I need to do a query with a left outer join just like below, however Access is showing a warning dialog "JOIN expression not supported".I understand that Access doesn't support INNER JOIN nested inside a LEFT JOIN but as I am a beginner in SQL I don't see any other way to get the same result.
The goal of the query is to get everything that is in the select even when InvoiceItems.Amount is null.
SELECT MainOrder.OrderNumber, OrderComponent.ArticleNumber, SupplierOrderMain.*, InvoiceItems.Amount
FROM InvoiceItems LEFT JOIN
((MainOrder INNER JOIN
OrderComponent
ON MainOrder.OrderNumber = OrderComponent.OrderNumber
) INNER JOIN
SupplierOrderMain
ON OrderComponent.ID = SupplierOrderMain.OrderComponentID
)
ON InvoiceItems.OrderComponent = OrderComponent.ID;
I'm not sure why you would want outer joins in this situation at all (you don't explain why). But just start with the table where you want to keep everything and work from there:
SELECT MainOrder.OrderNumber, OrderComponent.ArticleNumber, SupplierOrderMain.*, InvoiceItems.Amount
FROM ((InvoiceItems LEFT JOIN
OrderComponent
ON InvoiceItems.OrderComponent = OrderComponent.ID
) LEFT JOIN
MainOrder
ON MainOrder.OrderNumber = OrderComponent.OrderNumber
) LEFT JOIN
SupplierOrderMain
ON OrderComponent.ID = SupplierOrderMain.OrderComponentID
I'm trying to join a query and a sub-query in Access but haven't the faintest idea on how to do that. Rather than saving the sub-query as a different query and then joining it to the main query.
Main query (with reference to sub-query):
SELECT tb200_IraDataIn.tb200_niarnum, tb206_IraAccount.tb206_IraAccDesc,
tb206_IraAccount.tb206_IraAccNum, tb15_Securities.tb15_IsActiveRegister,
tb15_Securities.tb15_NiarDesc, tb15_Securities.tb15_ManpikID, tb200_IraDataIn.tb200_Shovi, tb10_Afik.tb10_InvestTool,
tb206_IraAccount.tb206_IsActive, tb200_IraDataIn.tb200_Shovi,
tb200_IraDataIn.tb200_Shovi/SubQuery1.SumOftb200_Shovi AS Expr1
FROM SubQuery1
INNER JOIN (tb10_Afik
INNER JOIN (tb15_Securities
INNER JOIN (tb206_IraAccount
INNER JOIN tb200_IraDataIn
ON tb206_IraAccount.tb206_IraAccNum = tb200_IraDataIn.tb200_accountNumber)
ON tb15_Securities.tb15_NiarID = tb200_IraDataIn.tb200_niarnum)
ON (tb10_Afik.tb10_AfikID = tb200_IraDataIn.tb200_afik) AND (tb10_Afik.tb10_Erp =tb200_IraDataIn.tb200_ERP))
ON SubQuery1.tb206_IraAccNum = tb206_IraAccount.tb206_IraAccNum
WHERE (((tb15_Securities.tb15_IsActiveRegister)=Yes) AND ((tb10_Afik.tb10_InvestTool)=1
Or (tb10_Afik.tb10_InvestTool)=4 Or (tb10_Afik.tb10_InvestTool)=21 Or
(tb10_Afik.tb10_InvestTool)=3) AND ((tb206_IraAccount.tb206_IsActive)=Yes) AND
(([tb200_IraDataIn].[tb200_Shovi]/[SubQuery1].[SumOftb200_Shovi])>0.1));
subquery (saved as SubQuery1):
SELECT tb206_IraAccount.tb206_IraAccDesc, tb206_IraAccount.tb206_IraAccNum, Sum(tb200_IraDataIn.tb200_Shovi) AS SumOftb200_Shovi
FROM tb206_IraAccount
INNER JOIN tb200_IraDataIn ON tb206_IraAccount.tb206_IraAccNum = tb200_IraDataIn.tb200_accountNumber
WHERE (((tb206_IraAccount.tb206_IsActive)=Yes))
GROUP BY tb206_IraAccount.tb206_IraAccDesc, tb206_IraAccount.tb206_IraAccNum;
How can I put the sql statement of the sub-query inside the same Sql statement of the main query, unlike now?
Thanks!
Nest between parentheses. Nothing else in the main query changes.
SELECT
...
FROM (SELECT tb206_IraAccount.tb206_IraAccDesc, tb206_IraAccount.tb206_IraAccNum, Sum(tb200_IraDataIn.tb200_Shovi) AS SumOftb200_Shovi
FROM tb206_IraAccount
INNER JOIN tb200_IraDataIn ON tb206_IraAccount.tb206_IraAccNum = tb200_IraDataIn.tb200_accountNumber
WHERE (((tb206_IraAccount.tb206_IsActive)=Yes))
GROUP BY tb206_IraAccount.tb206_IraAccDesc, tb206_IraAccount.tb206_IraAccNum) AS SubQuery1

I am querying the aact database from clinicaltrials.gov. The database model is right here: https://aact.ctti-clinicaltrials.org/schema. I have two schemas that I am selecting from (ctgov, proj_cdek_standard_orgs). I am trying to join two select statements. edit: I have now tried aliasing my subqueries, but that still does nothing. I get the following error:
(SELECT ctgov.sponsors.name, ctgov.sponsors.nct_id, ctgov.sponsors.id, ctgov.studies.phase
FROM ctgov.sponsors, ctgov.studies
WHERE ctgov.sponsors.nct_id=ctgov.studies.nct_id) A
FULL [OUTER] JOIN
(SELECT proj_cdek_standard_orgs.cdek_synonyms.id, proj_cdek_standard_orgs.cdek_synonyms.name
FROM proj_cdek_standard_orgs.cdek_synonyms) B
ON
A.name = B.name;
I can do both select statements perfectly fine on their own, but I try the query and I get this error:
ERROR: syntax error at or near "t1" LINE 7: ) t1
What did I do wrong and how do I use joins without getting syntax errors?
