Sql 两列均为true时不显示数据的情况

我有两列IsHomeDelivery和Ispurchase，它们的值可以是0和1

当值为1时，我必须显示文本

表示当IsHomeDelivery=1时，则为“送货上门” ispurchase=1，然后为“购买”

我提出以下质疑：

SELECT
        LocationName,
        BranchName,
        AddLine1,
        AddLine2,
        Tel1,
        CASE
            WHEN LocationType='CC' THEN 'Call Center'
            WHEN LocationType='CL' THEN 'Operation'
        END AS 'Location Type',
        CASE
            WHEN IsPurchase= 1 THEN 'Purchase'
            WHEN IsHomeDelivery = 1 THEN 'Home Delivery'
            WHEN IsPurchase=1 AND IsHomeDelivery=1 THEN 'Purchase And Home Delevery'
        END AS 'Type'
    FROM PescaLocation

但不幸的是，这对两个专栏都不起作用

是指当iHomeDelivery和iPurchase均为1时，则显示“购买”，而应显示“HomeDelivery和purchase”

请帮帮我

在第二种情况下，您缺少一个条件。当IsPurchase和IsHomeDelivery均为1时，“When IsPurchase=1”将为真

这是更新后的代码

select LocationName
    ,BranchName
    ,AddLine1
    ,AddLine2
    ,Tel1
    ,case 
        when LocationType = 'CC'
            then 'Call Center'
        when LocationType = 'CL'
            then 'Operation'
        end as 'Location Type'
    ,case 
        when IsPurchase = 1 and IsHomeDelivery = 0
            then 'Purchase'
        when IsPurchase = 0 and IsHomeDelivery = 1
            then 'Home Delivery'
        when IsPurchase = 1 and IsHomeDelivery = 1
            then 'Purchase And Home Delevery'
        end as 'Type'
from PescaLocation
