named parameter

基本解释

The request URI can be retrieved as well as the argument values of named parameters.
我们可以获得请求的URI以及参数的名值对。
If you use named parameters, your SQL statement might look like this, with a list of named variables holding the values to be inserted
如果使用命名参数，SQL 语句将带有一系列包含插入值的命名变量，类似于
Finally, another constraint on named parameters is that once you provide a name for a parameter in a method invocation, then the rest of the parameters appearing after it must also be named.
最后，还有一个对命名参数的约束就是一旦你为一个方法掉哦那个指定了参数名称，那么剩下的在这个参数之后的所有参数都必须是命名参数。
