I’m using multiple joins for a specific logic , but encountered a problem . Some of the records has 1-2 relation in one of the tables which mess up my output. I want to concat all these string so it will appear it one record, but I don’t know how to do it in sql server . In oracle and MySQL it’s easy but I tried playing with online examples and failed miserably.
My query:
SELECT c.customerName,c.Guid,p.campaignTitle ,
(SELECT k.campaignTitle FROM [DEV_TEST2].[dbo].campaigns l JOIN [DEV_TEST2].[dbo].campaignstitle k on k.campaignname = l.campaignname where l.campaignid = t.referrerurl) as Referrertitle,
t.activitydate,t.type
FROM [DEV_TEST2].[dbo].campaignknowncustomers c
join [DEV_TEST2].[dbo].[CampaignCustomerMatch] t ON(c.guid = t.visitorexternalid)
join [DEV_TEST2].[dbo].campaigns s ON(t.url = s.campaignid)
join [DEV_TEST2].[dbo].campaignstitle p on(s.campaignname = p.campaignname)
order by customername,activitydate
My problem is with campaigntitle column and referrertitle correlated query. Both come from the same table. I need to concat it and show only 1 row per ‘customername, guid, activitydate’

I'm working with MS Access, trying to join 3 tables together. But i'm getting message "JOIN EXPRESSION NOT SUPPORTED.".
Basically I want to join just 2 tables which are A_01HWeekEHCalendar and A00_Plant. A00_Plant requires 3 column to join; Plant_Product, Plant_Code, and Plant_Name. Plant_Product, Plant_Code is ok, but there is no column to match Plant_Product. so I have to add A_ProductGroup
I'm not sure if it can't be done in one Query or it's error from my SYNTAX. or there will be another way to do that without separate Queries.
I also add a picture of what I want and try to run and get error.
Thanks.
SELECT
A_01HWeekEHCalendar.RunNo_H,
A_01HWeekEHCalendar.Audit_Week,
A_01HWeekEHCalendar.CurrentYear,
A_01HWeekEHCalendar.CurrentWeek,
A_01HWeekEHCalendar.TTSMonth,
A_01HWeekEHCalendar.Audit_Plant,
A_01HWeekEHCalendar.Audit_plantname,
A_01HWeekEHCalendar.Audit_Qacode,
A_01HWeekEHCalendar.Audit_Qaname,
A_01HWeekEHCalendar.Audit_Product,
A00_Plant.HCA_StartDate
FROM
(A_01HWeekEHCalendar LEFT JOIN A_ProductGroup
ON A_01HWeekEHCalendar.Audit_Product = A_ProductGroup.R_Code)
LEFT JOIN A00_Plant
ON A_01HWeekEHCalendar.Audit_plantname = A00_Plant.Plant_Name
AND A_01HWeekEHCalendar.Audit_Plant = A00_Plant.Plant_Code
AND A_ProductGroup.R_Code = A00_Plant.Plant_Product;
You are lucky because you want only one column. You can work around this problem using a correlated subquery:
SELECT . . .,
(SELECT TOP (1) A00_Plant.HCA_StartDate
FROM A00_Plant
WHERE A_01HWeekEHCalendar.Audit_plantname = A00_Plant.Plant_Name
AND
A_01HWeekEHCalendar.Audit_Plant = A00_Plant.Plant_Code AND
A_ProductGroup.R_Code = A00_Plant.Plant_Product
) as HCA_StartDate
FROM A_01HWeekEHCalendar LEFT JOIN
A_ProductGroup
ON A_01HWeekEHCalendar.Audit_Product = A_ProductGroup.R_Code ;
I'm trying to join 4 tables that have a somewhat complex relationship. Because of where this will be used, it needs to be contained in a single query, but I'm having trouble since the primary query and the IN clause query both join 2 tables together and the lookup is on two columns.
The goal is to input a SalesNum and SalesType and have it return the Price
Tables and relationships:
sdShipping
SalesNum[1]
SalesType[2]
Weight[3]
sdSales
SalesNum[1]
SalesType[2]
Zip[4]
spZones
Zip[4]
Zone[5]
spPrices
Zone[5]
Price
Weight[3]
Here's my latest attempt in T-SQL:
SELECT
spp.Price
FROM
spZones AS spz
LEFT OUTER JOIN
spPrices AS spp ON spz.Zone = spp.Zone
WHERE
(spp.Weight, spz.Zip) IN (SELECT ship.Weight, sales.Zip
FROM sdShipping AS ship
LEFT OUTER JOIN sdSales AS sales ON sales.SalesNum = ship.SalesNum
AND sales.SalesType = ship.SalesType
WHERE sales.SalesNum = (?)
