijfgegevens.id
INNER JOIN specialiteiten on specialiteiten.id = bedrijfgegevens_specialiteiten.specialiteiten_id
WHERE branches.naam = "test"
AND subbranches.naam = "demo"
AND specialiteiten.naam = "bla")
I think it's way to long and I am using the same tables.
What it does is:
subquery: get the company id where "specialiteiten.naam" = "bla".
query: get the other "specialiteiten" from that "bedrijf"
One method is to use a view.
If you want the values in a single delimited list, you can use group_concat():
SELECT bedrijfgegevens.id,
GROUP_CONCAT(CONCAT_WS(':', branches.naam, subbranches.naam, specialiteiten.naam))
FROM bedrijfgegevens INNER JOIN
subbranches
on subbranches.id = company.subbranche_id INNER JOIN
branches
on branches.id = subbranches.branche_id INNER JOIN
bedrijfgegevens_specialiteiten
on bedrijfgegevens_specialiteiten.bedrijfgegevens_id = bedrijfgegevens.id INNER JOIN
specialiteiten
on specialiteiten.id = bedrijfgegevens_specialiteiten.specialiteiten_id
GROUP BY bedrijfgegevens.id
HAVING SUM(branches.naam = 'test' AND subbranches.naam = 'demo' AND specialiteiten.naam = 'bla') > 0;
I have the following query and would like to convert it to using a left outer join instead of a not in to see if it would run faster that way. It's currently taking this query about 40 seconds to run on our database. I'm not familiar enough with using outer joins for this type of thing to convert it myself.

c.contact_id as contact_id,
c.orgid as organization_id,

inner join cnx_address as a on c.home_address_uid = a.address_uid
where a.address_state = 'OH'
and (c.orgid = 45 or c.orgid = 55)
and c.contact_id NOT IN (

Please am having difficulty in optimizing this query. What am trying to achieve is to join about 8 tables, of which only about 3 of the tables contains large data (1.5m records). This query returns expected records but is taking 1min to run which is bad.
I know it can be optimized to perform far better, pls i need assistance from you experts. I have index on the fields used for join already.

I've got the query below that's pulling data from a number of tables to create an update:
UPDATE en_inter.subscribers_data AS sd
inner join en_inter.list_subscribers AS ls on sd.subscriberid = ls.subscriberid
LEFT JOIN (
SELECT pd1.email_address,COUNT(pd1.email_address) AS NumDowns
FROM email.papr_down pd1
INNER JOIN email.papr_data pd2 on pd1.paper_id = pd2.id
INNER JOIN email.papr_subj ps on ps.id = pd2.subject
INNER JOIN email.papr_exam pe on pe.id = pd2.exam
INNER JOIN email.papr_levl pl on pl.id = pd2.level
WHERE pd2.exam = 1
and pd2.level = 4
GROUP BY email_address
) AS downs ON downs.email_address = ls.emailaddress
SET sd.data = ifnull(downs.NumDowns,1)
WHERE sd.fieldid = 33;
It works fine but when there are plenty of records in papr_down then it takes ages to process. Any ideas about how it can be optimized?
What I think is the join between the emailAddress is the issue here, you can try out with the join with the Id's.
If you provide us the screen shot of the below query ::
EXPLAIN Select * from
en_inter.subscribers_data AS sd
inner join en_inter.list_subscribers AS ls on sd.subscriberid = ls.subscriberid
LEFT JOIN (
SELECT pd1.email_address,COUNT(pd1.email_address) AS NumDowns
FROM email.papr_down pd1
INNER JOIN email.papr_data pd2 on pd1.paper_id = pd2.id
INNER JOIN email.papr_subj ps on ps.id = pd2.subject
INNER JOIN email.papr_exam pe on pe.id = pd2.exam
INNER JOIN email.papr_levl pl on pl.id = pd2.level
WHERE pd2.exam = 1
and pd2.level = 4
GROUP BY email_address
) AS downs ON downs.email_address = ls.emailaddress
WHERE sd.fieldid = 33
As I know we should use joins only for the columns which are preset in SELECT clause and for other joins we should implement using WHERE clause
Please try following query:
UPDATE en_inter.subscribers_data AS sd
inner join en_inter.list_subscribers AS ls
on sd.subscriberid = ls.subscriberid
LEFT JOIN (
SELECT pd1.email_address,COUNT(pd1.email_address) AS NumDowns
FROM email.papr_down AS pd1
INNER JOIN email.papr_data AS pd2 on pd1.paper_id = pd2.id
WHERE
email.papr_exam.id in (select exam from email.papr_data where exam = 1)
AND
email.papr_levl.id in (select level from email.papr_data where level = 4 )
AND
email.papr_subj.id in (select subject from email.papr_data)
GROUP BY email_address
) AS downs ON downs.email_address = ls.emailaddress
SET sd.data = ifnull(downs.NumDowns,1)
WHERE sd.fieldid = 33;
