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...
After a piece of CDS source code is transported, the combination of its name and the name of the CDS table function view is defined and can no longer be modified by being renamed. Example The following DDL source code shows aclient-specificCDS table function. It contains an input parameter ...
ABAP CDS Table Function 在ABAP CDS Table Function的开发过程中,我们将字段结构、参数(可选)、association等通过类/方法定义为实体。通过AMDP我们可以直接在ABAP层写存储过程,并且把它封装在类/方法中,更多介绍可以看之前的文章:ABAP中的AMDP(ABAP-Managed Database Procedures。 因为AMDP直接运行数据库脚本,所以需...
ClientDependent Defines client handling when Open SQL is used to access the CDS table function (obsolete). true: The CDS table function is client-specific. When accessed using SELECT, automatic client handling is performed. false: The CDS table function is a cross-client table function. No auto...
