We have a scenario where we need to convert a particular query to power BI DAX query. Its kind of a self join with filter on multiple column.
SELECT IRF.file_number, IRF.date_updated, FileFrequency, ( SELECT TOP 1 new_value FROM #table1 A WHERE A.field_name = 'OperationsStatusCode' AND A.file_number = IRF.file_number AND A.date_updated <= IRF.date_updated ORDER BY A.date_updated DESC ) AS OpsStatus, ( SELECT TOP 1 new_value FROM #table1 A WHERE A.field_name = 'xyz' AND A.file_number = IRF.file_number AND A.date_updated <= IRF.date_updated ORDER BY A.date_updated DESC ) AS LabStatus INTO #Table2 FROM #table1;
We are trying to create a calculated column using DAX query but not able to get the desired result. Can ayone guide as o how ew can achieve this.
LabSecondCondition = CALCULATE( TOPN ( 1, VALUES(table1[new_value]) ), FiLTER( table1, table1[field_name] = "LaboratoryStatusCode" && table1[file_number] = table1[file_number] && table1[date_updated] <= table1[date_updated] ) )

I Have the following :
I used the select to got the Id from table as follow :
Select Id from t
data will be like this:
id
DG1
FS2
DD4
I want to pass result the result to the following sql statement using while or case
Depend of the result of the select statement
SELECT f.age_days, f.Body_wt,f.Act_Fcr_Day,f.Act_Growth ,
f.growth_gm as Growth ,f2.growth_gm as Growth1,
COALESCE(
(
SELECT TOP 1 Body_wt
FROM [dbo].[Broiler_Farms_Data] mi
WHERE mi.Age_Days > f.Age_Days and mi.flock_id = ??????
ORDER BY
Age_Days
), 0) - f.Body_wt AS diff
FROM [dbo].[Broiler_Farms_Data] f
How can I do it .
thanks
I find this type of logic easier to follow with outer apply:
SELECT f.age_days, f.Body_wt, f.Act_Fcr_Day, f.Act_Growth,
f.growth_gm as Growth, f2.growth_gm as Growth1,
(COALESCE(mi.Body_wt, 0) - f.Body_wt0 AS diff
FROM [dbo].[Broiler_Farms_Data] f OUTER APPLY
(SELECT TOP 1 mi.*
FROM [dbo].[Broiler_Farms_Data] mi
WHERE mi.Age_Days > f.Age_Days and mi.flock_id = ??????
ORDER BY mi.Age_Days
) mi;
Then, if I understand correctly:
SELECT t.id, f.age_days, f.Body_wt, f.Act_Fcr_Day, f.Act_Growth,
f.growth_gm as Growth, f2.growth_gm as Growth1,
(COALESCE(mi.Body_wt, 0) - f.Body_wt0 AS diff
FROM [dbo].[Broiler_Farms_Data] f CROSS JOIN
(Select Id from t
) t OUTER APPLY
(SELECT TOP 1 mi.*
FROM [dbo].[Broiler_Farms_Data] mi
WHERE mi.Age_Days > f.Age_Days and mi.flock_id = t.id
ORDER BY mi.Age_Days
) mi;
This also includes the id in the SELECT, because that seems desirable.
Aggregate functions in VARCHAR columns are not advised. If you have a Primary Key or a surrogate key which can be used, then it will be helpful. Use the below query to use WHILE LOOP.
DECLARE #Id VARCHAR(10) = ''
WHILE 1=1
BEGIN
SELECT #Id = MIN(Id) from t WHERE Id > #Id
IF #Id IS NULL
BREAK
SELECT f.age_days, f.Body_wt,f.Act_Fcr_Day,f.Act_Growth ,
f.growth_gm as Growth ,f2.growth_gm as Growth1,
COALESCE(
(
SELECT TOP 1 Body_wt
FROM [dbo].[Broiler_Farms_Data] mi
WHERE mi.Age_Days > f.Age_Days and mi.flock_id = #Id
ORDER BY
Age_Days
), 0) - f.Body_wt AS diff
FROM [dbo].[Broiler_Farms_Data] f
END
The code below joins two tables and I need to extract only the latest date per account, though it holds multiple accounts and history records. I wanted to use the MAX function, but not sure how to incorporate it for this case. I am using My SQL server.
Appreciate any help !
select
PROP.FileName,PROP.InsName, PROP.Status,
PROP.FileTime, PROP.SubmissionNo, PROP.PolNo,
PROP.EffDate,PROP.ExpDate, PROP.Region,
PROP.Underwriter, PROP_DATA.Data , PROP_DATA.Label
from
Property.dbo.PROP
inner join
Property.dbo.PROP_DATA on Property.dbo.PROP.FileID = Actuarial.dbo.PROP_DATA.FileID
where
(PROP_DATA.Label in ('Occupancy' , 'OccupancyTIV'))
and (PROP.EffDate >= '42278' and PROP.EffDate <= '42643')
and (PROP.Status = 'Bound')
and (Prop.FileTime = Max(Prop.FileTime))
order by
PROP.EffDate DESC
Assuming your DBMS supports windowing functions and the with clause, a max windowing function would work:
with all_data as (
select
PROP.FileName,PROP.InsName, PROP.Status,
PROP.FileTime, PROP.SubmissionNo, PROP.PolNo,
PROP.EffDate,PROP.ExpDate, PROP.Region,
PROP.Underwriter, PROP_DATA.Data , PROP_DATA.Label,
max (PROP.EffDate) over (partition by PROP.PolNo) as max_date
from Actuarial.dbo.PROP
inner join Actuarial.dbo.PROP_DATA
on Actuarial.dbo.PROP.FileID = Actuarial.dbo.PROP_DATA.FileID
where (PROP_DATA.Label in ('Occupancy' , 'OccupancyTIV'))
and (PROP.EffDate >= '42278' and PROP.EffDate <= '42643')
and (PROP.Status = 'Bound')
and (Prop.FileTime = Max(Prop.FileTime))
)
select
FileName, InsName, Status, FileTime, SubmissionNo,
PolNo, EffDate, ExpDate, Region, UnderWriter, Data, Label
from all_data
where EffDate = max_date
ORDER BY EffDate DESC
This also presupposes than any given account would not have two records on the same EffDate. If that's the case, and there is no other objective means to determine the latest account, you could also use row_numer to pick a somewhat arbitrary record in the case of a tie.
