配置数据集的输出字段是指对数据集中已有的字段进行进一步的配置,比如控制字段的显示与否、为字段添加别名、添加自定义字段或者添加分组统计等。
通过对字段的这些配置操作,可以进一步增强数据集的实用性,更加方便后续的数据分析与展示。
Wyn 提供了两种视图模式来配置输出字段,分别为详情视图和分组视图,在这两种视图模式下可以进行不同的配置操作。
详情视图模式下,会将数据表中的所有字段都显示出来。您可以在此视图下配置最终的结果集中显示哪些字段、更改字段的数据类型、为字段取别名等,还可以在原有字段基础上添加自定义字段。
分组视图模式下,您可以使用数据表中的原有字段,新建 Sql 字段或计算字段对数据进行分组和聚合。
本章节为您介绍在详情视图模式的具体怎样配置明细字段。
下一章节(配置分组聚合字段)为您具体介绍如何进行分组聚合。
