SAP ABAP Select 查询

Question

I am working through an SAP textbook to learn more about the systems and how to interact with them for work. I am very new to SAP and I don't really understand this question. Could someone please explain and help me understand what is going on here?

Answer 1

Some rows in valueTable have corresponding rows in textTable with language EN , for example ID 1 , while others have not, for example ID 2 .

You are asked to write a SELECT statement that joins the two tables such that only the values with English text are selected, ie this should be the result:

id | value1 | value2 | text
---| ------ | ------ | ------
 1 |    A   |   11   | Foobar
 3 |    C   |   13   | bar

The question can be answered with basic understanding of SQL, esp. JOINs, and does not require specific ABAP know how.
