Could somebody correct this join query? - sql

SELECT *
FROM {$dbp}auctions au, ic.imgurl
LEFT JOIN {$dbp}cache ic ON au.cache_id = ic.id
I'm baffled on where to set the alias for the second table (ic) and still only select the one column (imgurl).

"SELECT au.*, ic.imgurl FROM {$dbp}auctions au
LEFT JOIN {$dbp}cache ic ON au.cache_id = ic.id"
I think this is close to what you want. Your original query is selecting everything.

LEFT JOIN expression not supported

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

SQL View statement with 2 INNER JOINS

Can anyone help me with this issue I tried many times but still haven't found the solution
Here is the original View that I have in my database but now I made changes in the database and the view need to be changed also.
Here is the view as it was:
SELECT
[tableN].*,
[tabB].[att1] AS tabB_email, [tabB].[name] AS tabB_name,
[tabC].[name] AS tabC_name
FROM
[tabC]
INNER JOIN
([tableN]
INNER JOIN [tabB] ON [tableN].[sender_id] = [tabB].[ID])
ON [tabC].[ID] = [tableN].[recipient_id]
Here is what is the difficult point for me. Now I don't have this 2 tables tabB and tabC
They are now in one table tabX and have an identifier field roleId. I manage to get all the columns except the last one [tabC].[name] AS tabC_name
Any ideas?
Try like this
SELECT [tableN].*, [tabX].[att1] AS tabB_email, [tabX].[name] AS tabB_name,
t1.[name] AS tabC_name
FROM [tabX] as t INNER JOIN ([tableN] INNER JOIN [tabX]
ON [tableN].[sender_id] = [tabX].[roleid])
ON t.[roleid] = [tableN].[recipient_id]
SELECT [tableN].*, [Tabx] .[att1] AS tabB_email, [Tabx] .[name] AS tabB_name
FROM [Tabx] A
INNER JOIN [TABLEN] B
ON A.ROLEID=B.RECIPIENT_ID
SELECT [TableN].*, Bd.[email] AS bd_email, Bd.[showname] AS bd_name,
Pc.[showname] AS pc_name
FROM
[TABLE_X] AS Pc
INNER JOIN ([TableN]
INNER JOIN [TABLE_X] AS Bd
ON [TableN].[sender_id] = Bd.[ID] AND Bd.roleID = 1)
ON Pc.[ID] = [TableN].[recipient_id] AND Pc.roleID = 2
I finally find the the code that is working as needed