Using straight SQL, you can use a self-join in a subquery in your where clause to eliminate values smaller than the max, or smaller than the top n largest, and so on. Just set the number in <= 1 to the number of top values you want per group.
Something like the following might do the trick, for example:
select
p.FileName
, p.InsName
, p.Status
, p.FileTime
, p.SubmissionNo
, p.PolNo
, p.EffDate
, p.ExpDate
, p.Region
, p.Underwriter
, pd.Data
, pd.Label
from Actuarial.dbo.PROP p
inner join Actuarial.dbo.PROP_DATA pd
on p.FileID = pd.FileID
where (
select count(*)
from Actuarial.dbo.PROP p2
where p2.FileID = p.FileID
and p2.EffDate <= p.EffDate
) <= 1
and (
pd.Label in ('Occupancy' , 'OccupancyTIV')
and p.Status = 'Bound'
)
ORDER BY p.EffDate DESC
Have a look at this stackoverflow question for a full working example.
Not tested
with temp1 as
(
select foo
from bar
whre xy = MAX(xy)
)
select PROP.FileName,PROP.InsName, PROP.Status,
PROP.FileTime, PROP.SubmissionNo, PROP.PolNo,
PROP.EffDate,PROP.ExpDate, PROP.Region,
PROP.Underwriter, PROP_DATA.Data , PROP_DATA.Label
from Actuarial.dbo.PROP
inner join temp1 t
on Actuarial.dbo.PROP.FileID = t.dbo.PROP_DATA.FileID
ORDER BY PROP.EffDate DESC
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.
Im trying to write what I believe is a rather complicated SQL query but Im working with limited SQL knowledge. I have this query:
SELECT
analysisvalue.analysisid,
heatname,
analysistime,
sampletype,
grade,
productid,
element,
value
FROM
dbo.AnalysisValue
INNER JOIN
dbo.CAnalysis
ON
dbo.AnalysisValue.AnalysisID = dbo.CAnalysis.AnalysisID
WHERE
heatname = 'A7M0066'
ORDER BY
analysisvalue.analysisid ASC,
element
and this query:
SELECT
*
FROM
S_analysis
WHERE
heat_no = 'A7M0066'
I need to modify the second query to also include * from S_analysis WHERE heat_no = 'A7M0066' but also all records including those without that heat_no where analysis_datetime is between the analysis time of the last record from the first query and two hours that follow that time.
The S_analysis table structure for the second query is:
analysis_datetime(datetime, not null)
heat_no(varchar(7), not null)
comment(varchar(40), null)
Then about 30 other columns of type (real, null)
The table structure of AnalysisValue in the first query is:
AnalysisID(int, not null)
Element(char(9), not null)
Value(real, null)
The table structure of CAnalysis in the first query is:
AnalysisID(PK, int, not null)
HeatName(char(7), null)
AnalysisTime(datetime, null)
SampleType(char(5), null)
Grade(char(4), null)
ProductID(char(14), null)
Try this (never used sql-server, but it should produce your expected results)
SELECT
*
FROM
S_analysis
CROSS JOIN
(
SELECT TOP 1
analysistime
FROM
dbo.CAnalysis
WHERE
heatname = 'A7M0066'
ORDER BY
analysistime DESC ) c
WHERE
heat_no = 'A7M0066'
OR ( heat_no IS NULL AND s.analysis_datetime BETWEEN c.analysistime AND DATEADD(hh, 2, c.analysistime ) )
Since you need only top row from your 1st query .You can use Cross join with the 2nd query to get the desired result
;with cte as
(SELECT
analysisvalue.analysisid,
heatname,
analysistime,
sampletype,
grade,
productid,
element,
value
FROM
dbo.AnalysisValue
INNER JOIN
dbo.CAnalysis
ON
dbo.AnalysisValue.AnalysisID = dbo.CAnalysis.AnalysisID
WHERE
heatname = 'A7M0066'
)
SELECT
*
FROM
S_analysis s
CROSS JOIN (SELECT TOP 1 analysistime
FROM cte
ORDER BY analysisid desc
) c
WHERE s.heat_no = 'A7M0066' OR
(s.analysis_datetime BETWEEN c.analysistime AND DATEADD(hh, 2, c.analysistime ))
I have a complicated select statement that when it is executed, I give it a date or date range I want and the output comes out. The problem is I don't know how to join the same SQL statement with the first Statement having 1 date range and the second statement having another data range. Example below:
When I execute the select statement, I choose for the Month of November:
EMPLID NAME Current_Gross_Hours(November)
When I execute the select statement again, I choose from January to November:
EMPLID NAME Year_To_Date_Hours(January - November)
What I want:
EMPLID NAME Current_Gross_Hours(November) Year_To_Date_Hours(January - November)
The SQL Select statement runs correctly if execute by themselves. But I don't know how to join them.
Here is the SQL code that I want to write, but I don't know how to write the SQL statement correctly. Any help or direction is greatly appreciated.

You are missing a SELECT ... FROM at the start. The AS keyword only works when creating column aliases, not query block aliases. Quotation marks are only necessary for case-sensitive column names - they don't look incorrect in your example but they frequently cause mistakes.
