在常规的ABAP CDS内我们可以使用CONCAT函数,但是使用它的时候,我们需要定义固定数量的字段,既然CDS视图不能实现此处需要的处理动态逻辑,要如何处理呢? 这是一个使用ABAP CDS Table Function的绝佳场景,因为我们可以使用简单的数据库函数STRING_AGG(String Aggregation)。这个功能在SQL Script中可用,但是目前还是不支持ABAP...

In the following listing, a client-specific ABAP CDS table functionTAB_FUNCTION_EXAMPLEis defined using the DDL syntax. This table function declares two input parametersclnt(with the predefined value: #CLIENT) andcarrid, and a list of elements that provide the return values of the AMDP method ...
注意:table function应永远有返回参数,所以记着在最后一个SELECT语句前放一个RETURN语句。另外,注意我们将字段名转换为前文中ABAP CDS Table Function声明的字段名,如果你没有提供一个合适的别名,激活的时候编译器会给出提示。 类ZCL_FLIGHTS_DEMO_CDS的最终版本是这样的: CLASS zcl_flights_demo_cds DEFINITION PUB...
