推荐答案

您不引用占位符.这会将它们转换为字符串，而不是占位符:

You don't quote placeholders. That turns them into strings, not placeholders:

... VALUES(:id_facebook, :nome, :email)
                         ^----^-^-----^--- note the lack of quotes

是所有必需的

占位符的全部目的是消除引用/转义的任何需要.数据库引擎会为您完成所有这些工作.

The whole point of placeholders is to remove any need for quoting/escaping. The DB engine takes care of all that for you.
