I have the following query:
SELECT MS.idReg, MS.dsMotivo, A.contrato FROM MS
INNER JOIN S
ON S.motivoSiniestro = MS.idReg
INNER JOIN C
ON C.n__contrat = S.n__contrat
INNER JOIN A
ON A.n__article = C.n__article
Table MS has only 12 records, the ones I need and others have many more entries.
My problem is that I only want the 12 records from MS and their contrato column but I'm getting much more that that. Have tried many combinations of INNER, OUTER, LEFT and RIGHT joins. Any help?
You get too many records because there are several A.contrato values for each row in the MS table. Sql server does not know which one of all the A.contrato values to take so it returns all of them. First you need to decide which one you want.
If any will do you can simply write your query like this:
SELECT MS.idReg, MS.dsMotivo, MAX(A.contrato)
FROM MS
INNER JOIN S
ON S.motivoSiniestro = MS.idReg
INNER JOIN C
ON C.n__contrat = S.n__contrat
INNER JOIN A
ON A.n__article = C.n__article
GROUP BY MS.idReg, MS.dsMotivo
Try this one -
SELECT MS.idReg, MS.dsMotivo, A.contrato
FROM dbo.MS
OUTER APPLY (
SELECT TOP 1 A.contrato
FROM dbo.S
JOIN dbo.C ON C.n__contrat = S.n__contrat
JOIN dbo.A ON A.n__article = C.n__article
WHERE S.motivoSiniestro = MS.idReg
) s

In my query I want total file count and total closed files in the same table.
My first query:
select hi.eksper_id,ef.ad, count(hi.eksper_id) as total_files
from hasar_ihbar as hi
left outer join eksper_firma ef on ef.id=hi.eksper_id
group by hi.eksper_id,ef.ad
My second query:
select ef.id as eksper_id,ef.ad,count(ef.id) closed_files
from hasar_ihbar_rapor hir
left outer join hasar_ihbar hi on hi.id = hir.hasar_ihbar_id
left outer join eksper_firma ef on ef.id = hi.eksper_id
where hir.rapor_tipi = 3 group by ef.id,ef.ad
I want both combined and this is my code:
select ef.id as eksper_id,ef.ad,count(ef.id) closed_files, count(hi.id) AS total_files
from hasar_ihbar_rapor hir
left outer join hasar_ihbar hi on hi.id = hir.hasar_ihbar_id
left outer join eksper_firma ef on ef.id = hi.eksper_id
where hir.rapor_tipi = 3 group by ef.id,ef.ad
I don't know what I did wrong. Thanks for your help.
The double joins effect your counts since there are more rows.
A better way to combine both counts is to create a query that has two subqueries for each count.
SELECT id,
(SELECT COUNT(*)...) total_files,
(SELECT COUNT(*)...) closed_files
FROM ...
I am attempting to access data from the following tables:
OrgPlanYear
ProjOrgPlnYrJunction
DC
DCMaxEEContribLevel
DCNonDiscretionaryContribLevel
Basically, I need to inner join OrgPlanYear + DC and ProjOrgPlnYrJunction then I need to Left Join the remaining tables (tables 4 and 5) due to the fact the tables 1-3 have all the rows I need and only some have data in tables 4-5. I need several variables from each table. I also need the WHERE function to be across all fields (meaning I want all this data for a select group where projectID=919).
Please help!
I have tried many things with errors including attempting to use the Design Query side (i.e. JOIN function issues, badly formatted FROM function, etc.)! Here is an example of one excluding all variables I need:
SELECT
ProjOrgPlnYrJunction.fkeyProjectID, OrgPlanYear.OrgName, DC.PlanCode, DCNonDiscretionaryContribLevel.Age,DCNonDiscretionaryContribLevel.Service
FROM
(((OrgPlanYear INNER JOIN DC ON OrgPlanYear.OrgPlanYearID = DC.fkeyOrgPlanYearID) INNER JOIN ProjOrgPlnYrJunction ON OrgPlanYear.OrgPlanYearID = ProjOrgPlnYrJunction.fkeyOrgPlanYearID)
LEFT JOIN
(SELECT DCNonDiscretionaryContribLevel.Age AS Age, DCNonDiscretionaryContribLevel.Service AS Service FROM DCNonDiscretionaryContribLevel WHERE ProjOrgPlnYrJunction.fkeyProjectID)=919)
LEFT JOIN (
SELECT DCMaxEEContribLevel.EEContribRoth FROM EEContribRoth WHERE ProjOrgPlnYrJunction.fkeyProjectID)=919)
ORDER BY OrgPlanYear.OrgName;
Main issues with your query:
Missing ON clauses for each LEFT JOIN.
