类型错误字符串指数必须为整数时pyodbc

Question

试图使用功能使用pyodbc在MSSQL查询数据时，我有一个麻烦

函数中执行查询，功能：

def getUserList(connection): 
    li = [] 
    cur = connection.cursor() 
    query = 'select username, password, firstname, lastname, description, phone,'+ 
      'email, isAdmin, isAutoBoot from users_tbl'  
    cur.execute(query) 
    for usr, pwd, fn, ln, des, ph, em, ad, au in cur.fetchall():   
     temp = User(usr, pwd, fn, ln, des, ph, em, ad, au)    
    cur.close() 
    #con.close() 
    return li 

当我导入模块和运行该功能，遇到类型错误：

Traceback (most recent call last): 
File "<pyshell#71>", line 1, in <module> 
    import_user.getUserList(s_con) 
File "c:/python27/mymodule\import_user.py", line 12, in getUserList 
    cur.execute(query) 
TypeError: string indices must be integers 

但是，如果我复制并运行这些线在Python IDLE的，它运行良好，没有错误时，执行光标。它发生在我传递pyodbc或sqlite连接作为输入参数时。

感谢

要解决语法问题，改变这些行：

query = 'select username, password, firstname, lastname, description, phone,'+ 
     'email, isAdmin, isAutoBoot from users_tbl' 

或者（换行不保留）：

query = ('select username, password, firstname, lastname, description, phone, ' 
     'email, isAdmin, isAutoBoot from users_tbl') 

或（新行保留）：

query = """select username, password, firstname, lastname, description, phone, 
      email, isAdmin, isAutoBoot from users_tbl"""
