I need to get this sql query working:
SELECT TOP 15 id, thumb, width, height
FROM (SELECT vPictures.id, vPictures.thumb, vPictureCrops.width, vPictureCrops.height
FROM vPictures INNER JOIN
vPictureCrops ON vPictures.id = vPictureCrops.picid
WHERE (vPictureCrops.width = '602') AND (vPictureCrops.height = '131')
GROUP BY vPictures.id, vPictures.thumb, vPictureCrops.width, vPictureCrops.height) AS derivedtbl_1
WHERE (id NOT IN
(SELECT TOP 0 vPictures_1.id, vPictures_1.datetime, vPictures_1.url, vPictures_1.author, vPictures_1.companyID, vPictures_1.source,
vPictures_1.people, vPictures_1.text, vPictures_1.thumb, vPictures_1.logo, vPictureCrops_1.id AS Expr1, vPictureCrops_1.picid,
vPictureCrops_1.url AS Expr2, vPictureCrops_1.width, vPictureCrops_1.height
FROM vPictures AS vPictures_1 INNER JOIN
vPictureCrops AS vPictureCrops_1 ON vPictures_1.id = vPictureCrops_1.picid))
ORDER BY id DESC
Can you help me?
The error message:
"Only one expression can be specified in the select list when the subquery is not introduced with EXISTS)"
The Where (ID not IN(
The Select must only have one field are the IN can not understand which column you are trying to parse.
Eg from here
USE AdventureWorks2008R2;
GO
SELECT p.FirstName, p.LastName
FROM Person.Person AS p
JOIN Sales.SalesPerson AS sp
ON p.BusinessEntityID = sp.BusinessEntityID
WHERE p.BusinessEntityID IN
(SELECT BusinessEntityID
FROM Sales.SalesPerson
WHERE SalesQuota > 250000);
GO
Not sure what you are trying to achieve with the query anyway, can you explain the usage of the where in clause,
I can see two problems with (id NOT IN (SELECT TOP 0 vPictures_1.id, ...
only when column should be specified in the select statement after IN. For example (id NOT IN (SELECT vPictures_1.id FROM ...
even if you make it just one field vPictures_1.id the condition will always be false because of top 0.

I dont't get it. I changed some of the code. In the WPLEVENT Table are a lot of Events per person. In the Persab-Table are the Persons with their History. Now I need the from the Persab Table just that row wich matches the persab.gltab Date nearest to the WPLEVENT.vdat Date. So all rows from the WPLEVENT, but just the one matching row from the PERSAB-Table.
SELECT
persab.name,
persab.vorname,
vdat,
eventstart,
persab.rc1,
persab.rc2
FROM wplevent
INNER JOIN
persab ON WPLEVENT.PersID = persab.PRIMKEY
INNER JOIN
(SELECT TOP 1 persab.rc1
FROM PERSAB
WHERE persab.gltab <= getdate() --/ Should be wplevent.vdat instead of getdate()
) NewTable ON wplevent.persid = persab.primkey
WHERE
persid ='100458'
ORDER BY vdat DESC
Need to use the MAX() function with the proper syntax by supplying an expression like MAX(persab.rc1). Also need to use GROUP BY for the second column rc2 in the subquery (although it looks like you do not need it). Finally you are missing the ON clause for the final INNER JOIN. I can update the answer to fix the query if you provide that information.
SELECT
Z1PERS.NAME
, Z1PERS.VORNAME
, WPLEVENT.VDat
, WPLEVENT.EventStart
, WPLEVENT.EventStop
, WPLEVENT.PEPGROUP
, Z1SGRP.TXXT
, PERSAB.GLTAB
, Z1PERS.PRIMKEY AS Expr1
, PERSAB.PRIMKEY
FROM
Z1PERS
INNER JOIN
WPLEVENT ON Z1PERS.PRIMKEY = WPLEVENT.PersID
INNER JOIN
Z1SGRP ON WPLEVENT.PEPGROUP = Z1SGRP.GRUPPE
INNER JOIN
(
SELECT MAX(Persab.rc1) --Fixed MAX expression
, persab.rc2
FROM
persab
GROUP BY
persab.rc2 --Need to group on rc2 if you want that column in the query otherwise remove this AND the rc2 column from select list
WHERE
WPLEVENT.PersID = PERSAB.PRIMKEY
AND WPLEVENT.VDat <= PERSAB.GLTAB
) --Missing ON clause for the INNER JOIN here
WHERE z1pers.vorname = 'henning'
Have this COUNT subquery but I can't get the syntax to work .
