I'm getting this error no matter what with python and sqlite.

  File "addbooks.py", line 77, in saveBook
  conn.commit()
  sqlite3.OperationalError: cannot commit transaction - SQL statements in progress

The code looks like this:

    conn = sqlite3.connect(fname)
cread = conn.cursor()

cread.execute('''select book_text from table''')
while True:
    row = cread.fetchone()
    if row is None:
        break
    ....
    for entry in getEntries(doc):
        saveBook(entry, conn)

Can't do a fetchall() because table and column size are big, and the memory is scarce.

What can be done without resorting to dirty tricks(as getting the rowids in memory, which would probably fit, and then selecting the rows one by one)?.
