I'm using Oracle's SQL Developer.
For example, I've table City with two columns - place and speed_limit. Column speed_limit has datatype number(3) and I want query with select statement with return column speed_limit with units (mph) in the output in column speed_limit.
What I should add to the query?
SELECT speed_limit
FROM city;
to have output like this:
speed_limit
-----------
20 mph
40 mph
100 mph
instead of:
speed_limit
-----------
20
40
100
