Hello I have been trying to delete a repeated value on the following UNION query with the following results (image). How can I filter out the value LW_ID=8232 with AANTALLN =0. I need to find a way taht if in the first query AANTALLN >0 is found, then on the second part of the union query not insert it again. Thanks "
With LESEENHEIDLOOPBAAN as (

)
SELECT
*
FROM
LESEENHEIDLOOPBAAN
UNION
SELECT
*
FROM
LESEENHEIDLOOPBAANNULL ROWS 1000
Try this out using ROW_NUMBER:
SELECT * FROM (
SELECT
ROW_NUMBER () OVER (PARTITION BY LW_ID ORDER BY AANTALLN DESC) AS RN
,* FROM
(
SELECT * FROM
LESEENHEIDLOOPBAAN
UNION
SELECT
*
FROM
LESEENHEIDLOOPBAANNULL ROWS 1000
)
)
) WHERE RN = 1
This way you eliminate the duplicates.

How do I combine multiple CTE into one query?
My query is attempting to determine if there are duplicate records and if so only keep the max(AzureBlobInsertDate) record and remove other duplicates. then combine all the results from the CurAccounts & Devices tables.
Any assistance you can offer is greatly appreciated.
I am working with a tool that would extract some data from an Access Database. So basically, i am working on a query to get this data.
Below is the code i am currently working on.
I am getting an error: Syntax error in FROM clause
I can't seem to find where the query is going wrong. I would appreciate any help! Thank youu.

I am having no luck attempting to get the top (x number) of rows from a joined table. I want the top 2 resources (ordered by name) which in this case should be Katie and Simon and regardless of what I've tried, I can't seem to get it right. You can see below what I've commented out - and what looks like it should work (but doesn't). I cannot use a union. Any ideas?
select distinct
RTRESOURCE.RNAME as Resource,
RTTASK.TASK as taskname, SUM(distinct SOTRAN.QTY2BILL) AS quantitytobill from SOTRAN AS SOTRAN INNER JOIN RTTASK AS RTTASK ON sotran.taskid = rttask.taskid

//and RTRESOURCE.RNAME in ( select distinct top 2 RTRESOURCE.RNAME from RTRESOURCE order by RTRESOURCE.RNAME)
//and ( select count(*) from RTRESOURCE RTRESOURCE2 where RTRESOURCE2.RNAME = RTRESOURCE.RNAME ) <= 2
GROUP BY RTRESOURCE.rname,RTTASK.task,RTTASK.taskid,RTTASK.mdsstring ORDER BY Resource,taskname
You should provide a schema.
But lets assume your query work. You create a CTE.
WITH youQuery as (
SELECT *
FROM < you big join query>
), maxBill as (
SELECT Resource, Max(quantitytobill) as Bill
FROM yourQuery
)
SELECT top 2 *
FROM maxBill
ORDER BY Bill
IF you want top 2 alphabetical
WITH youQuery as (
SELECT *
FROM < you big join query>
), Names as (
SELECT distinct Resource
FROM yourQuery
Order by Resource
)
SELECT top 2 *
FROM Names
I am having issue when trying to make a the sub query shown in the first filter dynamically based on one of the results returned from the query. Can someone please tell me what I am doing wrong. In the first subquery it worked.

Error I am getting is:

I would say that a good option here would be to use a CTE, or Common Table Expression. You can do something similar to the following:
WITH CTE_X AS(
SELECT VAL_A
,VAL_B
FROM TABLE_A)
,CTE_Y AS(
SELECT VAL_C
,VAL_B
FROM TABLE_B)
SELECT VAL_A
,VAL_B
FROM CTE_X X
JOIN CTE_Y Y
ON X.VAL_A = Y.VAL_C;
While this isn't specific to your example, it does show that CTE's create a sort of temporary "in memory" table that you can access in a subsequent query. This should allow you to issue your inner two subselects as a CTE, and then use the CTE in the "SELECT MAX( MAX_DATE - MIN_DATE ) AS NUM_CONS_DAYS" query.
You cannot reference columns from the outer select in the subselect, no more than 1 level deep anyway. If I correctly understand what you're doing, you'll probably need to join DWH.MQT_SUMMARY_WATER_READINGS and DWH.DWH_WMETER_CONTEXT in the outer select.
WITH y AS (
WITH x AS (
SELECT * FROM MyTable
)
SELECT * FROM x
)
SELECT * FROM y
Does something like this work? I tried it earlier but I couldn't get it to work.
While not strictly nested, you can use common table expressions to reuse previous queries in subsequent ones.
To do this, the form of the statement you are looking for would be
WITH x AS
(
SELECT * FROM MyTable
),
y AS
(
SELECT * FROM x
)
SELECT * FROM y
You can do the following, which is referred to as a recursive query:
WITH y
AS
(
SELECT x, y, z
FROM MyTable
WHERE [base_condition]
UNION ALL
SELECT x, y, z
FROM MyTable M
INNER JOIN y ON M.[some_other_condition] = y.[some_other_condition]
)
SELECT *
FROM y
You may not need this functionality. I've done the following just to organize my queries better:
WITH y
AS
(
SELECT *
FROM MyTable
WHERE [base_condition]
),
x
AS
(
SELECT *
FROM y
WHERE [something_else]
)
SELECT *
FROM x
With does not work embedded, but it does work consecutive
;WITH A AS(
...
),
B AS(
...
)
SELECT *
FROM A
UNION ALL
SELECT *
FROM B
EDIT
Fixed the syntax...
Also, have a look at the following example

