# Every identifier in sql is quoted based on a comment in sqlite
# documentation &quot;SQLite adds new keywords from time to time when it
# takes on new features. So to prevent your code from being broken by
# future enhancements, you should normally quote any identifier that
# is an English language word, even if you do not have to.&quot;

def _iterdump(connection):

    Returns an iterator to the dump of the database in an SQL text format.

    Used to produce an SQL dump of the database.  Useful to save an in-memory
    database for later restoration.  This function should not be called
    directly but instead called from the Connection method, iterdump().
