在Odata查询的$ expand中使用$ filter [英] using the $filter inside the $expand in the Odata query

问题描述

我正在尝试使用Odata查询之类的扩展实体来使用过滤器

I am trying to use the filter in the expanded entity using the Odata query like

   https://labstest.science.com/DEV/odata/ROOM_REQUEST?$expand=REQ_COLONYROOM($select=Name;$filter=Name eq 'RB05')

这部分起作用.对于名称不等于RB05的REQ_COLONYROOM，它将所有ROOM_REQUEST带空值

This works partially. It brings all the ROOM_REQUEST with Null for the REQ_COLONYROOM where Name is not equal to RB05

{
"@odata.context": "https://labstest.science.com/DEV/odata/$metadata#ROOM_REQUEST(REQ_COLONYROOM(Name))",
"value": [
    {
        "Id": 18399308,
        "Name": "M1",
        "Barcode": "M1",
        "REQ_COLONYROOM": null
    },
    {
        "Id": 18403071,
        "Name": "M2",
        "Barcode": "M2",
        "REQ_COLONYROOM": {
            "@odata.id": "https://labstest.science.com/odata/COLONY_ROOM('MC19')",
            "Name": "RB05"
        }
    },
    {
        "Id": 18403109,
        "Name": "M3",
        "Barcode": "M3",
        "REQ_COLONYROOM": null
    }]}

尽管M1和M3与RB05具有不同的菌落，但它通过odata调用返回Null

Though M1 and M3 has different Colony than RB05 it returns Null with the odata call

推荐答案

您是否尝试过以下方法:

Did you try something like this:

 https://labstest.science.com/DEV/odata/ROOM_REQUEST?$expand=REQ_COLONYROOM&$select=REQ_COLONYROOM/Name&$filter=REQ_COLONYROOM/Name eq 'RB05'

我认为没有SELECT就足够了

I think it would be enough not having SELECT:

 https://labstest.science.com/DEV/odata/ROOM_REQUEST?$expand=REQ_COLONYROOM&$filter=REQ_COLONYROOM/Name eq 'RB05'
