## Standard Database Functions

A specified set of standard functions - inspired by [OData](https://docs.oasis-open.org/odata/odata/v4.01/odata-v4.01-part2-url-conventions.html#sec_StringandCollectionFunctions) and [SAP HANA](https://help.sap.com/docs/hana-cloud-database/sap-hana-cloud-sap-hana-database-sql-reference-guide/alphabetical-list-of-functions?locale=en-US) - is supported in a **database-agnostic**, hence portable way, and translated to the best-possible native SQL functions or polyfills during runtime (currently only Node.js) and for your CDL files.

The functions are translated to the best-possible native SQL functions or polyfills during runtime and also during compilation of your CDL files.


### OData standard functions

The `@sap/cds-compiler` and all CAP Node.js database services come with out of the box support for common OData functions.
