I am trying to query in SQL and I can not resolve it.
I have a table tCliente:
What I want to do is a JOIN with the same table to find each pair of clients that lives in the same city.
I try to do this:
SELECT DISTINCT c.codiClien, c.nombreClien, c1.codiClien, c1.nombreClien, c.ciudadClien
FROM tCliente c
INNER JOIN tCliente c1 ON c.ciudadClien = c1.ciudadClien
and get this:
But I should get this:
I know I have to filter data, but I have tried many things and I can not find the solution.
Also, I tried to use GROUP BY but it is not possible. I wanted to group by pair, that is, something like this:
...
GROUP BY c.codiClien, c1.codiClien
But in doing so I get errors in the query. Could someone please help me? Thanks
Note:
When using ON in the INNER JOIN, I would like to know if it is "possible" to do that or should not do it, because the usual thing is to do tb1.id = tb2.id
You must exclude itself on the inner join.
SELECT c.codiClien, c.nombreClien, c1.codiClien, c1.nombreClien, c.ciudadClien
FROM tCliente c
INNER JOIN tCliente c1
ON c.ciudadClien = c1.ciudadClien
AND c.codiClien < c1.codiClien;

I have 7 Tables as per attached following Image.
I will either enter Engine Number or Chassis Number and it should show the respective tables information (these tables have only mentioned fields) so all fields can be shown as result.
I can use hard coded Engine Number or Chassis Number. Every time of execution of this Query, I will hard code the required Engine/Chassis Number and will get the result.
Can anybody please help me to write this query for me?

This might be a starting point for your solution.
SELECT prod.EngineNo AS engNo, prod.ChassisNo, doral.doralNo [, table.column [AS name]]
FROM DOProductSpecsDetais AS prod
INNER JOIN DORAL AS doral
ON prod.DOProductSpecsDetailID = doral.DOProductSpecsID
INNER JOIN DOProductDetail AS prodDetail
ON prod.DOProductDetailID = prodDetail.DOProductDetailID
WHERE prod.ChassisNo = '<input>' OR prod.EngineNo='<input>'
Between the SELECT and the FROM Statement, you can select any column out of your JOIN.
You can cascade as many JOINs as you like...
Which DBMS are you going to use?
One suggestion: Try to simplify the names of your columns, if possible.
One more: If you just started to do Database things, it is always helpful to start a test environment and use a client tool.
You can write query something like this:
select * from
DoProductSpecsDetail tbl1 inner join Doral tbl2
on tbl1.DoProductSpecsDetailId = tbl2.DoProductSpecsId
inner join DoproductDetail tbl3
on tbl1.DoProductDetailId = tbl3.DoProductDetailId
inner join ProductColor tbl4
on tbl1.ProductColorId = tbl4.ProductColorId
inner join DoDetail tbl5
on tbl3.DeliveryOrderDetailId = tbl5.DeliveryOrderId
inner join ProductMain tbl6
on tbl3.ProductId = tbl6.ProductId
inner join BPMain tbl7
on tbl5.BusinessPartnerId = tbl7.BusinessPartnerId
When I try to execute this SQL query, I get an error and I don't know how to correct it
select *
from pg_specialites_annees pgs
where pgs.NOM_FR like '%tets%'
left join pg_specialites_parametres pgsp on pgsp.ID_SPECIALITE = pgs.ID_SPECIALITE;
When I remove the LIKE it works, but I need a specific row.
Please help me, I don't know how to do it. I want to show some details for a specific row in table from another table.
Your LEFT JOIN needs to come before the WHERE:
Select *
From pg_specialites_annees pgs
Left Join pg_specialites_parametres pgsp on pgsp.ID_SPECIALITE = pgs.ID_SPECIALITE
Where pgs.NOM_FR Like '%tets%';
Put your where clause after the join clause :
select * from pg_specialites_annees pgs
left join pg_specialites_parametres pgsp on pgsp.ID_SPECIALITE = pgs.ID_SPECIALITE;
where pgs.NOM_FR like '%tets%'
SELECT
Trs.itemID, Trs.imtName, Trs.sumQty, Sum(whiQty)
FROM
((SELECT
trsitemID AS itemID, trsimtName AS imtName,
Sum(trsQty) As sumQty
FROM
tblTransactionSub AS T
WHERE
trstraID = 1231
AND trsActive = True
GROUP BY
trsitemID, trsimtName) AS Trs
INNER JOIN
tblWarehouseItem AS WHI ON Trs.itemID = WHI.whiitemID)
RIGHT JOIN
WHI ON Trs.trswhiID = WHI.whiID
WHERE
whiActive = True
AND whiCansel = False
AND whiwrhID = 19
GROUP BY
Trs.itemID,Trs.imtName, Trs.sumQty
HAVING
SUM(whiQty) < Trs.sumQty
If you please help me me out since I am new to SQL commands I can not easily find my mistake.
Thanks in advance
The error that occurred when I added the Right Join is:
Join expression not supported
In MS Access, you have to use parenthesises with multiple joins:
select ...
from
((table1
... join table2 on ...)
... join table3 on ...)
... join tableN
/edit/
As OP question changes its syntax often, then my answer seems out of place :) Initially there were no parens there.
About RIGHT JOIN: You need to use table name (or entire subselect) after JOIN keyword, not skip it or use some other alias. Your query part
RIGHT JOIN
WHI ON Trs.trswhiID = WHI.whiID
currently uses alias WHI, which is wrong in two ways: 1) it is not table name 2) it is already used. You need something like this:
RIGHT JOIN
tblWarehouseItem AS WHI2 ON Trs.trswhiID = WHI2.whiID
It could be possible that MS Access restricts your kind of JOINs usage (like INNER join should not come after LEFT join); I have currently no possibility to check precise rules.
Your problem is that you have no table name after the RIGHT JOIN:
RIGHT JOIN
ON Trs.trswhiID = WHI.whiID
Should be:
RIGHT JOIN YOURTABLENAMEHERE as alias
ON Trs.trswhiID = WHI.whiID
However, you have already defined Trs and Whi, so I have no idea what table you want there, or why. Perhaps you just want to change the INNER JOIN to a LEFT JOIN or RIGHT JOIN.
I am joining 2 tables using RIGHT JOIN statement. I used below query and it works good. However it still display all data whenever I tried to select specific user
SELECT TBLNOTIFICATIONS.NOTIFICATION_ID, TBLNOTIFICATIONS.NOTIFICATION_TYPE, FILENAMES_LIST.LOCATION_FILENAME, TBLNOTIFICATIONS.NOTIFICATION_DATE
FROM TBLNOTIFICATIONS
RIGHT JOIN FILENAMES_LIST
ON TBLNOTIFICATIONS.NOTIFICATION_ID=FILENAMES_LIST.NOTIFICATION_ID
WHERE TBLNOTIFICATIONS.USER_ID='JCON'
What should I do to select data from specific user?
Thanks in advance.
You are filtering on the left table, so all the data of the right table will still be shown.
It is probably enough to change the query to a LEFT JOIN to get the results you want.
Besides that, you can use aliases to make your query more readable, like so:
SELECT tn.NOTIFICATION_ID, tn.NOTIFICATION_TYPE, fl.LOCATION_FILENAME, tn.NOTIFICATION_DATE
FROM TBLNOTIFICATIONS AS tn
LEFT JOIN FILENAMES_LIST AS fl
ON tn.NOTIFICATION_ID = fl.NOTIFICATION_ID
WHERE tn.USER_ID='JCON'
Ok.. So I'm trying to improve my SQL skills and have a question. Here is a screen shot of the schema.

