SELECT *
FROM visitdetails vd
LEFT JOIN
(SELECT MAX(id) AS id, VisitID
FROM claimfilelist GROUP BY VisitID) cf ON cf.visitid = vd.Id
LEFT JOIN claimfilelist cf1 ON cf1.id = cf.id
I have this SQL query. How can I convert it to HQL?
The HQL-documentation says that subqueries are only allowed in SELECT and WHERE. So, my first step is to move the subquery to the WHERE-clause:
SELECT *
FROM visitdetails vd
LEFT JOIN claimfilelist cf ON cf.visitid = vd.id
WHERE cf.id IS NULL OR cf.id = (
SELECT max(cfInner.id)
FROM claimfilelist cfInner
WHERE cfInner.visitId = vd.id
)
Depending on your Hibernate - version you might need to change the joins. I am not sure if the query works, but you could give the approach a try.

I have this query:

WHERE tag < SYSDATE
GROUP BY lfdnr
) t1
ON wkurse.lfdnr = t1.lfdnr AND wkurse.Tag = t1.maxTag

FROM vertragspos
GROUP BY vertrag_ID
) s ON vertragskopf.id = s.vertrag_id
But I always get an error on line 21 Pos 145:
ORA-00904 WKURSE.KURS invalid identifier
The WKURSE table is supposed be joined already above, but why do I still get error?
How can I do join with all these tables?
I need to join all these tables:
Mitarbeiter, Vertragspos, vertrag_ek_vk_zuord, wkurse, fremdwaehrung, vertragskopf.
What is the right syntax? I'm using SQL Tool 1,8 b38
Thank you.
Because LEFT JOIN is executed on entire dataset, and not in row-by-row manner. So there's no wkurse.kurs available in the execution context of subquery. Since you join that tables, you can place the calculation in the top-most select statement.
EDIT:
After you edited the statement, it became clear where does vertragskopf.zahlintervall came from. But I don't know where are you going to use calculated vertragswert (now it is absent in the query), so I've put it in the result. As I'm not a SQL parser and have no idea of your tables, so I cannot check the code, but calculation now can be resolved (all the values are available in calculation context).
SELECT DISTINCT mitarbeiter.mitarbnr, mitarbeiter.login, mitarbeiter.name1, mitarbeiter.name2, s.amount / Decode (vertragskopf.zahlintervall, 1,1,2,2,3,3,4,6,5,12,1) / wkurse.kurs) vertragswert
FROM vertragspos
left join vertrag_ek_vk_zuord ON vertragspos.id = vertrag_ek_vk_zuord.ek_vertragspos_id
left join mitarbeiter ON vertrag_ek_vk_zuord.anlage_mitarbnr = mitarbeiter.mitarbnr
left join vertragskopf ON vertragskopf.id = vertragspos.vertrag_id
left join (
SELECT wkurse.*, fremdwaehrung.wsymbol
FROM wkurse
INNER join (
SELECT lfdnr, Max(tag) AS maxTag
FROM wkurse
WHERE tag < SYSDATE
GROUP BY lfdnr
) t1
ON wkurse.lfdnr = t1.lfdnr AND wkurse.Tag = t1.maxTag
INNER JOIN fremdwaehrung ON wkurse.lfdnr = fremdwaehrung.lfdnr
) wkurse ON vertragskopf.blfdwaehrung = wkurse.lfdnr
left join (
SELECT vertrag_ID, Sum (preis) preis, Sum (menge) menge, Sum (preis * menge) as amount
FROM vertragspos
GROUP BY vertrag_ID
) s ON vertragskopf.id = s.vertrag_id
Rewriting the code using WITH clause makes it much clearer than select from select.
Also get the rate on last day before today in oracle is as simple as
select wkurse.lfdnr
, max(wkurse.kurs) keep (dense_rank first order by wkurse.tag desc) as rate
from wkurse
where tag < sysdate
group by wkurse.lfdnr
One option is a lateral join:
left join lateral
(SELECT vertrag_ID, Sum(preis) as preis, Sum(menge) as menge,
Sum (preis * menge / Decode (vertragskopf.zahlintervall, 1,1,2,2,3,3,4,6,5,12,1) / wkurse.kurs) vertragswert
FROM vertragspos
GROUP BY vertrag_ID
) s
ON vertragskopf.id = s.vertrag_id
Anybody know why this isn't working? I'm getting: ERROR: syntax error at or near "most_recent"
with most_recent as (SELECT MAX(public."Master_playlist".updated_at)
FROM public."Master_playlist")
SELECT * from public."Playlist"
JOIN public."Master_playlist_playlist" on public."Playlist".id = public."Master_playlist_playlist".playlist_id
JOIN public."Master_playlist" on public."Master_playlist_playlist".master_playlist_id = public."Master_playlist".id
WHERE public."Master_playlist".updated_at = most_recent;
Supposed to be getting the most recent date from Master_playlist and then using that to select a Master_playlist to join the inner query with
Thanks! HM
The with clause creates a derived table, which you need select from, using a join or a subquery. You also need to alias the column so you can refer to it afterwards, as in:
with most_recent as (
SELECT MAX(updated_at) max_updated_at
FROM public."Master_playlist"
)
SELECT *
from public."Playlist"
JOIN public."Master_playlist_playlist"
on public."Playlist".id = public."Master_playlist_playlist".playlist_id
JOIN public."Master_playlist"
on public."Master_playlist_playlist".master_playlist_id = public."Master_playlist".id
WHERE public."Master_playlist".updated_at = (SELECT max_updated_at FROM most_recent)
But here, it looks like it is simpler to use a row-limiting query:
select ...
from (
select *
from public."Master_playlist"
order by updated_at desc
limit 1
) mp
inner join public."Master_playlist_playlist" mpp
on mpp.master_playlist_id = mp.id
inner join public."Playlist" p
on p.id = mpp.playlist_id

