Configuration of this variable is not possible. Because sqlite3 does not enforce type or size constraints on data inserted. $at is a structured element with two subelements from and to. The $at variable is used in the context of temporal data, but it can also be used independently. Configuration of this variable is not possible. The variable does not have any child properties.

The $now variable can be used to reference the current timestamp.

The $session variable (and any arbitrary child properties) are accepted during compilation, but without a valid configuration they will lead to errors when generating database artifacts. There is also the possibility to use arbitrary child properties - but without a valid configuration, those will lead to an error when compiling into database artifacts. For dialect plain and sqlite, the default locale en is used for $user.locale. The variables $user and $user.id are only supported for HANA out-of-the-box - for other database dialects, they need to be configured. $user is a shortcut for $user.id as $user. The $user variable can be used as-is, or it's child properties id and locale can be used. [įor different databases, different replacement values need to be defined.

They must start with a header line that lists the needed element names.Ĭsv ID records.

Pattern for nested entities: .Įxamples: my.bookshop-Books.csv, or my.

File names must follow the pattern namespace-entity.csv.

Each file contains data for one entity.

These files will be treated as native SAP HANA artifacts and deployed as they are.

db/src/** folder for CSV files and corresponding hdbtabledata files.

csv or data subfolder related to a CDS model file, including db/csv and db/data folders.

cds build will copy these files into the application's deployment folder. This also includes CSV files of reuse modules. Initial data is only fetched, if the corresponding entity is contained in your compiled model. CSV files can be defined in any csv or data subfolder, including db/data and db/csv. The locations of CSV files are determined based on the location of CDS model files.

If you've accidentally deployed such data to a productive database, see this troubleshooting entry on how to recover from this situation. CSV files in your project are picked up by deployments for both SQLite and SAP HANA.