SELECT products.client_id,
clients.name AS client_name,
cars.vin,
cars.make,
cars.model
(SELECT COUNT(*) FROM manheim_auction_listings AS listings_sub
JOIN products ON
manheim_auction_listings.product_id = products.id
JOIN product_purchases ON
products.current_product_purchase_id = product_purchases.id
WHERE listings_sub.car_id = manheim_auction_listings.car_id AND
listings_sub.id <> manheim_auction_listings.id and
manheim_auction_listings.product_purchase_id =
product_purchases.id) as previous_auction_count
FROM manheim_auction_listings
JOIN cars ON
cars.id = manheim_auction_listings.car_id .....
The (SELECT COUNT(*) will not pass syntax with the JOIN's I Need to get the right count.
You are missing GROUP BY in your inner query.
WHERE listings_sub.car_id = manheim_auction_listings.car_id AND
listings_sub.id <> manheim_auction_listings.id and
manheim_auction_listings.product_purchase_id =
product_purchases.id
GROUP BY <list_of_column(s)>
Also, there are couple more syntax error(s)
You are missing comma , just after cars.model column MUST be separated by ,.
cars.model
(SELECT COUNT(*) FROM manheim_auction_listings AS listings_sub
Is it not possible to use the "as [item] and then use the item variable in the query.
For example:
select c.category as [category],c.orderby as [CatOrder], m.masterno, m.master
,-- select OUT (select count(*) from rentalitem ri with (nolock),
rentalitemstatus ris with (nolock),
rentalstatus rs with (nolock)
where ri.rentalitemid = ris.rentalitemid
and ris.rentalstatusid = rs.rentalstatusid
and ri.masterid = m.masterid
and rs.statustype in ('OUT', 'INTRANSIT', 'ONTRUCK')) as [qtyout]
,-- select OWNED owned=
(select top 1 mwq.qty
from masterwhqty mwq
where mwq.masterid = m.masterid)
, -([owned]-[qtyout]) as [Variance]
from master m
inner join category c on c.categoryid=m.categoryid and c.categoryid=#category
inner join inventorydepartment d on c.inventorydepartment=#department
I cannot seem to use qtyout or owned when calculating variance. How can I do that?
You can also use a table variable and then reference that table variable like you are trying to do above....here's an example from MSDN
USE AdventureWorks2012;
GO
DECLARE #MyTableVar table(
EmpID int NOT NULL,
OldVacationHours int,
NewVacationHours int,
ModifiedDate datetime);
UPDATE TOP (10) HumanResources.Employee
SET VacationHours = VacationHours * 1.25,
ModifiedDate = GETDATE()
OUTPUT inserted.BusinessEntityID,
deleted.VacationHours,
inserted.VacationHours,
inserted.ModifiedDate
INTO #MyTableVar;
--Display the result set of the table variable.
SELECT EmpID, OldVacationHours, NewVacationHours, ModifiedDate
FROM #MyTableVar;
GO
--Display the result set of the table.
