Current CDS files

Hi,

A couple of weeks ago reading through the blog, I read that the .hdbcds files are depreciated now and that the files in the tutorial where re written in hdbtable files.

But reading the “SAP HANA Core Data Services (CDS) Reference” guide, they talk about .hdbdd files. And migrating documents to this file types.

I am working with the SAP HANA Express 2.00.045 version and the associated WEBIDE; there are no options for hdbdd files. Just HDB CDS Artifacts and New Database Artifacts like hdbtables.

Which is the version to be used?

Do we have to wait for the hdbdd file extension to be added to the SAP HANA EXPRESS Edition?

Best Regards

    HDBDD has been deprecated for many years. It only exists in HANA Repository/XS Classic. It was already removed back in HANA 1.0 SPS 11 from HDI based development. I don't know what you are reading that talks about hdbdd, but its obviously a very old document.

    HDBCDS replaced HDBDD in HANA 1.0 SPS 11 when moving to HDI. However HDBCDS has now been deprecated as well. HDBCDS has already been removed from HANA Cloud (HANA version 4.0).

    If you want CDS syntax, then please use CAP and the .CDS extension. When you build CAP projects it will compile to HDBCDS by default (as it has for the past 2 years). However there is a new configuration option you can set in the package.json at the root of your project which will tell CAP to compile to HDBTABLE/HDBVIEW instead for full compatibility with HANA Cloud. This is detailed in the CAP Documentation here: https://cap.cloud.sap/docs/guides/databases#hana-cloud
