Can Derby handle scalar subqueries in SELECT clause? - sql

I'm having trouble getting my query working. Could someone cast an experienced eye on it please? The table structure is simple (2 one-to-many relationships). The query is trying to work out for each sign, how many contributions there are at each unique "PositionLocation".
Sign <- Signifier (f_key sign_oid) <- Contribution (f_key signifier_oid)
I'm getting the following error:
Error: An ON clause associated with a JOIN operator is not valid.
SQLState: 42972
ErrorCode: -1
My query is:
select s.NAME, c.POSITIONLOCATION, count(*) as num_per_locn,
(
select count(*) from APP.CONTRIBUTION c2
inner join APP.SIGNIFIER si2 on si2.OID = c2.SIGNIFIER_OID
inner join APP.SIGN s2 on s2.OID = si2.SIGN_OID
and s2.OID = s.OID
) as num_per_sign
from APP.CONTRIBUTION c
inner join APP.SIGNIFIER si on si.OID = c.SIGNIFIER_OID
inner join APP.SIGN s on s.OID = si.SIGN_OID
group by s.NAME, c.POSITIONLOCATION

How to fix SQL query to Left Join a subquery with Where clause?

I'm new to SQL and I'm not certain why I am getting this error. I am trying to left join a sub-query to another query in sql developer.
This is the first query,
SELECT DISTINCT
tl.species,
ag.age
FROM
age_list ag,
tree_list tl
WHERE
ag.tree_id = tl.tree_id
And then the sub-query I would like to left join where the tree_id = tree_number is,
SELECT DISTINCT
sl.tree_spon,
sl.tree_number
FROM spon_list sl
WHERE
sl.tree_spon < 10
When trying to do this I've tried to use,
SELECT DISTINCT
tl.species,
ag.age,
q1.tree_spon
FROM
age_list ag,
tree_list tl
LEFT OUTER JOIN (SELECT DISTINCT
sl.tree_spon,
sl.tree_number
FROM spon_list sl
WHERE sl.tree_spon < 10) q1 on q1.tree_number = tree_list.tree_id
WHERE
ag.tree_id = tl.tree_id
Whatever I change in terms of the alias' for the columns and tables I always get the error, "ORA-00904: invalid identifier error", and that "tree_list.tree_id is invalid identifier", though separately the queries run fine.
Can anyone help, is it an issue with both queries joining on the tl.tree_id?
You can use the ANSI join syntax throughout (rather than mixing in legacy comma joins), joining on ag.tree_id = sl.tree_number (or tl.tree_id = sl.tree_number but they're both equal given the previous join) and putting the filter on sl.tree_spon < 10 into the ON clause as well:
SELECT DISTINCT
tl.species,
ag.age,
sl.tree_spon,
sl.tree_number
FROM age_list ag
INNER JOIN tree_list tl
ON (ag.tree_id = tl.tree_id)
LEFT OUTER JOIN spon_list sl
ON (ag.tree_id = sl.tree_number AND sl.tree_spon < 10)
Change tree_list.tree_id to tl.tree_id

correlated sub query

Trying to show customers' vehicles who had an invoice raised in the past 30 days.
I tried this:
select C.*, V.*
from CAR_OWNERSHIP O
join VEHICLE V on v.VEH_ID = O.VEH_ID
join CUSTOMER C on C.CUS_ID = O.CUS_ID
where exists (select null
from INVOICE I
where I.INV_ID = O.INV_ID and
I.INV_DATE >= date() - 30);
Im getting "syntax error in FROM clause"
I have quickly tried a query in access and I get the same error you get but when I change the JOIN to a specific join like LEFT OUTER JOIN or INNER JOIN then that error goes away but it is replaced with another
Syntax error (missing operator) in query expression in
I researched that and found this post which indicates that access requires parentheses when using more than one join
select *
from (CAR_OWNERSHIP O
left outer join CUSTOMER C on C.CUS_ID = O.Cus_ID)
left outer join VEHICLE V on v.VEH_ID = O.VEH_ID
where exists (select null
from INVOICE I
where I.INV_ID = O.INV_ID and
I.INV_DATE >= date() - 30);
I do hope this helps

