I'm querying a table (COURSEPLACE) to generate a result set of students. This contains a range of variables taken from the course table.
I then want to join an Addresses table (which contains multiple address records per student) but only append to the results the 1 postcode that was created on the same (or the closest) date to the date that the Student record was created.
What I've tried is the following, but this only gets me those records where the date value is an exact match - how do I extend this to (effectively) find and select the postcode value from the address record that has the closest date stamp to the student record date stamp?:
SELECT cp.CONTACTNO, cp.AGEONENTRY, cp.COURSETITLE, cp.FACULTY, ad.POSTCODE
FROM COURSEPLACE cp
LEFT OUTER JOIN ADDRESS ad ON ad.CONTACTNO=cp.CONTACTNO
WHERE
cp.TYPE = 'Application'
AND cp.TERM = '2015/6'
AND
(
ad.TYPE = 'Home' AND CONVERT(VARCHAR(23),ad.CREATIONDATE,103) = CONVERT(VARCHAR(23),cp.CREATIONDATE,103)
)
SELECT TOP 1
cp.CONTACTNO, cp.AGEONENTRY, cp.COURSETITLE, cp.FACULTY, ad.POSTCODE,
FROM
COURSEPLACE cp
INNER JOIN ADDRESS ad ON ad.CONTACTNO=cp.CONTACTNO
WHERE CP.TYPE = 'Application'
AND CP.TERM = '2016/5'
AND AD.TYPE = 'Home'
ORDER BY
DATEDIFF(AD.CREATIONDATE, CP.CREATIONDATE) ASC;
Solved it with OUTER APPLY, given as an answer to a previous question:
OUTER APPLY (SELECT TOP 1 * FROM ADDRESS ad2 WHERE ad2.CONTACTNO=cp.CONTACTNO ORDER BY DATEDIFF(dd,cp.CREATIONDATE,ad2.CREATIONDATE)) AD
Give this a whirl....
SELECT cp.CONTACTNO, cp.AGEONENTRY, cp.COURSETITLE, cp.FACULTY, ad.POSTCODE
FROM COURSEPLACE cp
LEFT JOIN ADDRESS ad ON
ad.CONTACTNO=cp.CONTACTNO
INNER JOIN
(SELECT CONTACTNO, MAX(CREATIONDATE) dt
FROM ADDRESS
WHERE CREATIONDATE <= cp.CREATIONDATE
GROUP BY CONTACTNO) ad2 on ad2.dt = ad.CREATIONDATE and ad2.CONTACTNO = ad.CONTACTNO
WHERE
cp.TYPE = 'Application'
AND cp.TERM = '2015/6'

based on my question above, below is the SQL
SELECT ets_tools.tools_id, ets_borrower.fullname, ets_team.team_name, ets_borrow.time_from,
ets_borrow.time_to, ets_borrow.borrow_id FROM ets_tools
INNER JOIN ets_tools_borrow ON ets_tools.tools_id = ets_tools_borrow.tools_id
INNER JOIN ets_borrow ON ets_borrow.borrow_id = ets_tools_borrow.borrow_id
INNER JOIN ets_borrower ON ets_borrower.badgeid = ets_borrow.badgeid
INNER JOIN ets_team ON ets_team.team_id = ets_borrower.team_id
WHERE ets_tools.borrow_id IS NOT NULL AND ets_borrow.status_id = 1 AND ets_borrow.time_to IS NULL
and the result display like this:
From the image above, we can see that the borrow_id with value 1 display two rows. Now, how to display only one borrow_id for value 1 since its duplicate the same things.
Anyone can help?