Please use below query,
SELECT ctgov.sponsors.name, ctgov.sponsors.nct_id, ctgov.sponsors.id,
ctgov.studies.phase, proj_cdek_standard_orgs.cdek_synonyms.id,
proj_cdek_standard_orgs.cdek_synonyms.name
FROM ctgov.sponsors, ctgov.studies, proj_cdek_standard_orgs.cdek_synonyms
WHERE ctgov.sponsors.nct_id=ctgov.studies.nct_id
and proj_cdek_standard_orgs.cdek_synonyms.name = ctgov.sponsors.name;
But the right way is to use traditional joins,
SELECT ctgov.sponsors.name, ctgov.sponsors.nct_id, ctgov.sponsors.id,
ctgov.studies.phase, proj_cdek_standard_orgs.cdek_synonyms.id,
proj_cdek_standard_orgs.cdek_synonyms.name
FROM ctgov.sponsors
INNER JOIN ctgov.studies
ON (ctgov.sponsors.nct_id=ctgov.studies.nct_id)
INNER JOIN proj_cdek_standard_orgs.cdek_synonyms
ON (proj_cdek_standard_orgs.cdek_synonyms.name = ctgov.sponsors.name);
You can change it to LEFT or FULL OUTER JOIN according to your requirement.
You have to provide an alias to the sub-queries. Also you should not use implicit joins as you have used in first subquery, always try to use explicit joins.
SELECT
*
FROM
(
SELECT
ctgov.sponsors.name, ctgov.sponsors.nct_id, ctgov.sponsors.id, ctgov.studies.phase
FROM ctgov.sponsors
JOIN ctgov.studies
ON ctgov.sponsors.nct_id=ctgov.studies.nct_id
) t1
FULL JOIN
(
SELECT
proj_cdek_standard_orgs.cdek_synonyms.id, proj_cdek_standard_orgs.cdek_synonyms.name
FROM proj_cdek_standard_orgs.cdek_synonyms
) t2
ON
t1.name = t2.name;

The problem is the second query, the "recursive one" is getting the data I expect since I can't do the LEFT JOINs like in the first query. (At least to my understanding).
If I remove the fetching of the data that requires the LEFT (Outer) JOINs then the recursion works perfectly. My problem is I need both. Is there a way I can accomplish this?
Per http://msdn.microsoft.com/en-us/library/ms175972.aspx you can not have a left/right/outer join in a recursive CTE.
For a recursive CTE you can't use a subquery either so I sugest following this example.
They use two CTE's. The first is not recursive and does the left join to get the data it needs. The second CTE is recursive and inner joins on the first CTE. Since CTE1 is not recursive it can left join and supply default values for the missing rows and is guarenteed to work in the inner join.
However, you can also duplicate a left join with a union and subselect though it isn't really useful normally but it is interesting.
In that case, you would keep your first statement how it is. It will match all rows that join successfully.
Then UNION that query with another query that removes the join, but has a
NOT EXISTS(SELECT 1 FROM MISSING_ROWS_TABLE WHERE MAIN_TABLE.JOIN_CONDITION = MISSING_ROWS_TABLE.JOIN_CONDITION)
This gets all the rows that failed the previous join condition in query 1. You can replace the colmuns you would get from MISSING_ROWS_TABLE with NULL. I had to do this once using a coding framework that didn't support outer joins. Since recursive CTE's don't allow subqueries you have to use the first solution.
I want to join two table CUSTMR and DEPRMNT.
My needed is: LEFT OUTER JOIN OF two or more Tables with subquery inside the LEFT OUTER JOIN as shown below:
Table: CUSTMR , DEPRMNT
Query as:
SELECT
cs.CUSID
,dp.DEPID
FROM
CUSTMR cs
LEFT OUTER JOIN (
SELECT
dp.DEPID
,dp.DEPNAME
FROM
DEPRMNT dp
WHERE
dp.DEPADDRESS = 'TOKYO'
)
ON (
dp.DEPID = cs.CUSID
AND cs.CUSTNAME = dp.DEPNAME
)
WHERE
cs.CUSID != ''
Here the subquery is:
SELECT
dp.DEPID, dp.DEPNAME
FROM
DEPRMNT dp
WHERE
dp.DEPADDRESS = 'TOKYO'
Is it possible to write such subquery inside LEFT OUTER JOIN?
I am getting an error when running this query on my DB2 database.
You need the "correlation id" (the "AS SS" thingy) on the sub-select to reference the fields in the "ON" condition. The id's assigned inside the sub select are not usable in the join.
SELECT
cs.CUSID
,dp.DEPID
FROM
CUSTMR cs
LEFT OUTER JOIN (
SELECT
DEPID
,DEPNAME
FROM
DEPRMNT
WHERE
dp.DEPADDRESS = 'TOKYO'
) ss
ON (
ss.DEPID = cs.CUSID
AND ss.DEPNAME = cs.CUSTNAME
)
WHERE
cs.CUSID != ''
I think you don't have to use sub query in this scenario.You can directly left outer join the DEPRMNT table .
While using Left Outer Join ,don't use columns in the RHS table of the join in the where condition, you ll get wrong output