(emp_details_full1.city_code=Table1.city) AND
(emp_details_full1.Grade_Code=Table1.grade)
WHERE Table1.grade='02';
The first thing I would do is take the inner select and create a view from it.
This will provide a simple, easy to read, easy to debug sql code.
CREATE VIEW emp_details_full1
AS
SELECT iss_personal_detail.Specialization, iss_personal_detail.New_rank,
iss_personal_detail.Induction_tr, iss_personal_detail.Title,
iss_personal_detail.f_name, iss_personal_detail.m_name,
iss_personal_detail.l_name, iss_personal_detail.Father_Hus_Name,
iss_personal_detail.Category, iss_personal_detail.Community,
iss_personal_detail.SEX, iss_personal_detail.source_recruit,
iss_personal_detail.Pay_Parity, iss_personal_detail.[Date_Pay_ Parity],
iss_personal_detail.UPSC_Rank, iss_personal_detail.dob,
iss_personal_detail.doj_govt, iss_personal_detail.DOA_ISS,
iss_personal_detail.Batch, iss_personal_detail.Year_of_Exam,
iss_personal_detail.Native_Distt, iss_personal_detail.Native_State,
iss_personal_detail.[Highest Qualification],
iss_personal_detail.Languages_Known,
iss_personal_detail.Mother_Toung, iss_personal_detail.Marital_Status,
iss_personal_detail.E_mail_ID, iss_personal_detail.retire_reason,
iss_personal_detail.title_m, Present_Posting., ISS_MINISTRY_CODE_LIST.,
ISS_DEPARTMENT_CODE_LIST., ISS_CITY_CODE_LIST., Desig_Code.*,
Grade_Code.Grade_code
FROM ISS_CITY_CODE_LIST INNER JOIN( Grade_Code INNER JOIN (Desig_Code INNER JOIN
(((iss_personal_detail INNER JOIN Present_Posting ON iss_personal_detail.OID =
Present_Posting.OID) INNER JOIN ISS_MINISTRY_CODE_LIST
ON Present_Posting.ministry = ISS_MINISTRY_CODE_LIST.MINISTRY_CODE)
INNER JOIN ISS_DEPARTMENT_CODE_LIST ON
Present_Posting.department = ISS_DEPARTMENT_CODE_LIST.DEPARTMENT_CODE) ON
Desig_Code.Code = Present_Posting.designation) ON Grade_Code.Grade_code =
Present_Posting.Grade)
ON ISS_CITY_CODE_LIST.city_code=Present_Posting.office_city
Then the rest of the sql would look like this:
SELECT Table1.,emp_details_full1.
FROM Table1 LEFT JOIN emp_details_full1
ON (emp_details_full1.DEPARTMENT_CODE=Table1.department) AND
(emp_details_full1.MINISTRY_CODE=Table1.ministry) AND
(emp_details_full1.city_code=Table1.city) AND
(emp_details_full1.Grade_Code=Table1.grade) WHERE Table1.grade='02';
Now, if you look closely, you can see that there is a closing bracket missing between the end of the ON clause and the start of the WHERE clause.
So to fix that:
SELECT Table1.,emp_details_full1.
FROM Table1 LEFT JOIN emp_details_full1
ON (emp_details_full1.DEPARTMENT_CODE=Table1.department) AND
(emp_details_full1.MINISTRY_CODE=Table1.ministry) AND
(emp_details_full1.city_code=Table1.city) AND
(emp_details_full1.Grade_Code=Table1.grade)) WHERE Table1.grade='02';
Isn't that much easier to work with?

Ambiguous outer join in MS Access

Trying to create an outer join on two other joined tables when recieving this error - I just dont see how to create two separate queries to make it work. Subqueries don't seem to work either, any help appreciated. I get errors for the below query, thanks.
SELECT
CardHeader.CardID, CardHeader.CardDescription, CardHeader.GloveSize,
CardHeader.GloveDescription, CardDetail.Bin, CardDetail.ItemID, Items.ItemDescription,
Items.VCatalogID, CardDetail.ChargeCode, CardDetail.Quantity, Items.Cost, CardColors.ColorID
FROM
((Items
INNER JOIN
(CardHeader INNER JOIN CardDetail ON CardHeader.CardID = CardDetail.CardID) ON Items.ItemID = CardDetail.ItemID)
LEFT JOIN
CardColors ON CardDetail.ItemID = CardColors.ItemID)
INNER JOIN
Colors ON CardColors.ColorID = Colors.ID
ORDER BY
CardHeader.CardID;
I tried the following which runs but asks for the following parameters (which it shouldnt)
CardHeader.ID, MainQry.CardID
SELECT
MainQry.ID, MainQry.CardDescription, MainQry.GloveSize,
MainQry.GloveDescription, MainQry.Bin, MainQry.ItemID,
MainQry.ItemDescription, MainQry.VCatalogID, MainQry.ChargeCode,
MainQry.Quantity, MainQry.Cost, SubQry.ColorID
FROM
(SELECT
CardHeader.ID, CardHeader.CardDescription, CardHeader.GloveSize,
CardHeader.GloveDescription, CardDetail.Bin,
CardDetail.ItemID, Items.ItemDescription, Items.VCatalogID,
CardDetail.ChargeCode, CardDetail.Quantity, Items.Cost
FROM
Items
INNER JOIN
(CardHeader
INNER JOIN
CardDetail ON CardHeader.CardID = CardDetail.CardID) ON Items.ItemID = CardDetail.ItemID
) AS MainQry
LEFT JOIN
(SELECT
CardColors.ItemID, CardColors.ColorID
FROM
CardColors
INNER JOIN
Colors ON CardColors.ColorID = Colors.ID) AS SubQry ON MainQry.ItemID = SubQry.ItemID
ORDER BY
MainQry.CardID;
The second SQL statement can be corrected by reference to the first statement and the error. The error is that both CardHeader.ID and MainQry.CardID are prompting for a parameter, which indicates that the inner statement should include CardHeader.CardID, rather than CardHeader.ID

