    Try this:

     

    CompletedQuery = COUNTX(FILTER('TraceData',TraceData[EventClass] = "RPC:Completed" || TraceData[EventClass] = "SQL:BatchCompleted"), TraceData[EventClass])

Hi, thanks for your reply. The EventClass data type is text.

 

I tried wrapping a value statement arount the column but got error 'Function CONTAINSROW does not support comparing values of type text with values of type number.

 

I did also try the countax function and although it parsed successfully, the filter didn't work and returned every row.

 

I am simply trying to count all rows where EventClass is either 'RPC:Completed' or 'SQL:BatchCompleted'

Try this:

 

CompletedQuery = COUNTX(FILTER('TraceData',TraceData[EventClass] = "RPC:Completed" || TraceData[EventClass] = "SQL:BatchCompleted"), TraceData[EventClass])

    Hi, is there a soution to take the unique values from your expression: 

    FILTER('TraceData',TraceData[EventClass] = "RPC:Completed" || TraceData[EventClass] = "SQL:BatchCompleted")

    The filter returns a table and I want to count the unique values.

    Thanks,
