I’m not familiar with doing SQL like that. I get that you want me to put in that SQL statement.. little details I don’t get exist.. 

Like do you include that comma in the first line? 

And what would this do?

And is “having” a SQL command word, usually capitalized?

Do I fetch into a list?

What should I expect to see?

Sorry