Subquery with multiple joins involved

Still trying to get used to writing queries and I've ran into a problem.
Select count(region)
where (regionTable.A=1) in
(
select jxn.id, count(jxn.id) as counts, regionTable.A
from jxn inner join
V on jxn.id = V.id inner join
regionTable on v.regionID = regionTable.regionID
group by jxn.id, regionTable.A
)
The inner query gives an ID number in one column, the amount of times they appear in the table, and then a bit attribute if they are in region A. The outer query works but the error I get is incorrect syntax near the keyword IN. Of the inner query, I would like a number of how many of them are in region A
You must specify table name in query before where
Select count(region)
from table
where (regionTable.A=1) in
And you must choose one of them.
where regionTable.A = 1
or
where regionTable.A in (..)
Your query has several syntax errors. Based on your comments, I think there is no need for a subquery and you want this:
select jxn.id, count(jxn.id) as counts, regionTable.A
from jxn inner join
V on jxn.id = V.id inner join
regionTable on v.regionID = regionTable.regionID
where regionTable.A = 1
group by jxn.id, regionTable.A
which can be further simplified to:
select jxn.id, count(jxn.id) as counts
, 1 as A --- you can even omit this line
from jxn inner join
V on jxn.id = V.id inner join
regionTable on v.regionID = regionTable.regionID
where regionTable.A = 1
group by jxn.id
You are getting the error because of this line:
where (regionTable.A=1)
You cannot specify a condition in a where in clause, it should only be column name
Something like this may be what you want:
SELECT COUNT(*)
FROM
(
select jxn.id, count(jxn.id) as counts, regionTable.A
from
jxn inner join
V on jxn.id = V.id inner join
regionTable on v.regionID = regionTable.regionID
group by jxn.id, regionTable.A
) sq
WHERE sq.a = 1

Left Join on Same table - Not recognizing nested SELECT statement

I am trying to pull two different values based on different criteria from the same table and in my Left Join of the same table it is not recognizing the SELECT statement.
The error is as follows:
Dynamic SQL Error
SQL error code = -104
Token unknown - line 7, char -1
SELECT.
The SQL Statement:
SELECT
b.dept,b.typ,c.brand,c.style,c.ext,c.description,
max(c.price),max(c.last_cost),sum(c.quan) "TOTAL INV",D.QUAN "WEB INV"
FROM
invt c
left outer join (
SELECT dept,typ,brand,style,ext,description,sum(quan) as d.quan
FROM invt WHERE store in ('997')
group by dept,typ,brand,style,ext,description) d
on (b.store = d.store and b.style = d.style and b.brand = d.brand)
LEFT OUTER JOIN
sku b
on c.style = b.style and c.brand = b.brand
where c.quan <> 0 or c.ord <> 0
GROUP BY
b.dept,b.typ,c.brand,c.style,c.ext,c.description
Try changing this line:
SELECT dept,typ,brand,style,ext,description,sum(quan) as d.quan
to this:
SELECT store,dept,typ,brand,style,ext,description,sum(quan) as quan
You do not need the d alias here.
UPDATE:
As #Jeremy Holovacs mentioned, you also seem to be using d.store for your join but it does not exist in your subquery.

What could create a syntax error if you take a SQL query and perform an UNION with itself?

I have this strange error in SQL Server 2005 where I take a working query, add the UNION keyword below it and then copy the query again. In my opinion, this should always be working, but it is not. I get the message 'Incorrect syntax near the keyword 'union'.
What could create this problem ?
To be more specific, here is the complete query :
select distinct deliveries.id, orders.id, 20 + sum(orders.mass1) as allowed_duration
from features_resources
inner join features on features.id = featureid
inner join orders on orders.id = features_resources.resourceid
inner join orderinformations on orders.id = orderinformations.orderid
inner join deliveries on orderinformations.deliveryid = deliveries.id
where features.name = 'O_FRAIS'
and (deliveries.ID IN
(SELECT ID
FROM dbo.DeliveriesInExportedSchedule))
group by deliveries.id, features.name ,orders.id order by deliveries.id
union
select distinct deliveries.id, orders.id, 20 + sum(orders.mass1) as allowed_duration
from features_resources
inner join features on features.id = featureid
inner join orders on orders.id = features_resources.resourceid
inner join orderinformations on orders.id = orderinformations.orderid
inner join deliveries on orderinformations.deliveryid = deliveries.id
where features.name = 'O_FRAIS'
and (deliveries.ID IN
(SELECT ID
FROM dbo.DeliveriesInExportedSchedule))
group by deliveries.id, features.name ,orders.id order by deliveries.id
I have tried to reproduce the error on a smaller query, by starting from a simple query and adding features one by one (inner join, nested queryes, group by, sum,....) but failed to reproduce the error again.
Any idea ?
It is actually the order by deliveries.id in the top half that causes the problem.
The order by needs to apply to the whole query.
Example Syntax
SELECT v1.number
FROM master.dbo.spt_values v1
WHERE v1.number > 2000
UNION
SELECT v2.number
FROM master.dbo.spt_values v2
WHERE v2.number < 10
ORDER BY v1.number
Try putting the individual SELECTs in parentheses:
(SELECT ... )
UNION
(SELECT ... )
The way you have it now, the second WHERE and GROUP BY clauses are ambiguous - should that apply to the SELECT, or to the UNION? I don't have any way to tell, and neither has your DB server.
