数据库视图是SAP中实现多表关联查询的基础工具,适合简单的跨表查询和权限控制场景。但其功能有限,对于复杂逻辑或高性能需求,建议结合CDS视图或ABAP程序开发。通过合理设计,数据库视图可显着提升开发效率和系统可维护性。
Database views are defined in the ABAP Dictionary. The system automatically creates a database view in the underlying database when you activate the view.FeaturesApplication programs can access the data of a database view using the database interface. You can access the data in ABAP programs ...
1.)AMDP - ABAP管理数据库程序,是一种程序,我们可以使用SQLSCRIPT在AMDP内部编写代码,SQLSCRIPT是一种与SQL脚本相同的数据库语言,这种语言易于理解和编码。 将AMDP方法内的逻辑编码后,可以在ABAP报表中使用,也可以在CDS Table Function中使用AMDP方法。 2.)使用AMDP,可以将ABAP Application编写的代码通过HANA的新特...
All access types (with the exception of AMDP) also enable access to other databases using additional connections (except for access to the central database of an AS ABAP (standard connection)). Note For calls of database procedures of an SAP HANA database, there is also the statementCALL DA...
Keep in Mind that SAP IQ is not the primary Database here, where the Application Data is stored, it is the secondary Database where the mentioned Objects from above stored for anytime fast access outside the primary Database for shrinking the main Database, e.g. SAP HANA. SAP IQ can ...

1. ABAP Memory 用户登陆后,最多一个系统可以开6个窗口,这在SAP中称为External Mode。 而同一个窗口中,运行某程序后,可以通过CALL TRANSACTION/SUBMIT或其他代码跳转到其他程序,这个称为Internal Mode。Internal Mode的调用栈最多为9层。 那么ABAP Memory,它是属于Internal Mode间可以共享的数据,而External Mode间...

SAP ABAP Database Tables SAP ABAP database tables are collection of fields, in which fields are made up of columns and rows. In SAP more than 8000 tables are defined. When table is created, its columns are named and data type is supplied for each columns. There can be only one data ...
ABAP托管数据库过程(ABAP-Managed Database Procedure,以下简称AMDP)是在APAP on SAP HANA开发中的一种优化模式。AMDP使用数据库语言书写,比如Native SQL或者是SQL Script,并且在AMDP类的AMDP方法内实现。因此用它开发数据库过程就有点类似于编辑ABAP类。
