尝试将用户输入插入SQL表时出错

Question

我遇到了问题，每当我试图运行下面的代码，选择语句2来，插入一个工具并放置一个随机的工具名，我就会得到错误消息：ProgrammingError(‘列“插入工具’不存在\n行1: insert tools(tool_name，rental_days)值(@insertTool，'2')。

以下是代码：

if Menu == "2":
  cursor = connection.cursor()
  InsertTool = raw_input("Please insert the tool that you want to add.\n")
  insert_tool = """insert into tools(tool_name, rental_days) values(@InsertTool, '2')"""  
  try:
     cursor.execute( insert_tool);
     connection.commit();
     print("Tool is succesfully inserted!")

  except Exception as e:
     connection.rollback();
     print("Exception Occured : ",e)
  connection.close(); 

Answer 1

尝尝这个。

if Menu == "2":
  cursor = connection.cursor()
  InsertTool = raw_input("Please insert the tool that you want to add.\n")
  insert_tool = """insert into tools(tool_name, rental_days) values(%s, %s)"""
  val = (InsertTool, "2")
  try:
     cursor.execute(insert_tool, val);
     connection.commit();
     print("Tool is succesfully inserted!")

  except Exception as e:
     connection.rollback();
     print("Exception Occured : ",e)
  connection.close();
