I'm new to DAX and would like to do the following in DAX.
Select a1.accountNumber
From a1 Account, a2 Account
Where a1.AccountNumber == a2.AccountNumber AND a1.AccountDescription != a2.AccountDescription
I'm not really sure how to compare two columns from the same table in DAX. Assigning a table to a variable in DAX does not allow me to access the column in the variable.
Any help would be appreicated.

Hi @vega,
If I understand you correctly, you should be able to simply use the formula below to create new table to get number of AccountDescriptions for each AccountNumber.
Table = SUMMARIZE ( Account, Account[AccountNumber], "Number Of Description", DISTINCTCOUNT ( Account[AccountDescription] ) )
Then you can apply a filter to show only accounts which have the same AccountNumber, but different AccountDescriptions on the report.
Regards
Hi @vega,
Not really sure what you are aiming to do, do you have two tables in your model and pretend to have it a comparision between the two tables where the account number is equal but the description is diferent?
I created two table with two columns: account and Description
Then create a column in table 1 and put it on your visual and filter out the blanks values:
Comparision = IF ( LOOKUPVALUE ( Table2[Description], Table2[Account], Table1[Account] ) = Table1[Description], "", "Different Account Name" )
Result is below:
Not sure if this is what you are looking for.

Check out my blog: Power BI em PortuguêsI have one table, Accounts. And I want to return all the account which have the same AccountNumber, but different AccountDescriptions. Is it possbile to do this comparison on only one table? I know in SQL I can create an alias for the same table and then do the comparison that way.

I went ahead and marked the above as the solution. I'm sure it's not ideal, as it requires you to make a second table, which requires more space. I was able to solve the problem a different way by using calculated columns. In case anyone is interested the calculated column is as follows:
= NOT( ISEMPTY( FILTER(Query1, [AccountNumber] = EARLIER([AccountNumber]) && [AccountDescription] <> EARLIER([AccountDescription])) ) )
This will create a calculated column where the value is TRUE when the AccountNumber has an identical AccountNumber, but with a different AccountDescription and FALSE if there are no other AccountNumbers which are the same with different AccountDescriptions. I perfer this method as it adds one column. I could not figue out how to get this done as a Measure.
P.S.
Thank you for all of your help I greatly, greatly appreciate it.
