Question

人员的送货地址中包含多个文本，例如在此4行消费者地址中。

     |         Address Line                 |
     |--------------------------------------|
     |APARTMENT 5800 springfield GARDENS CIR|
     |--------------------------------------|
     |APT 5800 springfield GARDENS CIR      |
     |--------------------------------------|
     |2567 south pay street                 |
     |--------------------------------------|
     |Office 222 Market , VA 048946         |

如何添加包含某些字符的其他列，例如Address Line包含＆＃34; Apartment＆＃34;或者＆＃34; APT＆＃34;将成为＆＃34;公寓＆＃34;并且Address Line包含＆＃34; Street＆＃34;将成为＆＃34;家庭＆＃34; ，Address Line包含＆＃34; Office＆＃34;将成为＆＃34;办公大楼＆＃34;和＆＃34;未知＆＃34; Address Line未包括在内。

这是PostgreSql

附带的查询后的所需表格

         |         Address Line                 |      Location      |
         |--------------------------------------|--------------------|
         |APARTMENT 5800 springfield GARDENS CIR|   Apartement       |
         |--------------------------------------|--------------------|
         |APT 5800 springfield GARDENS CIR      |   Apartement       |
         |--------------------------------------|--------------------|
         |2567 south pay street                 |   Household        |
         |--------------------------------------|--------------------|
         |Office 222 Market , VA 048946         |   Office building  |
         |--------------------------------------|--------------------|

这是我的疑问：

 SELECT ORDER_TABLE.guest_email,
        CASE WHEN ORDER_SHIPPINGADDRESS.LINE1 IN ('Apartement', 'apt') Then 'Apartement'
        WHEN ('street') then 'household'
        WHEN ('Office') then 'Office Building'
        ELSE 'Location Unknown' END as Location

到目前为止，我使用Case When进行了试用，但结果是这样的错误

ERROR: argument of CASE/WHEN must be type boolean, not type record

是否有任何功能可以执行上面所需的表格？感谢

Answer 1

您应该在每个WHEN

中重复ORDER_SHIPPINGADDRESS.LINE1 IN

SELECT ORDER_TABLE.guest_email,
    CASE WHEN ORDER_SHIPPINGADDRESS.LINE1 IN ('Apartement', 'apt') Then 'Apartement'
         WHEN ORDER_SHIPPINGADDRESS.LINE1 IN ('street') then 'household'
         WHEN ORDER_SHIPPINGADDRESS.LINE1 IN ('Office') then 'Office Building'
    ELSE 'Location Unknown' END as Location

替换String在Postgresql中包含多个字符串
