C# 7 out variables, tuples & other new features C# 7 is available on new Visual Studio 2017 and comes with some new features. I wouldn’t call them ‘revolutionary’ features, but they add on the language very well and some of them can be very helpful.…

一.动态分区的好处就不说了,随着时间的推移,不可能一个度量值组都放在一个分区中,处理速度非常慢,如何动态添加分区,如何动态处理分区,成为了很多新手BI工程师一个头痛的问题,废话不多说,分享一下我的经验. 二.首先讲一下大致的流程,主要是通过SSIS进行任务的处理,本文主要是按照月进行分区,当然分区的规则大家可以根据自己的需求制定. 该包用到的所有变量 三.对上面四个步骤分别讲解一下. 1.得到所有分区: ①.主要设置如下图 ②.输出的结果集应该传给变量Partitions ③.SQLStatem…

1. Multiple features(多维特征) 在机器学习之单变量线性回归(Linear Regression with One Variable)我们提到过的线性回归中,我们只有一个单一特征量(变量)--房屋面积x.我们希望使用这个特征量来预测房子的价格.我们的假设在下图中用蓝线划出: 不妨思考一下,如果我们不仅仅知道房屋面积(作为预测房屋价格的特征量(变量)),我们还知道卧室的数量.楼层的数量以及房屋的使用年限,那么这就给了我们更多可以用来预测房屋价格的信息. 即,支持多变量的假设为:…
