DBMS_SQL.PARSE EXECUTES the cursor? (was Re: Developer question)

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.
