Starttheinstaller:

作了些试验,发现使用CLR的存储过程或函数在达到一定的阀值的时候,系统性能会呈指数级下滑!这是非常危险的!只使用几个可能没有问题,当一旦大规模使用会造成严重的系统性能问题!

不好!如果出了错;不好调试;不好处理!其实web开发将代码分为3层:web层;业务逻辑层和数据访问层;一般对数据库的操作都在数据访问层来做;这样便于调试和维护!而且将来如果是换了数据库的话;你只需要改数据层的代码;其他层的基本可以不变!要是你在jsp中直接调用sql数据库;那么如果换了数据库呢?岂不都要改?如果报了异常呢?怎么做异常处理?

是要和操作系统进行Socket通讯的场景。否则建议慎重!

但换公司用MSSQL2K感觉自己好像根本就不了解MSSQL。什么DTS触发器以前根本没用过。

个人感觉没有case直观。而且默认的第三字段(还可能更多)作为groupby字段很容易造成新手的错误。
