我们现在收到价值参数,即<代码>VARCHAR,然后从这些数值中确定一个日期。 我愿确认,以下方法将阻止在声明中注入库克的可能性:
select CONVERT(datetime, 2010 + - + 02 + - + 21 + + 15:11:38.990 )
另一项说明是,通过储存的代谢通过的实际参数受限为<代码>(4、2、10、12)VARCHAR。

如果你在储存的程序中使用这样的声明:
select CONVERT(datetime, @Year + - + @Month + - + @Day+ + @Time)
那么,由于目标数据类型<代码> 日期代码>将只收到有效的日期指示,你应当被罚款。
如果您在所储存的程序中利用了这一方法:
EXEC ( select CONVERT(datetime, @Year+ - +@Month+ - +@Day+ + @Time) )
你们可能有一个问题,不大可能,因为投入范围有限,但谁知道一些黑客会想到什么适合这个小空间。
如果该声明是存储程序,那么你就会获得q的注射。
例如,如果用一种语言—— php——来发表这一声明,那么,仅仅确保你逃脱在路上(用我方言或用ms)的扼杀,以避免注射攻击。
