actually, it isn't, or perhaps i should say wasn't *

technically, it has always been about ~ standard SQL~

it just happens to be located on the oracle site, one of many "vertical"
(how i hate that word) sites within the techtarget.com family of sites

it began as a column at "searchdatabase.com" but this site was later
subsumed, and, after techtarget decided to focus on technology (rather than
technique, which is what i teach), my column happened to end up under the
oracle umbrella, a really lousy decision from my point of view because i
kept having to fend off oracle-specific DBA type questions and answer only
the dbms-agnostic ones

* after 8 years and almost 700 SQL answers, techtarget has decided to cancel
the column, but you can find links to all the answers at
