基本介绍

功能概述

单击字段列表进入字段配置页面,单击页面右上角的详情分组可切换视图(截图以直连数据集为例)。

type=warning

注意

两种视图之间进行切换时会丢失当前的设置,请您谨慎操作。

详情视图

默认是在详情视图下。

image

image2019-1-24_11-18-12.png 可以通过在搜索框中输入关键字来快速查找字段。

image2019-1-24_11-18-56.png 单击可以展开或收起当前数据表。当有多个表时,可以帮助您快速切换到其他表找到需要的字段。

字段 : 数据表中原始的字段名。

输出 : 控制字段的输出情况,即控制字段在最终的结果集中是否显示。勾选则会显示,反之不会显示。仪表板数据集的输出字段数建议不超过30个,以防影响系统的计算性能。

类型(目标类型): 修改字段的数据类型,修改后在使用时将按新的类型使用。

数据类别: 用于指定数据类别,用于仪表板中的图片解析或地图位置识别。

别名 : 字段别名,单击对应字段的别名区即可为该字段输入别名。数据集优先显示字段别名,无字段别名时,将会显示原始字段名。

描述 : 单击对应字段的描述区即可为该字段添加备注或描述,描述不会在数据集中显示出来。

image2019-1-22_17-26-23.png 单击可添加自定义字段,具体操作方法请见后续内容添加自定义字段。

快速生成别名

如果使用 SQL Server 或 PostgreSql 数据源创建数据集,那么在详情视图界面的右上角会有一个快速生成别名的按钮。

单击按钮则可以将数据库中描述字段属性值生成字段的别名。如下图:

注意

这里需注意,生成别名时并不是使用的“描述”中的字符,而是直接取的数据库中的 MS_Description/Comment属性值。

因此即使您在数据集字段列表中修改了“描述”,自动生成别名时也不会受影响。