Assuming you want to retain the record having the smallest tools_id, you could aggregate by the other columns and take the MIN of tools_id:
SELECT
MIN(ets_tools.tools_id) AS tools_id,
ets_borrower.fullname,
ets_team.team_name,
ets_borrow.time_from,
ets_borrow.time_to,
ets_borrow.borrow_id
FROM ets_tools
INNER JOIN ets_tools_borrow ON ets_tools.tools_id = ets_tools_borrow.tools_id
INNER JOIN ets_borrow ON ets_borrow.borrow_id = ets_tools_borrow.borrow_id
INNER JOIN ets_borrower ON ets_borrower.badgeid = ets_borrow.badgeid
INNER JOIN ets_team ON ets_team.team_id = ets_borrower.team_id
WHERE
ets_tools.borrow_id IS NOT NULL AND
ets_borrow.status_id = 1 AND
ets_borrow.time_to IS NULL
GROUP BY
ets_borrower.fullname,
ets_team.team_name,
ets_borrow.time_from,
ets_borrow.time_to,
ets_borrow.borrow_id;
Try this:
Change the SELECT to SELECT TOP 1 WITH TIES
And at the end add ORDER BY ROW_NUMBER() OVER(PARTITION BY ets_borrow.borrow_id ORDER BY ets_tools.tools_id)
I have tried all possible joins and sub-queries but I cant get the data to only return one value from table 2 that exactly matches the vendor ID. If I dont have the address included in the query, I get one hit for the vendor ID. How can I make it so that when I add the address, I only want the one vendor that I get prior to adding the address.
The vendor from table one must be VEN-CLASS IS NOT NULL.
This was my last attempt using subquery:
SELECT DISTINCT APVENMAST.VENDOR_GROUP,
APVENMAST.VENDOR,
APVENMAST.VENDOR_VNAME,
APVENMAST.VENDOR_CONTCT,
APVENMAST.TAX_ID,
Subquery.ADDR1
FROM (TEST.dbo.APVENMAST APVENMAST
INNER JOIN
(SELECT APVENADDR.ADDR1,
APVENADDR.VENDOR_GROUP,
APVENADDR.VENDOR,
APVENMAST.VEN_CLASS
FROM TEST.dbo.APVENADDR APVENADDR
INNER JOIN TEST.dbo.APVENMAST APVENMAST
ON (APVENADDR.VENDOR_GROUP = APVENMAST.VENDOR_GROUP)
AND (APVENADDR.VENDOR = APVENMAST.VENDOR)
WHERE (APVENMAST.VEN_CLASS IS NOT NULL)) Subquery
ON (APVENMAST.VENDOR_GROUP = Subquery.VENDOR_GROUP)
AND (APVENMAST.VENDOR = Subquery.VENDOR))
INNER JOIN TEST.dbo.APVENLOC APVENLOC
ON (APVENMAST.VENDOR_GROUP = APVENLOC.VENDOR_GROUP)
AND (APVENMAST.VENDOR = APVENLOC.VENDOR)
WHERE (APVENMAST.VEN_CLASS IS NOT NULL)
Try this:
SELECT APVENMAST.VENDOR_GROUP
, APVENMAST.VENDOR
, APVENMAST.VENDOR_VNAME
, APVENMAST.VENDOR_CONTCT
, APVENMAST.TAX_ID
, APVENADDR.ADDR1
FROM TEST.dbo.APVENMAST APVENMAST
INNER JOIN (
select VENDOR_GROUP, VENDOR, ADDR1
, row_number() over (partition by VENDOR_GROUP, VENDOR order by ADDR1) r
from TEST.dbo.APVENADDR
) APVENADDR
ON APVENADDR.VENDOR_GROUP = APVENMAST.VENDOR_GROUP
AND APVENADDR.VENDOR = APVENMAST.VENDOR
AND APVENADDR.r = 1
--do you need this table; you're not using it...
