    Using SQL then the following query should work..

    Assuming the Param fields are ints use cast to make them strings

    UPDATE Table1 SET Multiplication = CAST(Parameter1 AS VARCHAR(10)) + '_' + CAST(Parameter2 AS VARCHAR(10))

    Else if they are already strings (e.g., varchar, text) just don’t cast. I.e.,

    UPDATE Table1 SET Multiplication = Parameter1 + '_' + Parameter2

    Just change Table1 to the name of your table
