 ## Using Native Features  { #native-db-functions}
 
 In general, the CDS 2 SQL compiler doesn't 'understand' SQL functions but translates them to SQL generically as long as they follow the standard call syntax of `function(param1, param2)`. This allows you to use native database functions inside your CDS models.
