Convert SQL To DAX

bpdax — Thu, 01 Feb 2024 13:17:16 GMT

Hi,

I am very new to DAX and have to convert some SSRS into paginated reports using powerbi data source as the model has already been published. I am stuggling converting this stored procedure into DAX, any help would be very much appreciated. The parameters in this stored procedure are multi-valued ones:

SELECT DISTINCT

table.StaffID,

Team,

FirstName,

LastName,

CourseName,

DueOnDate

FROM [database].[dbo].[table]

INNER JOIN

(

SELECT

StaffID,

SUM(TrainingTracked) TrainingTracked,

SUM(Denominator) - SUM(Numerator) DemNumDiff,

SUM(TrackedDenominator) - SUM(TrackedNumerator) TrackDemNumDiff,

CASE WHEN SUM(TrainingTracked) = 16 and SUM(TrackedDenominator) - SUM(TrackedNumerator) > 0 THEN 1

WHEN SUM(TrainingTracked) <> 16 and SUM(Denominator) - SUM(Numerator) > 0 THEN 1

ELSE 0

END NotComplaint

FROM [database].[dbo].[table]

WHERE [Compliant] = 0

AND Team IN (@Team)

AND Course IN (@Course)

GROUP BY StaffID

) A

ON table.StaffID = a.StaffID

WHERE A.NotComplaint = 1

Thank you

Hi bpdax ,

Please try using below method

EVALUATE
VAR NotCompliantTable =
SUMMARIZE (
FILTER (
VALUES ( 'database'[Team] ),
[Compliant] = 0
&& [NotComplaint] = 1
),
'database'[StaffID],
"TrainingTracked", SUM ( 'database'[TrainingTracked] ),
"DemNumDiff", SUM ( 'database'[Denominator] ) - SUM ( 'database'[Numerator] ),
"TrackDemNumDiff", SUM ( 'database'[TrackedDenominator] ) - SUM ( 'database'[TrackedNumerator] ),
"NotComplaint",
SWITCH (
TRUE (),
SUM ( 'database'[TrainingTracked] ) = 16
&& SUM ( 'database'[TrackedDenominator] ) - SUM ( 'database'[TrackedNumerator] ) > 0, 1,
SUM ( 'database'[TrainingTracked] ) <> 16
&& SUM ( 'database'[Denominator] ) - SUM ( 'database'[Numerator] ) > 0, 1,
0
)
)
EVALUATE
SUMMARIZE (
'database',
'database'[StaffID],
'database'[Team],
'database'[FirstName],
'database'[LastName],
'database'[CourseName],
'database'[DueOnDate]
)
EVALUATE
FILTER (
'database',
'database'[StaffID]
IN VALUES ( NotCompliantTable[StaffID] )
)

Please accept as solution and give kudos if it helps

Hi, bpdax

Based on your description, you want to implement DAX statements that have similar functionality to SQL statements, and the following are possible DAX statements. If it does not work, you can share the data without sensitive information, the expected effect and the logic to achieve the effect. Feel free for anything about this.

VAR BaseTable = CALCULATETABLE( 'database'[table], 'database'[Compliant] = 0, 'database'[Team] IN @Team, 'database'[Course] IN @Course ) VAR SummaryTable = SUMMARIZE( BaseTable, 'database'[StaffID], "TrainingTracked", SUM('database'[TrainingTracked]), "DemNumDiff", SUM('database'[Denominator]) - SUM('database'[Numerator]), "TrackDemNumDiff", SUM('database'[TrackedDenominator]) - SUM('database'[TrackedNumerator]), "NotComplaint", IF( [TrainingTracked] = 16 && [TrackDemNumDiff] > 0, 1, IF([TrainingTracked] <> 16 && [DemNumDiff] > 0, 1, 0) ) ) VAR FinalTable = FILTER( SummaryTable, [NotComplaint] = 1 ) EVALUATE SELECTCOLUMNS( FinalTable, "StaffID", 'database'[StaffID], "Team", 'database'[Team], "FirstName", 'database'[FirstName], "LastName", 'database'[LastName], "CourseName", 'database'[CourseName], "DueOnDate", 'database'[DueOnDate] )

Thank you for your help. I managed to write a similar piece of code, I just changed the last part of the code to a NaturalLeftOuterJoin to get the rest of the things I needed.
