The table machineslocation_loc has createddate column in it. Whenever I call it says "missing FROM-clause entry for table "machineslocation_loc" but x column is coming from that table. I tried ml.createddate and machineslocation_loc.createddate. There are createddate column in other tables too
Try calling using the alias of your subquery, and please avoid * , call the name by his name
SELECT x, tableWithCount.createddate, count_ FROM
(SELECT x, ml.*,ma.*,sh.*,ph.*,ar.*,pa.*, count(*)
OVER
(PARTITION BY
x
) AS count_
FROM machineslocation_loc AS ml
JOIN m AS ma ON ma.mid= ml.mid
JOIN sh AS sh ON sh.shid = ma.shid
JOIN ph AS ph ON ph.phid = sh.phid
JOIN ar AS ar ON ar.arid = ph.arid
JOIN pn AS pa ON pa.pnid = ar.pnid
AND x LIKE '%705N%') as tableWithCount
make sure that not exist another column named createddate from the other tables inside the subquery
UPDATE:but you do not use the rest of the columns on the main query, so remove the * and only put the columns that you need, for example:
SELECT x, tableWithCount.mlcreateddate, count_ FROM
(SELECT x,ml.createddate mlcreateddate, count(*)
OVER
(PARTITION BY
x
) AS count_
FROM machineslocation_loc AS ml
JOIN m AS ma ON ma.mid= ml.mid
JOIN sh AS sh ON sh.shid = ma.shid
JOIN ph AS ph ON ph.phid = sh.phid
JOIN ar AS ar ON ar.arid = ph.arid
JOIN pn AS pa ON pa.pnid = ar.pnid
AND x LIKE '%705N%') as tableWithCount

Lets assume we have the following table1:
1 2 3
a x m
a y m
b z m
I want to do an inner join on the table
INNER JOIN tabel2 ON table1.2 = table2.2
Somehow like this, but additional a condition that the value of table1.1 not unique. Thus on table1.1 = b no inner join will occure in this example.
What is the best way to achieve this?
Using a an aggregate in a sub query is how I would do it
SELECT *
FROM table1
JOIN table2
ON table1."2" = table2."2"
JOIN (
SELECT "1"
FROM table1
GROUP BY "1"
HAVING COUNT(*) > 1
) AS sub_q
ON sub_q."1" = table1."1";
Another option might be a cte or temporary table to hold the rows you're joining on
WITH _cte AS
(
SELECT "1"
FROM table1
GROUP BY "1"
HAVING COUNT(*) > 1
)
SELECT *
FROM table1
JOIN table2
ON table1."2" = table2."2"
JOIN _cte AS cte
ON cte."1" = table1."1";
temp table:
CREATE TEMPORARY TABLE _tab
(
"1" varchar
);
INSERT INTO _tab
SELECT "1"
FROM table1
GROUP BY "1"
HAVING COUNT(*) > 1;
SELECT *
FROM table1
JOIN table2
ON table1."2" = table2."2"
JOIN _tab AS tab
ON tab."1" = table1."1";

If I add new event_event or new product_product I'll get a new definition of row_number in my view, then the column ID of my view is not stable.
at least you can't use row_number as Id of the view,
If you insist to use row_number, you can use the Order By "creation DATE" by this way all new records will be as last lines in the view and this will not change the correspondency between ID (row_number) and other columns.
Hope that helps !
Very likely the execution plan of your query depends on the columns you select. Compare the execution plans!
Your id is generated using the row_number window function. Now window functions are executed before the ORDER BY clause, so the order will depend on the execution plan and hence on the columns you select.
Using row_number without an explicit ordering doesn't make any sense.
To fix that, don't use
row_number() OVER ()
but
row_number() OVER (ORDER BY e.id, pt.categ_id, p.id)
so that you have a reliable ordering.
In addition, you should omit the ORDER BY clause at the end.
I have a following script to get the total unit but it gives me an error
Cannot perform an aggregate function on an expression containing an aggregate or a subquery.
Do I need to calculate SUM(ta.Qty) outside the main table?
SELECT
ta.ProductName
, SUM(ta.Total)
, SUM(SUM(ta.Qty) * ta.Unit)
FROM
tableA tA
INNER JOIN
tableB tB on tA.ID = tb.TableAID
INNER JOIN
tableC tc on ta.ID = tc.TableAID
INNER JOIN
tableD td on td.ID = tb.TableBID
GROUP BY

