Looks like it's working in oranif. I'll see what the issue it in dderl.

Can't reproduce, I tried following escript:
#!/user/bin/escript

-include_lib("eunit/include/eunit.hrl").
-define(DPI_MAJOR_VERSION, 3).

-define(TNS, <<>>).
main([]) ->
dpi:load_unsafe(),
Context = dpi:context_create(?DPI_MAJOR_VERSION, ?DPI_MINOR_VERSION),
Conn = dpi:conn_create(
Context, <<"foo">>, <<"bar">>, ?TNS,
#{encoding => "AL32UTF8", nencoding => "AL32UTF8"}, #{}
),
Sql = <<"BEGIN
:VARCHAR2_OUT_RESULT := pong(:VARCHAR2_IN_PING);
END;">>,
Stmt = dpi:conn_prepareStmt(Conn, false, Sql, <<>>),
[ok, ok] = [begin
#{var := VarCol} = dpi:conn_newVar(
Conn, 'DPI_ORACLE_TYPE_VARCHAR', 'DPI_NATIVE_TYPE_BYTES', 10,
10, true, false, null
),
dpi:stmt_bindByName(Stmt, X, VarCol)
end || X <- [<<"VARCHAR2_OUT_RESULT">>, <<"VARCHAR2_IN_PING">>]],
?assertException(error, {error, _File, _Line,
#{message := "ORA-06550: line 2, column 39:\n"
"PLS-00201: identifier 'PONG' must be declared\n"
"ORA-06550: line 2, column 15:\n"
"PL/SQL: Statement ignored"}},
dpi:stmt_execute(Stmt, [])
),
io:format("Test successful.~n"),
halt(1).

ok, I think I understand the problem. It's not an oranif issue, but a dderl issue. If oranif returns an error in a certain place, the error message is discarded. I created a fix for the issue in dderl.
As for the second part, what should the result be? As it is currently, the internal type of the statement is not a query, hence why no result is shown.

I'm still trying to figure out all the PL/SQL syntax, but I made a demo where a function is created and then called.

@KarlKeiser Our SQL parser does not support the create statement but DDerl still gives it to the DB to execute. Everything fine here now.
