T SQL to DAX conversion

Hello Everyone,

 

I am new to PowerBI. I am trying to convert this sql to DAX.

I am not getting any success.

I am trying to create a calculated colum that calculates the number of time "(-)" is present in the Deltas column for each row.

 

Here is my SQL:

 

Select

[Deltas]

,COUNTDeltas = (LEN(Deltas) - LEN(REPLACE(Deltas, '(-)', '')))/LEN('(-)')

From MyTable

 

Please assist.

 

thank you so much!

It looks like you can use the LEN function and the SUBSTITUTE function to create your COUNTDeltas column.

You should be able to get a pretty direct transation from your T-SQL:

 

(LEN([Deltas]) - LEN(SUBSTITUTE([Deltas], '(-)', ''))) / LEN('(-)')
