I think you can just use OR:
SELECT *
FROM table
WHERE (input = '' OR input = ?)
This is assuming that `input` is a column in your table and ? is the
user input, based on the query you provided. But are you sure that's
what you mean?
Also, if the `input` column can contain nulls you might also want:
SELECT *
FROM table
WHERE (input IS NULL OR input = '' OR input = ?)
