postgresql - 尝试将用户的输入插入 SQL 表时出错

Question

我遇到了问题，每当我尝试运行下面的代码并选择语句 2 以插入工具 并输入随机工具名称时，我都会收到错误消息:ProgrammingError ('column "inserttool' does not exist\nLine 1: insert tools(tool_name, rental_days) values(@insertTool, '2') .

代码如下:

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

试试这个。

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();
