How do I use execute, rather than execute script in SQLite3?

Question

In the following code, scheduling.sql is executing properly, while dummy.sql is not. I'm not getting an error message. It just doesn't appear to be doing anything. For dummy.sql, I prefer to use execute, rather than executescript, so I can pass it some parameters. What am I doing wrong here?

db = sqlite3.connect(':memory:')
cursor = db.cursor()

with open('scheduling.sql', 'r') as sql_file:
    sql_script = sql_file.read()
cursor.executescript(sql_script)

with open('dummy.sql', 'r') as sql_file:
    sql_script = sql_file.read()
fetch=cursor.fetchone()
while fetch:
    cursor.execute(fetch)
    fetch=cursor.fetchone()

Answer 1

It never executes dummy.sql . What is fetch after fetch=cursor.fetchone() executes ? Guess is something falsey. fetch... comes after execute.... .
