我试图弄清楚为什么我在 python 中的测试程序不起作用。我可以从 MySql Workbench 很好地访问数据库,我认为我在编程部分做的一切都正确,我还去了管理工具并将我的数据库添加到 ODBC 数据库源,这是我的测试程序,如果有人能弄清楚是什么错误的:
import pypyodbc
conn = pypyodbc.connect("DSN=database")
def func():
l = []
cur = conn.cursor()
try:
cur.execute("SELECT foo FROM table")
except pypyodbc.DatabaseError:
pass
conn.commit()
for i in cur:
l.append(i)
conn.close()
cur.close()
func()
我得到的错误是:
Traceback (most recent call last):

File "D:/path/test.py", line 14, in func
for i in cur.fetchall():
