select (clj)
(source)function
(select & exprs)
Accepts any number of column names, or column/alias
pairs, or SQL expressions (optionally aliased):
(select :id [:foo :bar] [[:max :quux]])
Produces: SELECT id, foo AS bar, MAX(quux)
The special column name :* produces * for 'all columns'.
You can also specify :t.* for 'all columns' from the
table (or alias) t.