Alright so I'm selecting a bunch of Report Bundles and other rows from a table you can see. I've got these two tables joining together correctly and displaying what should be returned. Now I need to add another field onto my result rows that states what type of report this is. How can I join up to the ReportGroupType table through the ReportBundleGroup table without getting a shwack of results?
Here is the query I am using so far.
SELECT *
FROM ReportBundleCustomerVisibility INNER JOIN ReportBundle
ON ReportBundleCustomerVisibility.ReportBundleID = ReportBundle.ID
WHERE ReportBundleCustomerVisibility.ReferenceCustomerID = 2303
Thanks again SO
SELECT *
FROM ReportBundleCustomerVisibility AS v
JOIN ReportBundle AS b ON b.ID = v.ReportBundleID
JOIN ReportBundleGroup AS g ON b.ID = g.ReportBundleID
JOIN ReportGroupTYpe AS t ON t.ID = g.ReportGroupTypeID
WHERE v.ReferenceCustomerID = 2303
It sounds like you just need another inner join to get the information you need. You can think about the second join as joining the result of the join with the ReportGroupType table. I added parenthesis to try to join the two sets the second INNER JOIN is operating on.
SELECT * FROM ((ReportBundleCustomerVisibility
INNER JOIN ReportBundle ON ReportBundleCustomerVisibility.ReportBundleID = ReportBundle.ID)
INNER JOIN ReportGroupType ON ReportBundleGroup.ReportGroupTypeID = ReportGroupType.ID)
WHERE ReportBundleCustomerVisibility.ReferenceCustomerID = 2303
I also highly suggest against using "SELECT *" in production code or any query you plan on reusing as the table schema can change and possibly effect reports and UI. Explicitly specify the columns instead.
