另外一个函数sendstockalert会向某个e -mail地址发送消息(e - mail地址和发送的消息都可以由用户定义)。
In order to do this, the basic idea is to create a combined user-defined function that first invokes the model creation process and that then extracts the rules and returns them as a result set.
以此为目的，基本的想法是创建一个用户定义组合函数，此函数首先调用模型创建过程，之后再提取规则并将这些规则作为结果集返回。
In such cases, it's usually a good idea to refactor the code out into a user-defined function, which the key-mapping can then call.
在这种情况下，通常最好将代码重构为一个用户定义的函数，键映射随后就可以调用该函数。
This namespace declaration is required for any application that USES the library since the user-defined function has to be in a certain namespace.
