In productive use, it is this @Environment.systemField annotation which takes effect. In open SQL we do not need to explicitly pass value to these two parameters.
See following ABAP code: all products created by Jerry are fetched, although no parameter for user name is passed.
data: lt_result TYPE TABLE OF Zproductdescription.
SELECT * FROM Zproductdescription INTO TABLE @lt_result .
You can verify via ST05 that ABAP runtime automatically fills these two parameter for you:
