Laura,  

Here's one. In this case, if the in variable 'p_actualenddate' is passed into the procedure, and additional 'and' clause is added to the where clause. Any questions, give me a shout.  

PROCEDURE ListScheduleforDelete

(

               p_employid         IN VARCHAR2,
               p_status             IN
WTW_EMPL_WEEKENDING_SCHEDULE.SCHED_STATUS_CODE%TYPE,
               p_actualenddate  IN
WTW_EMPLOYMENT.EMPLOYMENT_START_DATE%TYPE,
               p_refCursor         IN OUT empRS

)
IS
sel_string VARCHAR2(2000) :=

' SELECT WTW_EMPL_WEEKENDING_SCHEDULE.EMPLOYMENT_ID, ' ||
' WTW_EMPL_WEEKENDING_SCHEDULE.EMPLOYMENT_WEEKEND_DATE, ' ||
' WTW_EMPL_WEEKENDING_SCHEDULE.TOTAL_ACTUAL_HRS_NBR, ' ||
' WTW_EMPL_SCHED_STATUS_CODE.SCHED_LONG_TXT, ' ||
' WTW_EMPL_WEEKENDING_SCHEDULE.TOTAL_SCHED_HRS_NBR ' ||
' FROM WTW_EMPL_WEEKENDING_SCHEDULE, WTW_EMPL_SCHED_STATUS_CODE ' ||
' WHERE WTW_EMPL_WEEKENDING_SCHEDULE.EMPLOYMENT_ID = :p_employid AND ' ||
' WTW_EMPL_WEEKENDING_SCHEDULE.SCHED_STATUS_CODE = :p_status AND ' ||
' WTW_EMPL_SCHED_STATUS_CODE.SCHED_STATUS_CODE(+) =
WTW_EMPL_WEEKENDING_SCHEDULE.SCHED_STATUS_CODE ';   where_string VARCHAR2(400);  

where_str VARCHAR2(7) := ' AND ';  

ActualDatePlusSeven DATE;  

BEGIN
IF p_actualenddate IS NOT NULL THEN

   ActualDatePlusSeven := p_actualenddate + 7;    where_string := where_str || '
WTW_EMPL_WEEKENDING_SCHEDULE.EMPLOYMENT_WEEKEND_DATE >= ' ||

                           '''' || ActualDatePlusSeven || '''' || ' ';

END IF;   OPEN p_refCursor FOR

          sel_string ||
          where_string ||
          ' ORDER BY 2 DESC' USING p_employid, p_status;
 

END ListScheduleforDelete;

We have Oracle version 8.0.5 and need to use dynamic sql. Through research I know that there is a dbms_sql package that is suppose to support this, but we cannot find an example of what we are needing to do. We have been told that we can do it easily in '8i' but we are not able to upgrade yet.

We are trying to populate a reference cursor via a procedure with a select statement. Has anyone done this and if so can you furnish an example? I may need to tell more about what we are doing and if so please tell me.

Thank you,

Laura
