I am trying to convert a query to an equal orm statement in sqlalchemy and geoalchemy2. I am struggeling how to get the reference for p1.geom into the subquery in the not exists clause.
SELECT p1.geom FROM polygons as p1
WHERE p1.column1 = 'something' AND NOT EXISTS(
SELECT 1 FROM polygons AS p2
WHERE p2.column2 = 'something else' AND ST_Intersects(p1.geom, p2.geom)
)
I already tried around a bit but the closest i got was something like this:
p1 = self._session.query(polygons.geom).filter_by(column1='something').subquery()
p2 = ~self._session.query(polygons.geom).filter(polygons.column2 == 'something else')\
.filter(polygons.geom.intersects(p1.c.geom)).exists()
result = self._session.query(polygons.geom)\
.filter_by(column1='something')\
.filter(p2)
What i got from it:
SELECT polygons.geom FROM polygons
WHERE polygons.column1 = 'something' AND NOT (EXISTS (
SELECT 1 FROM (
SELECT polygons.geom AS geom FROM polygons
WHERE polygons.column1 = 'something') AS anon_1
WHERE polygons.column2 = 'something else' AND (polygons.geom && anon_1.geom)))
Any ideas that could help?

I have a query and am using left joins. I have the left join clause as follows:
left outer join ( select pup.brokerage_code, pcz.zip, count (pup.aggregate_id) as VerifiedAgentCount
from partner_user_profiles pup
join partner_user_roles pure on pure.user_profile_id = pup.id
join profile_coverage_zips pcz on pcz.profile_id = pup.id
where lower(pure.role) = 'agent'
and pup.verification_status like 'Verified%'
group by pup.brokerage_code, pcz.zip) vac on vac.brokerage_code = b.brokerage_code and pcz.zip = bcz.zip
However I am getting the error message saying that I am missing the FROM entry clause for "pcz" however I aliased the table in the join clause so I am not sure what is wrong.
You have defined the table alias pcz within the sub-select however the alias no longer exists when the outside the sub-select. At the point you have used it the appropriate alias is the one for the entire sub-select, in this case vac. So: vac.zip = = bcz.zip
left outer join ( select pup.brokerage_code, pcz.zip, count (pup.aggregate_id) as VerifiedAgentCount
from partner_user_profiles pup
join partner_user_roles pure on pure.user_profile_id = pup.id
join profile_coverage_zips pcz on pcz.profile_id = pup.id
where lower(pure.role) = 'agent'
and pup.verification_status like 'Verified%'
group by pup.brokerage_code, pcz.zip
) vac on vac.brokerage_code = b.brokerage_code
and vac.zip = bcz.zip
I need to count how many records in the tableA are not in the tableA, how to do this with LINQ?
with SQL I do the following way
select count(*) as total from produtoitemgrade g
where g.id not in (select idprodutograde from produtoestoque where idProduto = 12)
and g.idProduto = 12
my linq code so far.
var temp = (from a in Produtoitemgrades
join b in Produtoestoques on a.IdUnico equals b.IdUnicoGrade into g1
where g1.Count(y => y.IdProduto == 12)>0 && !g1.Any()
select a).ToList();
I tried to follow that example LINQ get rows from a table that don't exist in another table when using group by?
but an error occurs when running, how can I do this?
Thanks!
