RE: SQL: SET OPTION DYNUSRPRF

Apparently the answer is yes, I do need to use the SET OPTION

So far in my testing I've found that
ctl-opt usrprf(*owner);
is interchangeable with
exec sql set option usrprf=*owner;
I can use one or the other.

What gets to be the issue is if there is any dynamic SQL such as EXECUTE

exec sql prepare STMT1 from :SQLSTMT;
exec sql execute STMT1;
Then I need the
Exec sql set option dynusrprf=*owner;
also.

Now I'm trying to find out if there's a way to do this after the fact

ctl-opt usrprf(*owner);
or
exec sql set option usrprf=*owner;
I can simply run CHGPGM PGM(...) USRPRF(*OWNER)

Is there something similar to fix DYNUSRPRF?
PRTSQLINF OBJ(ROB/SECTEST) will tell me the value of this option, but is
