(metalanguage)   if input is provided, then query("SELECT stuff FROM
table WHERE whatever = $INPUT")
                                           else, query("SELECT stuff
FROM table")

in other words, make the decision as to what query to execute OUTSIDE of
sql by invoking different queries based on your application's 'input'.
