Select a column of a FILTER result

 

So, I have these tables:

 

THPayments : [id, SK_DATE, amount, reference, currency_id]

DimCurrencies: [id, name ]

DimCurrenciesRates: [id,currency_id,SK_DATE,conversion_date]

 

THPayments[currency_id] is related to DimCurrencies[id]

DimCurrenciesRates[currency_id] is related to DimCurrencies[id] 

 

I want to get the Conversion_rate for the Date of my payment with the actual currency id.

 

Explained in SQL woulb be like:

 

SELECT conversion_rate FROM DimCurrenciesRates

WHERE 

conversion_rate.SK_DATE = THPayments.SK_DATE

and

conversion_rate.currency_id = THPayments.currency_id

 

 

The best I could do was, on the THPayments table, create a calculated column with:

 

=FILTER(DimCurrenciesRates;DimCurrenciesRates[SK_DATE] =[SK_DATE] && [currency_id] = DimCurrenciesRates[currency_id])

 

This effectibly returns the row i want, but, its a full row, i just need the "conversion_rate" value. Of course the error is:

 

"The expression refers to multiple columns. multiple columns cannot be converted to a scalar value"

 

How could I do this? Thanks!

Re: Select a column of a FILTER result

GOT IT!

 

I just had to SUMMARIZE the FILTER result:

 

=SUMMARIZE(

FILTER(DimCurrenciesRates;DimCurrenciesRates[SK_DATE] =[SK_DATE] && [currency_id] = DimCurrenciesRates[currency_id]);

DimCurrenciesRates[conversion_rate] )

 

Thanks!