--INNER JOIN TEST.dbo.APVENLOC APVENLOC
--ON APVENMAST.VENDOR_GROUP = APVENLOC.VENDOR_GROUP
--AND APVENMAST.VENDOR = APVENLOC.VENDOR
WHERE APVENMAST.VEN_CLASS IS NOT NULL
--if the above inner join was to filter results, you can do this instead:
and exists (
select top 1 1
from TEST.dbo.APVENLOC APVENLOC
ON APVENMAST.VENDOR_GROUP = APVENLOC.VENDOR_GROUP
AND APVENMAST.VENDOR = APVENLOC.VENDOR
)
I found another column in the APVENLOC table that I can filter on to get the unique vendor. Turns out if the vendor address is for the main office, the vendor location is set blank.
Easier than I thought it would be!
SELECT DISTINCT APVENMAST.VENDOR_GROUP,
APVENMAST.VENDOR,
APVENMAST.VENDOR_VNAME,
APVENADDR.ADDR1,
APVENMAST.VENDOR_SNAME,
APVENADDR.LOCATION_CODE,
APVENMAST.VEN_CLASS
FROM TEST.dbo.APVENMAST APVENMAST
INNER JOIN TEST.dbo.APVENADDR APVENADDR
ON (APVENMAST.VENDOR_GROUP = APVENADDR.VENDOR_GROUP)
AND (APVENMAST.VENDOR = APVENADDR.VENDOR)
WHERE (APVENADDR.LOCATION_CODE = ' ')

I am attempting to write a query that pulls Order information from various tables. I have hit a road block at the target date value.
It seems that every time a target date is changed a new row is added in that table. All I want is to be able to select only the newest Target Date. What should I do?
select Distinct
OR01001 AS OrderNumber,
OR01002 AS OrderType,
OR01003 AS CustomerCode,
OR01015 AS OrderDate,
OR01017 AS CustomerREP,
OR01018 AS ContactPerson,
OR01019 AS SalesmanNumber,
OR03011 - OR03012 AS OpenQuantity,
SC03003 AS StockBalance,
OR01050 AS WarehouseNumber,
OR01072 AS CustomerPO,
OR03005 AS ItemCode,
OR03002 AS LineNumber,
OR500100.OR50004 As TargetDate
from OR010100
INNER Join OR030100 ON OR030100.OR03001 = OR010100.OR01001
INNER Join SL010100 ON SL010100.SL01001 = OR010100.OR01003
INNER Join SC030100 ON SC030100.SC03001 = OR030100.OR03005
Inner JOIN OR500100 ON OR500100.OR50001 = OR010100.OR01001
where OR010100.OR01002 <> 0 AND OR010100.OR01002 <> 6 AND OR01017 = 'SLOTT'
Order by OR01017 ASC;
If I understand your columns correctly, here's one way:
SELECT ...,
OR500100A.OR50004 AS TargetDate
FROM ...
INNER JOIN OR500100 AS OR500100A ON OR500100A.OR50001 = OR010100.OR01001
AND NOT EXISTS(SELECT 1 FROM OR500100 AS OR500100B
WHERE OR500100B.OR5001 = OR010100.OR01001
AND OR500100B.OR50004 > OR500100A.OR50004)
...
This makes sure you only get one OR500100 row with the latest value in OR50004 for the given OR5001.
from what i understand,
SELECT
...
MAX(OR500100.OR50004) As TargetDate
FROM...
WHERE...
GROUP BY --everything but OR500100.OR50004
ORDER BY...
should do the trick

I am working on a query where I am trying to pull the minimum date where the owner contains WF in the table.
Table is similar to below:
Order Number
Create Date
Modified Date
Owner
for every order, I need to pull where the minimum modified date where the owner contains %WF%.
Any help would be greatly appreciated.
Thanks.
Here is the query that I have:
select distinct (ol.order_no),
min(os.assgn_dt) as MinDate,
ow.owner_desc,
ol.created_Date,
md.media_type_desc,
ow.owner_desc,
st.status_type_Desc,
os.comment,
tt.team_type_desc,
br.sdescrip as Branch,
ol.bgrp_cnt
from order_log ol
join activity_type att on ol.activity_type_id = att.activity_type_id
join branches br on ol.branch = br.lbranch
join regions rg on br.lregion = rg.lregion
join businessunit bu on rg.lbusinessunit = bu.lbusinessunit
join vwCurrentStatus vcs on vcs.order_no = ol.order_no
join order_status os on os.order_no = vcs.order_no
join owner ow on os.owner_name = ow.owner_id
join status_type st on st.status_type_id = os.status_type_id
join team_type tt on ow.team_type_id = tt.team_type_id
join media_type md on ol.media_type_id = md.media_type_id
join rep_name_xref rnx on rnx.order_no = ol.order_no
join rep_names rn on rn.user_id = rnx.user_id
where ow.owner_desc like '%WF%'
and ol.created_date > '01-01-2012'
and att.activity_type_id in ('14','16')
and tt.team_type_desc in ('1-10 Membership Team','government')
group by ol.order_no, ow.owner_desc, ol.created_Date,md.media_type_desc,ow.owner_desc,st.status_type_Desc, os.comment, tt.team_type_desc,br.sdescrip, ol.bgrp_cnt
Something like:
select order_number,min(modified_date) from orders where owner like '%WF%' group by order_number;
If you want the minimum order date for all orders where the owner contains 'WF', try:
SELECT MIN(ModifiedDate)
FROM MyTable
WHERE Owner like '%WF%'
Regarding what you said in the comments, try this:
SELECT t.Owner, t.ModifiedDate
FROM tablename t
WHERE t.ModifiedDate = (SELECT MIN(t2.ModifiedDate)
FROM tablename t2
WHERE t2.Owner like '%WF%')
It will give you the list of Owners that have the ModifiedDate equal to the Min(ModifiedDate) from a Owner with '%WF%'.
I have the following SQL query:
SELECT VehicleRegistrations.ID, VehicleRegistrations.VehicleReg,
VehicleRegistrations.Phone, VehicleType.VehicleTypeDescription,
dt.ID AS 'CostID', dt.IVehHire, dt.FixedCostPerYear, dt.VehicleParts,
dt.MaintenancePerMile, dt.DateEffective
FROM VehicleRegistrations
INNER JOIN VehicleType ON VehicleRegistrations.VehicleType = VehicleType.ID
LEFT OUTER JOIN (SELECT TOP (1) ID, VehicleRegID, DateEffective, IVehHire,
FixedCostPerYear, VehicleParts, MaintenancePerMile
FROM VehicleFixedCosts
WHERE (DateEffective <= GETDATE())
ORDER BY DateEffective DESC) AS dt
ON dt.VehicleRegID = VehicleRegistrations.ID
What I basically want to do is always select the top 1 record from the 'VehicleFixedCosts' table, where the VehicleRegID matches the one in the main query. What is happening here is that it's selecting the top row before the join, so if the vehicle registration of the top row doesn't match the one we're joining to it returns nothing.
Any ideas? I really don't want to have use subselects for each of the columns I need to return
Try this:
SELECT vr.ID, vr.VehicleReg,
vr.Phone, VehicleType.VehicleTypeDescription,
dt.ID AS 'CostID', dt.IVehHire, dt.FixedCostPerYear, dt.VehicleParts,
dt.MaintenancePerMile, dt.DateEffective
FROM VehicleRegistrations vr
INNER JOIN VehicleType ON vr.VehicleType = VehicleType.ID
LEFT OUTER JOIN (
SELECT ID, VehicleRegID, DateEffective, IVehHire, FixedCostPerYear, VehicleParts, MaintenancePerMile
FROM VehicleFixedCosts vfc
JOIN (
select VehicleRegID, max(DateEffective) as DateEffective
from VehicleFixedCosts
where DateEffective <= getdate()
group by VehicleRegID
) t ON vfc.VehicleRegID = t.VehicleRegID and vfc.DateEffective = t.DateEffective
) AS dt
ON dt.VehicleRegID = vr.ID
Subquery underneath dt might need some grouping but without schema (and maybe sample data) it's hard to say which column should be involved in that.
