I am having three tables viz. Bids(bid_id,base_price),Customer(customer_id,name,..) and Customer_Bid(customer_id,bid_id,bidding_amount) where customer bids and his bidded amount is stored in Customer_Bid table.
I want to show the details of customer along with his bidded id and the one with highest bid for same bid id.
I have tried to get the customer details but i am not able to show his bidded amount along with the highest bidded amount whish resides in same table.
Plz any one can help me out.
Thanks.
Edit This is the query that was in the comment
select cb.bid_id, c.customer_id ,MyBid=cb.total_bidding_ammount
, HighestBid= max(cb.total_bidding_ammount)
from customer as c
,customer_bidding as cb
,bid as b
group by cb.bid_id, c.customer_id, cb.total_bidding_ammount
If you change this:
, HighestBid= max(cb.total_bidding_ammount)
to something like this:
, HighestBid =
(select max(bidding_ammount)
from customer_bidding
where bid_id = bid.bid_id)
You will on the right track.
Try this one:
SELECT cb.bid_id,
c.customer_id,
cb.total_bidding_ammount,
topbids.customer_id as topbid_customer_id,
topbid
FROM customer c
INNER JOIN customer_bidding as cb
ON c.customer_id = cb.customer_id
INNER JOIN (
SELECT cb.bid_id, c.customer_id, MAX(cb.total_bidding_ammount) as topbid
FROM customer c
INNER JOIN customer_bidding cb
ON (c.customer_id = cb.customer_id)
GROUP BY cb.bid_id
) topbids
ON cb.bid_id = topbids.bid_id
select a.*, b.bidding_amount,
e.bidding_amount as highest_bid
from customer a
inner join customer_bid b on a.customer_id = b.customer_id
inner join bids c on b.bid_id = c.bid_id
join
(select * from (
select bidding_amount,bid_id
from customer_bid
order by bidding_amount desc
) d group by d.bid_id) e on b.bid_id = e.bid_id

I'm trying to get a list of ALL user roles for each user through the nopcommerce database. i just need the Customer.Id, Customer.Username, Customer.Email and Customer.Role (some have multiple roles)
This is all jacked up.
SELECT Customer.Id, Customer.Username, Customer.Email, CustomerRole.Name
FROM ((Customer
INNER JOIN CustomerRole ON CustomerRole.Id = Customer.Id)
INNER JOIN Customer_CustomerRole_Mapping ON Customer_CustomerRole_Mapping.CustomerRole_Id = CustomerRole.Id)
Any help is greatly appreciated!
I think you need a LEFT OTUER JOIN because in your DB can be user without role; in this case you can use this:
SELECT DISTINCT CUST.Id, CUST.Username, CUST.Email, CR.Id, CR.Name,
CCRM.CustomerRole_Id ,
FROM CUSTOMER CUST
LEFT OUTER JOIN Customer_CustomerRole_Mapping CCRM
ON CUST.ID = CCRM.Customer_Id
LEFT OUTER JOIN CustomerRole CR
ON CCRM.CustomerRole_Id = CR.Id
Also, you can have only one row per user with a column with his roles, like this:
SELECT DISTINCT CUST.Id, CUST.Username, CUST.Email,
Roles = STUFF((
SELECT ',' + CAST(CR1.Name as varchar(4000))
FROM CustomerRole CR1
LEFT OUTER JOIN Customer_CustomerRole_Mapping CCRM1
ON CCRM1.CustomerRole_Id = CR1.Id
LEFT OUTER JOIN CUSTOMER CUST1
ON CUST1.ID = CCRM1.Customer_Id
WHERE CUST1.Id = CUST.Id
FOR XML PATH('')
), 1, 1, '')
FROM CUSTOMER CUST
LEFT OUTER JOIN Customer_CustomerRole_Mapping CCRM
ON CUST.ID = CCRM.Customer_Id
LEFT OUTER JOIN CustomerRole CR
ON CCRM.CustomerRole_Id = CR.Id
Depending of your using, last query can be a little bit slow if you have a lot of customers.
I have three tables that I would like to select from
Table 1 has a bunch of static information about a user like their idnumber, name, registration date
Table 2 has the idnumber of the user, course number, and the date they registered for the course
Table 3 has the course number, and the title of the course
I am trying to use one query that will select the columns mentioned in table 1, with the most recent course they registered (name and date registered) as well as their first course registered (name and date registered)
Here is what I came up with
SELECT u.idst, u.userid, u.firstname, u.lastname, u.email, u.register_date,
MIN(l.date_inscr) as mindate, MAX(l.date_inscr) as maxdate, lc.coursename
FROM table1 u,table3 lc
LEFT JOIN table2 l
ON l.idCourse = lc.idCourse
WHERE u.idst = 12787
AND u.idst = l.idUser
And this gives me everything i need, and the dates are correct but I have no idea how to display BOTH of the names of courses. The most recent and the first.
And help would be great.
Thanks!!!
You can get your desired results by generating the min/max date_inscr for each user in a derived table and then joining that twice to table2 and table3, once to get each course name:
SELECT u.idst, u.userid, u.firstname, u.lastname, u.email, u.register_date,
l.mindate, lc1.coursename as first_course,
l.maxdate, lc2.coursename as latest_course
FROM table1 u
LEFT JOIN (SELECT idUser, MIN(date_inscr) AS mindate, MAX(date_inscr) AS maxdate
FROM table2
WHERE idUser = 12787
) l ON l.idUser = u.idst
LEFT JOIN table2 l1 ON l1.idUser = l.idUser AND l1.date_inscr = l.mindate
LEFT JOIN table3 lc1 ON lc1.idCourse = l1.idCourse
LEFT JOIN table2 l2 ON l2.idUser = l.idUser AND l2.date_inscr = l.maxdate
LEFT JOIN table3 lc2 ON lc2.idCourse = l2.idCourse
As #BillKarwin pointed out, this is more easily done using two separate queries.
