Comparison operator saved in Cell - How to use?

[nellyvk]

Hi all,

I have two columns that I need to compare and the comparison operator is saved in a third column. I am not sure how to write the query to use the operator that is saved in the cells 

I tried using COMBINEVALUES but it return the whole thing as a string, rather than doing the operation

Any suggestions?

Hi @nellyvk 

Thanks for the reply from @amitchandak , please allow me to provide another insight:

I create a set of sample:

Then add a calculate column:

Column =
SWITCH (
    TRUE (),
    'Table'[Value1] > 'Table'[Value2]
        && FIND ( ">", 'Table'[Operator],, BLANK () ) <> BLANK (), "True",
    'Table'[Value1] = 'Table'[Value2]
        && FIND ( "=", 'Table'[Operator],, BLANK () ) <> BLANK (), "True",
    'Table'[Value1] < 'Table'[Value2]
        && FIND ( "<", 'Table'[Operator],, BLANK () ) <> BLANK (), "True",
    "False"
)

 The result is as follow:

@nellyvk , Try Expression.Evaluate in power query

New column in power query, assuming you have three columns with col2 as CheckParameter

Expression.Evaluate([Col1] & " " & [CheckParameter] & " " & [Col3])
