odata 服务忽略 sql 视图中的排序定义（SAP HANA 云平台）

Question

My first step to learning SAP HANA was usage of odata services related to database tables and database views. I created the XS Project, then a database table, fill it with content and then created the sql view and definded simple odata service topowners.xsodata . The sql view was grouped and ordered. If i call (in Eclispe or WebIDE) the sql view "display content" , the entries are correct ordered by defined attribute.

If is call the odata service in XS Service (in browser) the entries are NOT ordered by defined attribute. How do I solve the problem? Thank you

odata Service definition

service { 
"DB_XS"."SUM_VIEW" as "TopOwners"
key  ("owner_code") 
    create forbidden
    update forbidden
    delete forbidden;
}

sql view definition

CREATE VIEW "DB_XS"."SUM_VIEW" ( "owner_code",
     "owner_count"
) AS select
     owners."owner_code" ,
     SUM("current_owner_cnt") as "owner_count"  

from "DB_XS"."owners" owners 

group by owners."owner_code"  

order by "owner_count" desc 
     p WITH READ ONLY

Answer 1

You can solve the problem by adding a $orderby in your oData request:

 http:// ... /topowners.xsodata/TopOwners?$orderby=owner_count

See here for example