Here is a query in the AdventureWorks database that produces the same error (but might make some sense):
SELECT v.Name AS Vendor, SUM(SUM(p.ListPrice*d.OrderQty)+h.Freight)
FROM Production.Product p
INNER JOIN Purchasing.PurchaseOrderDetail d ON p.ProductID = d.ProductID
INNER JOIN Purchasing.PurchaseOrderHeader h ON h.PurchaseOrderID = d.PurchaseOrderID
INNER JOIN Purchasing.Vendor v ON v.BusinessEntityID = h.VendorID
GROUP BY v.Name
And here are two ways that I could rewrite that query to avoid the error:
SELECT v.Name AS Vendor, SUM(x.TotalAmount+h.Freight)
FROM (
SELECT PurchaseOrderID, SUM(p.ListPrice*d.OrderQty) AS TotalAmount
FROM Production.Product p
INNER JOIN Purchasing.PurchaseOrderDetail d ON p.ProductID = d.ProductID
GROUP BY PurchaseOrderID
) x
INNER JOIN Purchasing.PurchaseOrderHeader h ON h.PurchaseOrderID = x.PurchaseOrderID
INNER JOIN Purchasing.Vendor v ON v.BusinessEntityID = h.VendorID
GROUP BY v.Name
SELECT v.Name AS Vendor, SUM(x.TotalAmount+h.Freight)
FROM Purchasing.PurchaseOrderHeader h
INNER JOIN Purchasing.Vendor v ON v.BusinessEntityID = h.VendorID
CROSS APPLY (
SELECT SUM(p.ListPrice*d.OrderQty) AS TotalAmount
FROM Production.Product p
INNER JOIN Purchasing.PurchaseOrderDetail d ON p.ProductID = d.ProductID
WHERE d.PurchaseOrderID=h.PurchaseOrderID
) x
GROUP BY v.Name
The first query uses derived tables and the second one uses CROSS APPLY.

I'm trying to create a query that searches out all records that share a similar attribute like so:
select * from table_A
where fullname like in (select firstname from employees where X)
Only thing is that this is just my pseudo code, I actually am sorting through many tables so the real query I have currently looks something like:
select * from devices
where devicename like in (select X from X1 where T in (select T from T1 where Y in (select Y from Y1 where Z in (select Z from Z1 where AreaName = '74';
I'm trying to use the join command but very confused on how to apply it to this situation.
Try:
SELECT d.*
FROM devices d
INNER JOIN X1 ON d.devicename like '%'||x1.X||'%'
INNER JOIN T1 ON x1.T = T1.T
INNER JOIN Y1 ON T1.Y = Y1.Y
INNER JOIN Z1 ON Y1.Z = Z1.Z
WHERE Z1.AreaName = '74'
Here you go ....
SELECT D.*
from Devices D
inner join X1 X on D.devicename like X.X
inner join T1 T on T.T = X.T
inner join Y1 Y on Y.Y = T.Y
inner join Z1 Z on Y.Z = Z1.Z AND Z.Areaname = '74';
Okay, i give you the second query with Join syntax (well, i try to):
select * from Z1 Z1_1
JOIN Y1 Y_1 ON Y_1.Z=Z1_1.Z
JOIN T1 ON T1.Y=Y_1.Y
JOIN X1 X1_2 ON X1_2.T=T1.T
JOIN devices d ON d.devicename=X1_2.X
where Z1_1.AreaName = '74';
Try this:
SELECT d.*
FROM devices d
INNER JOIN X1 ON d.`like` = x1.X
INNER JOIN T1 ON x1.T = T1.T
INNER JOIN Y1 ON T1.Y = Y1.Y
INNER JOIN Z1 ON Y1.Z = Z1.Z
WHERE Z1.AreaName = '74'
The "join" command runs a cross product of the two tables and then selects only the tuples/rows where the common column names have the same values.
So, for your query:
select * from table_A
where fullname like in (select firstname from employees where X)
would be:
select * from table_A
left join employees
on table_A.fullname = employees.firstname
where X
