I'm trying to make my first recursive query in SQL and get an unxpected syntax error with inner join clause. I don't understand what causes this error. The query is simple it is just to select all employee attached to their boss with simple rule: BOSS_POS_ID = POS_ID
Here is example of my data:
POS_ID;POS_NAME;BOSS_POS_ID
32520602;CEO;
32809988;Manager;32520602
35244656;Vice;32520602
35244652;CEO assistant;32520602
35042934;Manager;32520602
35255704;Manager;32520602
35342468;Director;32520602
34091164;Director;32520602
35236439;Excecutive;32520602
32809978;Director;32520602
Here is my query:
with recursive subordinates as
(
select POS_ID, POS_NAME, BOSS_POS_ID
from gdm.hr_oss
where
POS_ID = 32520602
and CAL_DAY = (select max(CAL_DAY) from gdm.hr_oss)
union select
e.POS_ID,
e.POS_NAME,
e.BOSS_POS_ID
from gdm.hr_oss e
where CAL_DAY = (select max(CAL_DAY) from gdm.hr_oss)
inner join subordinates s on s.POS_ID = e.BOSS_POS_ID
)
select * from subordinates;
Here is error:

I have a query that I've written in Prisma. It basically connects 7 tables, each of which only has maybe 2-4 rows. Yes, 2-4 rows, that's it.
The query that Prisma generates can take upwards of 2-3 minutes to run.
When I write the query directly in SQL, it runs in 1ms.
So, the query I write looks like :
SELECT *
FROM rubricCellAssessment
INNER JOIN rubricAssessment ON rubricCellAssessment.rubricAssessmentId = rubricAssessment.id
INNER JOIN rubricCell ON rubricCellAssessment.rubricCellId = rubricCell.id
INNER JOIN criteriaDescriptor ON rubricCell.criteriaDescriptorId = criteriaDescriptor.id
INNER JOIN criteria ON criteriaDescriptor.criteriaId = criteria.id
INNER JOIN skill ON criteria.skillId = skill.id
INNER JOIN user AS student ON rubricAssessment.studentId = student.id
INNER JOIN user AS assessor ON rubricAssessment.assessorId = assessor.id
LEFT JOIN studentContentBase ON rubricAssessment.studentContentBaseId = studentContentBase.id
WHERE student.userTypeId = 1
AND assessor.userTypeId IN (2, 1000, 3)
AND skill.id = 'bd47bfff-760c-4fec-86d2-1063bbd89d63'
AND criteriaDescriptor.criteriaId = criteria.id
AND rubricCell.criteriaDescriptorId = criteriaDescriptor.id;
The query prisma produces looks like this:
select
`lp-mvp`.`RubricCellAssessment`.`id`,
`lp-mvp`.`RubricCellAssessment`.`createdAt`,
`lp-mvp`.`RubricCellAssessment`.`updatedAt`,
`lp-mvp`.`RubricCellAssessment`.`assessmentValue`,

Is there any way to optimize this (other than use RAWsql?)? I'm surprised Prisma's code generation is this bad, but I'd rather not move away from it at this point if possible.
All help gratefully accepted.

AFAIK, this is correct and should run. It Fails with syntax error on Delete. What am I missing?
Thanks for any help.

If I add new event_event or new product_product I'll get a new definition of row_number in my view, then the column ID of my view is not stable.
at least you can't use row_number as Id of the view,
If you insist to use row_number, you can use the Order By "creation DATE" by this way all new records will be as last lines in the view and this will not change the correspondency between ID (row_number) and other columns.
Hope that helps !
Very likely the execution plan of your query depends on the columns you select. Compare the execution plans!
Your id is generated using the row_number window function. Now window functions are executed before the ORDER BY clause, so the order will depend on the execution plan and hence on the columns you select.
Using row_number without an explicit ordering doesn't make any sense.
To fix that, don't use
row_number() OVER ()
but
row_number() OVER (ORDER BY e.id, pt.categ_id, p.id)
so that you have a reliable ordering.
In addition, you should omit the ORDER BY clause at the end.
I'm trying to get lateral to work in a Postgres 9.5.3 query.
select b_ci."IdOwner",
ci."MinimumPlaces",
ci."MaximumPlaces",
(select count(*) from "LNK_Stu_CI" lnk
where lnk."FK_CourseInstanceId" = b_ci."Id") as "EnrolledStudents",
from "Course" c
join "DBObjectBases" b_c on c."Id" = b_c."Id"
join "DBObjectBases" b_ci on b_ci."IdOwner" = b_c."Id"
join "CourseInstance" ci on ci."Id" = b_ci."Id",
lateral (select ci."MaximumPlaces" - "EnrolledStudents") x
I want the right-most column to be the result of "MaximumPlaces" - "EnrolledStudents" for that row but am struggling to get it to work. At the moment PG is complaining that "EnrolledStudents" does not exist - which is exactly the point of "lateral", isn't it?
select b_ci."IdOwner",
ci."MinimumPlaces",
ci."MaximumPlaces",
(select count(*) from "LNK_Stu_CI" lnk
where lnk."FK_CourseInstanceId" = b_ci."Id") as "EnrolledStudents",
lateral (select "MaximumPlaces" - "EnrolledStudents") as "x"
from "Course" c
join "DBObjectBases" b_c on c."Id" = b_c."Id"
join "DBObjectBases" b_ci on b_ci."IdOwner" = b_c."Id"
join "CourseInstance" ci on ci."Id" = b_ci."Id"
If I try inlining the lateral clause (shown above) in the select it gets upset too and gives me a syntax error - so where does it go?
Thanks,
Adam.
You are missing the point with LATERAL. It can access columns in tables in the FROM clause, but not aliases defined in SELECT clause.
If you want to access alias defined in SELECT clause, you need to add another query level, either using a subquery in FROM clause (AKA derived table) or using a CTE (Common Table Expression). As CTE in PostgreSQL acts as an optimization fence, I strongly recommend going with subquery in this case, like:
select
-- get all columns on the inner query
t.*,
-- get your new expression based on the ones defined in the inner query
t."MaximumPlaces" - t."EnrolledStudents" AS new_alias
from (
select b_ci."IdOwner",
ci."MinimumPlaces",
ci."MaximumPlaces",
(select count(*) from "LNK_Stu_CI" lnk
where lnk."FK_CourseInstanceId" = b_ci."Id") as "EnrolledStudents",
from "Course" c
join "DBObjectBases" b_c on c."Id" = b_c."Id"
join "DBObjectBases" b_ci on b_ci."IdOwner" = b_c."Id"
join "CourseInstance" ci on ci."Id" = b_ci."Id"
) t