Please see the tables:
Sub-Query Method:
select p.Name from Person p where p.PID in
(select mc.PID from M_Cast mc where mc.MID in
(select m.MID from Movie m where lower(title)='anand' ))
Even join is not working:
select p.Name
from Movie m
join M_Cast mc on m.MID = mc.MID
join Person p on mc.PID = p.PID
group by m.MID
having lower(m.title)='anand'
Your first query works without errors and if you make adjustments like in my few next steps the second one will work also.
Your second query: you can not select only p.Name and group by only m.MID. If it is in select clause and is not a part of aggregate function then you have to use it in group by clause. For example like this:
select p.Name
from Movie m
join M_Cast mc on m.MID = mc.MID
join Person p on mc.PID = p.PID
group by p.Name;
Your second query also has a HAVING clause having lower(m.title)='anand' but it should be in where clause like this:
select p.Name
from Movie m
join M_Cast mc on m.MID = mc.MID
join Person p on mc.PID = p.PID
where lower(m.title)='anand'
group by p.Name;
Now that both query are working you need to check if you have a movie with title 'ANAND' in your data. Also you need to check if you have a corresponding MID and PID data in other tables.
I have tested this in MySQL but it will maybe help you even if you use other database to guide you through some mistakes... Here is a small DEMO in MySQL where you will see that data will not be returned if there is no data in one table.
Here is a small DEMO for SQLite where you can see that your first query is working:
http://sqlfiddle.com/#!7/3ec44/1
and here is a small DEMO where you can see that my code is working:
http://sqlfiddle.com/#!7/3ec44/2
Please check the data!
After I have exchanged few comments with OP I have noticed that maybe it is a blank space in data making a problem. So I suggested this:
select p.Name
from Person p
where trim(p.PID, ' ') in (select trim(mc.PID, ' ')
from M_Cast mc
where mc.MID in (select m.MID
from Movie m
where lower(title)='anand'))
This also can be implemented in the second query:
select p.Name
from Movie m
join M_Cast mc on m.MID = mc.MID
join Person p on trim(mc.PID, ' ') = trim(p.PID, ' ')
where lower(m.title)='anand'
group by p.Name;
The problem was that in the query two tables were joined with mc.PID = p.PID and one column had data with blank spaces. So the query was trying to join this data : ' 1' = '1'. TRIM function will remove all the blank spaces in the value and join will then be possible.
SELECT MOVIE.title, person.name
FROM (MOVIE INNER JOIN mcast ON MOVIE.MID = mcast.MID) INNER JOIN person ON mcast.PID = person.PID
WHERE (((MOVIE.title)="ANAND"));
select distinct p.name [Actors in Anand]
Movie m
join M_Cast mc on mc.MID=m.MID
join Person p on p.PID=mc.PID
where m.title="Anand"
order by p.name
I have 3 Data Table Claim, Part and Labor.
In this Claim is parent table and Part and Labor is mapping tables of Claim and they have Part and Labor has the ClaimId as a Foreign Key.
Claim has data like:
Part has data Like
Labor table has data Like

Can anyone help me to achieve this in SQL server.
I have tried to solve with the Union/CTE but it did not gives the result as I want.
I got the same output (for your updated output screen) for this specific case. I don't know if any other data will work for you.
SELECT TMP.ClaimId
, CASE WHEN TMP.RowNum = 1 THEN TMP.Name ELSE NULL END AS ClaimName
, CASE WHEN TMP.RowNum = 1 THEN TMP.Note ELSE NULL END AS Note
, TMP.PartId
, TMP.PartNumber
, TMP.PartCost
, JOIN_L.LaborId
, JOIN_L.LaborCost
FROM (
SELECT C.ClaimId, C.Name, C.Note, P.PartId, P.PartNumber, P.PartCost
, ROW_NUMBER() OVER(PARTITION BY C.ClaimId ORDER BY P.PartId) AS RowNum
FROM Claim AS C
LEFT JOIN Part AS P ON C.ClaimId = P.ClaimId
)AS TMP
LEFT JOIN (
SELECT *
, ROW_NUMBER() OVER(PARTITION BY L.ClaimId ORDER BY L.ClaimId) AS RowNum
FROM Labor AS L
) AS JOIN_L ON (TMP.ClaimId = JOIN_L.ClaimId AND TMP.RowNum = JOIN_L.RowNum)
ORDER BY TMP.ClaimId
Not sure why you tried CTE here
Select C.ClaimId,C.name,C.Note,P.PartId,P.PartNumber,P.PartCost,L.LabourId,L.LabourCost
From Claim C
Left Outer Join Part P On P.ClaimId = C.ClaimId
Left Outer Join Labor L On L.ClaimId=C.ClaimId
I am trying to do a count inside a nested statement with inner join
select a.app_id, a.first_name, a.last_name, d.svd_id
from wwhs_app a inner join
wwhs_svc d on a.app_id = d.app_id
where a.app_id in(
select top 50 app_id
from wwhs_app
Where app_create_dt > '2012-07-23 00:00:00')
I need a count of svd_id as well, but I keep getting errors every way I try. Suggestions?
You need to count for svd_id but it's not in the query.
Did you mean 'app_id'?
Try this...
SELECT a.app_id, a.first_name, a.last_name, d.svd_id
FROM wwhs_app a
INNER JOIN wwhs_svc d on a.app_id = d.app_id
WHERE a.app_id in (
SELECT TOP 50 app_id, COUNT(*) as id_count
FROM wwhs_app
WHERE app_create_dt > '2012-07-23 00:00:00'
GROUP BY app_id ORDER BY id_count)