AND ship.SalesType = (?));
SQL Server Management Studio says I have an error in my syntax near ',' (appropriately useless error message). Does anybody have any idea whether this is even allowed in Microsoft's version of SQL? Is there perhaps another way to accomplish it? I've seen the multi-key IN questions answered on here, but never in the case where both sides require a JOIN.
Many databases do support IN on tuples. SQL Server is not one of them.
Use EXISTS instead:
SELECT spp.Price
FROM spZones spz LEFT OUTER JOIN
spPrices spp
ON spz.Zone = spp.Zone
WHERE EXISTS (SELECT 1
FROM sdShipping ship LEFT JOIN
sdSales sales
ON sales.SalesNum = ship.SalesNum AND
sales.SalesType = ship.SalesType
WHERE spp.Weight = ship.Weight AND spz.Zip = sales.Zip AND
sales.SalesNum = (?) AND
ship.SalesType = (?)
);
I pop into a problem recently, and Im sure its because of how I Join them.
this is my code:
select LP_Pending_Info.Service_Order,
LP_Pending_Info.Pending_Days,
LP_Pending_Info.Service_Type,
LP_Pending_Info.ASC_Code,
LP_Pending_Info.Model,
LP_Pending_Info.IN_OUT_WTY,
LP_Part_Codes.PartCode,
LP_PS_Codes.PS,
LP_Confirmation_Codes.SO_NO,
LP_Pending_Info.Engineer_Code
from LP_Pending_Info
join LP_Part_Codes
on LP_Pending_Info.Service_order = LP_Part_Codes.Service_order
join LP_PS_Codes
on LP_Pending_Info.Service_Order = LP_PS_Codes.Service_Order
join LP_Confirmation_Codes
on LP_Pending_Info.Service_Order = LP_Confirmation_Codes.Service_Order
order by LP_Pending_Info.Service_order, LP_Part_Codes.PartCode;
For every service order I have 5 part code maximum.
If the service order have only one value it show the result correctly but when it have more than one Part code the problem begin.
for example: this service order"4182134076" has only 2 part code, first'GH81-13601A' and second 'GH96-09938A' so it should show the data 2 time but it repeat it for 8 time. what seems to be the problem?
If your records were exactly the same the distinct keyword would have solved it.
However in rows 2 and 3 which have the same Service_Order and Part_Code if you check the SO_NO you see it is different - that is why distinct won't work here - the rows are not identical.
I say you have some problem in one of the conditions in your joins. The different data is in the SO_NO column so check the raw data in the LP_Confirmation_Codes table for that Service_Order:
select * from LP_Confirmation_Codes where Service_Order = 4182134076
I assume you are missing an and with the value from the LP_Part_Codes or LP_PS_Codes (but can't be sure without seeing those tables and data myself).
By this sentence If the service order have only one value it show the result correctly but when it have more than one Part code the problem begin. - probably you are missing and and with the LP_Part_Codes table
Based on your output result, here are the following data that caused multiple output.
Service Order: 4182134076 has :
2 PartCode which are GH81-13601A and GH96-09938A
2 PS which are U and P
2 SO_NO which are 1.00024e+09 and 1.00022e+09
Therefore 2^3 returns 8 rows. I believe that you need to check where you should join your tables.
Use DINTINCT
select distinct LP_Pending_Info.Service_Order,LP_Pending_Info.Pending_Days,
LP_Pending_Info.Service_Type,LP_Pending_Info.ASC_Code,LP_Pending_Info.Model,
LP_Pending_Info.IN_OUT_WTY, LP_Part_Codes.PartCode,LP_PS_Codes.PS,
LP_Confirmation_Codes.SO_NO,LP_Pending_Info.Engineer_Code
from LP_Pending_Info
join LP_Part_Codes on LP_Pending_Info.Service_order = LP_Part_Codes.Service_order
join LP_PS_Codes on LP_Part_Codes.Service_Order = LP_PS_Codes.Service_Order
join LP_Confirmation_Codes on LP_PS_Codes.Service_Order = LP_Confirmation_Codes.Service_Order
order by LP_Pending_Info.Service_order, LP_Part_Codes.PartCode;
distinct will not return duplicates based on your select. So if a row is same, it will only return once.