SELECT TOP (10) BusinessEntityID, VacationHours, ModifiedDate
FROM HumanResources.Employee;
GO
need to move your calculated fields into a subquery, and then use them by their alias in the outer query.
select subquery.*, -([owned]-[qtyout]) as [Variance]
from
(
select c.category as [category],c.orderby as [CatOrder], m.masterno, m.master
,-- select OUT (select count(*) from rentalitem ri with (nolock),
rentalitemstatus ris with (nolock),
rentalstatus rs with (nolock)
where ri.rentalitemid = ris.rentalitemid
and ris.rentalstatusid = rs.rentalstatusid
and ri.masterid = m.masterid
and rs.statustype in ('OUT', 'INTRANSIT', 'ONTRUCK')) as [qtyout]
,-- select OWNED owned=
(select top 1 mwq.qty
from masterwhqty mwq
where mwq.masterid = m.masterid) as [owned]
from master m
inner join category c on c.categoryid=m.categoryid and c.categoryid=#category
inner join inventorydepartment d on c.inventorydepartment=#department
) as subquery
YOu need to use a subquery:
select t.*,
([owned]-[qtyout]) as [Variance]
from (<something like your query here
) t
You query, even without the comments, doesn't quite make sense (select OUT (select . . . for isntance). But, the answer to your question is to define the base variables in a subquery or CTE and then subsequently use them.
And, you are calling the difference "variance". Just so you know, you are redefining the statistical meaning of the term (http://en.wikipedia.org/wiki/Variance), which is based on the squares of the differences.
I'm trying to make a query to retrieve the region which got the most sales for sweet products. 'grupo_produto' is the product type, and 'regiao' is the region. So I got this query:
SELECT TOP 1 r.nm_regiao, (SELECT COUNT(*)
FROM Dw_Empresa
WHERE grupo_produto='1' AND
cod_regiao = d.cod_regiao) as total
FROM Dw_Empresa d
INNER JOIN tb_regiao r ON r.cod_regiao = d.cod_regiao ORDER BY total DESC
Then when i run the query, MS-Access asks for the "total" parameter. Why it doesn't consider the newly created 'column' I made in the select clause?
Thanks in advance!
Old Question I know, but it may help someone knowing than while you cant order by aliases, you can order by column index. For example, this will work without error :
SELECT
firstColumn,
IIF(secondColumn = '', thirdColumn, secondColumn) As yourAlias
FROM
yourTable
ORDER BY
2 ASC
The results would then be ordered by the values found in the second column wich is the Alias "yourAlias".
Aliases are only usable in the query output. You can't use them in other parts of the query. Unfortunately, you'll have to copy and paste the entire subquery to make it work.
You can do it like this
select * from(
select a + b as c, * from table)
order by c
Access has some differences compared to Sql Server.
Why it doesn't consider the newly
created 'column' I made in the select
clause?
Because Access (ACE/Jet) is not compliant with the SQL-92 Standard.
Consider this example, which is valid SQL-92:
SELECT a AS x, c - b AS y
FROM MyTable
ORDER
BY x, y;
In fact, x and y the only valid elements in the ORDER BY clause because all others are out of scope (ordinal numbers of columns in the SELECT clause are valid though their use id deprecated).
However, Access chokes on the above syntax. The equivalent Access syntax is this:
SELECT a AS x, c - b AS y
FROM MyTable
ORDER
BY a, c - b;
However, I understand from #Remou's comments that a subquery in the ORDER BY clause is invalid in Access.
Try using a subquery and order the results in an outer query.
SELECT TOP 1 * FROM
(
SELECT
r.nm_regiao,
(SELECT COUNT(*)
FROM Dw_Empresa
WHERE grupo_produto='1' AND cod_regiao = d.cod_regiao) as total
FROM Dw_Empresa d
INNER JOIN tb_regiao r ON r.cod_regiao = d.cod_regiao
) T1
ORDER BY total DESC
(Not tested.)
How about:
SELECT TOP 1 r.nm_regiao
FROM (SELECT Dw_Empresa.cod_regiao,
Count(Dw_Empresa.cod_regiao) AS CountOfcod_regiao
FROM Dw_Empresa
WHERE Dw_Empresa.[grupo_produto]='1'
GROUP BY Dw_Empresa.cod_regiao
ORDER BY Count(Dw_Empresa.cod_regiao) DESC) d
INNER JOIN tb_regiao AS r
ON d.cod_regiao = r.cod_regiao
I suggest using an intermediate query.
