pl/sql - Using a dynamic query inside a stored procedure

Question

I am using a stored procedure to insert data into a temp table using a cursor. This procedure stores a dynamic query inside a variable to mount the insert/update command.

Answer 1

I am using Oracle 11g , last couple of day I was facing problem of execute dynamic query in oracle procedure. I did search lots off. finally i have got solution .

-- In blow procedure we pass multiple argument at run time 
-- We need reference cursor for dynamic query execution
create or replace  PROCEDURE FETCH_REPORT1_NEW(IPID IN number ,CAID IN number,
ZOID IN  number,CLID IN number,SDATE VARCHAR2 , EDATE
VARCHAR2,OUT_VALUE OUT VARCHAR2)

IS

  l_sql varchar(200);   TYPE cursor_ref IS REF CURSOR;   c1
cursor_ref;

  UZID transaction_data.zone_id%TYPE;   OUTAGE_MINS
transaction_data.durationmin%TYPE;

BEGIN

    l_sql := 'select  Avg (durationmin) , zone_id ,
     from transaction_data where  alarm_id in (1,21,26,20) and  zone_id not in(5)';

      IF IPID>0 THEN  

       l_sql := l_sql||' and  IP_ID = '||IPID;

      END IF;         


        l_sql := l_sql||' group by (zone_id)';
       open c1 for l_sql;

          loop
              fetch c1 into OUTAGE_MINS,UZID;

                       dbms_output.put_line(OUTAGE_MINS||UZID);

              exit when c1%notfound;

          end loop;
     close c1; 
    END;
