RE: QSQGNDLL API / RTVSQLSRC

... but keep in mind the logicals (built on the physical) have to be changed to point on the new SQL table and recreated!

There is a trick that you can use. I am not sure where it is documented on-line. Maybe somebody knows.

Trick is that you create a new SQL defined table with long names and maybe identity keys. You then create a logical file pointing to the new table you have created. That logical should have all the existing fields of the current physical file and should have the same record format id as the existing physical file.

In other words, all the existing programs see the logical and think it is the old physical and since it has the same format and record level id there is no error. You have the new SQL defined tables but existing programs are using the logical.

Perhaps you rather should go for the SQL services (that wraps the
API

you

are describing)

call qsys2.generate_sql_objects('INORDER','QTEMP',
database_source_file_name => output_file,
database_source_file_library_name => output_library,
database_source_file_member => output_file,
replace_option => '1',
--statement_formatting_option =>
--date_format =>
create_or_replace_option => '1',
qualified_name_option=>'1'
);

I am using it here in my gist:
