Hi, I can specify the text used to represent a null value in output from copy, but I'd like to do something similar is select output, eg: all NULL values are represented by NA or NaN. I can't find anything in the docs about this. This could be managed using case statements around all the columns in the query, but is there a simpler way, like setting a system variable to specify this?