Referencing other table columns in SELECT and WHERE of a different subquery (e.g., FROM DCNonDiscretionaryContribLevel WHERE ProjOrgPlnYrJunction.fkeyProjectID).
Unmatched parentheses around subqueries and joins per Access SQL requirements.
See below adjusted SQL that now uses short table aliases. Be sure to adjust SELECT and ON clauses with appropriate columns.
SELECT p.fkeyProjectID, o.OrgName, DC.PlanCode, dcn.Age, dcn.Service, e.EEContribRoth
FROM (((OrgPlanYear o
INNER JOIN DC
ON o.OrgPlanYearID = DC.fkeyOrgPlanYearID)
INNER JOIN ProjOrgPlnYrJunction p
ON o.OrgPlanYearID = p.fkeyOrgPlanYearID)
LEFT JOIN
(SELECT Age AS Age, Service AS Service
FROM DCNonDiscretionaryContribLevel
WHERE fkeyProjectID = 919) AS dcn
ON dcn.fkeyProjectID = p.fkeyOrgPlanYearID)
LEFT JOIN
(SELECT EEContribRoth
FROM EEContribRoth
WHERE fkeyProjectID = 919) AS e
ON e.fkeyProjectID = p.fkeyProjectID
ORDER BY o.OrgName;
I have two columns i need to show all the records in column [PR] and some columns from column [EM]. The below SQL statement does not return all the records from column [PR].
SELECT
[PR].[WBS1], [EM].[FirstName], [EM].[LastName], [EM].[EMail]
FROM
[VisionDemo].[dbo].[PR]
JOIN
[VisionDemo].[dbo].[EM] ON [VisionDemo].[dbo].[PR].[Principal] = [VisionDemo].[dbo].[EM].[Employee]
How do I do this ?
Use a LEFT JOIN:
SELECT [PR].[WBS1],[EM].[FirstName],[EM].[LastName], [EM].[EMail]
FROM [VisionDemo].[dbo].[PR]
LEFT JOIN [VisionDemo].[dbo].[EM]
ON [VisionDemo].[dbo].[PR].[Principal] = [VisionDemo].[dbo].[EM].[Employee]
Use LEFT JOIN. This is fundamental stuff, go check out the FAQ
SELECT [PR].[WBS1],[EM].[FirstName],[EM].[LastName], [EM].[EMail]
FROM [VisionDemo].[dbo].[PR]
LEFT JOIN [VisionDemo].[dbo].[EM] --Use a left join
ON [VisionDemo].[dbo].[PR].[Principal] = [VisionDemo].[dbo].[EM].[Employee]
Can some one please explain the inner join syntax in the SQL below:
CREATE TABLE dataset AS
SELECT property.id
, amount.band
, amount."value"
FROM property
INNER JOIN (locality INNER JOIN amount ON locality.code = amount.code) ON (property.band = amount.band) AND (property.id = locality."UniqueId")
Why is the table locality defined before the second inner join? I've never come across such strange syntax.
Is there a more clearer way to right the same query so that someone can easily understand whats going on?
FROM property
INNER JOIN (locality INNER JOIN amount ON locality.code = amount.code)
ON (property.band = amount.band) AND (property.id = amount."UniqueId")
is the same as
FROM property
INNER JOIN amount ON property.band = amount.band AND property.id = amount."UniqueId"
INNER JOIN locality ON locality.code = amount.code
When INNER JOINs only, you can re-order them as you want.
(Any specific reason to JOIN locality? You don't select any of its columns. Is it some kind of EXISTS, or do you want multiple rows returned if there are several matching rows in that table?)
this is the original SQL, that works very well.
select a.sessionid
from session a
left
outer
join applicationinfo b
on a.sessionid=b.sessionid
left
outer
join license c
on a.sessionid=c.sessionid
limit 10
;
below is the converted SQL
SELECT s.sessionid
FROM
( SELECT *
FROM session a
LEFT
OUTER
JOIN applicationinfo b
ON (a.sessionid = b.sessionid)
)s
LEFT
OUTER
JOIN license c
ON (s.sessionid = c.sessionid)
limit 10
;
the second SQL will get 10 NULLs. Since those tables are left joined on the sessionid field. Suppose in the second SQL the s.sessionid should not be NULL.
Could someone tell me the reason why those two SQL cannot return the same result. Thanks.