These answers are pretty good, but as far as getting the items to order properly, you'd be better off looking at this article

Here's an example of his query.
WITH paths AS (
SELECT
EmployeeID,
CONVERT(VARCHAR(900), CONCAT('.', EmployeeID, '.')) AS FullPath
FROM EmployeeHierarchyWide
WHERE ManagerID IS NULL
UNION ALL
SELECT
ehw.EmployeeID,
CONVERT(VARCHAR(900), CONCAT(p.FullPath, ehw.EmployeeID, '.')) AS FullPath
FROM paths AS p
JOIN EmployeeHierarchyWide AS ehw ON ehw.ManagerID = p.EmployeeID
)
SELECT * FROM paths order by FullPath
we can create nested cte.please see the below cte in example
;with cte_data as
(
Select * from [HumanResources].[Department]
),cte_data1 as
(
Select * from [HumanResources].[Department]
)
select * from cte_data,cte_data1
I was trying to measure the time between events with the exception of what one entry that has multiple processes between the start and end. I needed this in the context of other single line processes.
I used a select with an inner join as my select statement within the Nth cte. The second cte I needed to extract the start date on X and end date on Y and used 1 as an id value to left join to put them on a single line.
Works for me, hope this helps.
cte_extract
as
(
select ps.Process as ProcessEvent
, ps.ProcessStartDate
, ps.ProcessEndDate
-- select strt.*
from dbo.tbl_some_table ps
inner join (select max(ProcessStatusId) ProcessStatusId
from dbo.tbl_some_table
where Process = 'some_extract_tbl'
and convert(varchar(10), ProcessStartDate, 112) < '29991231'
) strt on strt.ProcessStatusId = ps.ProcessStatusID
),
cte_rls
as
(
select 'Sample' as ProcessEvent,
x.ProcessStartDate, y.ProcessEndDate from (
select 1 as Id, ps.Process as ProcessEvent
, ps.ProcessStartDate
, ps.ProcessEndDate
-- select strt.*
from dbo.tbl_some_table ps
inner join (select max(ProcessStatusId) ProcessStatusId
from dbo.tbl_some_table
where Process = 'XX Prcss'
and convert(varchar(10), ProcessStartDate, 112) < '29991231'
) strt on strt.ProcessStatusId = ps.ProcessStatusID
) x
left join (
select 1 as Id, ps.Process as ProcessEvent
, ps.ProcessStartDate
, ps.ProcessEndDate
-- select strt.*
from dbo.tbl_some_table ps
inner join (select max(ProcessStatusId) ProcessStatusId
from dbo.tbl_some_table
where Process = 'YY Prcss Cmpltd'
and convert(varchar(10), ProcessEndDate, 112) < '29991231'
) enddt on enddt.ProcessStatusId = ps.ProcessStatusID
) y on y.Id = x.Id
),
.... other ctes
Nested 'With' is not supported, but you can always use the second With as a subquery, for example:
WITH A AS (
--WITH B AS ( SELECT COUNT(1) AS _CT FROM C ) SELECT CASE _CT WHEN 1 THEN 1 ELSE 0 END FROM B --doesn't work
SELECT CASE WHEN count = 1 THEN 1 ELSE 0 END AS CT FROM (SELECT COUNT(1) AS count FROM dual)
union all
select 100 AS CT from dual
)
select CT FROM A
