Convert SQL into DAX

To convert the SQL code to DAX, you can try the following approach:

Replace the FROM and JOIN clauses with a FILTER function that filters the rows in the relevant tables based on the conditions in the WHERE clause.

Replace the SELECT and COUNT clauses with a CALCULATE function that counts the distinct AccountNumber values using the DISTINCTCOUNT function.

Here's the resulting DAX measure:

Count of Distinct Account Numbers =

CALCULATE(

DISTINCTCOUNT(dimAccount[AccountNumber]),

FILTER(

factTable,

factTable[DateSk] = dimDate[DateSk]

&& dimDate[IsLastDayOfMonth] = 1

&& dimDate[DateKey] > "2020-11-30"

&& dimDate[DateKey] <= "2021-11-30"

&& ISBLANK(factTable[Sale])

&& factTable[IsDeleted] = FALSE

&& dimAccount[IsDeleted] = FALSE

),

FILTER(

dimAccount,

dimAccount[AccountKey] = factTable[AccountKey]

&& dimAccount[DateSk] = factTable[DateSk]

)

)

This measure should give you the same result as the SQL query.

Note: I replaced ISNULL(F.Sale ,0) = 0 with ISBLANK(factTable[Sale]) since DAX doesn't have an ISNULL function. In DAX, you can use the ISBLANK function to check if a value is NULL or an empty string.

I hope this helps! Let me know if you have any questions or if you need further assistance.
