TypeError: not all arguments converted during string formatting in psycopg2

TypeError: not all arguments converted during string formatting in psycopg2

当我使用 psycopg2 运行 下面的代码时:

cur.execute(
    """INSERT INTO logmsg (msg_type, file, msg) VALUES %s;""",
    ["Error", str(file), str(sys.exc_info()[0])])

我收到以下错误:

TypeError: not all arguments converted during string formatting

有人可以帮我解决这个问题吗?

VALUES 需要用方括号括起来的值列表:

cur.execute(
    """INSERT INTO logmsg (msg_type, file, msg) VALUES (%s, %s, %s);""",
    ["Error", str(file), str(sys.exc_info()[0])])

不要忘记提交事务。