SELECT r.nm_regiao, d.grupo_produto, COUNT(*) AS total
FROM Dw_Empresa d INNER JOIN tb_regiao r ON r.cod_regiao = d.cod_regiao
GROUP BY r.nm_regiao, d.grupo_produto;
If you call that GroupTotalsByRegion, you can then do:
SELECT TOP 1 nm_regiao, total FROM GroupTotalsByRegion
WHERE grupo_produto = '1' ORDER BY total DESC
You may think it's extra work to create the intermediate query (and, in a sense, it is), but you will also find that many of your other queries will be based off of GroupTotalsByRegion. You want to avoid repeating that logic in many other queries. By keeping it in one view, you provide a simplified route to answering many other questions.
How about use:
WITH xx AS
(
SELECT TOP 1 r.nm_regiao, (SELECT COUNT(*)
FROM Dw_Empresa
WHERE grupo_produto='1' AND
cod_regiao = d.cod_regiao) as total
FROM Dw_Empresa d
INNER JOIN tb_regiao r ON r.cod_regiao = d.cod_regiao
) SELECT * FROM xx ORDER BY total
I'm having this Mysql query, It works:
SELECT
nom
,prenom
,(SELECT GROUP_CONCAT(category_en) FROM
(SELECT DISTINCT category_en FROM categories c WHERE id IN
(SELECT DISTINCT category_id FROM m3allems_to_categories m2c WHERE m3allem_id = 37)
) cS
) categories
,(SELECT GROUP_CONCAT(area_en) FROM
(SELECT DISTINCT area_en FROM areas c WHERE id IN
(SELECT DISTINCT area_id FROM m3allems_to_areas m2a WHERE m3allem_id = 37)
) aSq
) areas
FROM m3allems m
WHERE m.id = 37
The result is:
nom prenom categories areas
Man Multi Carpentry,Paint,Walls Beirut,Baalbak,Saida
It works correclty, but only when i hardcode into the query the id that I want (37).
I want it to work for all entries in the m3allem table, so I try this:
SELECT
nom
,prenom
,(SELECT GROUP_CONCAT(category_en) FROM
(SELECT DISTINCT category_en FROM categories c WHERE id IN
(SELECT DISTINCT category_id FROM m3allems_to_categories m2c WHERE m3allem_id = m.id)
) cS
) categories
,(SELECT GROUP_CONCAT(area_en) FROM
(SELECT DISTINCT area_en FROM areas c WHERE id IN
(SELECT DISTINCT area_id FROM m3allems_to_areas m2a WHERE m3allem_id = m.id)
) aSq
) areas
FROM m3allems m
And I get an error:
Unknown column 'm.id' in 'where
clause'
Why?
From the MySql manual:
13.2.8.7. Correlated Subqueries
[...]
Scoping rule: MySQL evaluates from inside to outside.
So... do this not work when the subquery is in a SELECT section? I did not read anything about that.
Does anyone know? What should I do? It took me a long time to build this query... I know it's a monster query but it gets what I want in a single query, and I am so close to getting it to work!
Can anyone help?
You can only correlate one level deep.
Use:
SELECT m.nom,
m.prenom,
x.categories,
y.areas
FROM m3allens m
LEFT JOIN (SELECT m2c.m3allem_id,
GROUP_CONCAT(DISTINCT c.category_en) AS categories
FROM CATEGORIES c
JOIN m3allems_to_categories m2c ON m2c.category_id = c.id
GROUP BY m2c.m3allem_id) x ON x.m3allem_id = m.id
LEFT JOIN (SELECT m2a.m3allem_id,
GROUP_CONCAT(DISTINCT a.area_en) AS areas
FROM AREAS a
JOIN m3allems_to_areas m2a ON m2a.area_id = a.id
GROUP BY m2a.m3allem_id) y ON y.m3allem_id = m.id
WHERE m.id = ?
The reason for the error is that in the subquery m is not defined. It is defined later in the outer query.
