EXCEL|Power Query应用之动态查询
今天的内容是：根据以下2个表格的内容，从左表中查询出全部购买右边紧俏商品的客户。这里需要特别注意的，就是全部二字。购买过，但不是全部的不在选择之列。
今天的内容，没有需要特别修改公式的地方。用到的主要是合并查询，要特别注意合并查询里选择的连接种类。关于连接种类，咱们前面专门讲过，看这里，在最后。
1）把客户查询和紧俏商品2个表格分别导入到查询编辑器里。然后复制下客户查询表格，命名为非紧俏商品。这样做的目的是识别出非紧俏商品，然后后面进一步识别出购买过非紧俏商品的客户。选择非紧俏商品表格，然后合并查询紧俏商品。这里的匹配列是商品名称，连接种类是左反（保留第一个表格里跟第二个表格不匹配的行），见以下操作。
2）得到如下结果。这个表格操作完成。
3）选择查询客户表格，合并查询非紧俏商品表格，这里匹配的是客户编号，连接种类还是左反，目的是删掉那些买过非紧俏商品的客户。操作如下图所示。
4）结果如下图所示。
5）因为只是要识别出客户编号，所以可以直接删除后面的3列，然后删除重复的客户编号，结果就出来了，如下图所示。这基本就是我们想要的最终结果了。

今天的内容也比较简单，大概总结下：1. 第一个合并查询是为了识别出非紧俏商品，所以选择查询的匹配列是商品名称；2. 第二个合并查询是为了识别出购买过非紧俏商品的客户，所以查询的匹配列是客户编号；3. 因为2个查询都是相斥查询，所以选择的都是左反。

好的，今天的内容就这样。
