DBMS_SQL.FETCH_ROWS

Question

Hi,
I am seeing a strange thing. See the below code snippet.
v_qry := 'select count(1) from emp where ename = ''SCOT''';
DBMS_OUTPUT.PUT_LINE(V_QRY);
DBMS_SQL.PARSE (cur, v_qry, DBMS_SQL.NATIVE);
int_output := DBMS_SQL.EXECUTE (cur);
int_exec := DBMS_SQL.FETCH_ROWS (cur);
as no row with ename ='SCOT' exists, the int_exec should be 0. It shows 1.

Answer 1

the int_exec should be 0. It shows 1.Check this:
SQL> set serverout on
SQL> DECLARE
   cur          INT := dbms_sql.open_cursor ();
   int_output   INT;
   int_exec     INT;
   val_out      INT;
   v_qry        VARCHAR2 (100);
BEGIN
   v_qry := 'select count(1) from emp where ename = ''SCOT''';
   dbms_output.put_line (v_qry);
   dbms_sql.parse (cur, v_qry, dbms_sql.native);
   int_output := dbms_sql.execute (cur);
   dbms_sql.define_column (cur, 1, val_out);
   int_exec := dbms_sql.fetch_rows (cur);
   dbms_sql.column_value (cur, 1, val_out);
   dbms_output.put_line (int_exec);
   dbms_output.put_line (val_out);
   dbms_sql.close_cursor (cur);
END;
select count(1) from emp where ename = 'SCOT'
