minus-squareJackbyDev@programming.devlinkfedilinkEnglisharrow-up0·6 days agoWhy would there be an age and my_age column on the table GIRLS?
minus-squarejol@discuss.tchncs.delinkfedilinkarrow-up0·6 days agoBecause for each girl you meet, you might tell her a different age.
minus-squareJackbyDev@programming.devlinkfedilinkEnglisharrow-up0·6 days 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.
minus-squarelennivelkant@discuss.tchncs.delinkfedilinkarrow-up0·6 days 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-squarefibojoly@sh.itjust.workslinkfedilinkarrow-up0·edit-26 days agoThank you. I assumed the reader would be educated enough to guess I meant a variable. But yeah, should used @my_age
