I'd like to be able to determine which unit of measure to concatenate to a value by using a decode statement in the query. I have a column in the database that stores time in minutes, and I'd like to be able to show the output in minutes if the value is less than 60, but in hours (such as 3.27 hours) if the value is greater than 60. So far I've tried the following statement, but it seems to be blowing up on the first comparison operator:
