Re: Manage multi-table insert using OData Service

Hi Srihari,

1)===>>>Multiple table CRUD operations are not possible, but we can give read operations for UI5 and we can able to create multiple table by using NAVIGATE and ASSOCIATION........and i was refer many blocks for CRUD operations but no solutions so i decided and created one procedure which is for CREATE / UPDATE procedure .the given procedure is execute both CREATE and UPDATE

operations i was tested in ODATA its working fine but conditions should be based on primary keys and related bussiness logic.

2) CREATE/UPDATE Procedure for ODATA SERVICES?????

Pr_Create_Update procedure

PROCEDURE"shema"."folder.subfolder.procedures::prcedurename_create_update" (

INrow"catalog table which you want",

              OUTerror"table_type for error message::error")

       LANGUAGESQLSCRIPT

       SQLSECURITYINVOKER

       DEFAULTSCHEMA"schema name"

AS