My title is probably not very clear, so I made a little schema to explain what I'm trying to achieve. The xxxx_uid labels are foreign keys linking two tables.
Goal: Retrieve a column from the grids table by giving a proj_uid value.
I'm not very good with SQL joins and I don't know how to build a single query that will achieve that.
Actually, I'm doing 3 queries to perform the operation:
1) This gives me a res_uid to work with:
select res_uid from results where results.proj_uid = VALUE order by res_uid asc limit 1"
2) This gives me a rec_uid to work with:
select rec_uid from receptor_results
inner join results on results.res_uid = receptor_results.res_uid
where receptor_results.res_uid = res_uid_VALUE order by rec_uid asc limit 1
3) Get the grid column I want from the grids table:
select grid_name from grids
inner join receptors on receptors.grid_uid = grids.grid_uid
where receptors.rec_uid = rec_uid_VALUE;
Is it possible to perform a single SQL that will give me the same results the 3 I'm actually doing ?
You're not limited to one JOIN in a query:
select grids.grid_name
from grids
inner join receptors
on receptors.grid_uid = grids.grid_uid
inner join receptor_results
on receptor_results.rec_uid = receptors.rec_uid
inner join results
on results.res_uid = receptor_results.res_uid
where results.proj_uid = VALUE;
select g.grid_name
from results r
join resceptor_results rr on r.res_uid = rr.res_uid
join receptors rec on rec.rec_uid = rr.rec_uid
join grids g on g.grid_uid = rec.grid_uid
where r.proj_uid = VALUE
a small note about names, typically in sql the table is named for a single item not the group. thus "result" not "results" and "receptor" not "receptors" etc. As you work with sql this will make sense and names like you have will seem strange. Also, one less character to type!
This SQL is beyond my expertise. I think it should be fairly easy for someone with experience. Here is what I have so far..
SQL is as follows:
UPDATE (Tbl_Stg_Project_Schedule_Dates
INNER JOIN Tbl_Child_ITN ON Tbl_Stg_Project_Schedule_Dates.ms_itn = Tbl_Child_ITN.ITN)
INNER JOIN Tbl_Schedule ON Tbl_Child_ITN.Id = Tbl_Schedule.ID SET Tbl_Schedule.a_construction_start = [Tbl_Stg_Project_Schedule_Dates].[ms_start_date]
WHERE (((Tbl_Stg_Project_Schedule_Dates.ms_tempt_id) In (16,17,18,19,20,21,22,23)));
I want to add one last condition to this being that I only want the minimum of [Tbl_Stg_Project_Schedule_Dates].[ms_start_date] to update the table. I've tried the obvious of wrapping the field in Min, and also tried creating a separate aggregate select statement first (to get the min value with other criteria) that I then tried to create the update query from in new query but no luck.
I believe this is valid Access/Jet SQL. The idea here is to use a subquery to look up the earliest date among all the rows in your subset. I'm not sure if ms_itn was the right column to correlate on but hopefully you get the idea:
UPDATE (Tbl_Stg_Project_Schedule_Dates
INNER JOIN Tbl_Child_ITN ON Tbl_Stg_Project_Schedule_Dates.ms_itn = Tbl_Child_ITN.ITN)
INNER JOIN Tbl_Schedule ON Tbl_Child_ITN.Id = Tbl_Schedule.ID
SET Tbl_Schedule.a_construction_start = [Tbl_Stg_Project_Schedule_Dates].[ms_start_date]
WHERE (((Tbl_Stg_Project_Schedule_Dates.ms_tempt_id) In (16,17,18,19,20,21,22,23)))
and [Tbl_Stg_Project_Schedule_Dates].[ms_start_date] = (
select min(sd.[ms_start_date])
from [Tbl_Stg_Project_Schedule_Dates] as sd
where sd.ms_itn = [Tbl_Stg_Project_Schedule_Dates].ms_itn
)
