I'm pretty new to SQL so forgive me if this is extremely easy--I couldn't find an answer by searching the forum or Google. I have a binary variable that I want to recode to make it more user-friendly to my client. The column is essentially saying, "Did the customer make a purchase?" and the variables are either 0 for no or 1 for yes. What I want to do is write into SQL that 0 displays as No and 1 displays as Yes. How would I do this? I'm using Oracle SQL Developer.
