Is there any query by which we can identify / know about which SQL statement/data is captured/ propagated / applied in streams environment.

No, you only have SCN in DBA_CAPTURE and others and in case of apply error, you can get the LCR with dbms_apply_adm...

Hi Arju,

I have used the following procedures taken from the 9i streams manual.

CREATE OR REPLACE PROCEDURE print_any
     (data  IN sys.anydata)
IS
  tn   VARCHAR2(61);
  str  VARCHAR2(4000);
  chr  CHAR(255);
  num  NUMBER;
  dat  DATE;
  rw   RAW(4000);
  res  NUMBER;
BEGIN
  IF data IS NULL  THEN
    dbms_output.put_line('NULL value');
    
    RETURN;
  END IF;
  
  tn := data.gettypename();
  
  IF tn = 'SYS.VARCHAR2' THEN
    res := data.getvarchar2(str);
    
    dbms_output.put_line(str);
  ELSIF tn = 'SYS.CHAR' THEN
    res := data.getchar(chr);
    
    dbms_output.put_line(chr);
  ELSIF tn = 'SYS.VARCHAR' THEN
    res := data.getvarchar(chr);
    
    dbms_output.put_line(chr);
  ELSIF tn = 'SYS.NUMBER' THEN
    res := data.getnumber(num);
    
    dbms_output.put_line(num);
  ELSIF tn = 'SYS.DATE' THEN
    res := data.getdate(dat);
    
    dbms_output.put_line(dat);
  ELSIF tn = 'SYS.RAW' THEN
    res := data.getraw(rw);
    
    dbms_output.put_line(rawtohex(rw));
  ELSE
    dbms_output.put_line('typename is '

you can use the print_transaction procedure with the SCN number from dba_capture.

In addition, instead of posting the whole procedure just post the link.