Apache phoenix is not supporting the keyword INTERSECT. Can somebody please help me to correct above query without using INTERSECT?
I think there are multiple ways you can do this:
Join Method
select * from ((query1 inner join query2 on column_names) inner join query3 on column_names)
Exists Method
(query1 where exists (query2 where exists (query3)) )
In Method
(query1 where column_name in (query2 where column_name in (query3)) )

and http://phoenix.apache.org/subqueries.html
Although I would use the exists/in over the join since if these queries return huge data then you might have to optimize your queries using this:

The problem is the second query, the "recursive one" is getting the data I expect since I can't do the LEFT JOINs like in the first query. (At least to my understanding).
If I remove the fetching of the data that requires the LEFT (Outer) JOINs then the recursion works perfectly. My problem is I need both. Is there a way I can accomplish this?
Per http://msdn.microsoft.com/en-us/library/ms175972.aspx you can not have a left/right/outer join in a recursive CTE.
For a recursive CTE you can't use a subquery either so I sugest following this example.
They use two CTE's. The first is not recursive and does the left join to get the data it needs. The second CTE is recursive and inner joins on the first CTE. Since CTE1 is not recursive it can left join and supply default values for the missing rows and is guarenteed to work in the inner join.
However, you can also duplicate a left join with a union and subselect though it isn't really useful normally but it is interesting.
In that case, you would keep your first statement how it is. It will match all rows that join successfully.
Then UNION that query with another query that removes the join, but has a
NOT EXISTS(SELECT 1 FROM MISSING_ROWS_TABLE WHERE MAIN_TABLE.JOIN_CONDITION = MISSING_ROWS_TABLE.JOIN_CONDITION)
This gets all the rows that failed the previous join condition in query 1. You can replace the colmuns you would get from MISSING_ROWS_TABLE with NULL. I had to do this once using a coding framework that didn't support outer joins. Since recursive CTE's don't allow subqueries you have to use the first solution.
I was trying to join 3 tables - CurrentProducts, SalesInvoice and SalesInvoiceDetail. SalesInvoiceDetail contains FK/foreign key to the other two tables and some other columns. The first query is ok but the second is not. My question comes at the end of the code.
Right
select *
from CurrentProducts inner join
(dbo.SalesInvoiceDetail inner join dbo.SalesInvoice
on dbo.SalesInvoiceDetail.InvoiceID = dbo.SalesInvoice.InvoiceID
)
on dbo.SalesInvoiceDetail.ProductID = dbo.CurrentProducts.ProductID
Wrong
select *
from CurrentProducts inner join
(select * from
dbo.SalesInvoiceDetail inner join dbo.SalesInvoice
on dbo.SalesInvoiceDetail.InvoiceID = dbo.SalesInvoice.InvoiceID
)
on dbo.SalesInvoiceDetail.ProductID = dbo.CurrentProducts.ProductID
error - Incorrect syntax near the keyword 'on'.
Why is the second query wrong ? Isn't it conceptually the same as the first one ? That is inside join makes a result set. We select * the result set and then join this result set to CurrentProducts ?
The first query is a "plain" join expressed with an older syntax. It can be rewritten as:
select
*
from
CurrentProducts
inner join dbo.SalesInvoiceDetail
on dbo.SalesInvoiceDetail.ProductID = dbo.CurrentProducts.ProductID
inner join dbo.SalesInvoice
on dbo.SalesInvoiceDetail.InvoiceID = dbo.SalesInvoice.InvoiceID
The second query is a join where the second table is a subquery. When you join on a subquery, you must assign an alias to it and use that alias to refer to the columns returned by the subquery:
select
*
from
CurrentProducts
inner join (select *
from dbo.SalesInvoiceDetail
inner join dbo.SalesInvoice
on SalesInvoiceDetail.InvoiceID = SalesInvoice.InvoiceID
) as foo on foo.ProductID = dbo.CurrentProducts.ProductID
You need to alias the inner query. Also, in the first one the parentheses are not needed.
select *
from CurrentProducts inner join
(select * from
dbo.SalesInvoiceDetail inner join dbo.SalesInvoice
on dbo.SalesInvoiceDetail.InvoiceID = dbo.SalesInvoice.InvoiceID
) A
on A.ProductID = dbo.CurrentProducts.ProductID
