Yes, but it doesn't work with this wrapper (APSW version 3.5.9-r1):

I'm getting an error when doing it this way:

=======
isbn = "123"
sql = "SELECT COUNT(*) FROM books WHERE isbn='%s'"

#Incorrect number of bindings supplied.  The current statement uses 0
and there are 1 supplied.  Current offset is 0
cursor.execute(sql, (isbn,))
=======

I don't know enough about Python and this wrapper to tell why it
triggers an error.

>> you want:

>>         if not count:

This wrapper doesn't seem to support fetchone():

=====
#AttributeError: 'apsw.Cursor' object has no attribute 'fetchone'
row = cursor.fetchone()
=====

This works, though:
========
	cursor.execute(sql)
	for row in cursor.execute(sql):
		#Record not found -> Insert
		if not row[0]:

========

Thank you.
