Execute Different SQL Statements Based On Day of Week

Question

I need to execute different sql statements based on the day of the week in Oracle 8i. In SQL Server, it's pretty simple. SELECT
CASE DATEPART(dw,GETDATE())
WHEN 4 THEN (SELECT COUNT(*) FROM ADR_VLDN )
END
In Oracle it should be something like this
IF to_char(SYSDATE, 'D') = 2 THEN
SELECT * FROM RSVP_FILE_PRCS WHERE ROWNUM = 1;
ELSEIF to_char(SYSDATE, 'D') = 3 THEN
SELECT * FROM RSVP_FILE_PRCS WHERE ROWNUM = 2;
END IF;
But this doesn't work. Does anyone have any ideas about how to do this in Oracle?

Yes, but I don't want to create 7 different jobs, one for each day of the week. Isn't there a way to do this in PL/SQL? It took me 10 seconds in SQL Server's TSQL.Yes you keep showing some TSQL syntax that obviously does not do what you are asking for.

ENDSo the equivalent in Oracle would be
SQL> var n number
SQL> begin
  2    if to_char(sysdate,'D') = '4' then
  3      select count(*) into :n from dual;
  4    end if;
  5  end;
  6  /
PL/SQL procedure successfully completed.
SQL> print n
         N