Your query should looks like the following, if you want to have the same SQL execution plan:
var query =
from a in Produtoitemgrades
where !Produtoestoques.Where(b => a.IdUnico == b.IdUnicoGrade && b.idProduto == 12).Any()
&& a.idProduto == 12
select a;
var result = query.Count();
I have the following query:
var newsItems = tree.SelectNodes()
.Types(pageTypesArray)
.Path(path)
.OrderBy(orderBy)
.CombineWithDefaultCulture(false)
.Page(page, count)
.OnCurrentSite()
.NestingLevel(-1)
.Culture(CurrentDocument.DocumentCulture)
.InCategories(categories)
.TopN(topN)
.Where("ListableDocumentImage is not null AND ListableDocumentImage != ''")
.Columns(columns);
Which translates like so:
WITH AllData AS
(
SELECT TOP 6 * for brevity, ROW_NUMBER() OVER (ORDER BY [NewsOccurrenceDate] DESC) AS [CMS_RN]
FROM View_CMS_Tree_Joined AS V WITH (NOLOCK, NOEXPAND) INNER JOIN SOS_News AS C WITH (NOLOCK) ON [V].[DocumentForeignKeyValue] =
[C].[NewsID] AND V.ClassName = N'News' LEFT OUTER JOIN COM_SKU AS S WITH (NOLOCK) ON [V].[NodeSKUID] = [S].[SKUID]
WHERE [NodeSiteID] = #NodeSiteID AND (([DocumentCanBePublished] = 1 AND ([DocumentPublishFrom] IS NULL OR [DocumentPublishFrom] <= #Now)
AND ([DocumentPublishTo] IS NULL OR [DocumentPublishTo] >= #Now))
AND [NodeAliasPath] LIKE #NodeAliasPath AND [DocumentCulture] = #DocumentCulture
**AND 0 = 1)** <<<------------------- WHERE DID THIS COME FROM?????
)
SELECT *, (SELECT COUNT(*) FROM AllData) AS [CMS_TOT]
FROM AllData
WHERE CMS_RN BETWEEN 4 AND 6
ORDER BY CMS_RN
Has anyone ever come across anything like this before? I can't figure out why they're sticking in the AND 0=1 in my where clause.
Properly structuring your document API call will help with this. In your query results, you can see your WHERE condition is not even being added so it does make a difference the order of the methods being called.
For instance:
var newsItems = tree.SelectNodes()
.Types(pageTypesArray)
.Path(path)
.Where("ListableDocumentImage is not null AND ListableDocumentImage != ''")
.TopN(topN)
.OrderBy(orderBy)
.CombineWithDefaultCulture(false)
.Page(page, count)
.NestingLevel(-1)
.Culture(CurrentDocument.DocumentCulture)
.InCategories(categories)
.OnCurrentSite()
.Columns(columns);
SELECT
nzy.NZPYYD
,nzy.NZZSYG
,nzy.NZJRYG
,acn.ANITCD
FROM
ACNTRA acn
LEFT OUTER JOIN NZYTFL nzy
ON (
nzy.NZCNO1 = acn.ANCNO1
AND nzy.NZCNO2 = acn.ANCNO2
AND nzy.NZCNO3 = acn.ANCNO3
AND nzy.NZCNO4 = acn.ANCNO4
AND nzy.NZCNO5 = acn.ANCNO5
AND nzy.NZSLKI = acn.ANSLKI
AND nzy.NZDLTM = ''
)
WHERE
acn.ANDLTM = ''
AND acn.ANTKCD = '1029'
AND nzy.NZTXKB = 1
The problem here is it gives 2 rows result.I want to get one unique row from the result of left outer join .Any help?
If both rows are identical, try
SELECT DISTINCT
nzy.NZPYYD
,nzy.NZZSYG
,nzy.NZJRYG
,acn.ANITCD
If not, you can try to SUM(), CONCAT(), MAX() or whatever the column with different values.
Difficult to be more precise without a sample output.