Super Slow Query - sped up, but not perfect... Please help

I posted a query yesterday (see here) that was horrible (took over a minute to run, resulting in 18,215 records):
SELECT DISTINCT
dbo.contacts_link_emails.Email, dbo.contacts.ContactID, dbo.contacts.First AS ContactFirstName, dbo.contacts.Last AS ContactLastName, dbo.contacts.InstitutionID,
dbo.institutionswithzipcodesadditional.CountyID, dbo.institutionswithzipcodesadditional.StateID, dbo.institutionswithzipcodesadditional.DistrictID
FROM
dbo.contacts_def_jobfunctions AS contacts_def_jobfunctions_3
INNER JOIN
dbo.contacts
INNER JOIN
dbo.contacts_link_emails
ON dbo.contacts.ContactID = dbo.contacts_link_emails.ContactID
ON contacts_def_jobfunctions_3.JobID = dbo.contacts.JobTitle
INNER JOIN
dbo.institutionswithzipcodesadditional
ON dbo.contacts.InstitutionID = dbo.institutionswithzipcodesadditional.InstitutionID
LEFT OUTER JOIN
dbo.contacts_def_jobfunctions
INNER JOIN
dbo.contacts_link_jobfunctions
ON dbo.contacts_def_jobfunctions.JobID = dbo.contacts_link_jobfunctions.JobID
ON dbo.contacts.ContactID = dbo.contacts_link_jobfunctions.ContactID
WHERE
(dbo.contacts.JobTitle IN
(SELECT JobID
FROM dbo.contacts_def_jobfunctions AS contacts_def_jobfunctions_1
WHERE (ParentJobID <> '1841')))
AND
(dbo.contacts_link_emails.Email NOT IN
(SELECT EmailAddress
FROM dbo.newsletterremovelist))
OR
(dbo.contacts_link_jobfunctions.JobID IN
(SELECT JobID
FROM dbo.contacts_def_jobfunctions AS contacts_def_jobfunctions_2
WHERE (ParentJobID <> '1841')))
AND
(dbo.contacts_link_emails.Email NOT IN
(SELECT EmailAddress
FROM dbo.newsletterremovelist AS newsletterremovelist))
ORDER BY EMAIL
With a lot of coaching and research, I've tuned it up to the following:
SELECT contacts.ContactID,
contacts.InstitutionID,
contacts.First,
contacts.Last,
institutionswithzipcodesadditional.CountyID,
institutionswithzipcodesadditional.StateID,
institutionswithzipcodesadditional.DistrictID
FROM contacts
INNER JOIN contacts_link_emails ON
contacts.ContactID = contacts_link_emails.ContactID
INNER JOIN institutionswithzipcodesadditional ON
contacts.InstitutionID = institutionswithzipcodesadditional.InstitutionID
WHERE
(contacts.ContactID IN
(SELECT contacts_2.ContactID
FROM contacts AS contacts_2
INNER JOIN contacts_link_emails AS contacts_link_emails_2 ON
contacts_2.ContactID = contacts_link_emails_2.ContactID
LEFT OUTER JOIN contacts_def_jobfunctions ON
contacts_2.JobTitle = contacts_def_jobfunctions.JobID
RIGHT OUTER JOIN newsletterremovelist ON
contacts_link_emails_2.Email = newsletterremovelist.EmailAddress
WHERE (contacts_def_jobfunctions.ParentJobID <> 1841)
GROUP BY contacts_2.ContactID
UNION
SELECT contacts_1.ContactID
FROM contacts_link_jobfunctions
INNER JOIN contacts_def_jobfunctions AS contacts_def_jobfunctions_1 ON
contacts_link_jobfunctions.JobID = contacts_def_jobfunctions_1.JobID
AND contacts_def_jobfunctions_1.ParentJobID <> 1841
INNER JOIN contacts AS contacts_1 ON
contacts_link_jobfunctions.ContactID = contacts_1.ContactID
INNER JOIN contacts_link_emails AS contacts_link_emails_1 ON
contacts_link_emails_1.ContactID = contacts_1.ContactID
LEFT OUTER JOIN newsletterremovelist AS newsletterremovelist_1 ON
contacts_link_emails_1.Email = newsletterremovelist_1.EmailAddress
GROUP BY contacts_1.ContactID))
