字段子字符串的 OData 选择语法 [英] OData Select Syntax for Field SubString

问题描述

我正在为列表提取数据.OData 语法中有没有办法只提取字段的前 100 个字符.例如EmployeeDescription 字段，我只想显示 Nvarchar(1000) 数据库字段的前 100 个字符.

Im pulling data across the line for a listing. Is there a way in OData syntax to only pull the first 100 characters of a field. e.g. EmployeeDescription field, I only want to show the first 100 characters of a Nvarchar(1000) database field.

我正在努力减少越过这条线的尽可能多的数据.

Am trying to cut down as much as possible data going across the line.

谢谢

推荐答案

目前不支持此类查询.投影功能 ($select) 只允许您选择要获取的属性，但您将始终获取整个属性值.

Currently there's no support for such query. The projections feature ($select) only allows you to select which properties to get, but you will get the entire property value always.
