Isn't it wonderful how one silly programmer using a hammer to drive in a
screw leads to an elaborate discussion of all the technical aspects of the
hammer? Just give that programmer a screwdriver.

Combining a primary file with sloppy dynamic SQL sounds more like an April
Fools' Day prank.

I don't understand the use of this embedded sql instead of using a
CHAIN operation. Hopefully someone will explain.

A file is read by the RPG cycle (primary file) and the subroutine
is called for every record of the file.
This file contains a couple of hundred thousand records.

It seems to me that this is the equivalent of opening myfile for
each subroutine call, reading every record in the file then closing
the file again.
Although I'm not sure about the reading. Is the whole file read at
the open cursor statement?

Myfile has a couple of hundred records. For the whole primary file
only about 10 different values for someDateField will be used.
