Hi All,
I have been experimenting with the web-based development workbench for SAP Hana based on the following and the youtube video of Thomas Jung:
"Develop Your First SAP HANA Native Application
on SAP HANA Platform Using the SAP HANA
Web-based Development Workbench
Version 1.1 | March 2014 | Bertram Ganz, Jens Glander | SAP AG"
I then wanted to extend it to try the "Update" and "Deletion" extension of the XSODATA.
Thus, my data model:
namespace dev.devuser00.perslist.data;
@Schema: 'devuser00_perslist'
context mymodel {
type SString: String(60);
@Catalog.tableType: #COLUMN
Entity person {
key ID: String(10); // element modifier 'key' defines that ID is primary key
FIRSTNAME: SString;
LASTNAME: SString;
};
context procedures{
type pers {
ID: String(10);
FIRSTNAME: SString;
LASTNAME: SString;
};
type persNames {
FIRSTNAME: SString;
LASTNAME: SString;
};
type errors {
HTTP_STATUS_CODE : Integer;
ERROR_MESSAGE : String(100);
DETAIL : String(100);
};
};
};
My XSODATA: person.xsodata
service {
"dev.devuser00.perslist.data::mymodel.person" as "Persons"
create using "dev.devuser00.perslist.procedures::createPerson";
update using "dev.devuser00.perslist.procedures::updatePerson"
delete using "dev.devuser00.perslist.procedures::deletePerson";
}
The service is not activated because of the update procedure (Even when bypassing the update, the delete does not work):
Error while activating:
Invalid procedure or parameter list in procedure "dev.devuser00.perslist.procedures::updatePerson".
Here is the update procedure:
PROCEDURE
"devuser00_perslist"."dev.devuser00.perslist.procedures::updatePerson" (
IN intab "devuser00_perslist"."dev.devuser00.perslist.data::mymodel.procedures.persNames",
OUT outtab "devuser00_perslist"."dev.devuser00.perslist.data::mymodel.procedures.errors"
)
LANGUAGE SQLSCRIPT
SQL SECURITY INVOKER
DEFAULT SCHEMA "devuser00_perslist"
--READS SQL DATA AS
AS
begin
declare lv_firstname string;
declare lv_lastname string;
select FIRSTNAME, LASTNAME into lv_firstname, lv_lastname from :intab;
if :lv_lastname = '' then
outtab = select 500 as http_status_code,
'Invalid last name ' || lv_firstname as error_message,
'No Way! Last name field must not be empty' as detail from dummy;
else
update "dev.devuser00.perslist.data::mymodel.person"
set FIRSTNAME = lv_firstname, LASTNAME = lv_lastname
where LASTNAME = lv_lastname;
end if;
end;
I have also attached the perslist.controller.js, the perslist.view.js and the index.html.
I am in SP 7.
Can anyone plase have any clue ?
Many thanks in advance.
