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 have some code:
CREATE OR REPLACE TEMPORARY VIEW cctv_join_1
AS
SELECT *
FROM cctv1_details AS A
LFET JOIN cctv3_details AS B ON (A.CDE_WR = B.CDE_WR) AND A.CDE_dist = B.CDE_dist
I then try
CREATE OR REPLACE TEMPORARY VIEW cctv_join_2
AS
(SELECT *
FROM cctv_join_1 AS A
LEFT JOIN cctv5_details AS B ON (A.CDE_WR = B.CDE_WR) AND (A.CDE_dist = B.CDE_dist))
but I get an error
Error in SQL statement: AnalysisException: Reference 'A.CDE_WR' is ambiguous, could be: A.CDE_WR, A.CDE_WR.; line 6 pos 4
in databricks. How can I deal with this?
This query:
SELECT *
FROM cctv1_details c1d LEFT JOIN
cctv3_details c3d
ON c1d.CDE_WR = c3d.CDE_WR AND c1d.CDE_dist = c3d.CDE_dist
is using SELECT *. The * is shorthand for all columns from both tables.
Obviously the combined columns from the two tables have duplicate column names; at least, CDE_WR and CDE_dist -- and there may be others. The general solution is to list all the columns out:
SELECT c1d.col1, c1d.col2, . . . c3d.colx, c3d.coly
FROM cctv1_details c1d LEFT JOIN
cctv3_details c3d
ON c1d.CDE_WR = c3d.CDE_WR AND c1d.CDE_dist = c3d.CDE_dist;
However, this is often shorted to:
SELECT c1d.*, c3d.colx, c3d.coly
FROM cctv1_details c1d LEFT JOIN
cctv3_details c3d
ON c1d.CDE_WR = c3d.CDE_WR AND c1d.CDE_dist = c3d.CDE_dist;
Note that I changed the table aliases to be reasonable abbreviations for the table names, making the query much clearer and easier to maintain.
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 have the following SQL string which tries to combine an INNER JOIN with a LEFT JOIN in the FROM section.
As you can see I use table VIP_APP_VIP_SCENARIO_DETAIL_LE to perform the query. When I use it against this table, Access give me an "Invalid Operation" error.
Interestingly, when I use the EXACT same query using the VIP_APP_VIP_SCENARIO_DETAIL_BUDGET or VIP_APP_VIP_SCENARIO_DETAIL_ACTUALS table, it performs flawlessly.
So why would it work on two tables but not the other? All fields are in all tables and the data types are correct.
As a side note: on the query with the error, if I change the LEFT JOIN to an INNER JOIN, it runs with no problem! I really need a LEFT JOIN though.

tried to mock this up in SQL server with some tables of my own, but the structure seemed to work, this follows the pattern referenced above. (hopefully no syntax errors left here)

Had help from a friend and we discovered that it was a casting problem between a linked Oracle table and the Access table. To fix the problem we casted both sides of the linked fields to a string:
CSTR(D.[MATERIAL_NUMBER]) = CSTR(V.[ITEM_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 = (?)
);
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!
