sqlite3没有刷新表

Question

conn = sqlite3.connect('./mydb.db')
c = conn.cursor()
with open('./mydb_tmp.sql', 'w') as f:
    for row in c.execute('SELECT * FROM FLOWS'):
        print >>f, row
c.execute('DELETE FROM FLOWS;')
conn.close()

之后，所有行仍然在mydb

您需要提交命令。

    fn give<S>(&self, x: S) -> S 
    where S: Limit
