java - ResultSet and the SQL functions -


i using derby database, , know something: resultset table? if so, means invoke min(resultset.somecolumn) (or max() or avg()), right? or have dump resultset temporary table use desired sql functions?

from official documentation , resultset is:

a table of data representing database result set, generated executing statement queries database.

if want apply aggregate function, have modify sql statement , re-execute it. finally, provided resultset (eventhough may contain single row).
