● Defined data to expose with the OData application, for example, at least the following: ○ A database schema ○ A database table 1. In the shared project you are using for your OData application, use the Project Explorer view to locate the package where you want to create the new OData service definition. Note: The file containing the OData service definition must be placed in the root package of the OData application for which the service is intended. 2. Create the file that will contain your OData service definition. In the Project Explorer view, right-click the folder where you want to create the new OData service-definition file and choose New File in the context-sensitive popup menu. 3. Define the OData service. The OData service definition uses the OData Service Definition Language (OSDL), which includes a list of keywords that you specify in the OData service-definition file to enable important features. The following example shows a simple OData service definition exposing a simple table: service namespace "my.namespace" { "sample.odata:table.hdbtable" as "MyTable"; } This service definition exposes a table defined in the file sample.odata:table.hdbtable and creates an EntitySet for this entity named MyTable. The specification of an alias is optional. If omitted, the default name of the EntitySet is the name of the repository object file, in this example, table. 4. Place the valid OData service definition in the root package of the OData application to which it applies. 5. Save, commit, and activate the OData service definition in the SAP HANA repository. Related Links OData Service Definitions [page 165] The OData service definition is the mechanism you use to define what data to expose with OData, how, and to whom. Data exposed as an OData collection is available for analysis and display by client applications, for example, a browser that uses functions provided by an OData client library running on the client system. 8.1.7 OData Service Definition Language Syntax The OData Service Definition Language (OSDL) provides a set of keywords that enable you to set up an ODATA service definition file that specifies what data to expose, in what way, and to whom. The following list shows the syntax of the OData Service Definition Language (OSDL) in an EBNF-like format; conditions that apply for usage are listed after the table. definition :='service' [namespace] body namespace :='namespace' quotedstring quotedstring :=quote string quote string :=UTF8 quote :='"' body :='{' content '}' content :=entry [content] entry :=( entity | association ) ';' entity :=object [entityset] [with] [keys] [navigates] [aggregates] [parameters] 184 P U B L I C © 2012 SAP AG.