I am developing a TSQL stored proc using SSMS 2008 and am receiving the above error while generating a CTE. I want to add logic to this SP to return every day, not just the days with data. How do I do this? Here is my SP so far:
ALTER Proc [dbo].[rpt_rd_CensusWithChart]
#program uniqueidentifier = NULL,
#office uniqueidentifier = NULL
AS
DECLARE #a_date datetime
SET #a_date = case when MONTH(GETDATE()) >= 7 THEN '7/1/' + CAST(YEAR(GETDATE()) AS VARCHAR(30))
ELSE '7/1/' + CAST(YEAR(GETDATE())-1 AS VARCHAR(30)) END
if exists (
select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o.id = object_id(N'tempdb..#ENROLLEES')
) DROP TABLE #ENROLLEES;
if exists (
select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o.id = object_id(N'tempdb..#DISCHARGES')
) DROP TABLE #DISCHARGES;
declare #sum_enrollment int
set #sum_enrollment =
(select sum(1)
from enrollment_view A
join enrollment_info_expanded_view C on A.enrollment_id = C.enroll_el_id
where
(#office is NULL OR A.group_profile_id = #office)
AND (#program is NULL OR A.program_info_id = #program)
and (C.pe_end_date IS NULL OR C.pe_end_date > #a_date)
AND C.pe_start_date IS NOT NULL and C.pe_start_date < #a_date)
select
A.program_info_id as [Program code],
A.[program_name],
A.profile_name as Facility,
A.group_profile_id as Facility_code,
A.people_id,
1 as enrollment_id,
C.pe_start_date,
C.pe_end_date,
LEFT(datename(month,(C.pe_start_date)),3) as a_month,
day(C.pe_start_date) as a_day,
#sum_enrollment as sum_enrollment
into #ENROLLEES
from enrollment_view A
join enrollment_info_expanded_view C on A.enrollment_id = C.enroll_el_id
where
(#office is NULL OR A.group_profile_id = #office)
AND (#program is NULL OR A.program_info_id = #program)
and (C.pe_end_date IS NULL OR C.pe_end_date > #a_date)
AND C.pe_start_date IS NOT NULL and C.pe_start_date >= #a_date
;WITH #ENROLLEES AS (
SELECT '7/1/11' AS dt
UNION ALL
SELECT DATEADD(d, 1, pe_start_date) as dt
FROM #ENROLLEES s
WHERE DATEADD(d, 1, pe_start_date) <= '12/1/11')
The most obvious issue (and probably the one that causes the error message too) is the absence of the actual statement to which the last CTE is supposed to pertain. I presume it should be a SELECT statement, one that would combine the result set of the CTE with the data from the #ENROLLEES table.
And that's where another issue emerges.
You see, apart from the fact that a name that starts with a single # is hardly advisable for anything that is not a local temporary table (a CTE is not a table indeed), you've also chosen for your CTE a particular name that already belongs to an existing table (more precisely, to the already mentioned #ENROLLEES temporary table), and the one you are going to pull data from too. You should definitely not use an existing table's name for a CTE, or you will not be able to join it with the CTE due to the name conflict.
It also appears that, based on its code, the last CTE represents an unfinished implementation of the logic you say you want to add to the SP. I can suggest some idea, but before I go on I'd like you to realise that there are actually two different requests in your post. One is about finding the cause of the error message, the other is about code for a new logic. Generally you are probably better off separating such requests into distinct questions, and so you might be in this case as well.
Anyway, here's my suggestion:
build a complete list of dates you want to be accounted for in the result set (that's what the CTE will be used for);
left-join that list with the #ENROLLEES table to pick data for the existing dates and some defaults or NULLs for the non-existing ones.
It might be implemented like this:
… /* all your code up until the last WITH */
;
WITH cte AS (
SELECT CAST('7/1/11' AS date) AS dt
UNION ALL
SELECT DATEADD(d, 1, dt) as dt
FROM cte
WHERE dt < '12/1/11'
)
SELECT
cte.dt,
tmp.[Program code],
tmp.[program_name],
… /* other columns as necessary; you might also consider
enveloping some or all of the "tmp" columns in ISNULLs,
like in
ISNULL(tmp.[Program code], '(none)') AS [Program code]
to provide default values for absent data */
FROM cte
LEFT JOIN #ENROLLEES tmp ON cte.dt = tmp.pe_start_date
;
