It appears that dbms_sql.parse executes the actual CURSOR in 10g.
I'm guessing this is expected behavior even though DBMS_SQL has a separate EXECUTE procedure?
SQL> create table test1
2 (val1 number)
3 /
Table created.
SQL> declare
2 cursor_name INTEGER;
3 BEGIN
4 cursor_name := dbms_sql.open_cursor;
5 DBMS_SQL.PARSE(cursor_name, 'drop table test1', DBMS_SQL.NATIVE);
6 DBMS_SQL.CLOSE_CURSOR(cursor_name);
7 EXCEPTION
8 WHEN OTHERS THEN
9 DBMS_SQL.CLOSE_CURSOR(cursor_name);
10 raise;
11 END;
12 /
PL/SQL procedure successfully completed.
SQL> select * from test1
2 /
select * from test1
*

Hi Chris,
take a look at DBMS_SQL.Parse() - if you want to do it in PL/SQL that is. For other tools such as Perl, C++, etc, then it's all down to what options the tool itself provides in its Oracle Interface utilities.
HTH
Cheers,
Norm.

Subject: Developer question
I'm forwarding this to the list because I don't know an answer off
the top of my head and Google isn't being much help due to the nature
of the search.
Developer wants to know if you can prepare a statement in a string
variable like 'execute someproc();' and check the validity of the
statement without executing it. (PARSE it only)
I *thought* there was a way in Oracle to parse a statement without
executing it but I can't figure it out at the moment.
