Hey - - -- -
Risking foolish exposure once again:
Typical SQL I (we all?) learned like this (way-pseudo code):
select ppl.last, ppl.first,ppl.nickkiename,ppl.shoesize,ppl.egosize,
loca.adr1,loca.adr2,loca.city,loca.state,loca.zip,
tran.tdate,tran.tamount,tran.duedate,tran.quan,
product.priceeach,product.pname,product.pcategory
from ppl inner join loca
on ppl.loc_id = loca.loc_id
inner join tran
on tran.per_id = ppl.per_id
inner join product
on tran.prod_id = product.prod_id
where
ppl.first = "Esmerelda"
and
tran.duedate > date()
and
product.pcategory = "Flubber"
I saw an example posted here (by Ted?) where some of the selection
criteria were mixed in with the JOIN statements, like this:
...from ppl inner join loca
on ppl.loc_id = loca.loc_id
AND ppl.first = "Esmerelda"
inner join tran
on tran.per_id = ppl.per_id
AND tran.duedate > date()
inner join product
on tran.prod_id = product.prod_id
AND product.pcategory = "Flubber"
Questions:
- In what situations does this make sense? (or Not)
- What are the advantages?
"Anyone? Anyone?" (Knock, knock -- anyone still thinking on Friday
afternoon?)
