从现有数据库表创建内部表的语法? [英] Syntax for creating internal table from existing database table?

问题描述

我是 ABAP 的新手.开始学习内部表.我正在阅读创建内部表的方法.

I'm new to ABAP. Started learning about internal tables. I was reading on the ways to create internal tables.

我使用以下语法从现有数据库表创建内部表:

I came across the following syntax to create an internal table from an existing database table:

data: it_mara type table of mara.

我很困惑，因为 mara 是一张桌子，如果 l.h.s 和 r.h.s 是同一类型，那么它不应该只是:

I'm confused since mara is a table and if both l.h.s and r.h.s are of the same type then shouldn't it be just:

data: it_mara type mara.

mara已经是table了，还需要什么转换成table?

What is the need to convert mara into a table when it is already a table?

推荐答案

MARA 是一个透明的表，这意味着它与结构类型 MARA 同时起作用.这就是 SAP 的工作方式.:)

MARA is a transparent table which means that it functions at the same time as the structure type MARA. This is the way SAP works. :)
