Re: Newbie question: SQL*Plus command to see number of query result rows

You are asking if it´s possible to remove the basic function of Sql*plus.

You can remove the header "STUDENT_ID" using this command: set heading off; And you can remove all feedbacks ie. "3 rows selected" by using this command: set feedback off;

But you can not remove the results, since they are the once you are requesting in your select statement.

Why not use:
 select count(1) from ( your joined statement );

Or try using a cursor.

You can cut script below and save it to <name>.sql and execute it in Sql*plus.
Remember to replace <Your joined statement.> with, well guess...¨

• CUT ---- set serveroutput on

Declare

Cursor A1 is
 <Your joined statement.>

r1 A1%rowtype;

cnt number;

Begin

 cnt := 0;

 Open A1;
  Loop
   Fetch A1 into r1;
   Exit when A1%notfound;

    cnt := cnt + 1;

   End loop;

 Close A1;

 dbms_output.put_line('Result: '||cnt);

End;
/
---- END CUT ---- Regards