While this query is now super fast (about 3 seconds), I've blown part of the logic somewhere - it only returns 14,863 rows (instead of the 18,215 rows that I believe is accurate).
The results seem near correct. I'm working to discover what data might be missing in the result set.
Can you please coach me through whatever I've done wrong here?
Thanks,
Russell Schutte
The main problem with your original query was that you had two extra joins just to introduce duplicates and then a DISTINCT to get rid of them.
Use this:
SELECT cle.Email,
c.ContactID,
c.First AS ContactFirstName,
c.Last AS ContactLastName,
c.InstitutionID,
izip.CountyID,
izip.StateID,
izip.DistrictID
FROM dbo.contacts c
INNER JOIN
dbo.institutionswithzipcodesadditional izip
ON izip.InstitutionID = c.InstitutionID
INNER JOIN
dbo.contacts_link_emails cle
ON cle.ContactID = c.ContactID
WHERE cle.Email NOT IN
(
SELECT EmailAddress
FROM dbo.newsletterremovelist
)
AND EXISTS
(
SELECT NULL
FROM dbo.contacts_def_jobfunctions cdj
WHERE cdj.JobId = c.JobTitle
AND cdj.ParentJobId <> '1841'
UNION ALL
SELECT NULL
FROM dbo.contacts_link_jobfunctions clj
JOIN dbo.contacts_def_jobfunctions cdj
ON cdj.JobID = clj.JobID
WHERE clj.ContactID = c.ContactID
AND cdj.ParentJobId <> '1841'
)
ORDER BY
email
Create the following indexes:
newsletterremovelist (EmailAddress)
contacts_link_jobfunctions (ContactID, JobID)
contacts_def_jobfunctions (JobID)
Do you get the same results when you do:
SELECT count(*)
FROM
dbo.contacts_def_jobfunctions AS contacts_def_jobfunctions_3
INNER JOIN
dbo.contacts
INNER JOIN
dbo.contacts_link_emails
ON dbo.contacts.ContactID = dbo.contacts_link_emails.ContactID
ON contacts_def_jobfunctions_3.JobID = dbo.contacts.JobTitle
SELECT COUNT(*)
FROM
contacts
INNER JOIN contacts_link_jobfunctions
ON contacts.ContactID = contacts_link_jobfunctions.ContactID
INNER JOIN contacts_link_emails
ON contacts.ContactID = contacts_link_emails.ContactID
If so keep adding each join conditon on until you don't get the same results and you will see where your mistake was. If all the joins are the same, then look at the where clauses. But I will be surprised if it isn't in the first join because the syntax you have orginally won't even work on SQL Server and it is pretty nonstandard SQL and may have been incorrect all along but no one knew.
Alternatively, pick a few of the records that are returned in the orginal but not the revised. Track them through the tables one at a time to see if you can find why the second query filters them out.
I'm not directly sure what is wrong, but when I run in to this situation, the first thing I do is start removing variables.
So, comment out the where clause. How many rows are returned?
If you get back the 11,604 rows then you've isolated the problems to the joins. Work though the joins, commenting each one out (remove the associated columns too) and figure out how many rows are eliminated.
As you do this, aim to find what is causing the desired rows to be eliminated. Once isolated, consider the join differences between the first query and the second query.
In looking at the first query, you could probably just modify that to eliminate any INs and instead do a EXISTS instead.
Consider your indexes as well. Any thing in the where or join clauses should probably be indexed.
