I am using ROWNUM for fetching 999 rows in the following manner:
SELECT COUNT(*)
FROM PS_MMC_JOBDSSOA_MV JOB, PS_MMC_PERDSSOA_MV PER
WHERE PER.EMPLID = JOB.EMPLID AND
PER.ASOFDATE = (SELECT MAX(PER1.ASOFDATE) FROM PS_MMC_PERDSSOA_MV PER1
WHERE PER1.EMPLID = PER.EMPLID AND PER1.ASOFDATE <= SYSDATE) AND
JOB.ASOFDATE = (SELECT MAX(JOB1.ASOFDATE) FROM PS_MMC_JOBDSSOA_MV JOB1
WHERE JOB1.EMPLID = JOB.EMPLID AND JOB1.ASOFDATE <=SYSDATE) AND ROWNUM<1000;
I have re wrote the above sql query using left outer join:
SELECT COUNT(*)
FROM PS_MMC_JOBDSSOA_MV JOB LEFT OUTER JOIN PS_MMC_PERDSSOA_MV PER
ON (PER.EMPLID = JOB.EMPLID)
AND PER.ASOFDATE = ((SELECT MAX(PER1.ASOFDATE) FROM PS_MMC_PERDSSOA_MV PER1 WHERE
PER1.EMPLID = PER.EMPLID AND PER1.ASOFDATE <= SYSDATE)
AND JOB.ASOFDATE = (SELECT MAX(JOB1.ASOFDATE) FROM PS_MMC_JOBDSSOA_MV JOB1 WHERE
JOB1.EMPLID = JOB.EMPLID AND JOB1.ASOFDATE <= SYSDATE)) WHERE ROWNUM <1000;
ROWNUM is not working with Outer join. I am getting more than 1000 rows.
Could anybody suggest what I am doing wrong.
I have found this below sql query which is working with ROWNUM
SELECT * from (SELECT JOB.DEPTID, JOB.EMPL_STATUS, JOB.LOCATION, JOB.MMC_LOCATION_DESCR, JOB.CITY, JOB."STATE", PER."NAME" FROM
PS_MMC_JOBDSSOA_MV JOB LEFT OUTER JOIN PS_MMC_PERDSSOA_MV PER ON (PER.EMPLID = JOB.EMPLID)
AND PER.ASOFDATE = (SELECT MAX(PER1.ASOFDATE) FROM PS_MMC_PERDSSOA_MV PER1
WHERE PER1.EMPLID = PER.EMPLID AND PER1.ASOFDATE <= SYSDATE) AND JOB.ASOFDATE =
(SELECT MAX(JOB1.ASOFDATE) FROM PS_MMC_JOBDSSOA_MV JOB1 WHERE JOB1.EMPLID = JOB.EMPLID AND JOB1.ASOFDATE <= SYSDATE))
where ROWNUM <1000

this is my code :
SELECT DISTINCT Emps.name, Degrees.Name AS degree, Degrees.Date AS degree_date
FROM Emps INNER JOIN
Degrees ON Emps.id = Degrees.empId
but distict dosn't work , i want this result
i want distict name with degree which has max id or max date
thanks for all i found the solution
SELECT e.name, d.Name AS degree
FROM Emps AS e
full JOIN (
SELECT t.*, ROW_NUMBER() OVER (PARTITION BY t.empId ORDER BY t.id DESC) AS rn FROM Degrees AS t
) AS d ON e.id = d.empId
WHERE d.rn = 1
I'm still kinda new to SQL; please spare me. I have an issue with trying to join a table or another view to my existing query below.
The last question I had asked refers to joining the two subqueries and giving them an alias in order for the join to work (something I still don't understand?) I'm trying to join a table and another subquery to the query below. But I'm not quite sure how I could continue adding subqueries to it.
I don't really understand how the alias names allowed the subqueries to be joined, and if I add another subquery, then I'll add another alias?
Any assistance you could provide would be much appreciated. Apologize in advanced for the formatting :/

