minus-squareJackbyDevlinkfedilinkEnglish21•7 months agoWhy would there be an age and my_age column on the table GIRLS?
minus-square@[email protected]linkfedilink15•7 months agoGood point. Should be age > (@my_age / 2) +7 FTFOP - now my age is some value defined outside the immediate query. More likely, the GIRLS would be a view of some table persons and you could query my_age from that table too.
minus-square@[email protected]linkfedilink-1•edit-27 months agoThank you. I assumed the reader would be educated enough to guess I meant a variable. But yeah, should used @my_age
minus-square@[email protected]linkfedilink3•7 months agoPretty sure “People who know enough about SQL to know about variables” is a subset of “People who know enough about SQL to be pedantic about it” :p
minus-square@[email protected]linkfedilink8•7 months agoBecause for each girl you meet, you might tell her a different age.
minus-squareJackbyDevlinkfedilinkEnglish2•7 months agoAh, but if we care at all about normalization and that’s calculatable from the other columns (it should be) then it shouldn’t be a column. Unless it’s expensive and this is a view, of course.

A fair point :D
