本文阐述了ABAP CDS association的概念,并且展示了在CDS视图中和SQL语句中写路径表达式(Path Expression)代码的方法。我也会解释如何在CDS asociation中指定inner join——默认情况下是left outer join,以及如何为association添加过滤。 对于CDS的相关开发,SAP希望我们使用association而不是join,因为association更加接近“概念思...

The new ABAP annotation AbapCatalog.compiler.compareFilter can be used to specify whether the filter conditions are compared for the path expressions of a view. In this case, the associated join expression is evaluated once only, if the same filter condition occurs. Modification...
When a CDS view is activated, a join defined by an association is built for every use in a path expression and not for the definition of the association. No joins are constructed for associations that are not used in their CDS views. ...