I have a recent request to include Work ItemTag information in a daily SSRS report that I generate. I was led to the SQL query below. The problem is that I cannot find a table or a view with the "WorkItemsAre" in the name. So giving that I have the WorkItemSK, System_Id, ProjectSK and CollectionGUID among many other things, how and where can I get the tags querying directly against the TFS database (I know querying against the TFS databases is not recommended but It's in my requirements)?
SELECT DISTINCT WorkItemsAre.ID, WorkItemsAre.Title, tbl_TagDefinition.Name
--,tbl_PropertyValue.ArtifactId, *
FROM tbl_TagDefinition
LEFT JOIN tbl_PropertyDefinition ON tbl_PropertyDefinition.Name =
'Microsoft.TeamFoundation.Tagging.TagDefinition.' + CONVERT(NVARCHAR(400),
tbl_TagDefinition.TagId)
LEFT JOIN tbl_PropertyValue ON tbl_PropertyValue.PropertyId =
tbl_PropertyDefinition.PropertyId
--LEFT JOIN WorkItemLongTexts ON WorkItemLongTexts.ID =
tbl_PropertyValue.ArtifactId
left join WorkItemsAre on WorkItemsAre.ID = tbl_PropertyValue.ArtifactId
WHERE
(
SELECT SUM(CASE WHEN IntValue = 0 THEN 1 ELSE -1 END) NB
FROM tbl_PropertyValue PROP_CNT
WHERE PROP_CNT.PropertyId = tbl_PropertyDefinition.PropertyId
AND WorkItemsAre.ID = PROP_CNT.ArtifactId
) > 0
TFS warehouse does not contain tags. For TFS 2018 (maybe also for tfs 2017) you can find information in table tbl_WorkItemCoreLatest in operational database (in my case: Tfs_DefaultCollection)
SELECT DISTINCT tbl_WorkItemCoreLatest.Id,tbl_TagDefinition.Name
--,tbl_PropertyValue.ArtifactId, *
FROM tbl_TagDefinition
LEFT JOIN tbl_PropertyDefinition ON tbl_PropertyDefinition.Name = 'Microsoft.TeamFoundation.Tagging.TagDefinition.' + CONVERT(NVARCHAR(400), tbl_TagDefinition.TagId)
LEFT JOIN tbl_PropertyValue ON tbl_PropertyValue.PropertyId = tbl_PropertyDefinition.PropertyId
--LEFT JOIN WorkItemLongTexts ON WorkItemLongTexts.ID = tbl_PropertyValue.ArtifactId
left join tbl_WorkItemCoreLatest on tbl_WorkItemCoreLatest.Id = tbl_PropertyValue.ArtifactId
WHERE
(
SELECT SUM(CASE WHEN IntValue = 0 THEN 1 ELSE -1 END) NB
FROM tbl_PropertyValue PROP_CNT
WHERE PROP_CNT.PropertyId = tbl_PropertyDefinition.PropertyId
AND tbl_WorkItemCoreLatest.Id = PROP_CNT.ArtifactId
) > 0
I've got the following scope on the Project model to find projects to which at least 80 crowdfunding pledges have been done or projects which have reached their goal already:
class Project < ActiveRecord::Base
scope :popular, -> { collecting.where("80 <= (?) OR goal <= (?)",
Pledge.select('COUNT(*)').where("project_id = projects.id").where(paid: true),
Pledge.select('SUM(amount)').where("project_id = projects.id").where(paid: true))
}
(...)
end
This works just fine and produces the following SQL for Postres:
Project.popular
# SELECT "projects".* FROM "projects" WHERE "projects"."state" = 'collecting' AND (80 <= (SELECT COUNT(*) FROM "pledges" WHERE (project_id = projects.id) AND "pledges"."paid" = 't') OR goal <= (SELECT SUM(amount) FROM "pledges" WHERE (project_id = projects.id) AND "pledges"."paid" = 't'))
It's important to get the count as well:
Project.popular.count
# SELECT COUNT(*) FROM "projects" WHERE "projects"."state" = 'collecting' AND (80 <= (SELECT COUNT(*) FROM "pledges" WHERE (project_id = projects.id) AND "pledges"."paid" = 't') OR goal <= (SELECT SUM(amount) FROM "pledges" WHERE (project_id = projects.id) AND "pledges"."paid" = 't'))
Okay, the subselects are nice, but I have this feeling that there's a better and more efficient way to do this. I've tried joins and sum, but the mandatory group to use aggregate functions breaks Project.popular.count.
Any ideas how to refactor this? Maybe just a way to do where("project_id = projects.id") in Hash notation?
I don't know if this is any good for you because I can't express the below query in the ActiveRecord lingo but if you can it will be a big improvement over the poor query currently being generated
select "projects".*, project_count, project_amount
from
"projects"
inner join (
select
id,
count(*) as project_count,
sum(amount) as project_amount
from pledges
group by id
where paid
) pledges using (id)
where
"projects"."state" = 'collecting'
and
(project_count >= 80 or project_amount >= goal)
Thanks, #Clodonaldo! With a few litte touches, your query works like a charm:
select "projects".*, pledges_count, pledges_sum
from
"projects"
inner join (
select
project_id as id,
count(*) as pledges_count,
sum(amount) as pledges_sum
from pledges
where paid
group by project_id
) pledges using (id)
where
"projects"."state" = 'collecting'
and
(pledges_count >= 80 or pledges_sum >= goal)
Not sure thou whether AR or AREL can build this.
UPDATE:
The shortest I can come up with is (I don't need the count and sum values):
Project.collecting.joins(
"INNER JOIN (",
Pledge.paid.group(:project_id).select("
project_id AS id,
COUNT(*) AS count,
SUM(amount) AS sum
").to_sql,
") pledges USING (id)"
).where("count >= 80 OR sum >= goal")
The above produces:
SELECT "projects".*
FROM
"projects"
INNER JOIN (
SELECT
project_id AS id,
COUNT(*) AS count,
SUM(amount) AS sum
FROM "pledges"
WHERE "pledges"."paid" = 't'
GROUP BY project_id
) pledges USING (id)
WHERE
"projects"."state" = 'collecting'
AND
(count >= 80 OR sum >= goal)
I'm struggling to figure out the issue with my SQL table using compute sum.
All that is displayed where the sum of the column should be is a blank box!

may be this help you, as I understood you need SUM(Rental_Line.Qty) OVER (PARTITION BY Rental.Rental_ID)
